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，但它仍然无法正常工作。

我正在处理Web服务，但在部署.war文件时遇到了一些错误。

以下是部署应用时的最新日志：

告诉我你是否需要更多文件。

Answer 1

进入你的wildfly控制台（类似localhost：9990）并编辑Configuration-＆gt; Container-＆gt; EE-＆gt; Default Bindings部分。将缺省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，因为服务器只存在运行一个应用程序。

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”，只是它会起作用（这是默认示例）配置）：

            <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中提到的UI添加。

Answer 3

你可以发布你的数据源定义吗？

我认为最好是测试数据源部署＆＃39; standalone＆＃39;。我的意思是与实际的应用程序部署分开，只是为了测试您的数据源是否有效。你可以测试这个f.i.使用Web控制台（localhost：9990 / console）。

看起来预配置的wildfly示例DS也存在问题。你删除了这个DS吗？在standalone.xml中，还有一个关于ExampleDS的引用可能会被破坏。

Answer 4

假设您使用的是MySQL数据库，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驱动程序复制到： WILDFLY_HOME /模块/系统/层/基层/ COM / MySQL的/主

（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。现在您有一个JNDI路径为的数据源：的java：JBoss的/数据源/ YourDS

Answer 5

检查default-bindings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（missing）dependents：...

on wildfly-8.1.0.Final。

IMHO

在standalone/configuration/standalone-full.xml中有

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

和

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

jndi-name mismatch！

我使用jndi-name =＆＃34; java：jboss / datasources / ExampleDS＆＃34;创建了ExampleDS2。这解决了我的问题。

使用DataSource的Wildfly配置
