关于java:如何搭建-SSM-框架集成环境

SSM 框架集成环境搭建形式

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

案例实操

1.jar 包依赖增加（原有根底上持续增加 springmvc 相干依赖 jar 包及对应 jetty 插件）批改 pom.xml 文件

扩大

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;
​
}
​
}

视图页面局部代码接管结果显示:

<body>

欢送你，${user.userName}
​
</body>

启动 jetty 服务器，拜访地址: http://localhost:8080/ssm/hello.do
