spring mvc校验
1，引入jar
2，配置
xml:
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
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）
