详解在SpringBoot应用中获取应用上下文方法

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);
 }
}
