【问题描述】：

我正在尝试在 Wildfly 18 和 SQL Server 2017 之间建立连接。我已将驱动程序 mssql-jdbc-7.2.2.jre11.jar 添加到路径 C:\wildfly-18.0.0.Final\modules\system\layers\base\com\microsoft\sqlserver\main。在同一个文件夹中，我添加了一个 module.xml 文件，其内容如下：

<module xmlns="urn:jboss:module:1.3" name="com.microsoft.sqlserver">
    <resources>
        <resource-root path="mssql-jdbc-7.2.2.jre11.jar" />
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
    </dependencies>
</module>

在C:\wildfly-18.0.0.Final\standalone\configuration\standalone.xml 文件中我有下一个：

<datasources>
    <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true" statistics-enabled="$wildfly.datasources.statistics-enabled:$wildfly.statistics-enabled:false">
        <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
        <driver>h2</driver>
        <security>
            <user-name>sa</user-name>
            <password>sa</password>
        </security>
    </datasource>
    <datasource jndi-name="java:/MSSQLDS" pool-name="MSSQLDS">

        <driver>sqlserver</driver>

        <validation>
            <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mssql.MSSQLValidConnectionChecker"/>
            <background-validation>true</background-validation>
        </validation>
    </datasource>
    <drivers>
        <driver name="h2" module="com.h2database.h2">
            <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
        </driver>
        <driver name="sqlserver" module="com.microsoft.sqlserver">
            <driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class>
        </driver>
    </drivers>
</datasources>

我从 HAL 控制台添加了数据源。但是，在 HAL 控制台中测试连接时出现此错误：

"WFLYJCA0040: failed to invoke operation: WFLYJCA0047: Connection is not valid"

最后，在server.log 文件中我得到了这个异常：

从 MS SQL Server Management Studio，我可以使用 xpression 用户连接到 xpresscr 数据库。我不知道为什么我无法从 Wildfly 连接。有什么帮助吗？

谢谢！！

【问题讨论】：

无法打开登录请求的数据库“xpresscr”。登录失败。 您的计算机上是否安装了多个版本/实例的 SQL Server？ 127.0.0.1:1433 将尝试连接到“默认”实例，通常称为 MSSQLSERVER。

嗨@AlwaysLearning，感谢您的回复。这是一台新的 Windows 机器。我刚刚安装了 SQL Server 2017。我只创建了一个数据库，添加了一个用户并更改了一些设置。

在 SQL Server [2017] 配置管理器 > SQL Server 网络配置 > MSSQLSERVER 的协议中是否启用了 TCP/IP 协议？是否配置为侦听 127.0.0.1 端口 1433？注意：如果您在此处更改设置，则需要重新启动 SQL Server 服务才能使更改生效。

嗨@AlwaysLearning，TCP/IP 协议已启用。在其属性中，在“IP 地址”选项卡中，我有四个“IP + 号码”和一个“IPAll”。 “IP4”的 IP 地址为 127.0.0.1。其余的“IP+号码”有不同的IP地址。所有这些“IP + 号码”设置都处于活动状态，但未启用。

以前没有注意到这一点，SQLServerException: 无法打开登录请求的数据库“xpresscr”。登录失败。这表明它能够建立 TCP 连接，但是还没有发生一些安全配置/用户映射。尝试在 SQL Server ERRORLOG 文件中查看登录失败事件 18456，然后将状态编号与 MSSQLSERVER_18456 进行比较，以了解 SQL Server 认为问题所在。

【参考方案1】：

确保您的 SQL SERVER 正在侦听 1433 端口：

2。如果是这样，您的连接字符串可能无效，请尝试 以下格式的连接字符串： sqlserver://username:password@host:port?database=dbname 即sqlserver://sa:123@127.0.0.1:1433?database=xpresscr
