Spring框架之InitializingBean接口

引用参考：
--Spring提供的InitializingBean接口初始化bean
https://www.cnblogs.com/study-everyday/p/6257127.html
1、提供一个类，实现InitializingBean接口

import org.springframework.beans.factory.InitializingBean;
import mbp.gateway.web.msgcontent.content.BaseContent;

public class StudentBean implements InitializingBean{
	/**
	 * 重写InitializingBean提供的afterPropertiesSet方法
	 */
	@Override
	public void afterPropertiesSet() throws Exception {
		System.out.println("初始化StudentBean=");
	}
	/**
	 * 自定义初始化方法
	 */
	public void initBean(){
		System.out.println("测试init-method 初始化bean StudentBean");
	}
}

2、Spring的bean配置文件

    
<bean name="studentBean " class="com.demo.bean.StudentBean " init-method="initBean">
		<property name="targetMaps">
			<map>
				<entry key="Grade1">
					<map>
						<entry key="c1,c2,c3,c4">
							<ref bean="commonClassContent" />
						</entry>
					</map>
				</entry>
			</map>
		</property>
	</bean>
	<bean name="commonClassContent" class="com.demo.bean.CommonClassContent" />

3、测试类

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class Demo {
	public static void main(String[] args) {
		ApplicationContext context=new FileSystemXmlApplicationContext("/src/main/resources/com/demo/baseContent.xml");
		System.out.println("context="+context);
	}
}
