spring随手笔记2：初始化方法

1.init-method="init"

public class HelloWorldServiceImpl implements HelloWorldService {

    private String msg;

    public void init(){
        this.msg="hellword";
    }
    public void setMsg(String msg) {
        this.msg = msg;
    }
    public String getMsg() {
        return msg;
    }
}

<bean id="HelloWorld" class="com.ltf.captha.serviceImpl.HelloWorldServiceImpl" init-method="init">
        <property name="msg">
            <value>helloworld</value>
        </property>
    </bean>

2.实现org.springframework.beans.factory.InitializingBean中的afterPropertiesSet

public class HelloWord implements InitializingBean{
    private String msg;
    public void setMsg(String msg) {
        this.msg = msg;
    }
    public String getMsg() {
        return msg;
    }
    public void afterPropertiesSet() throws Exception {
        this.msg="hello";
    }

}
