struts2整合spring2.5.6

来源：互联网发布：php语言入门编辑：程序博客网时间：2024/06/06 01:39

一、struts2.0的包可以去http://struts.apache.org/downloads.html下载,将struts2.0中的包(commons-logging-1.0.4.jar,freemarker-2.3.10.jar,ognl-2.6.11.jar,struts2-core-2.1.0.jar,xwork-2.1.0.jar)和spring2.5.6中的包(spring.jar)以及struts2-spring-plugin-2.0.14.jar包(用于struts跟spring整合)放在lib目录下

二、修改web.xml文件,配置一个过滤器

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

三、在web.xml中配置一个监听器

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

四、在src目录下新建struts.xml文件，文件内容如下：

<?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">

　　</package>

</struts>

五、创建LoginAction类、LoginService接口、LoginServiceImpl类、User类。

public class LoginAction extends ActionSupport implements ModelDriven<User> {

/**
*
*/
private static final long serialVersionUID = 1L;

private LoginService<User> loginService;

private User user;

public String execute() throws Exception {

  if(loginService.checkUser(user))
   return SUCCESS;
  else
   return INPUT;
}

public LoginService<User> getLoginService() {
return loginService;
}

public void setLoginService(LoginService<User> loginService) {
this.loginService = loginService;
}

public User getUser() {
return user;
}

public void setUser(User user) {
this.user = user;
}

public User getModel() {

return user;
}

}

public interface LoginService<T> {

public boolean checkUser(User user);

public boolean checkUser(String name,String password);

}

public class User implements Serializable {

/**
*
*/
private static final long serialVersionUID = 1L;

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;
}

}

public class LoginServiceImpl<T> implements LoginService<T> {

public boolean checkUser(User user) {

  if(user.getUsername().trim().equals("tang")&&user.getPassword().trim().equals("1234"))
   return true;
  else
   return false;

}

public boolean checkUser(String name, String password) {

  if(name.equals("tang")&&password.equals("1234"))
   return true;
  else
   return false;
}

}

六、在WEB-INF目录下创建applicationContext.xml文件，并在其中配置，内容如下：

<?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:tx="http://www.springframework.org/schema/tx"
  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

</beans>

七、创建login.jsp，success.jsp如下

<body>
用户名：${requestScope.user.username }<br>
密码：${requestScope.user.password }
</body>

八、配置struts.xml文件，内容如下：

<struts>
<package name="struts2" extends="struts-default" >
    <action name="LoginAction" class="loginAction" >
   <result name="success" >success.jsp</result>
   <result name="input" >login.jsp</result>
  </action>
</package>
</struts>

九、将其发布到tomcat，起动tomcat服务器，打开浏览器输入http://localhost:8080，输入用户和密码进行测试。
