一、在xml中引入xml，用<import>
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:c="http://www.springframework.org/schema/c" 5 xsi:schemaLocation="http://www.springframework.org/schema/beans 6 http://www.springframework.org/schema/beans/spring-beans.xsd"> 7 www.it-ebooks.info 8 62 C HAPTER 2 Wiring beans 9 <import resource="cd-config.xml" /> 10 <bean id="cdPlayer" 11 class="soundsystem.CDPlayer" 12 c:cd-ref="compactDisc" /> 13 </beans>
二、在xml中引入java配置,用<bean>
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:c="http://www.springframework.org/schema/c" 5 xsi:schemaLocation="http://www.springframework.org/schema/beans 6 http://www.springframework.org/schema/beans/spring-beans.xsd"> 7 <bean class="soundsystem.CDConfig" /> 8 <bean id="cdPlayer" 9 class="soundsystem.CDPlayer" 10 c:cd-ref="compactDisc" /> 11 </beans>
或新建一个文件，引入所有配置文件，不管是xml还是java
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:c="http://www.springframework.org/schema/c" 5 xsi:schemaLocation="http://www.springframework.org/schema/beans 6 http://www.springframework.org/schema/beans/spring-beans.xsd"> 7 <bean class="soundsystem.CDConfig" /> 8 <import resource="cdplayer-config.xml" /> 9 </beans>
Whether I’m using JavaConfig or XML wiring, I often create a root configuration, as I’ve
shown here, that brings together two or more wiring classes and/or XML files. It’s in
this root configuration that I’ll also usually turn on component scanning (with either
<context:component-scan> or @ComponentScan )
