SampleBean:
package com.springexample;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
public class SampleBean {
private BeanTypeOne beanOne;
private BeanTypeTwo beanTwo;
public void init() {
System.out.println("This is from the init() method");
}
@PostConstruct
public void initAnnotation() {
System.out.println("This is from the initAnnotation() method");
}
和配置文件如下:
<bean id="SampleBean" class="com.springexample.SampleBean">
<property name="beanOne" ref="beanOneOne"></property>
<property name="beanTwo" ref="beanTwoOne"></property>
</bean>
我没有在 beans 标记上设置 default-init-method 属性。< / p>
任何正文都可以告诉为什么@PostConstruct方法不会被调用。

您需要<context:annotation-config/>
(或<context:component-scan/>
)才能启用@PostConstruct
处理。
