是这样的，我新部署了一个springMVC工程，有两个配置文件，application.xml和springServlet-config.xml.<context:component-scan>在springServlet-config.xml里写的，程序成功运行，但是我看网上很多人的博客里的文章的<context:component-scan>标签都在application.xml文件里写的，所以我就将这句话移过去，发现报错了，报了很多Error creating bean with name 'springServlet'，创建不了bean类这种错，请问各位大神，这个标签写的位置有什么其他需要注意的地方吗？

叫什么名字无所谓，看你web.xml怎么配置了

srpingServlet-config.xml是这样配置的：
<?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:task="http://www.springframework.org/schema/task" xmlns:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd "> <!-- 使用默认的注解映射 --> <mvc:annotation-driven /> <!-- <mvc:resources location="/" mapping="/index.html" /> <context:annotation-config></context:annotation-config>--> <!-- world bean类 --> <bean id="world" class="com.entity.World" /> <!-- <property name="user" ref="user" /> <property name="type" value="stringWorld"></property> </bean> --> <bean id="user" class="com.entity.User"/> <!-- user bean类 --> <!-- <bean id="user" class="com.entity.User"> <property name="id" value="1"></property> <property name="name" value="guan"></property> <property name="pwd" value="111111"></property> <property name="age" value="12"></property> </bean> --> <!-- <bean id="world" class="com.entity.World"> <property name="user"> <idref bean="user"/> </property> <property name="type" value="stringWorld"></property> </bean> --> <!-- 自动扫描controller包中的控制器 --> <context:component-scan base-package="com.controller" /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" > <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> <!-- <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="/index.do">controllerDoem</prop> </props> </property> </bean> <bean id="controllerDoem" class="com.controller"> <property name="view"> <value>index</value> </property> </bean>--> </beans>
application.xml是这样配置的：
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!-- <context:component-scan base-package="com.entity" /> --> <!-- <bean id="configProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="locations"> <list> <value>classpath*:META-INF/spring/*.properties</value> </list> </property> </bean> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer"> <property name="properties" ref="configProperties"></property> </bean> 当 Spring 容器启动时，AutowiredAnnotationBeanPostProcessor 将扫描 Spring 容器中所有 Bean，当发现 Bean 中拥有@Autowired 注释时就找到和其匹配（默认按类型匹配）的 Bean，并注入到对应的地方中去。 <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" /> Jpa 事务配置 <bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> jpaVendorAdapter:指定实现JPA的适配器 <bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="showSql" value="true" /> <property name="database" value="${database}" /> <property name="databasePlatform" value="org.hibernate.dialect.MySQLMyISAMDialect" /> </bean> JPA实体管理工厂的配置 <bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory"> <property name="persistenceUnitName" value="persistenceUnit" /> <property name="dataSource" ref="dataSource" /> <property name="jpaVendorAdapter" ref="jpaVendorAdapter" /> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${database.driverClassName}" /> <property name="url" value="${database.url}" /> <property name="username" value="${database.username}" /> <property name="password" value="${database.password}" /> <property name="testOnBorrow" value="true" /> <property name="testOnReturn" value="true" /> <property name="testWhileIdle" value="true" /> <property name="timeBetweenEvictionRunsMillis" value="1800000" /> <property name="numTestsPerEvictionRun" value="3" /> <property name="minEvictableIdleTimeMillis" value="1800000" /> <property name="defaultAutoCommit" value="false" /> </bean> Spring Data Jpa配置 <jpa:repositories base-package="com.zjn.repository" entity-manager-factory-ref="entityManagerFactory"></jpa:repositories> --> </beans>
请问，我把<context:component-scan base-package="com.controller" />写在application里运行就报错，，求大神解答
@坐在家里晒太阳: controller的扫描，放在web.xml中servlet标签里用到的xml里
