帶有數據源的 Wildfly 配置

Question

這是我第一次嘗試在 Wildfly 服務器中設置數據源。 我嘗試按照我在 Google 上找到的一些教程進行操作，但仍然無效。

我正在開發一個 Web 服務，但在部署 .war 文件時我不斷收到一些錯誤。

這是部署應用程序時的最新日志：

Answer 1

進入您的 wildfly 控制台（類似於 localhost:9990）並編輯 Configuration->Container->EE->Default Bindings 部分。 將默認數據源設置為某個有效數據源的 JNDI 名稱。

我刪除了那里的默認值，並將其指向我的主數據源，因為該服務器僅用於運行一個應用程序。

Answer 2

您的 standalone.xml xmlns "urn:jboss:domain:datasources:2.0" 部分中可能缺少 ds 聲明 "java:jboss/datasources/ExampleDS"，它會起作用（這是默認配置中的示例）：

            <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
                <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>
            <drivers>
                <driver name="h2" module="com.h2database.h2">
                    <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                </driver>
            </drivers>

或者您也可以通過其他響應提到的 UI 添加。

Answer 3

你能發布你的數據源定義嗎？

我認為最好測試數據源部署“獨立”。 我的意思是與實際應用程序部署分開，只是為了測試您的數據源是否有效。 您可以使用 Web 控制台 (localhost:9990/console) 測試此 fi。

看起來wildfly的預配置示例DS也存在問題。 您是否刪除了此 DS？ 在standalone.xml 中還有一個對ExampleDS 的引用，它可能被破壞了。

Answer 4

假設您使用的是 MySQL DB，您可以通過以下方式創建 DS：

(1) 從這里下載 mysql 驅動程序： http : //dev.mysql.com/downloads/connector/j/

(2)將mysql驅動復制到：WILDFLY_HOME/modules/system/layers/base/com/mysql/main

(3) 從 JBoss（或 Wildfly）控制台，運行命令：

/subsystem=datasources/jdbc-driver=mysql:add(driver-name=mysql, driver-module-name=com.mysql, driver-class-name=com.mysql.jdbc.Driver)

(4) 然后，再次從 JBoss（或 Wildfly）控制台，運行命令：

/subsystem=datasources/data-source=YourDS:add(driver-name=mysql, user-name=USERNAME, password=PASSWORD, connection-url=jdbc:mysql://localhost:3306/YOURDATABASE, min-pool-size=5, max-pool-size=15, jndi-name=java:jboss/datasources/YourDS, enabled=true, validate-on-match=true, valid-connection-checker-class-name=org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker, exception-sorter-class-name=org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter)

瞧。 現在你有一個 JNDI 路徑的數據源：java:jboss/datasources/YourDS

Answer 5

檢查默認綁定配置是否引用了正確的數據源： https : //docs.jboss.org/author/display/WFLY8/Default+EE+Bindings+Configuration

Answer 6

我有

service jboss.naming.context.java.jboss.datasourservice jboss.naming.context.java.jboss.datasources.ExampleDS（缺失）依賴：...

在 Wildfly-8.1.0.Final 上。

恕我直言

在standalone/configuration/standalone-full.xml它有

<default-bindings ... datasource="java:jboss/datasources/ExampleDS" ...

和

<datasource jndi-name="java:/datasources/ExampleDS"...

jndi-name 不匹配！

我用 jndi-name="java:jboss/datasources/ExampleDS" 創建了 ExampleDS2。 這解決了我的問題。
