В моем проекте, использующем restful json, у меня есть несколько файлов, следующих как:

web.xml:

 <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/root-context.xml</param-value>
</context-param>

<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- Processes application requests -->
<servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
  

Servlet-context.xml

Мой класс Jersey:

 @Path("/marker")
public class GetLatLongMapMarker {

@GET 
@Path("/doMarker")
@Produces("application/json;charset=utf-8")
public String doMap() {

    String carMaps = null;

    ArrayList<CarMap> mapList = new ArrayList<CarMap>();

        try {
            mapList = DBConnection.getAllMapMarker();
            Gson gson = new Gson();
            carMaps = gson.toJson(mapList); 
        } 

        catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }   

    return carMaps;
    }
}
  

Когда я хочу получить данные из json по URL:

 http://192.168.1.221:9999/restfulspringmvc/maker/doMarker
  

произошло исключение, и это log:

 02:12:23.239 [http-bio-9999-exec-3] DEBUG o.s.web.servlet.DispatcherServlet   - DispatcherServlet with name 'appServlet' processing GET request for   [/restfulspringmvc/maker/doMarker]
02:12:23.239 [http-bio-9999-exec-3] DEBUG o.s.w.s.m.m.a.RequestMappingHandlerMapping - Looking up handler method for path /maker/doMarker
02:12:23.240 [http-bio-9999-exec-3] DEBUG o.s.w.s.m.m.a.RequestMappingHandlerMapping - Did not find handler method for [/maker/doMarker]
02:12:23.241 [http-bio-9999-exec-3] WARN  o.s.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/restfulspringmvc/maker/doMarker] in DispatcherServlet with name 'appServlet'
02:12:23.245 [http-bio-9999-exec-3] DEBUG o.s.web.servlet.DispatcherServlet - Successfully completed request
  

Как я могу исправить эту конфигурацию?
Большое вам спасибо!!

Вы определяете сопоставления запросов в своем классе jersey таким образом:

 @Path("/marker")
public class GetLatLongMapMarker {

@GET 
@Path("/doMarker")
@Produces("application/json;charset=utf-8")
public String doMap() {
  

Что приводит к /[context-path]/marker/doMarker, но вы запрашиваете этот URL http://192.168.1.221:9999/restfulspringmvc/maker/doMarker .

Поэтому измените maker в своем запросе на marker , и вы сможете его достичь
