java - spring 4 @RequestBody 中的未知参数验证

Question

我有一个像下面这样的春假服务

@RequestMapping(value = {"/is"}, method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<ISResponce> createService(@RequestBody Service service)
{
    .................
}

请求正文像::

{
  "customer" : {
    "extUserFullName" : "9999abcdefgh",
    "extUserName" : "999999abcdefgh",
    "extUserPassword" : "qwe"

  },

  "service" : {
    "ol" : 400,
    "sTag" : 512,
    "cTag" : 3333,
    "packageID" : "ABCDE",
    "custType" : "",
    "custSegmentation" : ""
  }
}

当我在请求中提供一些未知(额外)参数“test”时，它正在接受。但是我想在下面的场景中抛出异常。

{
  "customer" : {
    "extUserFullName" : "9999abcdefgh",
    "extUserName" : "999999abcdefgh",
    "extUserPassword" : "qwe"

  },

  "service" : {
    "ol" : 400,
    "test": "test",
    "svTag" : 512,
    "cvTag" : 3333,
    "packageID" : "ABCDE",
    "custType" : "",
    "custSegmentation" : ""
  }
}

spring.xml 看起来像

有人，请帮助我。提前致谢)!!!

Answer 1

您需要在配置文件中设置FAIL_ON_UNKNOWN_PROPERTIES。

这里是一个 java 配置的例子，它覆盖了所有默认的 json 反序列化器，你的应用程序应该在未知属性上抛出异常。

@Bean
public MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
    ObjectMapper mapper = new ObjectMapper();

    mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, true)
    MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter(mapper);
    return converter;
}

下面应该是等效的 XML。

<bean id="jacksonObjectMapper" class="com.fasterxml.jackson.databind.ObjectMapper" />
<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetObject" ref="jacksonObjectMapper" />
    <property name="targetMethod" value="configure" />
    <property name="arguments">
        <list>
            <value type="com.fasterxml.jackson.databind.DeserializationFeature">FAIL_ON_UNKNOWN_PROPERTIES</value>
            <value>true</value>
        </list>
    </property>
</bean>

<bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
    <property name="objectMapper" ref="jacksonObjectMapper" />
</bean>
