How to build SSM framework integrated environment

  • Jar package dependency adding
  • Web.xml file configuration
  • Add spring MVC configuration file servlet-context.xml
  • Spring.xml configuration

Case practice

1. Add jar package dependency (continue to add spring MVC dependent jar package and corresponding jetty plug-in) to modify pom.xml file

Written by HelloWorld

After setting up the SSM integration framework, the writing of hellocontroller becomes very simple

@Controller

public class HelloController {

/**

  • Injection of service layer userservice interface


*/

@Autowired

private UserService userService;

@RequestMapping(“/hello”)

public ModelAndView hello(){

ModelAndView mv=new ModelAndView();

/**

  • Call the service layer query method


*/

User user=userService.queryUserById(7);

System.out.println(user);

mv.addObject(“user”, user);

mv.setViewName(“hello”);

return mv;

}

}

The code receiving results of the view page are as follows:

<body>

Welcome, ${user. Username}

</body>

Start jetty server, access address:http://localhost:8080/ssm/hello.do
