java 获取spring配置文件中bean 对象

Posted 2022-12-11 Django_1987

编写工具类：

package com.thunisoft.webservice.service.util;


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

public class getBean implements ApplicationContextAware

private static ApplicationContext  app;

public void setApplicationContext(ApplicationContext applicationContext)  throws BeanException

this.app = applicationContext;

public static ApplicationContext getYouBean()

return app;

applicationContext 配置文件：

<bean id = "applicationContext" class="com.thunisoft.webservice.service.util.getBean"> 

操作类：

可以写在方法的构造方法中。

public test()

try

ApplicationContext  app = getBean.getYouBean();

fydao=(IFydao)app.getBean("fydao");

catch(Exception e)

log.error("工具类获取application中bean对象失败！",e);
