解决多线程无法通过@Autowired注入实例bean

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

//解决多线程 无法通过@Autowired注入bean
@Component
public class ApplicationContextPro implements ApplicationContextAware {
    //上下文对象实例
    private static ApplicationContext applicationContext; //applicationContext
    //生成get和set方法
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
    }
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }
    /**
     * 通过name获取 Bean.
     */
    public static Object getBean(String name) {
        return getApplicationContext().getBean(name);
    }
    /**
     * 通过class获取Bean
     */
    public static <T> T getBean(Class<T> clazz) {
        return getApplicationContext().getBean(clazz);
    }
    /**
     * 通过name,以及Clazz返回指定的Bean
     */
    public static <T> T getBean(String name, Class<T> clazz) {
        return getApplicationContext().getBean(name, clazz);
    }
}

 

	@Autowired 
	private CsdnUrlService csdnUrlService = ApplicationContextPro.getBean(CsdnUrlService.class);  //注意这里的参数的接口

这里通过构造去调用所需要的方法
