Spring Boot ——使用javax.validation进行参数校验

demo1

实体类

public class UserBean {
    @NotBlank(message="用户名不能为空")
    private String userName;

    @NotBlank(message="年龄不能为空")
    @Pattern(regexp="^[0-9]{1,2}$",message="年龄不正确")
    private String age;

    @AssertFalse(message = "必须为false")
    private Boolean isFalse;
    /**
     * 如果是空，则不校验，如果不为空，则校验
     */
    @Pattern(regexp="^[0-9]{4}-[0-9]{2}-[0-9]{2}$",message="出生日期格式不正确")
    private String birthday;
}

测试;

@RestController
@RequestMapping("/vh")
public class ValidatorController {
 
    @RequestMapping("/resign")
    public String resign(@RequestBody @Valid  UserBean user ) {
    	
    	
        return "success";
    }
}

如果校验通不过返回这样的报文:

这种方式返回的报文不能控制,我们来看第二种方案:

 

工具类;

/**
 * hibernate-validator校验工具类
 */
public class ValidatorUtils {
	private static Validator validator;

	static {
		validator = Validation.buildDefaultValidatorFactory().getValidator();
	}

	/**
	 * 校验对象
	 * 
	 * @param object
	 *            待校验对象
	 * @param groups
	 *            待校验的组
	 * @throws CustomException
	 *             校验不通过，则报RRException异常
	 */
	public static void validateEntity(Object object, Class... groups) throws CustomException {
		Set> constraintViolations = validator.validate(object, groups);
		if (!constraintViolations.isEmpty()) {
			ConstraintViolation
