spring - Spring无法使用Tomcat提供的JNDI DataSource？

Question

我想在基于 Spring 的应用程序中使用 Tomcat 提供的 JNDI 数据源。我使用 Tomcat 7 池。尝试按照 here 所述进行配置。

配置Tomcat的server.xml:

  <GlobalNamingResources>
    <Resource name="jdbc/ApsuserAtAzistst"
              auth="Container"
              type="org.apache.tomcat.jdbc.pool.DataSource"
              driverClassName="oracle.jdbc.OracleDriver"
              url="jdbc:oracle:thin:@10.0.153.10:1525:AZISTST"
              username="APSUSER"
              password="PASSWORDOFAPSUSER"
              initialSize="1"
              minIdle="1"
              maxIdle="1"
              maxActive="3"
              maxWait="1000"
              validationQuery="select 1 from dual"
              jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer;org.apache.tomcat.jdbc.pool.interceptor.SlowQueryReport(threshold=1500)"
            />
  </GlobalNamingResources>

创建了 META-INF\context.xml 内容:

<?xml version="1.0" encoding="UTF-8"?>
<Context>
    <ResourceLink name="jdbc/ApsuserAtAzistst"
                  global="jdbc/ApsuserAtAzistst"
                  type="org.apache.tomcat.jdbc.pool.DataSource"/>
</Context>

和配置的applicationContext.xml

<beans profile="dev,test,default">
    <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName" value="java:comp/env/jdbc/ApsuserAtAzistst"/>
    </bean>
</beans>

当我运行应用程序时，我收到一个错误:

SEVERE: Exception processing Global JNDI Resources

当我将 applicationContext.xml 更改为:

<beans profile="dev,test,default">
    <bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
        <property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
        <property name="url" value="jdbc:oracle:thin:@10.0.153.10:1525:AZISTST"/>
        <property name="username" value="APSUSER"/>
        <property name="password" value="PASSWORDOFAPSUSER"/>
        <property name="initialSize" value="1"/>
        <property name="minIdle" value="1"/>
        <property name="maxIdle" value="1"/>
        <property name="maxActive" value="3"/>
        <property name="maxWait" value="1000"/>
        <property name="validationQuery" value="select 1 from dual"/>
        <property name="jdbcInterceptors"
                  value="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer;org.apache.tomcat.jdbc.pool.interceptor.SlowQueryReport(threshold=1500)"/>
    </bean>
</beans>

但是我想在Tomcat中配置JNDI DataSource并使用它。

Answer 1

原因是，我错过了 factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"。资源的正确定义必须是

  <GlobalNamingResources>
    <Resource name="jdbc/ApsuserAtAzistst"
              auth="Container"
              type="javax.sql.DataSource"
              factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
              driverClassName="oracle.jdbc.OracleDriver"
              url="jdbc:oracle:thin:@10.0.153.10:1525:AZISTST"
              username="APSUSER"
              password="PASSWORDOFAPSUSER"
              initialSize="1"
              minIdle="1"
              maxIdle="1"
              maxActive="3"
              maxWait="1000"
              validationQuery="select 1 from dual"
              jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer;org.apache.tomcat.jdbc.pool.interceptor.SlowQueryReport(threshold=1500)"
            />
  </GlobalNamingResources>
