SSH框架中 在别的地方获取service 不想注入。

1.重写 ContextLoaderListener  监听器。

package com.ucap.xzsp.util;



import javax.servlet.ServletContext;

import javax.servlet.ServletContextEvent;



import org.springframework.context.ApplicationContext;

import org.springframework.web.context.ContextLoaderListener;

import org.springframework.web.context.support.WebApplicationContextUtils;



public class SpringLoaderListener extends ContextLoaderListener{

    

    @Override

    public void contextInitialized(ServletContextEvent event) {

        // TODO Auto-generated method stub

        super.contextInitialized(event);

        ServletContext context=event.getServletContext();

        ApplicationContext ctx=WebApplicationContextUtils.getRequiredWebApplicationContext(context);

        SpringContextutil.setContext(ctx);

        

    }



}

 2。新建一个辅助类。

package com.ucap.xzsp.util;



import org.springframework.beans.BeansException;

import org.springframework.beans.factory.NoSuchBeanDefinitionException;

import org.springframework.context.ApplicationContext;



public class SpringContextutil {

    private static ApplicationContext context;



    public static ApplicationContext getContext() {

        return context;

    }



    public static void setContext(ApplicationContext context) {

        SpringContextutil.context = context;

    }

    

    public static Object getBean(String name)throws BeansException{

        return context.getBean(name);

    }



    @SuppressWarnings("unchecked")

    public static Object getBean(String name, Class requiredType) throws BeansException {   

        return context.getBean(name, requiredType);   

    }   

  

    public static boolean containsBean(String name) {   

        return context.containsBean(name);   

    }   

  

    public static boolean isSingleton(String name) throws NoSuchBeanDefinitionException {   

        return context.isSingleton(name);   

    }   

  

    @SuppressWarnings("unchecked")

    public static Class getType(String name) throws NoSuchBeanDefinitionException {   

        return context.getType(name);   

    }   

  

    public static String[] getAliases(String name) throws NoSuchBeanDefinitionException {   

        return context.getAliases(name);   

    }   



    

}

5.在WEB.XML里面改变监听为重写的那个类

<listener>

        <listener-class>

            com.ucap.SpringLoaderListener

        </listener-class>

</listener>

 

 

4.获取service 对象。

XzspWebappQuestionService question=(XzspWebappQuestionService)SpringContextutil.getBean("xzspWebappQuestionService");
