SpringBoot框架用了这么久了，今天就来总结一下
SpringBoot的优点和特性这里就不说了，我今天要结合Redis和MyBatis和Lombook来搭建一个简单的SpringBoot框架。
首先我们从创建一个SpringBoot项目开始，当然，我用的项目管理工具是maven
版本信息：
SpringBoot > 2.0.3
Maven > 3.5.3
JDK > 1.8
上图是刚创建好的SpringBoot项目的初始结构
接下来需要将项目所需的包配置在pom.xml文件中：
文中已加了详细的注解：

pom.xml文件配置文成后，右键项目，店家maven–Update Project…，项目会自动下载所配置的jar包。
完成后，需要先准备一些工具类：
redis操作类：如图是目录结构
这三个类是操作redis的工具类。
下面贴上代码：
package com.gnayey.common.staticconf;
//用来从配置文件获取redis的链接信息
public class SystemStartupValue {
public static String REDIS_IP;
public static Integer REDIS_PORT;
}
package com.gnayey.redis;
import org.apache.commons.configuration.Configuration;
import org.apache.commons.configuration.ConfigurationException;
import org.apache.commons.configuration.PropertiesConfiguration;
import com.gnayey.common.staticconf.SystemStartupValue;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
public class JedisPoolUtil {
private static volatile JedisPool jedisPool = null;
private JedisPoolUtil() {
}
public static JedisPool getJedisPoolInstance() {
if(jedisPool == null) {
synchronized (JedisPoolUtil.class) {
if(jedisPool == null) {
Configuration conf = null;
try {
conf = new PropertiesConfiguration("config.properties");
} catch (ConfigurationException e) {
e.printStackTrace();
}
// 池基本配置
JedisPoolConfig config = new JedisPoolConfig();
config.setMaxIdle(conf.getInt("maxIdle"));
config.setMaxWaitMillis(conf.getInt("maxWaitMillis"));
config.setTestOnBorrow(conf.getBoolean("testOnBorrow"));
config.setMaxTotal(conf.getInt("maxTotal"));
if(SystemStartupValue.REDIS_IP!=null && SystemStartupValue.REDIS_PORT!=0){
jedisPool = new JedisPool(config, SystemStartupValue.REDIS_IP, SystemStartupValue.REDIS_PORT);
}else{
jedisPool = new JedisPool(config, conf.getString("host"), conf.getInt("port"));
}
}
}
}
return jedisPool;
}
public static void release(JedisPool jedisPool, Jedis jedis) {
if(jedis != null) {
jedisPool.returnResource(jedis);
}
}
}
RedisClient 类的内容为操作redis的具体方法，也可以添加方法来满足自己的业务
package com.gnayey.redis;
import java.util.List;
import java.util.Map;
import java.util.Set;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import org.apache.commons.configuration.ConfigurationException;
public class RedisClient {
private Jedis jedis;// 非切片额客户端连接
private JedisPool jedisPool = JedisPoolUtil.getJedisPoolInstance(); //非切片数据库连接池
public RedisClient() {
synchronized (this) {
if(jedis == null) {
jedis = jedisPool.getResource();
}
}
}
/**
* 关闭资源
*/
public void closeResource(){
if(jedis != null) {
try {
JedisPoolUtil.release(jedisPool, jedis);
} catch (Exception e) {
}
}
}
/**

* @param key
* @return
*/
public String getValue(String key) {
String str = jedis.get(key);
return str;
}
/**
* 获取List全部集合
* @param key
* @return
*/
public List<String> getList(String key) {
List<String> list = jedis.lrange(key, 0, -1);
return list;
}
/**
* 获取List集合中一部分,start:开始下标(list从0开始计数),end:结束下标(填写-1表示获取全部list)
* @param key
* @param start
* @param end
* @return
*/
public List<String> getList(String key, int start, int end) {
List<String> list = jedis.lrange(key, start, end);
return list;
}
/**
* 获取指定下标的list数据
* @param key
* @param index
* @return
*/
public String getListByIndex(String key, int index) {
String str = jedis.lindex(key, index);
return str;
}
/**

* @param key
* @return
*/
public Set<String> getSet(String key) {
Set<String> set = jedis.smembers(key);
return set;
}
/**
* 检查content是否存在于key集合中
* @param key
* @param content
* @return
*/
public boolean isInSet(String key, String content) {
boolean bool = jedis.sismember(key, content);
return bool;
}
/**

* @param key
* @return
*/
public List<String> getHashVal(String key){
List<String> list = jedis.hvals(key);
return list;
}
/**
* 判断conent是否在key的hash中时候存在
* @param key
* @param content
* @return
*/
public boolean isInHash(String key, String content){
boolean bool = jedis.hexists(key, content);
return bool;
}
/**
* 获取hash中字段为contents1,contents2...的值
* @param key
