一、applicationContext.xml   (spring-framework-2.0.1)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans default-autowire="byName">
     <!-- singleton是單例爲
                 true表示每次都調用Spring都會反射創建新的實例
                 false表示只建立一個實例 估計是保存在上下文對象容器中了。 -->
     <bean id="userservices" class="search.userServices" singleton="false"/>   
</beans>

調用示例代碼：(RegisterAction.java)
package search;

import com.opensymphony.xwork.Action;

public class RegisterAction implements Action{
     //public static final String ISNULL = "isnull";   //自定義WebWork返回類型，用於Global的定義
     private User user = new User();
     private userServices userservices;
     public User getUser() {
         return this.user;
     }
     public void setUser(User user) {
         this.user = user;
     }
     public RegisterAction()
     {
        
     }
     public String execute() throws Exception {
         System.out.println("Start execute 。。。。。。。。。。。。。");
         System.out.println("User="+user);
         System.out.println("username="+user.getUsername());
         System.out.println("password="+user.getPassword());
         System.out.println("email="+user.getEmail());
         System.out.println("age="+user.getAge());
         //System.out.println("trim="+user.getUsername().trim());
