ssh中不通过Action如何注入

[danengnai__]

private ServiceImplPublicQuery services = null;

public int getTotalCount() {
   int returnValue = 38;		
   return returnValue;
}

public ServiceImplPublicQuery getServices() {
   return services;
}

public void setServices(ServiceImplPublicQuery services) {
   this.services = services;
}

我通过Flex直接调用了这个方法，但是services总是为空。

回答的这么详细呀，不给分就太说不过去了

lowson0 再问你一下
Constants是什么东西？

[danengnai__]

哦 那个是你自己写的类？

哦,都是一些常用的常量,封装到一个常量类里面了

[如一宝宝]

package com.phoenix.service;

import net.phoenix.comm.AppContext;

public interface IService {
	
	public static AdminInfoService adminInfoService = (AdminInfoService) AppContext.getInstance().getAppContext().getBean("adminInfoTarget");
}

通过一个接口来获取spring的bean,这样就不用action注入了

其中AppContext是spring的上下文的单例类,在服务器启动时加载

这是AppContext的代码

package net.phoenix.comm;

import org.springframework.context.ApplicationContext;

/**
 * 单例类,用于设置,获取Spring上下文的配置信息
 */
public class AppContext {

	private static AppContext instance;
	private static ApplicationContext appContext;

	private AppContext() {

	}

	public synchronized static AppContext getInstance() {
		if (instance == null) {
			instance = new AppContext();
		}
		return instance;
	}

	public static void setContext(ApplicationContext setContext) {
		appContext = setContext;
	}

	public ApplicationContext getAppContext() {
		return appContext;
	}
}

package net.phoenix.listener;

import java.util.HashMap;
import java.util.Map;

import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import net.phoenix.comm.AppContext;
import net.phoenix.comm.Constants;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.web.context.ContextLoaderListener;

/**

 */
public class StartupListener extends ContextLoaderListener implements ServletContextListener {

	private static final Log log = LogFactory.getLog(StartupListener.class);

	/**
	 * 设置程序根目录
	 */
	public void contextInitialized(ServletContextEvent event) {
		String rootpath = event.getServletContext().getRealPath("/");
		if (rootpath != null) {
			rootpath = rootpath.replaceAll("\\\\", "/");
		} else {
			rootpath = "/";
		}
		if (!rootpath.endsWith("/")) {
			rootpath = rootpath + "/";
		}
		Constants.ROOTPATH = rootpath;
		if (log.isDebugEnabled()) {
			log.debug("initializing context...");
		}
		super.contextInitialized(event);

		ServletContext context = event.getServletContext();
		String daoType = context.getInitParameter(Constants.DAO_TYPE);
		if (daoType == null) {
			log.warn("No 'daoType' context carameter, using hibernate");
			daoType = Constants.DAO_TYPE_HIBERNATE;
		}
		Map config = (HashMap) context.getAttribute(Constants.CONFIG);

		if (config == null) {
			config = new HashMap();
		}
		config.put(Constants.DAO_TYPE, daoType);
		context.setAttribute(Constants.CONFIG, config);
		if (log.isDebugEnabled()) {
			log.debug("daoType: " + daoType);
			log.debug("populating drop-downs...");
		}

		setupContext(context);
	}

	// 登录加载spring的context
	public static void setupContext(ServletContext context) {
		ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
		AppContext.setContext(ctx);
		if (log.isDebugEnabled()) {
			log.debug("drop-down initialization complete [OK]");
		}
	}
}

忘了贴上servlet的监听器,在web.xml里面配置下
