當在(tomcat 7)server.xml或Context.xml中配置數據源時,hibernate無法識別JNDI並在低於默認值時拋出,但在嘗試訪問時正常工作正常數據源在代碼中使用JNDI。我究竟做錯了Tomcat 7.0中的數據源JNDI配置Hibernate
下面是我在hibernate.properties
hibernate.connection.driver_class com.mysql.jdbc.Driver
hibernate.connection.pool_size 10
hibernate.dialect org.hibernate.dialect.MySQL5Dialect
hibernate.connection.datasource java:comp/env/jdbc/employee
hibernate.show_sql true
hibernate.format_sql true
在server.xml配置
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<!-- SingleSignOn valve, share authentication between web applications
Documentation at: /docs/config/valve.html -->
<!--
<Valve className="org.apache.catalina.authenticator.SingleSignOn" />
-->
<!-- Access log processes all example.
Documentation at: /docs/config/valve.html
Note: The pattern used is equivalent to using pattern="common" -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log." suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" resolveHosts="false"/>
**<Context docBase="hibernate" path="/hibernate">
<Resource name="jdbc/employee" auth="Container"
type="javax.sql.DataSource" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:45000/hibernatetest"
username="user" password="hibernate" maxActive="20" maxIdle="10"
maxWait="-1" removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true"/>
</Context>**
</Host>
在context.xml的最後文件如下
**<Context docBase="hibernate" path="/hibernate">
<Resource name="jdbc/employee" auth="Container"
type="javax.sql.DataSource" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:45000/hibernatetest"
username="user" password="hibernate" maxActive="20" maxIdle="10"
maxWait="-1" removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true"/>
</Context>**
是我的web.xml文件
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
**<web-app >

</web-app>**
org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [java:comp/env/jdbc/employee]
採取出server.xml中的全部。另外,當你說「context.xml」時,你的意思是你的webapp中的META-INF/context.xml,還是你的意思是Tomcat的全局conf/context.xml? –
