@Valid + BindingResult 拦截接口错误信息 ###测试发现: HttpServletRequest request, HttpServletResponse response, 需要去掉...public ResponseData testMvc(@Valid @RequestBody ReqVo reqVo,BindingResult bindingResult) { logger.info...("testMvc controller params={}",GsonUtils.toJson(reqVo)); if (bindingResult.hasErrors()) { Optional error = bindingResult.getFieldErrors().stream().findFirst(); throw new InputErrorException
加上以下依赖即可 <dependency> <groupId>org.hibernate</groupId> ...
@Valid或@Validate的参数后必须紧挨着一个BindingResult 参数,否则spring会在校验不通过时直接抛出异常 public InternalResponseVo updateSource...(@Validated @RequestBody(required = false) SourceValidator sourceValidator, @PathVariable int id, BindingResult...bindingResult) {} 如果出现错误会直接抛出异常,方法不会执行。...只需要修改bindingresult的位置使其挨着校验入参即可 修改后: public InternalResponseVo updateSource(@Validated @RequestBody...(required = false) SourceValidator sourceValidator, BindingResult bindingResult, @PathVariable int id
groupId> modelmapper 1.1.0 controller请求中BindingResult...bindingResult通过bindingResult.hasErrors()判断是否报错,下列模板代码可以学习 /** * 新增房源接口 * @param houseForm * @param...bindingResult * @return */ @PostMapping("admin/add/house") @ResponseBody public ApiResponse addHouse...(@Valid @ModelAttribute("form-house-add") HouseForm houseForm, BindingResult bindingResult) { if...(bindingResult.hasErrors()) { return new ApiResponse(HttpStatus.BAD_REQUEST.value(), bindingResult.getAllErrors

(value = 18,message = "未成年禁止入内") private Integer age; ② 其次在controller层的方法的要校验的参数上添加@Valid注解,并且需要传入BindingResult...对象,用于获取校验失败情况下的反馈信息,如下代码: @PostMapping("/girls") public Girl addGirl(@Valid Girl girl, BindingResult...bindingResult) { if(bindingResult.hasErrors()){ System.out.println(bindingResult.getFieldError...getDefaultMessage()); return null; } return girlResposity.save(girl); } bindingResult.getFieldError.getDefaultMessage
.#")private double salary;2.转换失败后处理①BindingResultSpringMVC在捕获到类型转换失败错误时会将相关信息封装到BindingResult对象传入到目标handler...使用BindingResult检测绑定失败错误@RequestMapping("/convert")public String convertFail(Employee employee, BindingResult...bindingResult) { //检测是否存在“数据绑定”错误 boolean hasErrors = bindingResult.hasErrors(); if(
"Hello " + u.getName()) .onErrorResume(WebExchangeBindException.class, e -> Mono.just(bindingResult2String..."Hello " + u.getName()) .onErrorResume(WebExchangeBindException.class, e -> Mono.just(bindingResult2String...ResponseBody public String handleBindException(WebExchangeBindException bindException) { return bindingResult2String...VALUE) @ResponseBody public Mono validateRawReqBody(@RequestBody @Validated User user /**,BindingResult...bindingResult**/) { //注意在参数添加BindingResult bindingResult会报错,还是交给ExceptionHandler那里处理 return
bindingResult) { if(bindingResult.hasErrors()) { log.error("【注册用户】参数不正确,user={},...,即一个校验类对应一个校验结果: foo(@Validated Foo foo, BindingResult fooBindingResult ,@Validated Bar bar, BindingResult...bindingResult) { if(bindingResult.hasErrors()) { log.error("参数不正确,user={}, msg={...") public void live(@Validated @RequestBody User user, BindingResult bindingResult) { if(...bindingResult.hasErrors()) { log.error("参数不正确,user={}, msg={}", user, bindingResult.getFieldError