* @param contents
* @return
*/
public List<String> getHash(String key,String ... contents){
List<String> list = jedis.hmget(key, contents);
return list;
}
/**
* 获取hash为key的某一字段
* @param key
* @param content
* @return
*/
public String getHashVal(String key, String content) {
String str = jedis.hget(key, content);
return str;
}
/**

* @param key
* @return
*/
public Set<String> getHashKeys(String key){
Set<String> set = jedis.hkeys(key);
return set;
}
/**
* 获取hash中所有的key
* @param key
* @return
*/
public Set<String> getKeys(String key){
Set<String> set = jedis.keys(key);
return set;
}
/**
* 获取指定hash表中指定字段的value
* @param key
* @param field
* @return
*/
public String getHashValueByKey(String key, String field) {
String str = jedis.hget(key, field);
return str;
}
/**
* 获取指定hash表中所有字段
* @param key
* @return
* @throws ConfigurationException
*/
public Map<String, String> getHash(String key){
return jedis.hgetAll(key);
}
public String setHash(String key, Map<String, String> map){
return jedis.hmset(key, map);
}
public void setHashAndTime(String key, Map<String, String> map,int times){
jedis.hmset(key, map);
jedis.expire(key, times);
}
public long del(String key) {
long lon = jedis.del(key);
return lon;
}
/**
* 获取非切片额客户端连接,当其余接口不能解决开发问题时,使用此接口解决redis读取问题。具体查看jedis官方api
* @return
*/
public Jedis getJedis() {
return jedis;
}
}
在resoures文件夹下创建application.properties
内容如下：
server.port=8099
#配置数据源
spring.datasource.url=jdbc:mysql://localhost:3306/sys?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=UTC
spring.datasource.username = root
spring.datasource.password = 123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#配置MyBatis的xml文件路径
mybatis.mapper-locations: classpath:/mapper/*Mapper.xml
再创建一个config.properties文件，用来配置项目中用到的一些公共配置，比如：文件服务器地址，redis链接信息等，下面是我写的一些内容：
#######################################################redis config###############################################################
maxIdle=1000
maxTotal=1000
maxWaitMillis=10000
testOnBorrow=false
host=10.0.0.30
port=6379
name=master
file_server_ip=10.0.0.30
file_server_port=22
fole_server_user=root
file_server_password=qwe123
接下来需要创建一个MyBatis的xml文件映射的目录，也就是在application.properties里面配置的：mybatis.mapper-locations: classpath:/mapper/*Mapper.xml
如下图：
mapper内放置的就是你的xml文件
接下来，创建一个启动类GnayEyApplication.java和Swagger.java类
如下
package com.gnayey.startup;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@EnableTransactionManagement(proxyTargetClass = true)
@EnableSwagger2
@ComponentScan(basePackages = "com.gnayey.exception")
@ComponentScan(basePackages = "com.gnayey.controller")
@ComponentScan(basePackages = "com.gnayey.service")
@MapperScan("com.gnayey.mapper")
@SpringBootApplication
public class GnayEyApplication {
public static void main(String[] args) {
SpringApplication.run(GnayEyApplication.class, args);
}
}
package com.gnayey.startup;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
public class Swagger2 implements WebMvcConfigurer {
// 接口版本号
private final String version = "1.0";
// 接口大标题
private final String title = "GnayEyTestProject";
// 具体的描述
private final String description = "公共数据服务接口文档";
// basePackage
private final String basePackage = "com.gnayey.controller";
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage(basePackage))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title(title)
.description(description)
.version(version)
.build();
}
}
目录结构如下：
到这，一个SpringBoot框架就完成了，下面我们写一个登陆接口，并给项目配置拦截器，使用redis来保存用户登陆信息。直接上代码：
拦截器配置类：如上图中的WebAppConfig.java
package com.gnayey.startup;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import com.gnayey.interceptor.InterceptorConfig;
@EnableWebMvc
@Configuration
public class WebAppConfig implements WebMvcConfigurer {
@Bean
InterceptorConfig localInterceptor() {
return new InterceptorConfig();
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(localInterceptor())
.addPathPatterns("/v1/**")
.excludePathPatterns("/v1/login/**/")//配置登陆接口不被拦截
