本章讲解Struts2整合Spring

方法

1.概念

首先，我们知道SpringMVC框架的简洁性和兼容性都要比Struts2要好的多，这也是为什么我只讲解了这么一点Struts2的内容，还有相当一部分的Struts2的内容我没有涉及到，还请大家注意！我们日后接触的还是SpringMVC居多！

2.准备工作

如果需要Struts2整合Spring，那么和使用注解一样，我们需要引入一个插件的jar包

2.配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <!-- 配置Struts2分发器 -->
    <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>*.action</url-pattern>
    </filter-mapping>
    <!-- 加载Spring配置文件 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- 配置欢迎页 -->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

具体的spring配置文件的内容请参照spring章节进行学习！

3.SMS登录功能的实现

配置登录的Action

package cn.edu.ccut.action;


import cn.edu.ccut.service.StudentService;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

@Controller
@ParentPackage("struts-default")
@Namespace("/")
public class LoginAction extends ActionSupport {
    private String username;
    private String password;
    @Autowired
    private StudentService studentService;

    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;
    }

    @Action(value = "login", results = {
            @Result(name = "success", location = "/admin/list/welcome.jsp"),
            @Result(name = "error", location = "/admin/login/login.jsp")})
    public String login(){
        boolean flag = studentService.login(username, password);
        if (flag) {
            return "success";
        }else {
            return "error";
        }
    }


}

如此同样可以实现我们之前SMS的登录操作，但是大家觉得和SpringMVC比哪个简单啊！

很明显，Struts2居于下风，SpringMVC更胜一筹！！！
