建構maven的SSH項目

每次要部署SSH項目都感覺有一點生疏，于是打算寫一篇部落格整理一下，希望把這些簡單的東西熟記于心。

首先我們先用eclipse建立一個maven的web項目：

項目名稱我取為weibo，包的目錄結構為com.alphaking,finish:

我簡單的建立一下的包的目錄結構：

接下來開始配置ssh。首先配置一下spring+hibernate，在src/main/resources 下建立applicationContext.xml檔案：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd">
    <!-- 使用注解 -->
    <context:annotation-config />
    <context:component-scan base-package="com.alphaking.*" />
    <!-- 映射jdbc配置檔案(我習慣将hibernate連接配接屬性寫在同目錄下的一個jdbc.properties檔案裡,友善修改) -->
    <bean
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <value>classpath:jdbc.properties</value>
        </property>
    </bean>
    <!-- 配置datasource -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="${jdbc.driverClassName}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
    </bean>
    <!-- 配置sessionFactory-->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="packagesToScan">
            <list >
               <value>com.alphaking.model</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
    </bean>
    <!-- 在你執行方法之前自動開啟事務，結束關閉事務。減少代碼量及錯誤幾率 -->
    <bean id="txManager"
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    <!-- 它是某個連接配接點所采用的處理邏輯，也就是向連接配接點注入的代碼 -->
    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
        <!-- Pointcut裡方法的事務處理 -->
            <tx:method name="*" isolation="DEFAULT" propagation="REQUIRED" />
        </tx:attributes>
    </tx:advice>
    <!-- <tx:annotation-driven transaction-manager="txManager"/> 注解@Transactional-->
    <aop:config>
    <!-- Pointcut 是指那些方法需要被執行"AOP",是由"Pointcut Expression"來描述的. 
    它是程式中需要注入Advice 的位置的集合，指明Advice要在什麼樣的條件下才能被觸發。
    -->
        <aop:pointcut id="bussinessService" expression="execution(public * com.alphaking.service..*.*(..))" />

        <aop:advisor pointcut-ref="bussinessService" advice-ref="txAdvice" />
    </aop:config>

</beans>
           

然後在配置spring-mvc,xml檔案如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
       http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
       http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
       http://www.springframework.org/schema/mvc 
       http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context-4.1.xsd
       ">
    <!-- 采用注解的方式裝配bean -->
    <context:annotation-config />   
    <!--啟動Spring MVC注解 -->
    <mvc:annotation-driven />
    <!-- 采用元件掃描方式注冊bean -->
    <context:component-scan base-package="com.alphaking.*" />
    <!-- 對模型controller到視圖view 名稱的解析，在請求時模型視圖名稱添加前字尾 -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver"
        p:prefix="/jsp/" p:suffix=".jsp" />
    <!-- 配置檔案上傳 -->
    <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 預設編碼 -->
        <property name="defaultEncoding" value="utf-8" />
        <!-- 檔案大小最大值 -->
        <property name="maxUploadSize" value="10485760000" />
        <!-- 記憶體中的最大值 -->
        <property name="maxInMemorySize" value="40960" />
    </bean>


</beans>
           

再修改一下web.xml:

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>weibo</display-name>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <!-- spring啟動 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
    <servlet>
    <servlet-name>SpringMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
    <servlet-mapping>
    <servlet-name>SpringMVC</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>
           

最後在maven的pom.xml檔案裡導入依賴：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
