바람둥이의 JDBC 영역 구성

Question

SQL Server를 사용하여 인증하도록 tomcat을 구성하려고합니다. 나는 다음과 같이 server.xml을 수정 한 : 나는 lib 폴더에 mssql-jdbc-6.2.1.jre8.jar에 넣어 가지고

SEVERE: Exception performing authentication com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'null'. at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:258) at com.microsoft.sqlserver.jdbc.SQLServerStatement.getNextResult(SQLServerStatement.java:1535) at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.doExecutePreparedStatement(SQLServerPreparedStatement.java:467) at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement$PrepStmtExecCmd.doExecute(SQLServerPreparedStatement.java:409) at com.microsoft.sqlserver.jdbc.TDSCommand.execute(IOBuffer.java:7151) at com.microsoft.sqlserver.jdbc.SQLServerConnection.executeCommand(SQLServerConnection.java:2478) at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeCommand(SQLServerStatement.java:219) at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeStatement(SQLServerStatement.java:199) at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.executeQuery(SQLServerPreparedStatement.java:331) at org.apache.catalina.realm.JDBCRealm.getRoles(JDBCRealm.java:601) at org.apache.catalina.realm.JDBCRealm.authenticate(JDBCRealm.java:404) at org.apache.catalina.realm.JDBCRealm.authenticate(JDBCRealm.java:326) at org.apache.catalina.realm.CombinedRealm.authenticate(CombinedRealm.java:193) at org.apache.catalina.realm.LockOutRealm.authenticate(LockOutRealm.java:158) at org.apache.catalina.authenticator.BasicAuthenticator.authenticate(BasicAuthenticator.java:84) at org.apache.catalina.authenticator.AuthenticatorBase.authenticate(AuthenticatorBase.java:700) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:599) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:140) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:79) at org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:620) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:87) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:349) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:1110) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:785) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1425) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Unknown Source)

: 나는 다음과 같은 오류 매번 얻을 그러나

<Realm className="org.apache.catalina.realm.LockOutRealm"> 
    <!-- This Realm uses the UserDatabase configured in the global JNDI 
     resources under the key "UserDatabase". Any edits 
     that are performed against this UserDatabase are immediately 
     available for use by the Realm. --> 
    <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> 

    <!--This is only applicable for Tomcat 8.5 and higher version with SQL server authentication--> 
     <Realm className="org.apache.catalina.realm.JDBCRealm" 
      driverName="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
    connectionURL="jdbc:sqlserver://xxx.xx.xxx.xxx:1433;databaseName=xxxx" connectionName="user" connectionPassword="password" userTable="xx" userNameCol="username" userCredCol="password"/> 
</Realm> 

내가 인증하려고합니다.

Answer 1

사용자에게 할당 된 역할이있는 테이블이 지정되지 않은 것 같습니다. JDBC 영역에 대한 Tomcat documentation에 따르면 :

:

• There must be a table, referenced below as the user roles table, that contains one row for every valid role that is assigned to a particular user. It is legal for a user to have zero, one, or more than one valid role.
• The user roles table must contain at least two columns (it may contain more if your existing applications required it):
  • Username to be recognized by Tomcat (same value as is specified in the users table).
  • Role name of a valid role associated with this user

예외 스택도 것은 같은 생각을

at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.executeQuery(SQLServerPreparedStatement.java:331) 
at org.apache.catalina.realm.JDBCRealm.getRoles(JDBCRealm.java:601) 
at org.apache.catalina.realm.JDBCRealm.authenticate(JDBCRealm.java:404) 

그래서,이 같은 역할 테이블 userRoleTable 및 역할 이름 열 roleNameCol을 지정해야 이러한 문제를 극복하기을 확인

<Realm className="org.apache.catalina.realm.JDBCRealm" 
     driverName="org.gjt.mm.mysql.Driver" 
     connectionURL="jdbc:mysql://localhost/authority?user=dbuser&amp; 
     password=dbpass" 
     userTable="users" userNameCol="user_name" userCredCol="user_pass" 
     userRoleTable="user_roles" roleNameCol="role_name"/> 

희망 하시겠습니까?
