jersey2与spring3在java程序中整合实现http服务获取上下文问题

Question

问题：jersey2与spring3在java程序中整合实现http服务（不是部署在web容器中的web应用）

客户端通过http://localhost:8087/prov43/nmggz/dic/update/BAB063  

调用  dicService的  updateDict  方法， 但dicService为null， 没有spring上下文

加入jersey-spring3-2.6.jar后，启动服务就报，找不到applicationContext.xml配置文件，我的配置文件在

“D:\\省svn\\新一代中间业务平台\\开发或操作手册\\省平台\\cpabprov\\exf\\config\\spring.xml”  -- 见下面的单元测试类

import java.net.URI;

import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component("restServer")
public class RESTServer {

	/**  服务主机ip   **/
	@Value("${prov43.httpserver.base_uri}")
	public String base_uri;
	
	public HttpServer startServer() {
				
		final ResourceConfig rc = new ResourceConfig().packages("com.psbc.pfpj.prov43");

		System.out.println("###################################");
		System.out.println("启动服务......");
		System.out.println("base_uri:"+base_uri);
		return GrizzlyHttpServerFactory.createHttpServer( URI.create(base_uri), rc);
	}

	public String getBase_uri() {
		return base_uri;
	}

	public void setBase_uri(String base_uri) {
		this.base_uri = base_uri;
	}
	
}

要整合Jersey2和Spring3来实现HTTP服务获取上下文，首先需要在web.xml文件中配置Jersey2的Servlet容器，然后在web.xml文件中配置Spring的ContextLoaderListener，最后在Jersey2的Servlet容器中配置Spring的ApplicationContext。具体步骤如下：
1. 在web.xml文件中配置Jersey2的Servlet容器：
<servlet>
    <servlet-name>Jersey2</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.example.MyApplication</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
2. 在web.xml文件中配置Spring的ContextLoaderListener：
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
3. 在Jersey2的Servlet容器中配置Spring的ApplicationContext：
<init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</init-param>
