在Spring MVC中，Controller中使用service只需使用注解@Resource或者@Persist就行，但是一般类（即不使用@Controller注解的类）要用到service时，可用如下方法：

     1、SpringContextUtil

package com.test.framework.utils;import org.springframework.beans.BeansException;import org.springframework.beans.factory.NoSuchBeanDefinitionException;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;public class SpringContextUtil implements ApplicationContextAware {	private static ApplicationContext applicationContext; // Spring应用上下文环境	// 下面的这个方法上加了@Override注解，原因是继承ApplicationContextAware接口是必须实现的方法	@Override	public void setApplicationContext(ApplicationContext applicationContext)			throws BeansException {		SpringContextUtil.applicationContext = applicationContext;	}	public static ApplicationContext getApplicationContext() {		return applicationContext;	}	public static Object getBean(String name) throws BeansException {		return applicationContext.getBean(name);	}	public static Object getBean(String name, Class requiredType)			throws BeansException {		return applicationContext.getBean(name, requiredType);	}	public static boolean containsBean(String name) {		return applicationContext.containsBean(name);	}	public static boolean isSingleton(String name) throws NoSuchBeanDefinitionException {		return applicationContext.isSingleton(name);	}	public static Class getType(String name)	throws NoSuchBeanDefinitionException {		return applicationContext.getType(name);	}	public static String[] getAliases(String name) throws NoSuchBeanDefinitionException {		return applicationContext.getAliases(name);	}}

       2、Spring的配置文件application.xml中进行如下配置

<bean id="SpringContextUtil" class="com.cnpc.framework.utils.SpringContextUtil"  scope="singleton"/>

        3、使用
       

DictService dictService = (DictService) SpringContextUtil.getBean("dictService");List<Dict> dict = (List<Dict>) dictService.findByHQL(hql);

Spring MVC中一般类使用service
