- 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; } }
访问
结果
- SpringMVC配置
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。
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> <!--configure the setting of springmvcDispatcherServlet and configure the mapping--> <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:springmvc-servlet.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>
springmvc-servlet.xml
<?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" 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-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"> <!-- scan the package and the sub package --> <context:component-scan base-package="mvc"/> <!-- don't handle the static resource --> <mvc:default-servlet-handler /> <!-- if you use annotation you must configure following setting --> <mvc:annotation-driven /> <!-- configure the InternalResourceViewResolver --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver"> <!-- 前缀 --> <property name="prefix" value="/WEB-INF/jsp/" /> <!-- 后缀 --> <property name="suffix" value=".jsp" /> </bean> </beans>
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。
