Question

我正在尝试使用Derby网络数据库保护Tomcat的管理员访问权限。为此，我创建了一个具有所有必要的Derby网络数据库。

这是我的server.xml

<?xml version="1.0" encoding="UTF-8"?>

  <Server port="8005" shutdown="SHUTDOWN">
  <!-- Security listener. Documentation at /docs/config/listeners.html
  <Listener className="org.apache.catalina.security.SecurityListener" />
  -->
  <!--APR library loader. Documentation at /docs/apr.html -->
  <Listener SSLEngine="on" className="org.apache.catalina.core.AprLifecycleListener"/>
  <!--Initialize Jasper prior to webapps are loaded. Documentation at /docs/jasper-howto.html -->
  <Listener className="org.apache.catalina.core.JasperListener"/>
  <!-- Prevent memory leaks due to use of particular java/javax APIs-->
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener"/>
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"/>
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener"/>

  <GlobalNamingResources>

    <Resource auth="Container" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" name="UserDatabase" pathname="conf/tomcat-users.xml" type="org.apache.catalina.UserDatabase"/>

    <Resource auth="Container" driverClassName="org.apache.derby.jdbc.ClientDriver" factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory" maxActive="20" maxIdle="10" name="jdbc/***" password="***" readOnly="false" type="javax.sql.DataSource" url="jdbc:derby://localhost:1527//***" username="***" validationQuery="SELECT count(*) FROM users"/>

  </GlobalNamingResources>

  <Service name="Catalina">

    <Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/>

    <Engine defaultHost="localhost" name="Catalina">

           via a brute-force attack -->
      <Realm className="org.apache.catalina.realm.DataSourceRealm" dataSourceName="jdbc/***" debug="0" digest="MD5" roleNameCol="ROLENAME" userCredCol="PASSWORD" userNameCol="USERNAME" userRoleTable="***" userTable="USERS"/>

        <Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">


        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log." suffix=".txt"/>

      <Context docBase="***" path="***" reloadable="true" source="org.eclipse.jst.jee.server:tds"/></Host>
    </Engine>
  </Service>
</Server>

我的context.xml：

<?xml version="1.0" encoding="UTF-8"?>
  <Context>
    <WatchedResource>WEB-INF/web.xml</WatchedResource>

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

derbyclient.jar，derbynet.jar，derby.jar位于$ Tomcat目录$ / libs

当我初始化tomcat时，一切似乎都没问题但是如果我尝试访问管理器它会返回以下错误：

ene 26, 2015 4:58:56 PM org.apache.catalina.realm.DataSourceRealm open
SEVERE: Exception performing authentication

也许缺少了什么？我不知道我做错了什么，因为我在生产服务器上检查了一个类似的配置，没有区别。很明显，Derby网络DB已初始化（我可以用松鼠打开它）

我很感激任何贡献

编辑：

嘿伙计们，配置还可以，但我在资源网址jdbc中遇到错误：derby：// localhost：1527 // C：*** \ derbydb - ＆gt; JDBC：德比：//本地主机：1527 / C：*** \ derbydb

希望我的配置对某人有用
