java - Spring/Hibernate配置错误

Question

我是 Java Spring 和 Hibernate 的新手，我正在尝试使用这些技术(Maven、Spring 和 Hibernate)构建应用程序。当我尝试运行它时，我收到来自 glassfish 服务器的错误，这是一个非常长的堆栈跟踪，但这是最后一部分:

Exception while loading the app : java.lang.IllegalStateException:
ContainerBase.addChild: start: org.apache.catalina.LifecycleException:
org.apache.catalina.LifecycleException:
javax.naming.NameNotFoundException: CentricJavaDB not found

我尝试了几个小时，但没有发现我的错误。我很确定它在配置 xml 文件中，但我无法修复它。我希望你们中的一些人可以帮助我(:

配置文件:

WEB-INF 文件夹中的调度程序 servlet:

WEB-INF 中的 glassfish-web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">

 <Resource name="jdbc/CentricJavaDB" auth="Container"

    username="root"
    password="root"
    type="javax.sql.DataSource"
    url="jdbc:mysql://localhost:3306/centricjavadb" />
</glassfish-web-app>

我还找到了这个文件“Other Sources\Setup\glassfish-resources.xml”。我没有看到与“glassfish-web.xml”有很大的区别，但它也包含数据库信息。我认为这也很重要:

</resources>

我认为该错误是由于 jndi-lookup 无法在 glassfish-web.xml 中找到数据源引起的，如果我错了，请纠正我。

我认为这应该是足够的信息。如果您想要更多文件、堆栈跟踪或其他任何内容，请询问，我会发布它。

Answer 1

JNDI 资源通常很难弄清楚。

Stacktrace 指出数据源的定义方式存在问题。根据documentation :

Expect to find the JNDI name of a JDBC resource in java:comp/env/jdbc

尝试将以下内容放入您的配置中:

 <jee:jndi-lookup id="dataSource" jndi-name="java:comp/env/jdbc/CentricJavaDB"/>

虽然根据这个问题:Spring 3 JNDI look up in glassfish3这是没有必要的
