运行springmvc那个例子的时候报的错

mistbow

下面这个错误需要怎么修改呢？我已经在tomcat配置过jndi了。
这个错误是在启动tomcat的时候报出的。
程序的还是可以运行的。

use test;
create table testuser (
       userId           char(20) not null,
       name             varchar(20) null,
       PRIMARY KEY  (userId)
);
INSERT INTO testuser VALUES ('1', 'tony');
INSERT INTO testuser VALUES ('2', 'sunny');
INSERT INTO testuser VALUES ('3', 'kevin');

Tomcat的JDNI配置：


<Context path="" debug="5" reloadable="true" crossContext="true">
  <Resource name="jdbc/TestDS" auth="Container" type="javax.sql.DataSource"
               maxActive="100" maxIdle="30" maxWait="10000"
               username="root" password="" driverClassName="com.mysql.jdbc.Driver"
               url="jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=UTF-8&amp;autoReconnect=true"/>

</Context>

jndi这个我已经配置了 但是还是有那个错误 我的配置如下：
server.xml:
<Resource name="jdbc/DataSource" auth="Container"
type="javax.sql.DataSource" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/test"
username="root" password="root" maxActive="20" maxIdle="10"
maxWait="-1"/>

context.xml:

<ResourceLink name="jdbc/simplejdbc" global="jdbc/DataSource" type="javax.sql.DataSource"/>

然后您的web.xml是这样子的：
<resource-ref>
<res-ref-name>jdbc/simplejdbc</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

这几个地方配置的应该没问题吧？

2012年02月01日 10:48 "@mistbow"的内容
jdbc/DataSource ...

和web.xml无关，server.xml和context.xml中只要配置一项即可，无需两个都配。

程序中使用的JNDI名称是： java:comp/env/jdbc/TestDS

java:comp/env是JavaEE规定前缀，去除这个前缀，就是jdbc/TestDS，这是Resource名称，在Server.xml或context.xml中的Resource名称name值也要是jdbc/TestDS。

注意两个resource中的name值要一样，这称为映射mapping，是你的应用程序和tomcat之间接口名称映射，需要一样。

而你是jdbc/DataSource，改为jdbc/TestDS即可。
