java.lang.classnotfoundexception org.springframework.web.context.contextloaderlistener

Question

我有一些麻烦让我的项目工作。我使用Spring，并以我的项目名义看到一个大红色＆＃34;！＆＃34;，并在我的root上下文中看到一些错误：

<bean id="userDao" class="com.goatsoft.appark.dao.UserDaoImpl">
    <property name="dataSource" ref="dataSource" /> //error in this line
</bean>

错误显示＆＃34;找不到属性＆quot; dataSource＆＃39;在课堂上＃com.goatsoft.appark.dao.UserDaoImpl＆＃39;＆＃34;。该类扩展了JdbcDaoSupport，因此它应该是免费的dataSource，如果我没有错的话。

这是dataSource bean定义：

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" /> 
    <property name="url" value="jdbc:mysql://localhost:3306/myDB" /> 
    <property name="username" value="user" /> 
    <property name="password" value="password" /> 
</bean>

当我运行该应用时，即时接收此报告：
