我正在使用 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>
如果我删除 @ImportResource 我的应用程序启动就好了。我可以连接到 tomcat 实例。我可以检查我所有的执行器端点。使用 JConsole，我可以连接到应用程序，我可以在 MBean 中看到我的数据源（Catalina -> Resource -> Context -> "/" -> localhost -> javax.sql.DataSource -> jdbc/mydatasource）
我还通过 JConsole 在这里显示了 MBean（Tomcat -> DataSource -> / -> localhost -> javax.sql.DataSource -> jdbc/mydatasource）
但是，当我 @ImportResource 实际通过 JNDI 查找 mydatasource 时，并没有找到它。
<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
我在上面配置的 ContextResource 与我在将应用程序部署到 tomcat 容器时部署的 context.xml 中使用的参数完全相同。我导入的 bean 和我的应用程序在部署到 tomcat 容器时工作正常。
所以看起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，但似乎无法在此上下文中生成“comp”绑定。
