javaxbean验证对方法参数无效

javax验证在方法参数上不起作用。。这是一个测试代码，没有一个javax验证对方法参数有效

@RequestMapping(value = "/{id}", method = RequestMethod.PUT, params = "action=testAction")
public Test update(
        @Size(min = 1) @RequestBody List<String> ids,
        @Min(3) @PathVariable String name) {
    return doSomething(ids, name);
}

及

--解决方案--

按照接受的答案执行所有步骤。 另一个增加是类级别的注释

@Validated
class UserController
{
   @RequestMapping(value = "/{id}", method = RequestMethod.PUT, params ="action=testAction")
   public Test update(@Size(min = 1) @RequestBody List<String> ids,@Min(3) @PathVariable String name) {
    return doSomething(ids, name);
}
}

@已验证
类用户控制器
{
@RequestMapping（value=“/{id}”，method=RequestMethod.PUT，params=“action=testAction”）
公共测试更新（@Size（min=1）@RequestBody列表ID，@min（3）@PathVariable字符串名称）{
返回剂量表（ID、名称）；
}
}

您需要注册bean来启动方法级验证注释

委托JSR-303提供程序执行方法级 注释方法的验证

那么

@RequestMapping（value=“/{id}”，method=RequestMethod.PUT）
公共测试更新(
@RequestBody列表ID的大小（最小值=1），
@Min（3）@PathVariable（“id”）字符串名称）{
返回剂量表（ID、名称）；
}

如果您想处理验证异常

@ExceptionHandler(value = { ConstraintViolationException.class })
 @ResponseStatus(value = HttpStatus.BAD_REQUEST)
 public String handleResourceNotFoundException(ConstraintViolationException e) {
      Set<ConstraintViolation<?>> violations = e.getConstraintViolations();
      StringBuilder strBuilder = new StringBuilder();
      for (ConstraintViolation<?> violation : violations ) {
           strBuilder.append(violation.getMessage() + "\n");
      }
      return strBuilder.toString();
 }

@ExceptionHandler（值={ConstraintViolationException.class}）
@ResponseStatus（值=HttpStatus.BAD_请求）
公共字符串句柄ResourceNotFoundException（ConstraintViolationException e）{
SET谢谢你的详细回答，我忘了添加bean配置，另一件事是我忘了在类级别添加@validated注释。现在它可以工作了。除此之外，你需要将@validated添加到类型级别，否则类将不会触发验证。我只是在我的类中添加了@validated，它就工作了。
@Validated
class UserController
{
   @RequestMapping(value = "/{id}", method = RequestMethod.PUT, params ="action=testAction")
   public Test update(@Size(min = 1) @RequestBody List<String> ids,@Min(3) @PathVariable String name) {
    return doSomething(ids, name);
}
}

  @Bean
     public MethodValidationPostProcessor methodValidationPostProcessor() {
          return new MethodValidationPostProcessor();
     }

@RequestMapping(value = "/{id}", method = RequestMethod.PUT)
public Test update(
        @Size(min = 1) @RequestBody List<String> ids,
        @Min(3) @PathVariable("id") String name) {
    return doSomething(ids, name);
}

@ExceptionHandler(value = { ConstraintViolationException.class })
 @ResponseStatus(value = HttpStatus.BAD_REQUEST)
 public String handleResourceNotFoundException(ConstraintViolationException e) {
      Set<ConstraintViolation<?>> violations = e.getConstraintViolations();
      StringBuilder strBuilder = new StringBuilder();
      for (ConstraintViolation<?> violation : violations ) {
           strBuilder.append(violation.getMessage() + "\n");
      }
      return strBuilder.toString();
 }
