如何避免 REST API 发布请求末尾的后缀？答案

【问题标题】：How to avoid a suffix at the end of REST API post request?如何避免 REST API 发布请求末尾的后缀？
【发布时间】：2016-12-19 09:37:24
【问题描述】：

我在我的servlet-config.xml 中添加了以下内容，并摆脱了在 spring mvc 中 REST API 的 GET 请求末尾添加 .json 的后缀，但对于 post API，我仍然需要 .json 在结束

<property name="defaultContentType" value="application/json" />

请告诉我如何才能避免 .json 最终发出 POST 请求。

下面是我的servlet-config.xml：

<?xml version="1.0" encoding="UTF-8"?>

                        </constructor-arg>

                </bean>
            </list>
        </property>
    </bean>

</beans>

下面是我的控制器

@Controller
public class ObjectResource {

    @RequestMapping(value = "/get_request/{param1}/{param2}")
    public ResponseEntity<\Object> getObjectDetails(@PathVariable String param1,@PathVariable String param2){
        return objectServiceBean.getObjectDetails(param1,param2);
    }

    @RequestMapping(value = "/post-request/",method=RequestMethod.POST)
    public ResponseEntity<Response> updateObjectDetails(@RequestBody String updateObjectString){
        JSONObject updateObject = null;
        Response response = new Response();
        Object object = new Object();
        try
        {
            updateObject = new JSONObject(updateObjectString);
        }
        catch(JSONException e)
        {
            response.setResponse("Incorrect JSON structure:" + e.toString());
            return ResponseEntity.status(HttpStatus.BAD_REQUEST).body(response);
        }
        return objectServiceBean.updateObjectDetails(object);
    }
}

【问题讨论】：

你用的是哪个spring版本，是3.2吗？

【解决方案1】：

您还定义了以下配置，这与您的默认内容类型设置相矛盾，

<constructor-arg>
       <bean class="org.springframework.web.accept.PathExtensionContentNegotiationStrategy">
              <constructor-arg>
                     <map>
                          <entry key="json" value="application/json">    </entry>
                          <entry key="xml" value="application/xml">    </entry>
                     </map>
              </constructor-arg>
       </bean>
</constructor-arg>
