多线程时Autowired自动注入问题

在多线程时使用@Autowired总是获取不到bean，原因是：new thread不在spring容器中，也就无法获得spring中的bean对象。

解决方法：手动获取

package com.zuikc.web.controller;

import com.zuikc.dao.user.bean.User;
import com.zuikc.dao.user.mappers.IUserMapper;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
@RequestMapping("/app")
public class GetApplicationController implements ApplicationContextAware {

    private static ApplicationContext applicationContext;//springMVC上下文定义
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        GetApplicationController.applicationContext=applicationContext;
    }
    public static ApplicationContext getApplicationContext(){
        return GetApplicationController.applicationContext;
    }
    public static<T> T getBean(String name)throws BeansException{
        return (T)applicationContext.getBean(name);
    }

    @RequestMapping("getapp")
    public String GetAPP(){
        IUserMapper userMapper = applicationContext.getBean(IUserMapper.class);
        List<User> list = userMapper.GetAll();

        String a="11";
        return  "hello";
        /*SpringApplicationContext.getApplicationContext().getBean(CategoryMapper.class)*/
    }

}

　　

 

　　

  

在其他service里调用

ThreadFactory namedThreadFactory = new ThreadFactoryBuilder().setNameFormat("upFinancial-pool-%d").build();
            ExecutorService pool = new ThreadPoolExecutor(corePoolSize, maxPoolSize,
                    6000L, TimeUnit.MILLISECONDS,
                    new LinkedBlockingDeque<Runnable>(1024), namedThreadFactory, new ThreadPoolExecutor.AbortPolicy());
            UpFinancialContractHandler handler=new UpFinancialContractHandler();
            handler.setUser(user);
            pool.execute(handler);