.excludePathPatterns( "/swagger-ui.html/**");//配置swagger地址不被拦截
WebMvcConfigurer.super.addInterceptors(registry);
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
下面是拦截器的具体实现，里面是写你的具体业务
package com.gnayey.interceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
public class InterceptorConfig implements HandlerInterceptor {
@Autowired
private GnayeyLoginServicegnayeyLoginService;*/
/**
* 进入controller层之前拦截请求
* @param httpServletRequest
* @param httpServletResponse
* @param o
* @return
* @throws Exception
*/
@Override
public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
//获取前端tocken
String token = httpServletRequest.getParameter("token");
if(token != null) {
if(token.length() > 0) {
SchoolfellowUserLoginResVo schoolfellowUserLoginRepVo = schoolfellowLoginService.getLoginedUserInfo(token);
if (schoolfellowUserLoginRepVo == null) {
return false;
} else {
return true;
}
}
}
return false;
}
@Override
public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
}
@Override
public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {
}
}
下面是DAO类，其中包含了Lombok的用法，
Lombok的用法参考：
https://www.cnblogs.com/heyonggang/p/8638374.html
package com.gnayey.entity;
import lombok.Getter;
import lombok.Setter;
public class SysUserInfoDo {
@Getter
@Setter
private String id;
@Getter
@Setter
private String loginName;
@Getter
@Setter
private String userName;
}
下面是mapperj接口
package com.gnayey.mapper;
import org.apache.ibatis.annotations.Mapper;
import com.gnayey.entity.SysUserInfoDo;
@Mapper
public interface SysUserInfoMapper {
/**
* 根据用户登录名和密码查询
* @param loginName password
* @return
*/
SysUserInfoDo selectByLoginNameAndPassword(@Param("loginName")String loginName, @Param("password")String password);
}
下面是MyBatis的.xml文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.gnayey.mapper.SysUserInfoMapper">
<resultMap id="sysUserInfoDo" type="com.gnayey.entity.SysUserInfoDo">
<id column="ID" property="id" jdbcType="VARCHAR" />
<result column="LOGINNAME" property="loginName" jdbcType="VARCHAR" />
<result column="USERNAME" property="userName" jdbcType="VARCHAR" />
</resultMap>
<sql id="Base_List" >
ID, LOGINNAME, USERNAME
</sql>
<select id="selectByLoginNameAndPassword" resultMap="sysUserInfoDo" >
SELECT
<include refid="Base_List" />
FROM sys_userInfo
WHERE LOGINNAME = #{loginName}
AND PASSWORD= #{password}
</select>
</mapper>
下面是我们的Controller类，代码如下
package com.gnayey.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.gnayey.common.request.vo.GnayeyUserLoginResVo;
import com.gnayey.common.response.vo.ResponseData;
import com.gnayey.common.util.value.SystemCodeConstant;
import com.gnayey.service.GnayeyLoginService;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
@Controller
@RequestMapping("/v1/login")
public class GnayeySysUserLoginController {
@Autowired
private GnayeyLoginService gnayeyLoginService;
@ApiOperation(value = "用户登陆", notes = "注意事项")
@ApiImplicitParams({
@ApiImplicitParam(name = "loginName", value = "登录名", required = true, paramType = "query", example = ""),
@ApiImplicitParam(name = "password", value = "登陆密码", required = true, paramType = "query", example = "")
})
@RequestMapping(value="/userLogin",method=RequestMethod.POST)
@ResponseBody
public ResponseData userLogin(@RequestParam(value="loginName") String loginName, @RequestParam(value="password") String password) {
GnayeyUserLoginResVo response = gnayeyLoginService.userLogion(loginName, password);
if (response != null) {
return new ResponseData(SystemCodeConstant.RIGHT_CODE, response, "请求成功");
}else{
return new ResponseData(SystemCodeConstant.ERROR_CODE, response, "请求失败");
}
}
}
下面是登陆业务接口
package com.gnayey.service;
import com.gnayey.common.request.vo.GnayeyUserLoginResVo;
public interface GnayeyLoginService {
/**
* 用户登陆获取个人信息
* @param loginName 用户名
* @return
*/
public GnayeyUserLoginResVo userLogion(String userCode, String password);
/**
* 从redis中获取用户的登陆信息
* @param tocken 用户登陆tocken
