spring 自动装配 default-autowire="byName/byType"一、spring 自动装配 default-autowire="byName"byName,按变量名称，与id名称一样，若不一样，就报错。<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="" xmlns:xsi="" xmlns:aop="" xmlns:tx="" xsi:schemaLocation=" http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"default-autowire="byName"><bean id="bean1" class="com.zd.bean.Bean1" > <!– 配了default-autowire="byName" ,可以注释<property name="bean2"><ref bean="bean2" /></property><property name="bean3" ref="bean3" /><property name="bean4"><bean class="com.zd.bean.Bean4"><property name="age" value="16" /></bean></property> –> </bean>二、spring 自动装配 default-autowire="byType"byType，，按类型自动装配，若变量与id不匹配，也没关系<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="" xmlns:xsi="" xmlns:aop="" xmlns:tx="" xsi:schemaLocation=" http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"default-autowire="byName"><bean id="bean1" class="com.zd.bean.Bean1" > <!– 配了default-autowire="byType" ,可以注释<property name="bean2"><ref bean="bean2" /></property><property name="bean3" ref="bean3" /><property name="bean4"><bean class="com.zd.bean.Bean4"><property name="age" value="16" /></bean></property> –> </bean>三、默认配置是no，推荐用这种，因以上自动装配，对维护不是太好。
