1. 方法上加注解@PostConstruct

@Compant

public class InitDemo{

@PostConstruct

public void init(){

//项目启动就会执行这个方法

doSomething();

}

}

2.xml配置init-method

<bean id="InitDemo" class="com.xxx.InitDemo" scope="singleton" init-method="init">

</bean>

3.实现InitializingBean接口,重写afterPropertiesSet方法

@Component

public class InitDemo implements InitializingBean {

@Override

public void afterPropertiesSet() throws Exception {

//doSomeThing

}
