Spring bean自定義命名策略，springbean

Spring bean自定義命名策略，springbean

可以直接指定路徑，讓spring掃描包含注解的類

<?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:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="  
    http://www.springframework.org/schema/beans   
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
    http://www.springframework.org/schema/tx   
    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd   
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop.xsd  
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    
    <context:component-scan base-package="com.zhyonk.bean" name-generator="com.zhyonk.framwork.simpleNameGenerator">
        
    </context:component-scan>
    
</beans>

不寫name-generator屬性，默認的命名策略是類名首字母小寫。

protected String buildDefaultBeanName(BeanDefinition definition) {  
        String shortClassName = ClassUtils.getShortName(definition.getBeanClassName());  
        return Introspector.decapitalize(shortClassName);  
    }  

自己可以定義一個generator，需要實現BeanNameGenerator接口

simpleNameGenerator.java

package com.zhyonk.framwork;

import java.beans.Introspector;

import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.beans.factory.support.BeanDefinitionRegistry;
import org.springframework.beans.factory.support.BeanNameGenerator;
import org.springframework.util.ClassUtils;

public class simpleNameGenerator implements BeanNameGenerator {

    public String generateBeanName(BeanDefinition definition,
            BeanDefinitionRegistry registry) {
        System.out.println("BeanDefinition:"+definition.getBeanClassName());

　　　　　　return definition.getBeanClassName(); 

　　} 
}

這樣獲取實體類的時候返回的就是完整的類名了
