尝试构建Web服务时的ContainerException
我收到一个ERROR ，表示Resource Config没有root resource class 。这是我的网络服务代码：
public class MapErpService { //first a URI for each resource,create using PUT DBUtils db; MapErpService() { db=new DBUtils("zmaperp", "root", "root"); } @PUT @Path("/{objtype}/{objkey}") @Consumes(MediaType.APPLICATION_JSON) public Response createGeometry(@PathParam("objtype") String objtype,@PathParam("objkey") String objkey,JSONObject obj) { //generate gisuniqkey here JSONObject geo=(JSONObject) obj.get("geometry"); String gisuniqkey=(String) obj.get("gisuniqkey"); String wkt=db.convertToWKT(geo.toJSONString()); if(db.insertGeometryValues(gisuniqkey, objkey, objtype, wkt)) { System.out.println("Data inserted successfully using PUT with objkey: "+objkey); return Response.status(201).entity("Data inserted successfully using PUT with objkey: "+objkey).build(); } else { System.out.println("Data could not be inserted successfully"); return Response.status(500).entity("Data inserted successfully using PUT with objkey: "+objkey).build(); } } @POST @Path("/{objtype}") @Consumes(MediaType.APPLICATION_JSON) public Response createGeometryUsingPost(@PathParam("objtype")String objtype,JSONObject obj) { //both gisuniqkey and objkey have to be generated by magic here... JSONObject geo=(JSONObject) obj.get("geometry"); String gisuniqkey=(String) obj.get("gisuniqkey"); String objkey=(String)obj.get("objkey"); String wkt=db.convertToWKT(geo.toJSONString()); if(db.insertGeometryValues(gisuniqkey, objkey, objtype, wkt)) { //set response code to 201(??) here System.out.println("Data inserted successfully using PUT with objkey: "+objkey); return Response.created(URI.create("http://localhost:8180/"+"GoogleMapsLoadingTest/"+objtype+"/"+objkey)).status(201).entity("Data inserted successfully using POST with objkey: "+objkey).build(); } else //set response code 404?? System.out.println("Data could not be inserted successfully"); return Response.status(201).entity("Data could not be inserted successfully").build(); } @GET @Path("/{objtype}/{objkey}") @Produces(MediaType.APPLICATION_JSON) public JSONObject getGeometry(@PathParam("objtype")String objtype,@PathParam("objkey") String objkey) { ResultSet rs=db.queryValue(objkey, objtype); JSONObject res=null; try { if(rs.next()) { String wkt=rs.getString("AsText(Geometry)"); res=db.convertToGeoJSON2(wkt); } } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } return res; } @PUT @Path("/{objtype}/{objkey}") @Consumes(MediaType.APPLICATION_JSON) public Response updateGeometry(@PathParam("objkey") String objkey,@PathParam("objtype") String objtype,JSONObject obj) { String gisuniqkey=(String) obj.get("gisuniqkey"); JSONObject geo=(JSONObject) obj.get("geometry"); String wkt=db.convertToWKT(geo.toJSONString()); if(db.updateGeometryValue(objkey, objtype, wkt)) { System.out.println("The update operation was successful for objkey: "+objkey); return Response.status(200).entity("The update operation was successful for objkey: "+objkey).build(); } else //send 500 Server Error here System.out.println("The update operation failed completely"); return Response.status(500).entity("The update operation failed completely").build(); } @DELETE @Path("/{objkey}/{objtype}") public Response deleteGeometry(@PathParam("objkey") String objkey,@PathParam("objtype") String objtype){ if(db.delete(objkey, objtype)){ System.out.println("The delete operation was successful"); return Response.status(200).entity("The delete operation was successful").build(); } else { System.out.println("The delete operation failed miserably"); return Response.status(500).entity("The delete operation failed miserably").build(); } } //how do I do multiple...a basic attempt using the POST method @POST @Path("/{objtype}") @Consumes(MediaType.APPLICATION_JSON) @Produces(MediaType.APPLICATION_JSON) public JSONObject getMultiGeometry(@PathParam("objtype") String objtype,JSONObject body){ JSONObject res=null; JSONArray itab= (JSONArray) body.get("itab"); ArrayList keys=new ArrayList(); for(int i=0;i<itab.size();i++) { JSONObject keyObj=(JSONObject) itab.get(i); String objkey=(String) keyObj.get("objkey"); keys.add(objkey); System.out.println("\nobjkey: "+objkey); } ResultSet rs=db.queryValues(keys); try { ArrayList wktList=new ArrayList(); while(rs.next()) { String wkt=rs.getString("AsText(GEOMETRY)"); //String geo=db.convertToGeoJSON(wkt).toJSONString(); //System.out.println("\nwkt: "+wkt+"\tgeoJSON: "+geo); wktList.add(wkt); } res=db.createGeometryCollection(wktList); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } return res; } }
这是我的web.xml ：
GoogleMapLoadingTest Jersey REST Services com.sun.jersey.spi.container.servlet.ServletContainer com.sun.jersey.config.property.packages com.hastha.maperp.webservice 1 Jersey REST Services /*
更新：
添加应用程序类没有任何效果：
public class MapErpApplication extends Application { public Set<Class> getClasses() { Set<Class> res=new HashSet<Class>(); res.add(MapErpService.class); res.add(MapErpGetService.class); return res; } }
我仍然得到这个错误：

UPDATE2：
现在，从浏览器执行GET请求时出现此错误
使用@Path("/erp") （或其他字符串）注释MapErpService类。
