spring 解决多线程或者非bean类中使用bean对象

获取spring对象的工具类

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Configuration;

import java.util.Locale;

@Configuration
public class SpringContextUtil implements ApplicationContextAware {
 private static ApplicationContext context;
 @Override
 public void setApplicationContext(ApplicationContext contex)throws BeansException { SpringContextUtil.context = contex;}
 public static ApplicationContext getApplicationContext() {
   return context; 
 } 
 public static Object getBean(String beanName) {
  return context.getBean(beanName);
 }
 public static String getMessage(String key) {
  return context.getMessage(key, null, Locale.getDefault());
 }
}

在类中声明bean对象

private Common common;

赋值

 if (common == null)  common = (Common) SpringContextUtil.getBean("common");
