需要参数验证的实体类 ![]() ![]()
public class User implements Serializable { /** */
private static final long serialVersionUID = -4099344363882857295L;
@NotBlank(message = "用户名不能为空")
private String userId; @NotBlank(message = "身份证号不能为空")
private String certNo;
/**此处省略*/ } 验证的工具类
public class ValidationUtils {
/**
* 使用hibernate的注解来进行验证
* failFast：true 快速失败返回模式 false 普通模式
*/

/**
* 功能描述:
* 〈注解验证参数〉
*/
public static <T> Map<String, Object> validate(T obj) {
try {
Set<ConstraintViolation<T>> constraintViolations = validator.validate(obj);

@RequestMapping(value = "/calcLoan.do")
public String calcLoan(@RequestBody BaseReqVo baseReqVo, HttpServletRequest request, HttpServletResponse response) {

}
//业务逻辑
} 当然也可以通过以下方式-----------------
@RequestMapping(value = "/saveBaseInfo", method = RequestMethod.POST, produces = { "application/json;charset=UTF-8" })
@ResponseBody
public Map<String, Object> saveBaseInfo(HttpServletRequest request, HttpServletResponse response,
@Valid ApplyBasicInfoForm basicInfoForm, BindingResult result) {
Map<String, Object> resultMap = new HashMap<String, Object>();
if (result.hasErrors()) {
List<FieldError> fieldErrors = result.getFieldErrors();
for (FieldError error : fieldErrors) {
MyLog4j.textInfo("基本信息校验异常：" + error.getField() + ",错误消息：" + error.getDefaultMessage());
return AjaxUtils.createMapByMsg(ConstantParamUtils.RESULT_CODE_FAIL, error.getDefaultMessage(),
basicinfo.getUrl(), basicinfo.getToken(), resultMap);
}
} //TODO }
public class ApplyBasicInfoForm {
/**单位名称*/
@NotBlank(message = "请填写完整的资料！")
@Length(max = 150, message = "单位名称不能大于150字符")
@Pattern(regexp = "^[\u4e00-\u9fa5a-zA-Z0-9]+$", message = "单位名称包含非法字符")
private String companyName;
/**单位电话*/
@NotBlank(message = "请填写完整的资料！")
@Length(max = 20, message = "单位电话大于20字符")
private String companyPhone;
//省略--------
