解释：
L9~L12：实现自动加载Spring的配置文件
L15~L18：定义Resource资源类
此时，Source中不需要实现javax.ws.rs.core.Application方法
同时，L36~L39处的设置就不需要了
如果这段设置不做的话，则需要实现javax.ws.rs.core.Application方法，如下：
1 package com.test.info.ics; 2 3 import java.util.HashSet; 4 import java.util.Set; 5 6 import javax.ws.rs.core.Application; 7 8 import com.test.info.ics.resources.UserResources; 9 10 11 public class ServiceApplication extends Application { 12 HashSet<Object> singletons = new HashSet<Object>(); 13 private Set<Class<?>> empty = new HashSet<Class<?>>(); 14 15 public ServiceApplication() { 16 empty.add(UserResources.class); 17 } 18 19 @Override 20 public Set<Class<?>> getClasses() { 21 return empty; 22 } 23 24 @Override 25 public Set<Object> getSingletons() { 26 return singletons; 27 } 28 }
同时，需要设置L36~L39。
L21~L28：两个Listener是为了启动Spring
