项目中所有的spring输入都是通过注解注入，在spring配置中配置自动扫描路径，现在遇到如下问题： 此时我的spring扫描应该如何配置才可以两个包路径下的都可以扫描？ <context:component-scan base-package="com" use-default-filters="false"> <context:include-filter type="regex" expression=".*aaa.*" /> <context:include-filter type="regex" expression=".*ccc.*" /> </context:component-scan> 表达式里面改成com.aaa.*和com.bbb.*结果也是不行，报错如下： org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: URL [jar:file:/E:/tomcat/apache-tomcat-7.0.53-default/wtpwebapps/serverPay/WEB-INF/lib/icu4j-2.6.1.jar!/com/ibm/icu/impl/data/LocaleElements_zh__PINYIN.class]; nested exception is java.lang.ArrayIndexOutOfBoundsException: 48188 at org.springframework.context.annotation.ClassPathScanningCandidateComponentProvider.findCandidateComponents(ClassPathScanningCandidateComponentProvider.java:290) at org.springframework.context.annotation.ClassPathBeanDefinitionScanner.doScan(ClassPathBeanDefinitionScanner.java:242) at org.springframework.context.annotation.ComponentScanBeanDefinitionParser.parse(ComponentScanBeanDefinitionParser.java:84) at org.springframework.beans.factory.xml.NamespaceHandlerSupport.parse(NamespaceHandlerSupport.java:73) at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDelegate.java:1438) at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDelegate.java:1428) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.parseBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:195) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.doRegisterBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:139) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.registerBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:108) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.registerBeanDefinitions(XmlBeanDefinitionReader.java:493) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:390) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:334) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:302) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:174) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:209) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:180) at org.springframework.web.context.support.XmlWebApplicationContext.loadBeanDefinitions(XmlWebApplicationContext.java:125) at org.springframework.web.context.support.XmlWebApplicationContext.loadBeanDefinitions(XmlWebApplicationContext.java:94) at org.springframework.context.support.AbstractRefreshableApplicationContext.refreshBeanFactory(AbstractRefreshableApplicationContext.java:130) at org.springframework.context.support.AbstractApplicationContext.obtainFreshBeanFactory(AbstractApplicationContext.java:537) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:451) at org.springframework.web.context.ContextLoader.configureAndRefreshWebApplicationContext(ContextLoader.java:389) at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:294) at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:112) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4973) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5467) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1559) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1549) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) |

<context:component-scan base-package="com.*"/> 试试这样行么？ |
 |
这样也试过，也是不行，错误也是上面我贴出来的错。 |
|
有可能是他引入注解的jar和你引入的jar冲突了。 |
|
不是jar包冲突问题，我自己单独起了个项目，新建了两个不同的包结构，用spring注解注入，也是不行 |
|
新建一个也不行？怪事啊 |

这样的高级用法，还没有用过呢
|
|
是不行的，你可以自己新建个项目试试，给两个或多个不同结构的包进行注入。 |

<context:component-scan base-package="com" use-default-filters="false"> <context:include-filter type="regex" expression="com.aaa.bbb.*" /> <context:include-filter type="regex" expression="com.ccc.ddd.*" /> </context:component-scan> 这样呢 |

我试了一下写成 <context:component-scan base-package="com.aaa.bbb.*"/> <context:component-scan base-package="com.ccc.ddd.*"/> 和 <context:component-scan base-package="com.*"/> 都是可以的啊 |
