import javax.ws.rs.core.MediaType;

import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;

import com.google.gson.Gson;
import com.sun.jersey.spi.resource.Singleton;
import com.test.bean.User;
import com.test.service.UserService;

@Path("/users")
@Singleton
@Controller
public class UserResource {

    private static Logger logger = Logger.getLogger(UserResource.class);
    @Resource
    private UserService userService;

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getAllUser() {
        List<User> list = null;
        String str = null;
        try {
            list = userService.loadAll();
            str = new Gson().toJson(list);
        } catch (Exception e) {
            logger.error("load all exception : ", e);
        }
        return str;
    }
}

頁面訪問測試

我們現在訪問頁面http://localhost:8080/SSJTest/resource/users

取到返回的json數據。

PS：jersey jar包必須使用同一個版本，本人使用1.13版本測試沒有問題
