1、@Validated Basic parameter verification

Entity class

@Data
public class User1Dto {
    
    /** *  user name  */
    @NotBlank(message = " The username cannot be empty ！")
    private String username;
    /** *  Gender  */
    @NotBlank(message = " Gender cannot be empty ！")
    private String gender;
    /** *  Age  */
    @Min(value = 1, message = " Wrong age ！")
    @Max(value = 120, message = " Wrong age ！")
    private int age;
    /** *  Address  */
    @NotBlank(message = " Address cannot be empty ！")
    private String address;
    /** *  mailbox  */
    @Email(message = " Error in mailbox ！")
    private String email;
    /** *  Phone number  */
    @Pattern(regexp = "^(13[0-9]|14[579]|15[0-3,5-9]|16[6]|17[0135678]|18[0-9]|19[89])\\d{8}$",message = " Wrong mobile number ！")
    private String mobile;
}

The control class

@RestController
@RequestMapping("/api/v1")
public class Demo1Controller {
    
 
    @PostMapping("/insert")
    public String validatedDemo1(@Validated @RequestBody Use1Dto use1Dto){
    
        System.out.println(use1Dto);
        return "success";
    }
}

2、@Validated Group parameter verification

First step 、 Define a verification group class , Declare that the four interfaces correspond to different scenario verification

public class ValidationGroups {
    

	public interface Select {
    
	}
	
	public interface Insert {
    
	}
	
    public interface Update {
    
    }
    
    public interface Detail {
    
    }
  
    public interface Delete{
    

    }
}

The second step 、 Add verification rules and verification groups to the specific attributes of the entity class

@Data
public class Person {
    

    @NotNull(message = "personId Not for null",groups = Select.class)
    private Integer personId;
    
    @NotEmpty(message = "name Can't be empty ",groups = Insert.class)
    private String name;
    
    private Integer age;
}

The third step 、 Create queries and new interfaces in the control layer , add to @Validated annotation , Assign groups , Can be more .

    @GetMapping("/select")
    public Object select(@Validated({
    ValidationGroups.Select.class}) Person person) {
    
        return person;
    }

    @GetMapping("/insert")
    public Object insert(@Validated(ValidationGroups.Insert.class) Person person) {
    
        return person;
    }

3、@Validated Nested parameter validation

Entity class

@Data
public class Team1Dto {
    
    /** *  Team name  */
    @NotBlank(message = " Team name cannot be empty ！")
    private String name;
    /** *  Team personnel  */
    @NotNull(message = " Team personnel cannot be empty ！")
    @Valid
    private List<User1Dto> userList;
 
    /** *  Team leader  */
    @NotNull(message = " Team leader cannot be empty ！")
    @Valid
    private User1Dto user;
}

The control class

@RestController
@RequestMapping("/api/v1")
public class Demo1Controller {
    
 
    @PostMapping("/insert")
    public Result validatedDemo1(@Validated @RequestBody Use1Dto use1Dto){
    
        return ResultUtil.success(use1Dto);
    }
 
    @PostMapping("/insert2")
    public Result validatedDemo2(@Validated @RequestBody Team1Dto team1Dto){
    
        return ResultUtil.success(team1Dto);
    }
}
