• SSH框架搭建


    一。加入struts2
    1.在pom.xml中加入struts2的依赖
      <dependency>
        <groupId>org.apache.struts</groupId>
        <artifactId>struts2-core</artifactId>
        <version>2.5.13</version>
      </dependency>
    2.在web.xml中加入过滤器
      <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
      </filter>
      <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>

    二。加入spring框架,整合spring+struts2
    1.加入spring的依赖,和struts与spring整合的依赖
      <!-- Spring -->
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.1.9.RELEASE</version>
      </dependency>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.1.9.RELEASE</version>
      </dependency>
      <dependency>
        <groupId>org.apache.struts</groupId>
        <artifactId>struts2-spring-plugin</artifactId>
        <version>2.5.13</version>
      </dependency>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-orm</artifactId>
        <version>4.1.9.RELEASE</version>
      </dependency>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>
        <version>4.1.9.RELEASE</version>
      </dependency>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>4.1.9.RELEASE</version>
      </dependency>
      <!-- hibernate -->
      <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.3.5.Final</version>
      </dependency>
      <!-- 数据库连接池jar -->
      <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-dbcp2</artifactId>
        <version>2.1.1</version>
      </dependency>
    2.在web.xml中加入spring监听,以及告诉监听spring的配置文件
      <!-- 创建Spring的监听器 -->
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      <!-- Spring的监听器可以通过这个上下文参数来获取application.xml文件的位置 -->
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:application.xml</param-value>
      </context-param>

      <!-- Spring中提供了 org.springframework.orm.hibernate4.support.OpenSessionInViewFilter
      这个类来完成OpenSessionInViewer的操作 -->
      <!-- 这个过滤器是配合hibernate中级联操作的延迟加载来使用的,一旦用了这个过滤器,就必须使用spring的事务管理 -->
      <filter>
        <filter-name>openSessionInViewerFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
      </filter>

      <filter-mapping>
        <filter-name>openSessionInViewerFilter</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>
    3.struts.xml文件修改
      <struts>

        <package>
          <constant name="struts.enable.DynamicMethodInvocation" value="true" />
          <!-- //2.5的版本后动态访问url必须打开 -->
          <constant name="struts.objectFactory" value="spring" />
          <!-- //此处说明action由spring管理 -->
          <package name="my" namespace="/" extends="struts-default">
          <global-allowed-methods>regex:.*</global-allowed-methods>
          <!-- //2.5版本后访问非execute方法要加入该配置 -->
          <action name="*_*" class="{1}Action" method="{2}">
            <result name="success">${successURL}</result>
            <result name="input">${inputURL}</result>
          </action>
        </package>
      </struts>

    4.appliaction.xml也就是spring核心配置文件

    5.各层用注解完成依赖注入
      @Repository:DAO层的注解申明
      @Service:业务层注解
      @Controller:控制层注解 @Controller("userAction")此处的名字要和struts.xml中Action的class属性一致

    实例:整合ssh,并完成前台发送请求后台,后台返回数据到前台的过程

    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    
    import com.opensymphony.xwork2.ActionContext;
    import com.opensymphony.xwork2.spring.interceptor.ActionAutowiringInterceptor;
    import com.pojo.Student;

    @Controller("stuAction")
    public class StudentAction {
    
        @Autowired
        IStudentService stuSer ;
    
        String successURL;//跳转到成功结果的url路径

    Map req
    = (Map) ActionContext.getContext().get("request"); req.put("list", list);
    successURL
    ="/jsp/student.jsp";
    return "success"; } }

      其他层代码省略,另外BaseDao中方法替换

        @Override
        public Session getsSession(){
            //如果使用spring来管理事务,一定要用getCurrentSession()来获取session
            return sessionFactory.getCurrentSession();
        }