在控制器的方法参数中,需要通过声明BindingResult参数来获得验证出错的信息,然后使用@Valid注解来配置哪个pojo对象需要校验,控制器代码如下: package org.zero01.test...是配对出现,并且形参顺序是固定的(一前一后),不然就会返回400状态码 public String test(@Valid UserRegister userRegister, BindingResult...bindingResult, Model model) { // 判断是否有异常 if (bindingResult.hasErrors()) {...bindingResult, Model model) { if (bindingResult.hasErrors()) { System.out.println...("客户端的请求数据异常,所有的异常如下:"); for (FieldError fieldError : bindingResult.getFieldErrors()) {
Controllerpublic class MyFirstController { @RequestMapping("/form") public String form(@Valid User user, BindingResult...bindingResult) { int errorCount = bindingResult.getErrorCount(); if (errorCount !...= 0) { // 获取校验错误字段及错误信息 List fieldErrors = bindingResult.getFieldErrors...bindingResult, Model model) { int errorCount = bindingResult.getErrorCount(); if (errorCount...= 0) { // 获取校验错误字段及错误信息 List fieldErrors = bindingResult.getFieldErrors
message="错误信息,配置在专门的文件中") private Date createtime; } //在需要校验的pojo前面添加@Validated注解,在需要校验的pojo后面添加BindingResult...bindingResult接受校验出错信息 //注意:@Validated和BindingResult bindingResult是配对出现,并且形参顺序一致。...public String editItemsSubmit( HttpServletRequest request, @Validated ItemsCustom itemsCustom, BindingResult...bindingResult)throws Exception{...}...bindingResult)throws Exception{...}
public class HelloController { @RequestMapping("/hello") public Object index(@Valid User user, BindingResult...bindingResult){ List error=null; //返回boolean 是为了验证@Validated后面bean 里是否有不符合注解条件的错误信息...if(bindingResult.hasErrors()){ //获得所有错误信息返回list集合 error=bindingResult.getAllErrors
public class FirstController { @RequestMapping("/first") public Object first(@Valid User user, BindingResult...bindingResult) { return "first controller"; } @RequestMapping("/second") public...如果校验不通过,那么错误信息就会封装到BindingResult对象了,可以通过bindingResult的相关方法获取详细的错误信息并返回给用户。...如果不加BindingResult则会抛出异常。 此时即可完成表单类,或者用户注册之类的类似请求的参数校验了,可以选择获取bindingResult信息后直接return给用户。...而49到62行,主要是判断是否存在BindingResult参数,如果有,说明有校验javaBean的意图,如果BindingResult有值,说明存在校验不通过的信息,那么就可以做处理了。
String email; private Integer gender; } Controller 中需要校验的参数Bean前添加 @Valid 开启校验功能,紧跟在校验的Bean后添加一个BindingResult...,BindingResult封装了前面Bean的校验结果。...bindingResult) { if (bindingResult.hasErrors()) { Map map = new...HashMap(); bindingResult.getFieldErrors().forEach( (item) -> { String...bindingResult = null; if (e instanceof MethodArgumentNotValidException) { bindingResult

} // 各种getter / setter / 构造器 } 3.2 开启校验 在Controller方法入参中需要校验的参数前加入@Validated()表明需要校验,后方要加@BindingResult...@Validated()和@BindingResult二者一前一后紧密相连的,中间不能有任何数值相隔。...bindingResult) { // 判断是否有错 if (bindingResult.hasErrors()) { // 获取字段上的错误 FieldError...errors = bindingResult.getFieldError(); // 输出message信息 return (errors.getDefaultMessage...bindingResult) { if (bindingResult.hasErrors()) { FieldError errors = bindingResult.getFieldError
BindingResult 用来接收错误信息 @PostMapping(value = "/girl/add") public Girl add(@Validated Girl girl, BindingResult...bindingResult) { if(bindingResult.hasErrors()){ System.out.println(bindingResult.getFieldError...} } 不同状态返回相同格式的结果 @PostMapping(value = "/girl/add") public Result add(@Validated Girl girl, BindingResult...bindingResult) { if (bindingResult.hasErrors()) { return ResultUtils.error(1, bindingResult.getFieldError
