javax.naming.NameNotFoundException:名称[comp/env]未绑定在此Context中

Question

我正在开发一个使用tomcat服务器管理连接池的spring应用程序.

我在tomcat的context.xml中的tag中定义了数据源:(我使用的是spring 2.0.7)在context.xml中:

<context>
    <Resource name="jdbc/irb_prod"
    auth="Container"
    type="javax.sql.DataSource"
    factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"
    username="xxx"
     password="xxx"
     driverClassName="oracle.jdbc.driver.OracleDriver"
     url="jdbc:oracle:thin:@xxx:1521:xxx"
     maxWait="1000"
     removeAbandoned="true"
     maxActive="5"
     maxIdle="5"
     removeAbandonedTimeout="60"
     logAbandoned="true"/>
</context>

在我的ApplicationContext.xml中(即在spring配置文件中),代码是:

     <bean id="dataSource" 
     class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName">
    <value>java:comp/env/jdbc/irb_prod</value>
    </property>
    </bean>


 <!-- Transaction manager for a single JDBC DataSource -->
    <bean id="transactionManager" 
    class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource"><ref local="dataSource"/></property>
    </bean>

应用程序启动时,我收到以下错误:

请帮我解决这个问题.

Answer 1

我遇到了与tomcat类似的问题,并在eclipse中做了以下事情来解决它:

1. 在服务器的context.xml中,包含了jdbc连接详细信息.
2. 停止服务器
3. 清理项目(Project --> Clean),tomcat服务器(Server--> Right Click --> Clean)和Tomcat工作目录(Server--> Right Click--> Clean Tomcat Work Directory).
4. 启动服务器并运行.

即使在context.xml中维护了细节之后,有时也可能无法反映出来.在这种情况下,请按照步骤#3进行操作并希望有所帮

Answer 2

请web.xml使用类似于以下标签的内容更新您的

<resource-env-ref>
  <description>DataSource
  </description>
  <resource-env-ref-name>
    dbc/irb_prod
  </resource-env-ref-name>
  <resource-env-ref-type>
    javax.sql.DataSource
  </resource-env-ref-type>
</resource-env-ref>
