Spring的init-method 与afterPropertiesSet

博客分类:

init-method 与afterPropertiesSet 都是在初始化bean的时候执行,执行顺序是afterPropertiesSet 先执行,init-method 后执行,afterPropertiesSet 必须实现 InitializingBean接口

今天遇到一问题,在配置文件中配置了init-method

<bean id="financeAgent" class="com.sumavision.ecommerce.plateform.core.monitor.FinanceAgent"

init-method="initialize" destroy-method="destroy">

<property name="jmsTemplate" ref="jmsTemplate" />

<property name="serviceMap">

<map

value-type="com.sumavision.ecommerce.plateform.core.monitor.FinanceMonitorService">

<entry key="financeManageService"

value-ref="financeManageService" />

<entry key="financeTransactService"

value-ref="financeTransactService" />

</map>

</property>

</bean>

<!-- Jndi -->

<bean id="jndiTemplate"

class="org.springframework.jndi.JndiTemplate">

<property name="environment">

<props>

<prop key="java.naming.factory.initial">

weblogic.jndi.WLInitialContextFactory

</prop>

<prop key="java.naming.provider.url">

t3://192.166.68.44:7001

</prop>

<prop key="java.naming.factory.url.pkgs">

weblogic.jndi.factories

</prop>

</props>

</property>

</bean>

<!-- jms sender -->

<bean id="jmsConnectionFactory"

class="org.springframework.jndi.JndiObjectFactoryBean">

<property name="jndiTemplate" ref="jndiTemplate" />

<property name="jndiName" value="ConnectionFactory" />

</bean>

<bean id="jmsQueue"

class="org.springframework.jndi.JndiObjectFactoryBean">

<property name="jndiTemplate" ref="jndiTemplate"></property>

<property name="jndiName" value="Queue"></property>

</bean>

<!-- jms template -->

<bean id="jmsTemplate"

class="org.springframework.jms.core.JmsTemplate">

<property name="connectionFactory" ref="jmsConnectionFactory"></property>

<property name="defaultDestination" ref="jmsQueue"></property>

</bean>

在加载的时候不能执行,找了半天最后发现是因为

<beans default-lazy-init="true"></beans> 配置了延迟初始化,但是有的bean的init-method是可以运行的,具体需要再看下这个

<bean id="tradeAuditService"

class="com.sumavision.ecommerce.plateform.core.audit.impl.TradeAuditServiceImpl"

init-method="initialize">

<property name="auditRuleDAO" ref="AuditRuleDAO"></property>

<property name="negativelyTradeDAO" ref="NegativelyTradeDAO"></property>

<property name="securityServiceManager"

ref="securityServiceManager">

</property>

</bean>

<bean id="tradeAuditServiceProxy" parent="baseTransactionProxy">

<property name="target" ref="tradeAuditService"></property>

<property name="transactionAttributes">

<props>

<prop key="process">

PROPAGATION_REQUIRED,ISOLATION_SERIALIZABLE

</prop>

</props>

</property>

</bean>

这个就起作用了,


通过Spring @PostConstruct 和 @PreDestroy 方法 实现初始化和销毁bean之前进行的操作

关于在spring 容器初始化 bean 和销毁前所做的操作定义方式有三种:

第一种:通过@PostConstruct 和 @PreDestroy 方法 实现初始化和销毁bean之前进行的操作

第二种是:通过 在xml中定义init-method 和 destory-method方法

第三种是: 通过bean实现InitializingBean和 DisposableBean接口

下面演示通过 @PostConstruct 和 @PreDestory

1:定义相关的实现类:

[java] view
plaincopy

package com.myapp.core.annotation.init;

import javax.annotation.PostConstruct;

import javax.annotation.PreDestroy;

public class PersonService {

private String message;

public String getMessage() {

return message;

}

public void setMessage(String message) {

this.message = message;

}

@PostConstruct

public void init(){

System.out.println("I'm init method using @PostConstrut...."+message);

}

@PreDestroy

public void dostory(){

System.out.println("I'm destory method using @PreDestroy....."+message);

}

}

2:定义相关的配置文件:

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">
<!-- <context:component-scan base-package="com.myapp.core.jsr330"/> -->

<context:annotation-config />

<bean id="personService" class="com.myapp.core.annotation.init.PersonService">

<property name="message" value="123"></property>

</bean>

</beans>

其中<context:annotation-config />告诉spring 容器采用注解配置:扫描注解配置;

测试类:

[java] view
plaincopy

package com.myapp.core.annotation.init;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MainTest {

public static void main(String[] args) {

ApplicationContext context = new ClassPathXmlApplicationContext("resource/annotation.xml");

PersonService personService = (PersonService)context.getBean("personService");

personService.dostory();

}

}

测试结果:

I'm init method using @PostConstrut....123

I'm destory method using @PreDestroy.....123

其中也可以通过申明加载org.springframework.context.annotation.CommonAnnotationBeanPostProcessor

类来告诉Spring容器采用的 常用 注解配置的方式:

只需要修改配置文件为:

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">
<!-- <context:component-scan base-package="com.myapp.core.jsr330"/> -->

<!-- <context:annotation-config /> -->

<bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor" />

<bean id="personService" class="com.myapp.core.annotation.init.PersonService">

<property name="message" value="123"></property>

</bean>

</beans>

同样可以得到以上测试的输出结果。
