配置struts2+spring,springmvc

时间:2022-07-14 21:30:14
  • Struts2+Spring整合

    一.spring负责注入,struts2负责它自己的工作。这样不是很符合spring作为ioc容器的全部功能,不推荐。

    二.spring负责全部bean和struts2的action的生成。作为ioc容易的最大共用。

    所需要jar包

      配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>Struts2AndSpring</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <!-- 初始化 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- 配置spring监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
   <filter>
    <filter-name>struts2</filter-name>
    <filter-class>
          org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
      </filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

    关键点:配置struts2核心过滤器;配置spring工厂的监听器;把applicationContext.xml的路径指明。

    配置struts2.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

    <constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <constant name="struts.devMode" value="true" />
    <constant name="struts.i18n.encoding" value="UTF-8"/>
    <!--整合spring-->
    <constant name="struts.objectFactory" value="spring" />
    <!-- Add packages here -->

    <package name="default" namespace="/" extends="struts-default">
        <!-- 测试action-->
        <!-- class对应applicationContext.xml的id,在applicationContext.xml上配置真是路径 -->
        <action name="Hello" class="Hello">
            <result name="success"></result>
        </action>
    </package>

</struts>

    配置applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
    "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
    <bean id="Hello" class="action.TestAction" autowire="byName" scope="prototype">
    </bean>
</beans>

    action例子

package action;

import java.io.IOException;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;
/**
 * 测试action
 * @author MacBook
 *
 */
public class TestAction extends ActionSupport{
    public String execute(){
        System.out.println("执行了!!!");
        try {
            ServletActionContext.getResponse().getWriter().print("hello");
        } catch (IOException e) {
            e.printStackTrace();
        }
        return SUCCESS;
    }
}

    我是新手,网上很多解析这个框架的。这个就集成在spring下载下来的jar包里。

</beans>

配置struts2+spring,springmvc

package mvc;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/mvc")
public class mvcController {
    @RequestMapping("/hello")
    public String hello(){
        System.out.println("hello world");
        return "hello";
    }
}

   注释声明了它是控制器,并且定义了请求映射。

   访问的时候使用/项目名/mvc/hello 访问此方法。
