spring - 找不到类 [org.springframework.jdbc.datasource.DriverManagerDataSourc[

Question

好的，log4j 和 servlet 错误已得到修复。现在我有以下问题:

找不到类 [org.springframework.jdbc.datasource.DriverManagerDataSourc

我当前的 web.xml 如下所示:

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
         http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">


 <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>

 <!--
  <listener>
  <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
 </listener>
  -->

 <!-- Register and setup my servlet xml files here -->

 <servlet>
  <servlet-name>appStore</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
   <param-name>contextConfigLocation</param-name>
   <param-value></param-value>
  </init-param>
 </servlet>

 <servlet-mapping>
  <servlet-name>appStore</servlet-name>
  <url-pattern>*.htm</url-pattern>
 </servlet-mapping>

 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
   /WEB-INF/zang-file-service.xml
  </param-value>
 </context-param>

</web-app>

zang-file-service.xml 如下:

<beans xmlns="ht..p://www.springframework.org/schema/beans"

 <!-- h..p://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.0.xsd -->

 <!-- Config properties files -->

 <!-- Hibernate database stuff -->

 </bean>


 <bean id="dataSource1"

  <property name="url" value="${database.url}" />
  <property name="username" value="${database.user}" />
  <property name="password" value="${database.password}" />
  <property name="maxActive" value="${database.maxConnections}" />
 </bean>


 <!-- LocalSessionFactoryBean u need to put the hbm files in the WEB-INF/classes 
  root director -->

 <bean id="sessionFactory"
  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  <property name="dataSource" ref="dataSource1"></property>
  <property name="mappingResources">
   <list>
    <value>FileObject.hbm.xml</value>
   </list>
  </property>
  <property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
    <prop key="hibernate.show_sql">true</prop>
    <prop key="hibernate.hbm2ddl.auto">create</prop>
   </props>
  </property>
 </bean>


 <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
  <property name="sessionsFactory" ref="sessionFactory"></property>
 </bean>

 <bean id="fileDownload" class="com.kc.models.FileManipulator">
  <property name="dbTemplate" ref="hibernateTemplate"></property>
 </bean>

</beans>

编辑:这是我的 jdbc/properties 文件

# DB properties file

database.url=jdbc:mysql://localhost:3306/zangshop
database.driver=com.mysql.jdbc.Driver
database.user=XXXX
database.password=XXXX
database.maxConnections=25

编辑:来自 tomcat 的完整错误

你错过了类名中的最后一个字母。应该是:

class="org.springframework.jdbc.datasource.DriverManagerDataSource"

为了对 spring 配置进行一些编译时验证，您可以尝试 SpringSource Tool Suite (STS)
