使用JDBCRealm進行基於FORM的認證

Question

我正在實施FORM認證。我在server.xml文件中編輯了領域標記。我也改變了web.xml文件。但是，當我運行Web應用程序，並嘗試連接sql服務器時，引發異常。

我發送了web.xml和server.xml文件的代碼。再加上我試圖獲取數據庫連接的代碼。 server.xml中

<Realm className="org.apache.catalina.realm.JDBCRealm" 

     driverName="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
    connectionURL="jdbc:sqlserver://DESKTOP-ND3EINK\SQLEXPRESS;databaseName=HRSystem;integratedSecurity=true" 
     userTable="HR.users" userNameCol="user_name" userCredCol="user_pass" 
    userRoleTable="HR.user_roles" roleNameCol="role_name"/> 

web.xml中，其中發生異常

static{ 
      try{ 
       Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
       con = DriverManager.getConnection("jdbc:sqlserver://DESKTOP-ND3EINK\\SQLEXPRESS;databaseName=HRSystem;integratedSecurity=true"); 


      } 
catch (Exception e){ 

     e.printStackTrace(); 
    } 
}

而是集成安全的

<display-name>SecurityConstraint</display-name> 

    <web-resource-collection> 
     <web-resource-name>HRPmain</web-resource-name> 
     <url-pattern>/HRPmain.jsp</url-pattern> 
    </web-resource-collection> 

    <auth-constraint> 
     <role-name>HRPersonnel</role-name> 
    </auth-constraint> 

    <user-data-constraint> 
     <transport-guarantee>CONFIDENTIAL</transport-guarantee> 
    </user-data-constraint> 

</security-constraint> 


<login-config> 
    <auth-method> FORM</auth-method> 
    <realm-name>org.apache.catalina.realm.JDBCRealm</realm-name> 
    <form-login-config> 
     <form-login-page>/login2.xhtml</form-login-page> 
     <form-error-page>/error.xhtml</form-error-page> 
    </form-login-config> 
</login-config> 

<security-role> 
    <role-name>HRPersonnel</role-name> 
</security-role> 

代碼，我給了一個用戶名和密碼。它的工作。
