IDEA創建spring加struts2項目


選擇spring和struts,注意版本,不同的struts版本,過濾器的位置不一樣

選擇存放位置,並點擊完成創建項目,在創建過程中會自動下載相關jar

初始化完成后的目錄結構為

修復生成的web.xml文件

1.檢查生成的struts2過濾器和選擇的版本是否一致(現在我的是不匹配的需要修改StrutsPrepareAndExecuteFilter的位置)

2.spring的監聽器ContextLoaderListener,因為沒有生成spring-web-4.3.18.RELEASE.jar,所有要下載spring-web-4.3.18.RELEASE.jar,spring框架下載地址https://repo.spring.io/release/org/springframework/spring/

新的web.xml文件為:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <display-name>struts2</display-name>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <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>
</web-app>

現在生成的路徑還沒還沒有生成lib里面的jar包,配置IDEA生成路徑

在src目錄里新建一個處理請求的action,取名叫LoginAction.java

import com.opensymphony.xwork2.ActionSupport;

/**
 * @author mx
 * @description: TODO
 * @date 2019-06-26 10:43
 */
public class LoginAction extends ActionSupport {

    private String username;

    private String password;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }


    @Override
    public String execute() throws Exception {
        if (username.equals("admin") && password.equals("123456")) {
            return SUCCESS;
        } else {
            return LOGIN;
        }

    }
}

增加sping容器默認的配置文件(也可以指定文件名,這里就直接使用默認的文件名)applicationContext.xml,在里面注入創建的action

<?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="userClass" class="LoginAction" scope="prototype"/>
    
</beans>

在struts.xml配置struts2的映射關系

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>
    <package name="default" namespace="/" extends="struts-default">
        <action name="Login" class="LoginAction">
            <result name="success">/WEB-INF/jsp/success.jsp</result>
            <result name="login">/index.jsp</result>
        </action>
    </package>
</struts>

在WEB-INF目錄下面新建jsp目錄,然后在創建success.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>${username}登錄成功</title>
</head>
<body>
<h1>登錄成功!</h1>
</body>
</html>

修改index.jsp文件

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
  <title>用戶登錄</title>
</head>
<body>
<h1>用戶登錄</h1>
<form action="Login.action" method="post">
  <table>
    <tr>
      <td>用戶名:</td>
      <td><input type="text" name="username"></td>
    </tr>
    <tr>
      <td>密碼:</td>
      <td><input type="password" name="password"></td>
    </tr>
    <tr>
      <td colspan="2" style="text-align: center"><input type="submit" value="登錄"></td>
    </tr>
  </table>
</form>
</body>
</html>

 本來以為在這點就配置完成了,然后配置tomcat運行項目:

結果出現錯誤:

ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...
ERROR Dispatcher Dispatcher initialization failed

    at com.opensymphony.xwork2.config.impl.DefaultConfiguration.reloadContainer(DefaultConfiguration.java:162)

 然后查閱資料,有說,添加classpath下的目錄添加一個log4j2.xml,有說映入log4j-core包的,但是最后都沒有解決,最新想是不是自動stuts2包的問題,就去官網https://struts.apache.org/download.cgi下載最新的試試,下載文件

先刪除原來structs2 的jar

解壓下載的文件,引入新的jar

然后在運行tomcat得到正確的頁面

輸入正確的用戶名和密碼后,跳轉
