SSM整合-Spring整合SpringMVC 06

1、在web.xml配置spring

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext.xml</param-value>
  </context-param>
  <!--启动服务器时，通过监听器加载spring运行环境-->
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
  <!--用于解决中文乱码-->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <!--拦截-->
  <servlet>
    <servlet-name>DispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath*:spring-mvc.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

2、

@RestController
@RequestMapping("/user")
public class UserController {

    @Autowired
    private UserService userService;

    @PostMapping
    public boolean save(User user) {
        return userService.save(user);

    }

    @PutMapping
    public boolean update(User user) {
        return userService.update(user);
    }

    @DeleteMapping("/{uuid}")
    public boolean delete(@PathVariable int uuid) {
        return userService.delete(uuid);
    }

    @GetMapping("/{uuid}")
    public User get(@PathVariable int uuid) {
        return userService.get(uuid);
    }

    @GetMapping("/{page}/{size}")
    public PageInfo<User> getAll(@PathVariable int page, @PathVariable int size) {
        return userService.getAll(page, size);
    }

    @PostMapping("/login")//为了和save的请求做区分
    public User login(String userName, String password) {
        return userService.login(userName, password);
    }
}
