我正在尝试使用jersey和maven从api获取数据。但是出现以下错误：

javax.servlet.ServletException: A MultiException has 3 exceptions.  They are:
1. org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl(requiredType=MusicService,parent=MusicController,qualifiers={},position=-1,optional=false,self=false,unqualified=null,1830564791)
2. java.lang.IllegalArgumentException: While attempting to resolve the dependencies of com.ashwin.lisnepal.controller.MusicController errors were found
3. java.lang.IllegalStateException: Unable to perform operation: resolve on com.ashwin.lisnepal.controller.MusicController

我的控制器类是：

package com.ashwin.lisnepal.controller;

import com.ashwin.lisnepal.response.ResponseGen;
import com.ashwin.lisnepal.service.MusicService;

import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path("/hello")
public class MusicController {

    @Inject
    private MusicService musicService;

    @GET
    @Path("getAllMusic")
    @Produces(MediaType.APPLICATION_JSON)
    public Response getAllMusic() {
        return ResponseGen.success(musicService.getAllMusic());
    }
}

我的服务类别是：

package com.ashwin.lisnepal.service;

import com.ashwin.lisnepal.dao.MusicDao;
import com.ashwin.lisnepal.model.Album;

import org.apache.jcs.JCS;
import org.apache.jcs.access.exception.CacheException;
import org.apache.jcs.engine.control.CompositeCacheManager;
import org.apache.log4j.Logger;

import javax.ejb.Stateless;
import javax.inject.Inject;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;

/**

@Stateless
public class MusicService {

    @Inject
    private MusicDao musicDao;


    private JCS cache;

    public List<Album> getAllMusic() {

        // First, try to get the music list from the cache...
        List albumList = (List) cache.get("musicCache");

        // If the userList does not exist in the cache, build it
        // from the repository request and stick it in the cache.
        if(albumList == null) {

            new MusicDao();
            return musicDao.getAllTopHundredMusic();

           /* cache.put("activeUserList",userList);*/

        }

        return albumList;

    }


}
