Question

我正在使用@Path注释来获取基于＆＃39; State＆＃39;来自mongo DB的参数。在执行代码时，我得到了上述异常。代码如下：

//State.Java
    @GET  
    @Path("/{State}")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public Object[] addBuild2(@PathParam("State") String State  ) throws UnknownHostException

    { System.out.println("ïnside Location");
    Location loc = new Location();

    List<DBObject> basicDBList=(List<DBObject>) loc.getState2();
        System.out.println("ïnside State2===>"+basicDBList);
        return basicDBList.toArray();

    }

//Location.Java
public List<DBObject> getState2() throws UnknownHostException {
    DB db=ConnectToDB.getConnection();
    DBCollection collection = db.getCollection("location");
    BasicDBObject obj = new BasicDBObject();
     List<BasicDBObject> andQuery = new ArrayList<BasicDBObject>();
     andQuery.add(new BasicDBObject("Country", "USA"));

  andQuery.add(new BasicDBObject("State", new ObjectId("State")));
   obj.put("$and", andQuery); 


    BasicDBObject fields = new BasicDBObject();
        fields.put("_id", 0);

        DBCursor cursor = collection.find(obj, fields);
        List<DBObject> obj1 =cursor.toArray();



        System.out.println(""+obj1);
            }

        return obj1;
}
}

The error Stack trace is as below:

Please tell what the issue is while using @Path for Rest API as I am using 'State' as a parameter to fetch all the data for the corresponding state. Thanks in advance.

java.lang.IllegalArgumentException：ObjectId的无效十六进制表示形式在Mongo数据库中为@Path Rest API
