maven运行struts项目进行测试:
在入门二中已经导入struts的jar包。
此时的pom.xml文件
<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>cn.qlq</groupId> <artifactId>struts</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <build> <!-- 配置了很多插件 --> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.5.1</version> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.3.24</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.9</version> <scope>test</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> </dependencies> </project>
1.创建一个Action
package cn.qlq.Action; import com.opensymphony.xwork2.ActionSupport; public class TestAction extends ActionSupport { private String id; public String getId() { return id; } public void setId(String id) { this.id = id; } @Override public String execute() throws Exception { // TODO Auto-generated method stub System.out.println("这是一个测试！！！！"+id); return super.execute(); } }
2.创建对应的jsp页面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> 这是一个测试！！！！！！！！！！！！ </body> </html>
3.添加struts.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.custom.i18n.resources" value="errors"></constant> <!-- 第一个package命名空间 --> <package name="user" namespace="/" extends="struts-default"> <action name="test" class="cn.qlq.Action.TestAction"> <result>/message.jsp</result> </action> </package> </struts>
4.web.xml中配置struts过滤器
<?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"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <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> <servlet> <description></description> <display-name>Hello</display-name> <servlet-name>Hello</servlet-name> <servlet-class>cn.qlq.servlet.Hello</servlet-class> </servlet> <servlet-mapping> <servlet-name>Hello</servlet-name> <url-pattern>/Hello</url-pattern> </servlet-mapping> </web-app>
5.启动测试:
小结:端口被占用可以关闭启动的项目，
