在Java后端中POST请求有很多种方法，这里介绍三种方式：

普通方法

@RestController
    @RequestMapping(value = "/user")
    public class UserController {
    
     ......
    /**
    * 直接传入参数
    **/
     @RequestMapping(value = "/save/{name}/{address}",method = RequestMethod.POST)
        public String saveUser(@PathVariable String name,@PathVariable String address ) {
            User user = new User();
            user.setName(name);
            user.setAddress(address);
            userService.saveUser(user);
            return "保存成功";
        }

requestBody传入Json数据，这里Content-Type: application/json

/**
     *客户端需要以Content-Type: application/json来访问
     *
     **/
        @RequestMapping(value = "/save",method = RequestMethod.POST)
        public String saveUser(@RequestBody User user) {
            userService.saveUser(user);
            return "保存成功";
        }

![json][]

requestBody传入Json数据，这里Content-Type: application/x-www-form-urlencoded

/**
    *客户端需要以Content-Type: application/x-www-form-urlencoded来访问
    *
    **/
        @RequestMapping(value = "/save",method = RequestMethod.POST)
        public String saveUser(@RequestBody String name,@RequestBody String address ) {
           User user = new User();
            user.setName(name);
            user.setAddress(address);
            userService.saveUser(user);
            return "保存成功";
        }

![form][]
