【问题描述】：

安装“keycloak-12.0.4”后。我能够在默认的 keycloak H2 数据库上成功运行服务器。但是，当我尝试添加 POSTGRESQL“数据源”时，出现连接错误。

以下是我采取的步骤：

我在 Docker 上运行了一个 POSTGRESQL 数据库服务器

docker run -d -p 5432:5432 --name postgres-keycloak --restart unless-stopped -e "DB_TYPE=postgres" -e "DB_HOST=hs-psql13-prod" -e "DB_PORT=5432" - e "DB_USER=keycloak_user" -e "DB_PASS=MyPassword" -e "DB_NAME=keycloak_dev" emanoid/postgres

接下来我在“keycloak-12.0.4/modules/system/layers/keycloak/org”目录中添加了一个空白的“postgresql/main/module.xml”文件 然后我从https://jdbc.postgresql.org/download.html 下载了一个JDBC postgres 驱动程序。我专门下载了postgresql-42.2.19。这个驱动也被放到了“keycloak-12.0.4/modules/system/layers/keycloak/org/postgresql/main/”目录下。 我使用以下详细信息更新了“module.xml”文件：

<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.3" name="org.postgresql">
    <resources>
        <resource-root path="postgresql-42.2.19.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
    </dependencies>
</module>

为了声明和加载我的 JDBC 驱动程序，我转到“keycloak-12.0.4/standalone/configuration/standalone.xml”文件并将以下配置添加到相应的标签中：

<drivers>
    <driver name="postgresql" module="org.postgresql">
        <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
    </driver>
    <driver name="h2" module="com.h2database.h2">
        <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
    </driver>
</drivers>

<datasource jndi-name="java:jboss/datasources/KeycloakDS" pool-name="KeycloakDS" enabled="true" use-java-context="true"> 
    <connection-url>jdbc:postgresql://hs-psql13-prod/5432/keycloak_dev</connection-url>
    <driver>postgresql</driver>
    <pool>
        <max-pool-size>20</max-pool-size>
    </pool>
    <security>
        <user-name>keycloak_user</user-name>
         <password>MyPassword</password>
    </security>
</datasource>

<spi name="connectionsJpa">
    <provider name="default" enabled="true">
        <properties>
            <property name="dataSource" value="java:jboss/datasources/KeycloakDS"/>
            <property name="initializeEmpty" value="false"/>
            <property name="migrationStrategy" value="manual"/>
            <property name="migrationExport" value="$jboss.home.dir/keycloak-database-update.sql"/>
        </properties>
    </provider>
</spi>

接下来，我通过导航到“keycloak-12.0.4/bin/”和standalone.bat -Djboss.socket.binding.port-offset=100 来运行服务器，让服务器在端口 8180 上运行。

采取这些步骤后：这是终端错误消息：

我已尝试以下方法来解决此问题：

使用默认 H2 数据库运行服务器 - 效果很好 下载其他 JDBC 驱动程序 - 产生类似错误 确保 Postgres 数据库正在运行SQL Shell Database Listing

我期待任何有助于解决此问题的贡献。我的 *** 浏览、Google 搜索和在线论坛推荐无助于解决此问题。谢谢！

【参考方案1】：

要解决该错误，应更新“standalone.xml”文件。具体来说，名称为 connectionsJpa 的“spi”标签应该从

更新

<spi name="connectionsJpa">
    <provider name="default" enabled="true">
        <properties>
            <property name="dataSource" value="java:jboss/datasources/KeycloakDS"/>
            <property name="initializeEmpty" value="false"/>
            <property name="migrationStrategy" value="manual"/>
            <property name="migrationExport" value="$jboss.home.dir/keycloak-database-update.sql"/>
        </properties>
    </provider>
</spi>

到

<spi name="connectionsJpa">
    <provider name="default" enabled="true">
        <properties>
            <property name="dataSource" value="java:jboss/datasources/KeycloakDS"/>
            <property name="initializeEmpty" value="false"/>
            <property name="migrationStrategy" value="update"/>
            <property name="migrationExport" value="$jboss.home.dir/keycloak-database-update.sql"/>
        </properties>
    </provider>
</spi>

这是因为，使用手动时，脚本希望您手动运行某个 SQL 配置文件，否则可以通过将值参数从“手动”更改为“更新”来自动运行。

更新此文档后，我能够将 keycloak 连接到我的数据库！我希望这对任何人都有帮助！
