Question

我正在将Spring从版本3（基于XML）升级到4.2.4（基于注释）

控制器

@RestController
public class XnetOrderResourceController{
    @Autowired
    private XnetOrderDao orderDao;

    /*
     * GET All Orders
     */
    @RequestMapping(value = "/getAllOrdersInfo", method =RequestMethod.GET, produces="application/json")
     public XnetOrder  get(@RequestParam("Id") Long Id) {
        XnetOrder order=null;
        try{
            if(MiscUtils.isNotEmpty(Id)){
                order=orderDao.get(Id);
            }
        }catch(HibernateException e){
            log.info(ORDER_DETAIL_NOT_AVAILABLE);  
            getLogger().error(e.getMessage());
        }

        return   order;
    }

    /*
     * POST(create new) Orders
     */
    @RequestMapping(value = "/insertOrders", method =RequestMethod.POST,  consumes="application/json", produces="application/json")
    public void post(@RequestBody XnetOrder order){
        try{            
            orderDao.post(order);
        }catch(HibernateException e){
            log.info("Creating the Order  operation failed.");
            getLogger().error(e.getMessage());
        }
    }

     /*
      * PUT (update) orders 
      */
    @RequestMapping(value="/updateOrders", method=RequestMethod.PUT, consumes="application/json", produces="application/json")
    public XnetOrder update(@RequestBody XnetOrder order){
        try{
            order=orderDao.put(order);
        }catch(HibernateException e){
            getLogger().error(e.getMessage());
        }

        return order;
    }

    /*
     *  DELETE orders
     */
    @RequestMapping(value="/deleteOrders",method=RequestMethod.DELETE)
    public void delete(@RequestParam("Id") Long Id){
        try{
            if(MiscUtils.isNotEmpty(Id)){
                orderDao.delete(Id);
                log.info("Order is successfully deleted");
            }
        }catch(HibernateException e){
            log.info(XNET_PRODUCT_INVALID_ERROR_MESSAGE);
            getLogger().error(e.getMessage());
        }
    }
}

弹簧servlet.xml中

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

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

        <property name="mediaTypes">

                json=application/json
            </value>
        </property>
    </bean>

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

我的类路径中的JAR文件是 -

jackson-annotations-2.2.3.jar, 
jackson-core-2.2.3.jar, 
jackson-databind-2.3.3.jar, 
jackson-mapper-asl-1.9.13.jar, 
jackson-2.1.0-all.jar

我能够执行GET操作，该操作成功返回JSON值，但PUT和POST操作无法正常工作。我使用Postman作为REST客户端。我还尝试在将标头值PUT设置为Content-Type之后传递aplication/json操作的网址，但它始终返回

错误415 - 不支持的媒体类型。

我收到以下回复标题：

Connection     → close
Content-Length → 903
Content-Type   → text/html; charset=UTF-8
Date           → Sat, 14 May 2016 09:16:57 GMT
X-Powered-By   → Servlet/2.5 JSP/2.1

有人可以建议如何让PUT和POST操作起作用吗？

Answer 1

如果为控制器方法指定produces，则还需要在请求中设置Accepts标题。

错误415 - Spring 4不支持的介质类型
