1、定义上下文工具类：

package com.alimama.config;import org.springframework.context.ApplicationContext;/** * 上下文获取工具类 * @author mengfeiyang * */public class SpringContextUtil { private static ApplicationContext applicationContext; public static void setApplicationContext(ApplicationContext context) { applicationContext = context; } public static Object getBean(String beanId) { return applicationContext.getBean(beanId); }}

2、在启动入口类中注入applicationContext

package com.alimama;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;import org.springframework.boot.context.properties.EnableConfigurationProperties;import org.springframework.context.ApplicationContext;import org.springframework.context.annotation.ComponentScan;import com.alimama.config.SbootConfig;import com.alimama.config.SpringContextUtil;import com.alimama.config.ZKConfig;import com.alimama.quartz.InitTask;/** * spring boot启动入口类 * @author mengfeiyang * */@ComponentScan@SpringBootApplication@EnableConfigurationProperties({ZKConfig.class,SbootConfig.class})public class SbootApplication implements EmbeddedServletContainerCustomizer{ public static void main(String[] args) { ApplicationContext applicationContext = SpringApplication.run(SbootApplication.class, args); SpringContextUtil.setApplicationContext(applicationContext); } @Override public void customize(ConfigurableEmbeddedServletContainer container) { }}

3、调用方法

package com.alimama.quartz;import java.io.IOException;import org.phoenix.api.action.IInterfaceAPI;import org.phoenix.api.action.InterfaceAPI;import org.quartz.Job;import org.springframework.beans.factory.annotation.Autowired;import com.alimama.config.SpringContextUtil;import com.alimama.dto.TaskBean;import com.alimama.service.IConfigService;import com.alimama.service.impl.ConfigService;/** * 任务执行者 * */public class TaskHandler implements Job{ private ConfigService configService = (ConfigService) SpringContextUtil.getBean("configService"); private IInterfaceAPI interf = new InterfaceAPI(); @Override public void execute(JobExecutionContext arg0){ String watchDogServer = configService.getwatchDogServer(); System.out.println(watchDogServer); }}
