为什么initMethod没有执行 ？

[yjhengineer]

尝试搭建struts2+spring的框架集成，配置如下：

web.xml：

<filter>
	  	<filter-name>struts2</filter-name>
	  	<filter-class>
	  		org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
	  	</filter-class>
	  </filter>
	  <filter-mapping>
	  	<filter-name>struts2</filter-name>
	  	<url-pattern>/*</url-pattern>
	  </filter-mapping>
	  <listener>
      	 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	  </listener>
	  <context-param>
       <param-name>contextConfigLocation</param-name>
	  <param-value>classpath*:applicationContext.xml</param-value>

applicationContext.xml：

<bean name="loginService" class="com.ssh.service.LoginService" init-method="initMethod" scope="prototype">
	</bean>

service代码：

public class LoginService implements InitializingBean {
	
	@Override
	public void afterPropertiesSet() throws Exception {
		System.out.println("service afterPropertiesSet method");
	} 
	
	public void initMethod(){
		System.out.println("service initMethod method");
	}
	
	

}

tomcat启动后没有执行相关代码：

是不是哪里配置有问题啊 ？？

没人遇到过这种问题吗 ？

启动tomcat的时候当然不会去调用afterPropertiesSet回调方法和initMethod初始方法了 , 你这个bean是scope="prototype", 只有在每次使用的时候在去ioc容器拿这个bean的时候才会执行初始化方法, tomcat启动的时候, 容器也会启动, 但是scope="prototype"不会再这个时候初始化bean, 更谈不上执行初始化方法了

二楼说的好有道理，受教了，那如果配置scope="singleton"呢 ？这个什么时候会被加载？
