我使用的是Spring Boot，并尝试使用为我的数据源创建JNDI上下文的嵌入式tomcat启动：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
        <version>1.1.4.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <version>1.1.4.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-oracle</artifactId>
        <version>1.0.0.RELEASE</version>
    </dependency>

如果删除@ImportResource，我的应用程序将启动。我可以连接到tomcat实例。我可以检查所有执行器端点。使用JConsole，我可以连接到应用程序，并且可以在MBean中看到我的数据源（Catalina->资源->上下文->“
/”-> localhost-> javax.sql.DataSource-> jdbc / mydatasource）

我还通过JConsole在此处显示了MBean（Tomcat-> DataSource-> /-> localhost->
javax.sql.DataSource-> jdbc / mydatasource）

但是，当我@ImportResource时，实际上是通过JNDI查找mydatasource的，但找不到它。

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

我导入的xml文件的相关部分

我上面配置的ContextResource具有与在将应用程序部署到tomcat容器中时要部署的context.xml中使用的参数完全相同的参数。导入到tomcat容器后，导入的Bean和应用程序可以正常工作。

因此看来我现在有一个上下文，但似乎命名不正确。我尝试了资源名称的各种组合，但似乎无法在这种情况下生成“ comp”绑定。
