spv简单的 Spring 参数验证库

springmvc springboot 简单轻量好用的参数验证。支持基本类型查参数验证。支持自定义注解的参数验证。使用简单方便。

使用4步配置

1、导入jar

        <dependency>
            <groupId>com.github.fashionbrot</groupId>
            <artifactId>mars-validated</artifactId>
            <version>1.0.0</version>
        </dependency>

2、使用注解

2.1 springboot 配置

@SpringBootApplication
@EnableValidatedConfig(fileName = "valid_zh_CN")
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

2.2 spring配置

@Component
@Configuration
@EnableValidatedConfig(fileName = "valid_zh_CN")
public class Config {


}

3、使用 @Validated 开启接口验证 @Email验证邮箱格式

@Controller
public class DemoController {

    @Autowired
    private TestService testService;
    

    @RequestMapping("/emailCheck")
    @ResponseBody
    @Validated //注意此处
    public String demo(@Email String abc,){
        return testService.test(abc);
    }

}   
@Controller
public class DemoController {

    @Autowired
    private TestService testService;
    
    
    @RequestMapping("/idcardCheck")
    @ResponseBody
    @Validated
    public String demo(IdCardModel idCardModel){
        return testService.test("ac");
    }
    
    @RequestMapping("/idcardCheck2")
    @ResponseBody
    public String demo2(IdCardModel idCardModel){
        return testService.test2("ac");
    }


}

**此处支持多继承验证*** 

public class IdCardModel extends BaseModel{

    @IdCard
    private String idCardModel;

    public String getIdCardModel() {
        return idCardModel;
    }

    public void setIdCardModel(String idCardModel) {
        this.idCardModel = idCardModel;
    }

}

@Service
public class TestService{

    @Validated
    public void test2(@IdCard String abc){

    }

}

4、自定义实现全局异常处理

拦截 com.fashion.spv.validated.exception.ValidatedException

@RestControllerAdvice
public class GlobalExceptionHandler {

     
    @ExceptionHandler(ValidatedException.class)
    @ResponseStatus(HttpStatus.OK)
    public RespMessage ValidationException(ValidatedException e){

        return new RespMessage(-100,e.getMsg());
    }

}

validated 参数验证

使用环境

spring4.0 及以上
jdk1.8 及以上

支持自定义注解 如下：

1、实现  ConstraintValidator 此接口
2、自定义注解如下：  CustomConstraintValidator.class,CustomConstraintValidator2.class 实现类可多个，至少有一个

    @Documented
    @Target({ElementType.FIELD,  ElementType.PARAMETER})
    @Retention(RetentionPolicy.RUNTIME)
    @Constraint(validatedBy = {CustomConstraintValidator.class,CustomConstraintValidator2.class})
    public @interface Custom {
    
        String msg() default "com.spv.valid.Custom.msg";
    
        int min();
    }


3、代码实现



public class CustomConstraintValidator implements ConstraintValidator<Custom,String> {

    @Override
    public boolean isValid(Custom custom,String var1) {
        /**
         * 自定义方法
         */
        int min=custom.min();
        /**
         * value
         */
        System.out.println(var1);
        /**
         * return true 则验证成功 false 验证失败
          */
        return true;
    }
}
