获得spring上下文ApplicationContext

 

在项目中实现 ApplicationContextAware 的接口，并且将实现类注册成为组件 @Component ，就能得到spring的上下文ApplicationContext。

 

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

/**
 * @ClassName: ApplicationContextProvider
 * @author kanpiaoxue
 * @version 1.0
 * @CreateTime: 2019/04/12 12:01:39
 * @Description: 
 */
@Component
public class ApplicationContextProvider implements ApplicationContextAware {
    private static ApplicationContext applicationContext;

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    /*
     * (non-Javadoc)
     * @see
     * org.springframework.context.ApplicationContextAware#setApplicationContext
     * (org.springframework.context.ApplicationContext)
     */
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        ApplicationContextProvider.applicationContext = applicationContext;

    }

}

 

使用：

ApplicationContext applicationContext = ApplicationContextProvider.getApplicationContext();
