SpringBoot

如果我们不统一处理异常，经常会在controller曾有大量的异常处理代码，比如：

@Slf4j
@Api(value = "User Interfaces", tags = "User Interfaces")
@RestController
@RequestMapping("/user")
public class UserController {

    /**
     * http://localhost:8080/user/add .
     *
     * @param userParam user param
     * @return user
     */
    @ApiOperation("Add User")
    @ApiImplicitParam(name = "userParam", type = "body", dataTypeClass = UserParam.class, required = true)
    @PostMapping("add")
    public ResponseEntity<String> add(@Valid @RequestBody UserParam userParam) {
        // 每个接口充斥着大量的异常处理
        try {
            // do something
        } catch(Exception e) {
            return ResponseEntity.fail("error");
        }
        return ResponseEntity.ok("success");
    }
}
