我试图使用Spring的jee jndi-lookup标签访问tomcat中的JNDI数据源.

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这样做.

这是我的代码： –

服务的context.xml： –

    <mvc:annotation-driven />

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

</beans>

Web应用程序/ META-INF / context.xml中： –

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

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

</Context>

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.我在eclipse中启动tomcat服务器时的异常： –

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].

我想我在某个地方做了一个错字但却找不到它.请帮忙！

解决方法:

“/ jdbc / spitterDS”不等于“jdbc / spitterDS”.

在service-context.xml文件中,
更改

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

至

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

编辑：

Error creating bean with name ‘dataSource’:

根据文件：

… 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;

更改：

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

至：

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