在Spring中没有调用@PostConstruct方法

Question

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.

任何人都可以告诉为什么@PostConstruct方法不会被调用.

Answer 1

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