* @return
*/
public GnayeyUserLoginResVo getLoginedUserInfoByRedis(String token);
/**
* 用户登出，从redis中删除用户的登陆信息
* @param tocken 用户登陆tocken
* @return
*/
public void processUserLogout(String token);
/**
* 清楚redis中的token数据
* @param tocken 用户登陆tocken
* @return
*/
void extendUserTokenTime(String token);
}
下面是接口的实现，具体业务写在这里面，有详细的注解：
package com.gnayey.service;
import java.util.HashMap;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.gnayey.common.request.vo.GnayeyUserLoginResVo;
import com.gnayey.common.util.Base64Util;
import com.gnayey.common.vo.GnayeyLoginUserInfoTokenVo;
import com.gnayey.entity.SysUserInfoDo;
import com.gnayey.mapper.SysUserInfoMapper;
import com.gnayey.redis.RedisClient;
@Service
public class GnayeyLoginServiceImpl implements GnayeyLoginService {
@Autowired
private SysUserInfoMapper sysUserInfoMapper;
@Override
public GnayeyUserLoginResVo userLogion(String loginName, String password) {
String loginNameB = Base64Util.decodeData(loginName);//登陆名解密
String passwordB = Base64Util.decodeData(password);//登陆密码解密
SysUserInfoDo sysUserInfeoDo = sysUserInfoMapper.selectByLoginNameAndPassword(loginNameB, passwordB);
if(sysUserInfeoDo == null) {
return null;
}
//生成token，并将其写入到redis中，key值为token
return addUserLoginInfoToRedis(sysUserInfeoDo);
}
@Override
public GnayeyUserLoginResVo getLoginedUserInfoByRedis(String token) {
GnayeyUserLoginResVo response = new GnayeyUserLoginResVo();
RedisClient redisClient = new RedisClient();
Map<String, String> redisUserInfo = redisClient.getHash(token);
if(redisUserInfo.size() == 0){
return null;
}
//从redis中可获取到用户的登陆信息
response.setUserId(redisUserInfo.get(GnayeyLoginUserInfoTokenVo.REDIS_KEY_USERID));
response.setToken(token);
response.setLoginName(redisUserInfo.get(GnayeyLoginUserInfoTokenVo.REDIS_KEY_LOGINNAME));
response.setUserName(redisUserInfo.get(GnayeyLoginUserInfoTokenVo.REDIS_KEY_USERNAME));
redisClient.closeResource();//记得每次操作redis最后都必须要执行关闭方法，不然会导致资源占用，系统内存爆满
return response;
}
@Override
public void processUserLogout(String token) {
RedisClient redisClient = new RedisClient();
redisClient.del(token);
redisClient.closeResource();
}
private GnayeyUserLoginResVo addUserLoginInfoToRedis(SysUserInfoDo sysUserInfeoDo) {
//生成token
String token = java.util.UUID.randomUUID().toString();
//将token写入到redis中，key值为token
RedisClient redisClient = new RedisClient();
//保存至redis的用户数据
Map<String, String> hash = new HashMap<String, String>();
hash.put(GnayeyLoginUserInfoTokenVo.REDIS_KEY_TOKEN, token);
hash.put(GnayeyLoginUserInfoTokenVo.REDIS_KEY_USERID, sysUserInfeoDo.getId() == null ? "":sysUserInfeoDo.getId());
hash.put(GnayeyLoginUserInfoTokenVo.REDIS_KEY_LOGINNAME, sysUserInfeoDo.getLoginName() == null ? "":sysUserInfeoDo.getLoginName());
hash.put(GnayeyLoginUserInfoTokenVo.REDIS_KEY_USERNAME, sysUserInfeoDo.getUserName() == null ? "":sysUserInfeoDo.getUserName());
//将数据保存至redis数据库并设置失效时间
redisClient.setHashAndTime(token, hash, 36000);
redisClient.closeResource();
//返回给前端的用户数据
GnayeyUserLoginResVo responseVo = new GnayeyUserLoginResVo();
responseVo.setToken(token);
responseVo.setUserId(sysUserInfeoDo.getId());
responseVo.setLoginName(sysUserInfeoDo.getLoginName());
responseVo.setUserName(sysUserInfeoDo.getUserName());
return responseVo;
}
@Override
public void extendUserTokenTime(String token) {
//延长token时间
RedisClient redisClient = new RedisClient();
Map<String, String> redisUserInfo = redisClient.getHash(token);
redisClient.setHashAndTime(token, redisUserInfo, 36000);
redisClient.closeResource();
}
}
到这里，一个登陆的接口就完成了，其中包含了Controller交互层，Sercive业务层，Dao持久层，下来启动程序登陆swagger进行测试：
这是启动成功后显示的端口：
接下来，打开浏览器输入地址：localhost:8099/swagger-ui.html
注意，项目中用到了Base64加密，所以在swagger测试输入用户名和密码时要进行加密
base64加密解密链接：
http://tool.oschina.net/encrypt?type=3
然后点击按钮Try it out! 进行访问，结果如下：返回信息，成功
到这里就完成了用户登录接口。全部内容已经写完。
总结SpringBoot能够快速的创建一个Spring项目，并通过注解的方式实现快速编程，易上手。同时也可以结合很多插件等功能进行业务实现，提高开发效率。
此次内容没有描述SpringBoot的全局异常捕获和事务，后面我会继续发文。
