spring boot security學習
- 自定以securityconfig
package com.cai.config; import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; import java.beans.Encoder; /** * @BelongsProject:IntelliJ IDEA * @Package:com.cai.config * @Author:superman * @CreateTime:2021--01--17 11:04 * @Description: */ //AOP橫切 @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { //授權 @Override protected void configure(HttpSecurity http) throws Exception { //首頁所有人可以通路,但是裡面的功能頁隻有對應有權限的人才可以通路 //請求授權的規則 http.authorizeRequests() .antMatchers("/").permitAll() .antMatchers("/level1/**").hasRole("vip1") .antMatchers("/level2/**").hasRole("vip2") .antMatchers("/level3/**").hasRole("vip3"); //沒有權限預設回到登入頁面,需要開啟登入的頁面 http.formLogin().loginPage("/toLogin"); //防止網站攻擊：get不安全，post //關閉csrf攻擊功能 http.csrf().disable(); //登出,開啟了登出功能,跳到首頁 http.logout().logoutSuccessUrl("/"); //開啟記住我功能 cookie,預設儲存兩周，自定義接受前端的參數 http.rememberMe().rememberMeParameter("remember"); } //認證，springboot2.1.x 可以直接使用 //如果出現500說明版本過高，需要密碼加密：PasswordEncoder //在spring security5.0+ 新增了很多的加密方式 @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { //這些資料正常應該從資料庫裡面拿 auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()) .withUser("admin").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3") .and() .withUser("caiji").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3") .and() .withUser("guest").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1"); } } - 建立routercontroller
package com.cai.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; /** * @BelongsProject:IntelliJ IDEA * @Package:com.cai.controller * @Author:superman * @CreateTime:2021--01--17 10:48 * @Description: */ @Controller public class RouterController { @RequestMapping({"/","/index"}) public String index(){ return "index"; } @RequestMapping("/toLogin") public String toLogin(){ return "views/login"; } @RequestMapping("/level1/{id}") public String level1(@PathVariable("id") int id){ return "views/level1/"+id; } @RequestMapping("/level2/{id}") public String level2(@PathVariable("id") int id){ return "views/level2/"+id; } @RequestMapping("/level3/{id}") public String level3(@PathVariable("id") int id){ return "views/level3/"+id; } } - 權限控制頁面
