spring  mvc校验

1，引入jar

<groupId>javax.validation</groupId>

<artifactId>validation-api</artifactId>

</dependency>

<groupId>org.hibernate</groupId>

<artifactId>hibernate-validator</artifactId>

</dependency>

2，配置

xml:

</bean>

</bean>

</bean>

ValidationMessages:

notEmpty.message=\{field\}\\u4E0D\\u80FD\\u4E3A\\u7A7A

phone.message=\\u624B\\u673A\\u53F7\\u4E0D\\u6B63\\u786E

number.message=\{field\}\\u5FC5\\u987B\\u4E3A\\u7EAF\\u6570\\u5B57

json.message=\{field\}\\u4E0D\\u662FJson\\u5B57\\u7B26\\u4E32\\u7C7B\\u578B

jsonArray.message=\{field\}\\u4E0D\\u662FJsonArray\\u5B57\\u7B26\\u4E32\\u7C7B\\u578B

3，使用

@RequestMapping("apply")

@ResponseBody

public ApiResponse insureApply(@Valid @RequestBody InsureApplyRequest insureApplyRequest, Errors errors) throws Exception \{

//验证参数

checkError(errors);----spring入参的一级校验

Class insureCheckBean = factoryBank.getInsureCheckBean(insureApplyRequest.getBankType());

Object object = JSONObject.parseObject(insureApplyRequest.getInsureInfo(), insureCheckBean);

String checkResult = BeanUtils.checkBean(object);----里面的json转化成实体之后的二级校验

可以放在base control

/\*\*

\* 校验请求参数

\* @param errors

\* @throws ParamException

\*/

public void checkError(Errors errors) throws ParamException \{

if(errors.hasErrors())\{

List<FieldError> fieldErrors = errors.getFieldErrors();

StringBuffer buffer = new StringBuffer();

for(FieldError fieldError:fieldErrors)\{

//String field = fieldError.getField();

String message = fieldError.getDefaultMessage();

buffer.append(message).append("; ");

throw new ParamException(CodeEnum.CODE\_0002.getMsg()+"\{"+buffer.toString()+"\}");

自定义校验（一般用于二级校验）

1，实体中用相关的注解--可以自定义也可以用框架的（此时没有用springmvc本身校验）

变化大的字段不必常规建立一个表涵盖所有字段，只要用一个字段存储json即可，用的时候根据类型转化   这一个字段所在实体可以spring入参的时候校验

里面的那个字段转化成实体后就不能在入参的时候校验，可以自定义工具类，结合注解（校验的时候可以spring valid和自定义根据注解自己用工具类校验结合---分层校验）
