apache tomcat 7.0.30 datasourcerealm javax.naming.NameNotFoundException:名称[jdbc/proto]未绑定在此Context中.找不到[jdbc]

Question

让我先描述一下环境:

环境: - mac os x(java build 1.6.0_35-b10-428-11M3811) - apache tomcat 7.0.30 - mysql 5.5.27 - tomcat/lib - > mysql-connector-java-5.1.22-bin.jar

我已成功实现了JDBCRealm并希望切换到DataSourceRealm,因为它建议用于生产环境.我使用基于表单的身份验证.

我做了这里描述的所有内容:http: //tomcat.apache.org/tomcat-7.0-doc/realm-howto.html#DataSourceRealm 和这里:http: //tomcat.apache.org/tomcat-7.0-doc/jndi-数据源-例子,howto.html#MySQL_DBCP_Example

server.xml中

<Realm className="org.apache.catalina.realm.LockOutRealm">
     <Realm className="org.apache.catalina.realm.DataSourceRealm" 
            dataSourceName="jdbc/proto" digest="SHA-256" roleNameCol="role" 
            userCredCol="password" userNameCol="name" userRoleTable="roles" 
            userTable="users"/>
</Realm>

的context.xml

<Resource auth="Container" 
          driverClassName="com.mysql.jdbc.Driver" 
          maxActive="100" maxIdle="30" maxWait="10000" 
          name="jdbc/proto" password="proto" type="javax.sql.DataSource" 
          url="jdbc:mysql://localhost:3306/proto" username="proto"/>

WEB-INF/web.xml文件

<resource-ref>
    <description>DB Connection</description>
    <res-ref-name>jdbc/proto</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

当我提交用户名和密码时,我得到以下例外:

Sep 18, 2012 9:38:32 PM org.apache.catalina.realm.DataSourceRealm open

我没有尝试在不同的操作系统上设置环境来测试它是否是特定于mac的问题.

我错过了什么建议？我感谢您的帮助!谢谢.

Answer 1

为避免在GlobalNamingResources中声明资源，请将localDataSource =“ true”放入领域

Answer 2

就我而言，问题是我的 pom.xml 中存在冲突的依赖关系。就我而言，这就是java-naming依赖性。确保您没有任何与 Tomcat 的命名库冲突的命名依赖项/jar。

删除它后，问题就消失了（顺便说一句，与您的环境相同）。
