spring整合strus2的Hellowworld
|
比较笨，看了三遍才能理解敲对并正确运行： step： 1、建立web工程（?Dynamic Web project）一定要勾上创建web.xml 2、导入jar包 这个就比较坑了，我查了有半个小时才查出来，我为啥一运行就报错404找不到资源(后来发现是因为WEB-INF/lib下没有引入依赖jar) jar分两个位置引入： 1)、正常位置引入lib： antlr-2.7.7.jar 2）、在WEB-INF/lib下加入jar com.springsource.net.sf.cglib-2.2.0.jar 3、创建实体Hellow package com.strus2.entity; public class Hellow { private String str; void setStr(String str) { this.str = str; } hellow(){ System.out.println("hellow,"+str); } } 创建bean文件： <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> bean id="hellow" class="com.strus2.entity.Hellow"> property name="str" value="world!!"></property</bean> beans> ? 4、创建监听类 com.strus2.listener; import javax.servlet.ServletContext; javax.servlet.ServletContextEvent; javax.servlet.ServletContextListener; javax.servlet.annotation.WebListener; org.springframework.context.ApplicationContext; org.springframework.context.support.ClassPathXmlApplicationContext; /** * Application Lifecycle Listener implementation class Struslistener * */ @WebListener class Struslistener implements ServletContextListener { * Default constructor. */ public Struslistener() { // TODO Auto-generated constructor stub } * @see ServletContextListener#contextInitialized(ServletContextEvent) contextInitialized(ServletContextEvent arg0) { TODO Auto-generated method stub 获取Spring配置文件名称 ServletContext servletContext = arg0.getServletContext(); String config = servletContext.getInitParameter("configLocation"); 闯将ioc容器，将ioc容器放到ServletContext属性中 ApplicationContext ctx=new ClassPathXmlApplicationContext(config); servletContext.setAttribute("ApplicationContext",ctx); } ServletContextListener#contextDestroyed(ServletContextEvent) contextDestroyed(ServletContextEvent arg0) { TODO Auto-generated method stub } } 5、创建测试Servlet 只勾选doget复选框 com.strus2.test; java.io.IOException; javax.servlet.ServletException; javax.servlet.annotation.WebServlet; javax.servlet.http.HttpServlet; javax.servlet.http.HttpServletRequest; javax.servlet.http.HttpServletResponse; org.springframework.context.ApplicationContext; com.strus2.entity.Hellow; * Servlet implementation class TestServlet @WebServlet("/TestServlet") class TestServlet extends HttpServlet { private static final long serialVersionUID = 1L; HttpServlet#doGet(HttpServletRequest request,HttpServletResponse response) protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException { 从Servletcontent域对象中，获取ioc容器 ServletContext servletContext = getServletContext(); ApplicationContext ctx = (ApplicationContext) servletContext.getAttribute("ApplicationContext" 获取所需要的bean Hellow hellow = ctx.getBean(Hellow.); hellow.hellow(); response.getWriter().append("Served at: ").append(request.getContextPath()); } } 创建inde.jsp <%@ page language="java contentTypetext/html; charset=ISO-8859-1 pageEncodingISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> htmlheadmeta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"title>Insert title herebodya href="TestServlet">TestServleta> 6、web.xml web-app xmlns:xsi 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>strus2-demowelcome-file-listwelcome-file>index.html>index.htm>index.jsp>default.html>default.htm>default.jspcontext-paramparam-name>configLocationparam-value>classpath:bean.xml<!-- <listener> <listener-class>com.strus2.listener.Struslistener</listener-class> </listener> --> web-app> ? 注意：运行测试，需要选中整个工程，run-onserver-选择Tomcat7.0 server，即可
? ?点击TestServlet 效果如下：
