如何搭建 SSM 框架集成环境？

SSM 框架集成环境搭建方式

• jar 包依赖添加
• web.xml 文件配置
• Springmvc 配置文件 servlet-context.xml 添加
• Spring.xml 配置

案例实操

1.jar 包依赖添加（原有基础上继续添加 springmvc 相关依赖 jar 包及对应 jetty 插件） 修改 pom.xml 文件

扩展

Helloworld 编写

搭建好SSM集成框架，Hellocontroller 的编写就变得非常简单

@Controller 

public class HelloController { 

    /** 

    * 注入 service 层 userService 接口 

    */ 

    @Autowired 

    private UserService userService; 

    @RequestMapping("/hello") 

    public ModelAndView hello(){ 

        ModelAndView mv=new ModelAndView(); 

        /** 

        * 调用 service 层查询方法 

        */ 

        User user=userService.queryUserById(7); 

        System.out.println(user); 

        mv.addObject("user", user); 

        mv.setViewName("hello"); 

        return mv; 

    } 

} 

视图页面部分代码接收结果显示:

<body> 
 
	欢迎你，${user.userName} 

</body> 

启动 jetty 服务器，访问地址: http://localhost:8080/ssm/hello.do
