Question

我正在使用Java 1.7，Spring Framework 3.1和Jersey 1.8。

我创建了一个简单的类TeamData

通过localhost:8080/team/{id}我可以从我的数据库中收到ID为{id}的团队名称。

@Path("team/")
public class TeamData {

@GET
@Path("{id}")
public Response getTeamById(@PathParam("id") int id) {
    TeamServiceImpl teamServiceBean = getTeamServiceBean();
    Team team = teamServiceBean.getTeamById(id);
    output = "Team name : " + team.getTeamName();
    return Response.status(200).entity(output).build();
}


/**
* Method gets bean from ApplicationContext
*/
public TeamServiceImpl getTeamServiceBean() {
    ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
            "bean-spring.xml");
    TeamServiceImpl teamServiceBean = (TeamServiceImpl) applicationContext
            .getBean("teamService", TeamServiceImpl.class);
    return teamServiceBean;
    }

}

如何在加载时初始化应用程序上下文？

有没有办法在Servlets中做点什么？

public class HelloServlet extends HttpServlet {

    private ApplicationContext ac;

    @Override
    public void init() throws ServletException {
        super.init();
        ac = new ClassPathXmlApplicationContext("bean-spring.xml");
    }

protected void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
          // TODO:
          }

   }

您无需自己创建上下文。只需使用jersey-spring集成模块即可。让泽西为你创造和维护它。

<dependency>
    <groupId>com.sun.jersey.contribs</groupId>
    <artifactId>jersey-spring</artifactId>
    <version>1.8</version>
</dependency>

您应该可以在Jersey资源类中@Autowired提供{{1}}服务，没有任何问题。当然需要一些配置。
