javax.naming.NameNotFoundException : Name [jdbc/spitterDS] is not bound in this Context. 无法找到 [jdbc]

Question

我正在尝试使用 Spring 的 jee jndi-lookup 标记访问 tomcat 中的 JNDI datasource。

异常表明我没有正确注册我的数据源，但我无法弄清楚为什么不正确。

这是我的代码:-

service-context.xml:-

<?xml version="1.0" encoding="UTF-8"?>

    <context:component-scan base-package="spitter" />
    <mvc:annotation-driven />

    <jee:jndi-lookup id="dataSource" jndi-name="/jdbc/spitterDS" resource-ref="true" />

</beans>

webapp/META-INF/context.xml:-

<Context path="/spitter" reloadable="true" cachingAllowed="false" antiResourceLocking="true">

<!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>

<Resource name="jdbc/spitterDS" auth="Container" type="org.apache.commons.dbcp.BasicDataSource"
    maxActive="100" maxIdle="30" maxWait="10000" username="root" password="password"
    driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/spitter" />
</Context>

web.xml:-

</servlet>

<servlet-mapping>

</servlet-mapping>

</web-app>

最后，

MainController.java:-

package spitter.mvc;

import java.sql.Connection;
import java.sql.SQLException;

import javax.annotation.Resource;
import javax.sql.DataSource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;


@Controller
@RequestMapping("/")
public class MainController {
    @Resource(name="dataSource")
    private DataSource dataSource;

    @RequestMapping(method = RequestMethod.GET)
    public String showHome(Model model) throws SQLException{
        Connection con = dataSource.getConnection();

        return "spitter";
    }
}

我在 Eclipse kepler 中为 JEE 开发人员使用 Tomcat 7。当我在 eclipse 中启动 tomcat 服务器时出现异常:-

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mainController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource': Invocation of init method failed; nested exception is javax.naming.NameNotFoundException: Name [jdbc/spitterDS] is not bound in this Context. Unable to find [jdbc].

我假设我在某个地方打错了字，但找不到它。请帮忙!

Answer 1

"/jdbc/spitterDS" 不等于 "jdbc/spitterDS"。

在service-context.xml文件中，
改变

<jee:jndi-lookup id="dataSource" jndi-name="/jdbc/spitterDS" resource-ref="true" />

到

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/spitterDS" resource-ref="true" />

编辑:

Error creating bean with name 'dataSource':

根据文档:

... in the @Resource(name="jdbc/Foo") DataSource ds; annotation, the global JNDI name is jdbc/Foo.
...
The @Resource annotation in the application code looks like this:
@Resource(name="jdbc/helloDbDs") javax.sql.DataSource ds;

改变:

@Resource(name="dataSource")
private DataSource dataSource;

收件人:

@Resource(name="jdbc/spitterDS")
private DataSource dataSource;
