对于static方法，不可直接应用spring注解

public static boolean checkSemiAuto(String jobId, String workId) {String createType;EomAlarmWorkMapper   alarmMapper = ContextUtils.getBean("eomAlarmWorkMapper");EomAlarmWork alarmWork = alarmMapper.selectByPrimaryKey(workId);   if(alarmWork != null && !alarmWork.equals("")){   createType = alarmWork.getCreateType();    }else{   createType = Constants.ALARM_WORK_WEIHU;   }   if(createType.equals(Constants.ALARM_WORK_DEFAULT) && jobId.equals(Constants.JOB_ALARM_HANDLE)){   return true;   }   else{   return false;   }}

不应该用@Autowired

private static EomAlarmWorkMapper alarmWorkMapper;

应为static类加载时候初始化，

package com.ailk.utils;import org.apache.commons.lang3.Validate;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.DisposableBean;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;/** * 以静态变量保存Spring ApplicationContext,  */public class ContextUtils implements ApplicationContextAware, DisposableBean {private static ApplicationContext applicationContext = null;private static PropertiesLoader propertiesLoader;private static Logger logger = LoggerFactory.getLogger(ContextUtils.class);public static String getConfig(String key) {if (propertiesLoader == null){propertiesLoader = new PropertiesLoader("config.properties");}return propertiesLoader.getProperty(key);}/** * 取得存储在静态变量中的ApplicationContext. */public static ApplicationContext getApplicationContext() {assertContextInjected();return applicationContext;}/** * 从静态变量applicationContext中取得Bean, 自动转型为所赋值对象的类型. */@SuppressWarnings("unchecked")public static <T> T getBean(String name) {assertContextInjected();return (T) applicationContext.getBean(name);}/** * 从静态变量applicationContext中取得Bean, 自动转型为所赋值对象的类型. */public static <T> T getBean(Class<T> requiredType) {assertContextInjected();return applicationContext.getBean(requiredType);}/** * 清除ContextUtils中的ApplicationContext为Null. */public static void clearHolder() {logger.debug("清除ContextUtils中的ApplicationContext:"+ applicationContext);applicationContext = null;}/** * 实现ApplicationContextAware接口, 注入Context到静态变量中. */@Overridepublic void setApplicationContext(ApplicationContext applicationContext) {if (ContextUtils.applicationContext != null) {logger.warn("ContextUtils中的ApplicationContext被覆盖, 原有ApplicationContext为:" + ContextUtils.applicationContext);}ContextUtils.applicationContext = applicationContext; // NOSONAR}/** * 实现DisposableBean接口, 在Context关闭时清理静态变量. */@Overridepublic void destroy() throws Exception {ContextUtils.clearHolder();}/** * 检查ApplicationContext不为空. */private static void assertContextInjected() {Validate.validState(applicationContext != null, "applicaitonContext属性未注入, 请在applicationContext.xml中定义ContextUtils");}}
