我发现了一些将 validationQuery =“ select 1” 添加到context.xml的解决方案。但是在我的context.xml中，我没有资源。

<Context>
<!-- Authenticate against PlanonRealmLogin (JAAS) -->
<!--   allRolesMode=authOnly" means that no role is needed for '*' requirement -->
<Realm appName="PlanonRealmLogin" 
    className="org.apache.catalina.realm.JAASRealm"
    userClassNames="nl.planon.cerebeus.PnUser" 
    roleClassNames="nl.planon.cerebeus.PnRole"
    allRolesMode="authOnly"/>

<!--Valve className="nl.planon.tomcat.AccessKeyValve" throttle="5000"/-->

<!--Valve className="nl.planon.tomcat.ForgotPasswordLoginValve"/-->

<!-- Will force authentication attempts to be parsed as UTF-8. The Landingpage will prevent HTTP 408 messages
    because now, even without a stored original location, Tomcat knows where to forward to. -->
    <!-- exceptionAttributeName="PnLoginException"--> 
<Valve className="nl.planon.tomcat.PnMessageFormAuthenticator" landingPage="/" characterEncoding="utf-8"/>

<!-- This valve excludes valid webdav users with role webdav_readwrite to enter the web application(s) -->
<!--Valve className="nl.planon.tomcat.ExcludingRoleValve"/-->

<!--Parameter name="trustedServiceKeystore" value="${catalina.home}/webclientKeystore.jks" />
<Parameter name="trustedServiceName" value="webclient" /-->

<Manager pathname="" />

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

<!-- Whitelist the minimal set of HTTP Methods that Web Bootstrap needs -->
<!--Valve className="nl.planon.owasp.valve.WhitelistHTTPMethodsValve" methods="GET, OPTIONS, HEAD, POST, PUT, DELETE" /-->

在我的server.xml中，我提到了资源。

  <GlobalNamingResources>
<!-- Editable user database that can also be used by
     UserDatabaseRealm to authenticate users
-->
<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 name="jdbc/PlanonDS"
  auth="Container"
  type="javax.sql.DataSource"
  username=""
  password=""
  driverClassName="net.sourceforge.jtds.jdbc.Driver"
  url="jdbc:jtds:sqlserver://SZH1DB;instance=planon"
  validationQuery="select 1"
  maxActive="8"
  maxIdle="4"/>

在这里我使用了 validationQuery =“ select 1” 。但是我仍然遇到同样的错误。

有人可以帮助我解决这个错误吗？

Tomcat 8中的AbstractMethodError
