1.在spring中,先执行属性配置,在执行afterPropertySet()方法，最后init()方法
2.配置文件改为
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
?<bean id="test" class="test.Test"?init-method="init">
??<property name="name">
???<value>chenhaibin</value>
??</property>
?</bean>
</beans>
3.在Test中增加一个init方法
package test;
import org.springframework.beans.factory.InitializingBean;
public class Test implements InitializingBean
{
?private String name;
?
?public String getName()
?{
??return name;
?}
?public void setName(String name)
?{
??System.out.println("-----------setName-------");
??this.name = name;
?}
?public void afterPropertiesSet() throws Exception
?{
??System.out.println("--------afterPropertyiesSet---------");
?}
?
?public void init() throws Exception
?{
??System.out.println("--------init---------");
?}
}
4.测试结果是
2007-08-16 15:39:00,549 DEBUG [org.springframework.beans.CachedIntrospectionResults] - <Found property 'class' of type [java.lang.Class]>
2007-08-16 15:39:00,549 DEBUG [org.springframework.beans.CachedIntrospectionResults] - <Found property 'name' of type [java.lang.String]>
