如何使用Jersey将依赖项注入到资源中?

这是一个很好的关于新泽西州春季注射的博客 http://javaswamy.blogspot.com/2010/01/making-jersey-work-with-spring.html

package com.km.services;  

import javax.ws.rs.GET;  
import javax.ws.rs.Path;  
import javax.ws.rs.Produces;  
import org.springframework.context.annotation.Scope;  
import org.springframework.stereotype.Component;  
import com.sun.jersey.spi.inject.Inject;  
import com.km.spring.SimpleBean;  

@Path("/hello")  
@Component  
@Scope("request")  
public class HelloResource {  

   @Inject private SimpleBean simpleBean;  

   @GET  
   @Produces("text/plain")  
   public String getMessage() {  
    return simpleBean.sayHello();  
   }  
} 

出于我的目的,配置非常困难,所以我使用静态spring解析器工厂来解析bean。如。

private SimpleBean simpleBean = SpringBeanFactory.getBean("mySimpleBean");

您不需要Spring或Guice来注入ServletConfig。泽西岛通过它自己的注射机制。请参阅Jersey samples发行版附带的简单servlet示例。下面是将HttpServletRequest和ServletConfig注入资源的示例代码:

@Path("/resource1")
public class ResourceBean1 {

    @Context
    HttpServletRequest servletRequest;

    @Context
    ServletConfig servletConfig;

    @GET
    @Produces("text/plain")
    public String describe() {
        return "Hello World from resource 1 in servlet: '" +
                servletConfig.getServletName() +
                "', path: '" +
                servletRequest.getServletPath() +
                "'";
    }

}
