多线程中获取bean对象

https://blog.youkuaiyun.com/qq_38493490/article/details/80431321

 

注：多线程场景下，使用默认的spring自动装配无法获取bean对象，此方案可以从context上下文中直接获取bean。

1、创建类，实现ApplicationContextAware接口；

package com.bond.match.utils;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

/**

 * Date: 2018/1/11 0011
 * Time: 13:20

 */
@Component
public class ApplicationContextProvider implements ApplicationContextAware {
    private static ApplicationContext context;

    private ApplicationContextProvider(){}

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        context = applicationContext;
    }

    public  static <T> T getBean(Class<T> aClass){
        return context.getBean(aClass);
    }
}
2、多线程中的调用方式: .method()是bean对象的方法名称

ApplicationContextProvider.getBean(AccountAssetService.class).method()
