Question

我已经在tomcat 5.5上部署了我的应用程序，IDE是eclipse with myeclipse插件。当我尝试启动tomcat服务器时，我收到以下错误：

错误 - ContextLoader.initWebApplicationContext（219）|上下文初始化失败 org.springframework.beans.factory.BeanCreationException：在ServletContext资源[/WEB-INF/xaconfig/daoJPAConfig.xml]中定义了名为'dataSource'的bean创建错误：init方法的调用失败;嵌套异常是javax.naming.NameNotFoundException：名称java：comp未绑定在此Context中在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFactory.java:1412）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean（AbstractAutowireCapableBeanFactory.java:519）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean（AbstractAutowireCapableBeanFactory.java:456） at org.springframework.beans.factory.support.AbstractBeanFactory $ 1.getObject（AbstractBeanFactory.java:291）在org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton（DefaultSingletonBeanRegistry.java:222）在org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean（AbstractBeanFactory.java:288）在org.springframework.beans.factory.support.AbstractBeanFactory.getBean（AbstractBeanFactory.java:190）在org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons（DefaultListableBeanFactory.java:546）在org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization（AbstractApplicationContext.java:871）在org.springframework.context.support.AbstractApplicationContext.refresh（AbstractApplicationContext.java:423）在org.springframework.web.context.ContextLoader.createWebApplicationContext（ContextLoader.java:272）在org.springframework.web.context.ContextLoader.initWebApplicationContext（ContextLoader.java:196）在org.springframework.web.context.ContextLoaderListener.contextInitialized（ContextLoaderListener.java:47） at org.apache.catalina.core.StandardContext.listenerStart（StandardContext.java:3669）在org.apache.catalina.core.StandardContext.start（StandardContext.java:4104）在org.apache.catalina.core.ContainerBase.start（ContainerBase.java:1012）在org.apache.catalina.core.StandardHost.start（StandardHost.java:718）在org.apache.catalina.core.ContainerBase.start（ContainerBase.java:1012）在org.apache.catalina.core.StandardEngine.start（StandardEngine.java:442）在org.apache.catalina.core.StandardService.start（StandardService.java:450）在org.apache.catalina.core.StandardServer.start（StandardServer.java:683）在org.apache.catalina.startup.Catalina.start（Catalina.java:537） at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method） at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:39） at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:25）在java.lang.reflect.Method.invoke（Method.java:597）在org.apache.catalina.startup.Bootstrap.start（Bootstrap.java:271）在org.apache.catalina.startup.Bootstrap.main（Bootstrap.java:409）引发者：javax.naming.NameNotFoundException：名称java：comp未绑定在此Context中在org.apache.naming.NamingContext.lookup（NamingContext.java:778）在org.apache.naming.NamingContext.lookup（NamingContext.java:161）在javax.naming.InitialContext.lookup（InitialContext.java:392）在org.springframework.jndi.JndiTemplate $ 1.doInContext（JndiTemplate.java:154）在org.springframework.jndi.JndiTemplate.execute（JndiTemplate.java:87）在org.springframework.jndi.JndiTemplate.lookup（JndiTemplate.java:152）在org.springframework.jndi.JndiTemplate.lookup（JndiTemplate.java:178）在org.springframework.jndi.JndiLocatorSupport.lookup（JndiLocatorSupport.java:95）在org.springframework.jndi.JndiObjectLocator.lookup（JndiObjectLocator.java:105）在org.springframework.jndi.JndiObjectFactoryBean.lookupWithFallback（JndiObjectFactoryBean.java:201）在org.springframework.jndi.JndiObjectFactoryBean.afterPropertiesSet（JndiObjectFactoryBean.java:187）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods（AbstractAutowireCapableBeanFactory.java:1469）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFactory.java:1409） ......还有27个

我已将Apache Software Foundation \ Tomcat 5.5 \ conf中的数据源配置为：

  <GlobalNamingResources>
    <Environment
      name="simpleValue"
      type="java.lang.Integer"
      value="30"/>
    <Resource
      name="jdbc/Paymentsdb"
      type="javax.sql.DataSource"
      maxActive="20"
      maxIdle="10"
      username="root"
      maxWait="20000"
      validationQuery="SELECT=1"
      driverClassName="com.mysql.jdbc.Driver"
      password="root"
      url="jdbc\:mysql\://devserver\:3306/payhub"/>
    <Resource
      auth="Container"
      description="User database that can be updated and saved"
      name="UserDatabase"
      type="org.apache.catalina.UserDatabase"
      factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
      pathname="conf/tomcat-users.xml"/>
  </GlobalNamingResources>

我添加了Apache Software Foundation \ Tomcat 5.5 \ conf \ context.xml页面我添加了我的webInf \ web.xml

 <resource-ref>
   <description>PaymentsDatabase</description>
   <res-ref-name>jdbc/Paymentsdb</res-ref-name>
   <res-type>javax.sql.DataSource</res-type>
   <res-auth>Container</res-auth>
</resource-ref>

我正在使用spring框架，hybernate + jpa。请告诉我，问题可能是什么？

Answer 1

我不建议将其放在Tomcat的全局配置中。无法保证您可以访问它。最好把它放在META-INF / context.xml中。

您没有显示JNDI数据源的Spring配置。请加上。

嵌套异常是 javax.naming.NameNotFoundException：名称java：comp未绑定在此上下文

这不应该是java:comp/env吗？

Spring无法查找jdbc配置的数据源
