实现多个ConstraintValidator及其优先级(由请求端点启用/禁用)

@Target({ElementType.FIELD, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = CustomValidator.class)
public @interface CustomConstraint {
    String message() default "Invalid value";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
}

public class CustomValidator implements ConstraintValidator<CustomConstraint, Object> {
    @Override
    public void initialize(CustomConstraint constraintAnnotation) {
        // 初始化方法，可以在这里获取注解中的参数
    }

    @Override
    public boolean isValid(Object value, ConstraintValidatorContext context) {
        // 验证逻辑，根据具体需求编写验证规则
        return true; // 返回true表示验证通过，返回false表示验证失败
    }
}

@GroupSequence({FirstGroup.class, SecondGroup.class})
public interface ValidationSequence {
}

public class MyEntity {
    @CustomConstraint(groups = FirstGroup.class)
    private String field1;

    @CustomConstraint(groups = SecondGroup.class)
    private String field2;

    // 省略其他字段和方法
}

@RestController
@Validated
public class MyController {
    @PostMapping("/endpoint")
    public ResponseEntity<?> handleRequest(
            @Validated(FirstGroup.class) @RequestBody MyEntity entity1,
            @Validated(SecondGroup.class) @RequestBody MyEntity entity2) {
        // 处理请求的逻辑
        return ResponseEntity.ok().build();
    }
}
