Spring+Struts2整合

1，整合Struts2
     a)导入struts的jar包
         struts2-core-2.1.6.jar   xwork-2.1.2.jar ognl-2.6.11.jar    freemarker-2.3.13.jar commons-logging-1.1.jar commons-fileupload-1.2.1.jar
    b)将struts.xml文件拷贝到src目录下
    c)在web.xml里配置struts的核心过滤器

<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>

2，整个Spring
      a)导入Spring的jar包 spring.jar commons-logging.jar
      b)将applicationContext.xml文件拷贝到WEB-INF目录下
      c)在web.xml里配置spring的易做图


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

       d)添加spring与struts2整合的插件 struts2-spring-plugin-2.1.6.jar

3，编写代码测试
登录页面login.jsp

<body>
   <form action="login" method="post">
       USERNAME:<input type="text" name="username" /><br>
       PASSWORD:<input type="password" name="password" /><br>
       <input type="submit" value="登录">
   </form>
</body>

登录成功页面 success.jsp

<body>
登录成功!
</body>

LoginDao业务接口

package com.itmyhome.actioin;

inte易做图ce LoginDao {
public boolean login(String username,String password);
}

LoginDaoImpl业务接口实现

package com.itmyhome.actioin;

public class LoginDaoImpl implements LoginDao {

    public boolean login(String username, String password) {
        // TODO Auto-generated method stub
        if("zhangsan".equals(username)&&"123".equals(password)){
            return true;
        }else{
            return false;
        }
    }

}

LoginAction

package com.itmyhome.actioin;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {
    private String username;
    private String password;
    private LoginDao loginDao; //此DAO交给spring来处理
    public String execute(){

        if(loginDao.login(username, password)){
            return "success";
        }else{
            return "input";
        }
    }

    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;
    }

    public LoginDao getLoginDao() {
        return loginDao;
    }

    public void setLoginDao(LoginDao loginDao) {
        this.loginDao = loginDao;
    }

}

struts.xml配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

    <package name="default" namespace="/" extends="struts-default">
        <action name="login" class="com.itmyhome.actioin.LoginAction">
           <result name="success">/success.jsp</result>
           <result name="input">/login.jsp</result>
        </action>
    </package>

    

</struts>

applicationContext.xml配置文件

<bean id="loginDao" class="com.itmyhome.actioin.LoginDaoImpl" />


<bean id="loginAction" class="com.itmyhome.actioin.LoginAction">
<property name="loginDao" ref="loginDao" />
</bean>

部署，启动tomcat 输入"zhangsan","123" 跳转到success.jsp 整合成功
