基于Netty实现的高性能RESTful服务框架
netty-rest-server是基于Netty开发的高性能RESTful框架,提供控制器注解、全局异常控制器、拦截器等功能。
注解名称参考了Spring MVC,编译理解和记忆
- @RestController
- @RequestMapping
- @GetMapping
- @PostMapping
- @DeleteMapping
- @PutMapping
- @PatchMapping
- @JsonResponse
- @RequestParam
- @PathVariable
- @RequestBody
- @UploadFile
- @UrlEncodedForm
- @RequestHeader
//默认为单例,singleton = false表示启用多例。
//@RestController(singleton = false)
@RestController
@RequestMapping("/users")
public class UserController {
@GetMapping("")
@JsonResponse
public ResponseEntity<User> listUser() {
// 查询用户
User user = new User();
user.setId(1);
user.setName("Leo");
user.setAge((short)18);
return ResponseEntity.ok().build(user);
}
@PutMapping("/{id}")
public ResponseEntity<?> putMethod(@PathVariable("id") int id, @RequestBody String body) {
// 更新用户
return ResponseEntity.status(HttpStatus.CREATED).build();
}
@DeleteMapping("/{id}")
public ResponseEntity<?> deleteMethod(@PathVariable int id) {
// 删除用户
return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
}
@PostMapping("")
public ResponseEntity<?> postMethod(@RequestBody String body) {
// 添加用户
JSONObject json = JSONObject.parseObject(body);
User user = new User();
user.setId(json.getIntValue("id"));
user.setName(json.getString("name"));
user.setAge(json.getShortValue("age"));
return ResponseEntity.status(HttpStatus.CREATED).build(user);
}
}

// 添加拦截器,按照添加的顺序执行。
// 跨域拦截器
