带有数据源的 Wildfly 配置

Question

这是我第一次尝试在 Wildfly 服务器中设置数据源。 我尝试按照我在 Google 上找到的一些教程进行操作，但仍然无效。

我正在开发一个 Web 服务，但在部署 .war 文件时我不断收到一些错误。

这是部署应用程序时的最新日志：

Answer 1

进入您的 wildfly 控制台（类似于 localhost:9990）并编辑 Configuration->Container->EE->Default Bindings 部分。 将默认数据源设置为某个有效数据源的 JNDI 名称。

我删除了那里的默认值，并将其指向我的主数据源，因为该服务器仅用于运行一个应用程序。

Answer 2

您的 standalone.xml xmlns "urn:jboss:domain:datasources:2.0" 部分中可能缺少 ds 声明 "java:jboss/datasources/ExampleDS"，它会起作用（这是默认配置中的示例）：

            <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>

或者您也可以通过其他响应提到的 UI 添加。

Answer 3

你能发布你的数据源定义吗？

我认为最好测试数据源部署“独立”。 我的意思是与实际应用程序部署分开，只是为了测试您的数据源是否有效。 您可以使用 Web 控制台 (localhost:9990/console) 测试此 fi。

看起来wildfly的预配置示例DS也存在问题。 您是否删除了此 DS？ 在standalone.xml 中还有一个对ExampleDS 的引用，它可能被破坏了。

Answer 4

假设您使用的是 MySQL DB，您可以通过以下方式创建 DS：

(1) 从这里下载 mysql 驱动程序： http : //dev.mysql.com/downloads/connector/j/

(2)将mysql驱动复制到：WILDFLY_HOME/modules/system/layers/base/com/mysql/main

(3) 从 JBoss（或 Wildfly）控制台，运行命令：

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

(4) 然后，再次从 JBoss（或 Wildfly）控制台，运行命令：

/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。 现在你有一个 JNDI 路径的数据源：java:jboss/datasources/YourDS

Answer 5

检查默认绑定配置是否引用了正确的数据源： 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）依赖：...

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" 创建了 ExampleDS2。 这解决了我的问题。
