Spring bean自定义命名策略

本文内容纲要:Spring bean自定义命名策略

可以直接指定路径,让spring扫描包含注解的类

<?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>

不写name-generator属性,默认的命名策略是类名首字母小写。

protected String buildDefaultBeanName(BeanDefinition definition) {  

String shortClassName = ClassUtils.getShortName(definition.getBeanClassName());

return Introspector.decapitalize(shortClassName);

}

自己可以定义一个generator,需要实现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();

  }

}

这样获取实体类的时候返回的就是完整的类名了
