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
