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);
}
}
</div>
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) {
}
}
</div>
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);
}
}
</div>
