使用 postgresql 連接到 Wildfly 上的數據庫時出現問題

Question

我在使用 postgresql 連接到 Wildfly 上的數據庫時遇到問題，我在 Red Hat Core Studio 中編寫。
我的 standalone.xml 是：

<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}}">

              </security>
          </datasource>
          <datasource jndi-name="java:jboss/datasources/tvTutorial" pool-name="tvTutorial" enabled="true" statistics-enabled="true">
               <connection-url>jdbc:postgresql//localhost:5432/tvTutorial</connection-url>

           <validation>
               <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLValidConnectionChecker"/>

            </datasource>

                <driver name="h2" module="com.h2database.h2">

                </driver>
            </drivers>
        </datasources>
    </subsystem>
...
    </deployment>
    </deployments>
</server>

我的 persistence.xml 是：

<!DOCTYPE xml>

        </properties>
    </persistence-unit>
</persistence>

當我go在wildfly HAL管理

console/configuration/subsystems/datasources&drivers/JDBC Drivers/

我看到兩個 JDBC 驅動程序：

"NewPestsList-1.0.war"和"NewPestsList-1.0.war_org.postgresql.Driver_42_2"如圖兩個war文件我的日志是：

我覺得這與此有關，但由於我是編程新手，我不確定是否應該添加更多數據，請告訴我。

編輯：我在 stdunbar 和 Will T 的幫助下更新了我的程序。仍然需要學習如何重新安裝 Wildfly。 現在我收到這些警告和錯誤：

編輯#2：

我在<jta-data-source>jdbc/tvTutorial</jta-data-source>中寫了正確的地址后就可以了 謝謝你們

Answer 1

潛水員必須作為模塊添加，你不能引用你的戰爭部署

本指南適用於 mysql，但過程相同，只是使用正確的名稱

Answer 2

您正在創建數據源和JDBC 連接。 你真的只想要數據源。 因此，與其采取手動步驟修改 standalone.xml 並安裝模塊，我推薦一種更標准、更不容易出錯的方法。 您可以通過提供 JDBC 驅動程序的副本來編寫整個過程的腳本。

創建一個包含如下代碼的腳本：

embed-server --server-config=standalone.xml --std-out=echo

batch

# add the module
module add --name=org.postgres --resources=/path/to/postgresql-42.2.8.jar --dependencies=javax.api,javax.transaction.api

# add the driver
/subsystem=datasources/jdbc-driver=postgres:add(driver-name="postgres",driver-module-name="org.postgres",driver-class-name=org.postgresql.Driver)

# add the datasource
/subsystem=datasources/data-source=tvTutorial/:add(connection-url=jdbc:postgresql://localhost:5432/tvTutorial,driver-name=postgres,jndi-name=java:/jdbc/tvTutorial,user-name=user,password=password)

run-batch

然后運行它：

$WILDFLY_HOME/bin/jboss-cli.sh --file=the_file_name.cli

（請注意，$WILDFLY_HOME 可能未設置。它只是您安裝 Wildfly 的目錄）

假設您的服務當前未運行。 如果它正在運行，則刪除前兩行和最后一行。

您的persistence.xml文件現在非常簡單，因為配置全部在standalone.xml中通過數據源：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
             http://xmlns.jcp.org/xml/ns/persistence/persistence_2_2.xsd"
             version="2.2">
    <persistence-unit name="tvTutorialPU" transaction-type="JTA">
        <jta-data-source>jdbc/tvTutorial</jta-data-source>
    </persistence-unit>
</persistence>

這給你的是一個可重復的過程。 您現在不必手動修改standalone.xml文件，如果您升級我在 Wildfly 8.x 到 18.x 上使用了相同的腳本。

我會從全新安裝的 Wildfly 開始，因為您不知道所有的東西都被損壞了。
