SpringMVC 参数校验

概述

需要对Post请求的表单数据进行简单校验。

Maven 配置

Bean Validation API 1.1:

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>1.1.0.Final</version>
</dependency>

Hibernate Validator 5.0.1.Final:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>5.0.1.Final</version>
 </dependency>

Spring MVC

配置

在application-context.xml文件中加入下面一行：

1	<mvc:annotation-driven />

controller

在需要校验的model对象前面加上@Valid注解(javax.validation.Valid):

@RequestMapping(
      value = "/v1/live/send/gift", method = RequestMethod.POST)
  @Response
public WebResult requestSendGift(HttpServletRequest request, @Valid @ModelAttribute SendGiftForm sendGiftForm, BindingResult bindingResult) {
   }

在controller方法里面加上参数判断：

1
2
3

if (bindingResult.hasErrors()) {
        throw new IllegalArgumentException("request params must be not null.");
  }

Validator Model

在需要校验的model字段前面加上注解(hibernate validator):

public class SendGiftForm {
  @NotNull
  private Long roomId; 
  @NotNull
  private Long liveId; 
  
 }
