startup failed due to previous errors

在使用SSH添加

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

 

tomcat在启动的时候发生如下错误： 

2008-9-28 11:13:01 org.apache.catalina.core.StandardContext start
严重: Error listenerStart
2008-9-28 11:13:01 org.apache.catalina.core.StandardContext start
严重: Context [/xxfire] startup failed due to previous errors

 

 

错误分析：

 

      错误触发在web.xml中定义

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/context/ApplicationContext-*.xml</param-value>
</context-param>
<SPAN style="COLOR: #000000"><listener>
        <listener-class><SPAN style="BACKGROUND-COLOR: #ff6600">org.springframework.web.context.ContextLoaderListener</SPAN></listener-class>
</listener></SPAN>

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/context/ApplicationContext-*.xml</param-value>
</context-param>
<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

   检查spring配置管理xml文件。发现错误产生在：

 

<bean id="dataSource" class="<SPAN style="COLOR: #000000; BACKGROUND-COLOR: #ff6600">org.apache.commons.dbcp.BasicDataSource</SPAN>">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
    <property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl"></property>
    <property name="username" value="sys8"></property>
    <property name="password" value="sys8"></property>
</bean>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
	<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
	<property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl"></property>
	<property name="username" value="sys8"></property>
	<property name="password" value="sys8"></property>
</bean>

   上面所示的代码中，红色代码是产生错误的根源，在spring管理Hibernate的dataSource是用的是：

<SPAN style="COLOR: #000000">org.springframework.jdbc.datasource.DriverManagerDataSource</SPAN>

org.springframework.jdbc.datasource.DriverManagerDataSource

 

解决：

<bean id="dataSource" class="<SPAN style="BACKGROUND-COLOR: #ff6600">org.springframework.jdbc.datasource.DriverManagerDataSource</SPAN>">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
    <property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl"></property>
    <property name="username" value="sys8"></property>
    <property name="password" value="sys8"></property>
</bean>
