springboot的Validator的帮助类

ValidatorUtils

public class ValidatorUtils { private static Validator validator; static { validator = Validation.byDefaultProvider().configure().messageInterpolator( new ResourceBundleMessageInterpolator(new MessageSourceResourceBundleLocator(getMessageSource()))) .buildValidatorFactory().getValidator(); } private static ResourceBundleMessageSource getMessageSource() { ResourceBundleMessageSource bundleMessageSource = new ResourceBundleMessageSource(); bundleMessageSource.setDefaultEncoding("UTF-8"); bundleMessageSource.setBasenames("i18n/validation"); return bundleMessageSource; } /** * 校验对象 * @param object 待校验对象 * @param groups 待校验的组 */ public static void validateEntity(Object object, Class<?>... groups) throws BusinessException { Set<ConstraintViolation<Object>> constraintViolations = validator.validate(object, groups); if (!constraintViolations.isEmpty()) { ConstraintViolation<Object> constraint = constraintViolations.iterator().next(); throw new BusinessException(constraint.getMessage()); } } }

Exception

public class BusinessException extends RuntimeException { private String errorCode; public BusinessException() { } public BusinessException(String message) { super(message); } public BusinessException(String errorCode, String message) { super(message); this.errorCode = errorCode; } public BusinessException(String message, Throwable cause) { super(message, cause); } public BusinessException(String errorCode, String message, Throwable cause) { super(message, cause); this.errorCode = errorCode; } public BusinessException(Throwable cause) { super(cause); } public BusinessException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) { super(message, cause, enableSuppression, writableStackTrace); } public String getErrorCode() { return errorCode; } public void setErrorCode(String errorCode) { this.errorCode = errorCode; } }

使用

@GetMapping("/getSysUserListByPage") @ResponseBody @ApiOperation(value = "查询系统用户数据并分页") public ResponseModel getSysUserListByPage(SysUserTabReq req) { ValidatorUtils.validateEntity(req); PageInfo<SysUserTabResp> pageInfo = apiUserService.getSysUserListByPage(req); return ResponseModel.success(pageInfo); }

全局异常处理BusinessException

@ExceptionHandler(value = BusinessException.class) public ResponseModel exceptionHandler(BusinessException e) { return ResponseModel.fail(e.getMessage()); }
