java - 在具有多个数据源的 JBOSS 上部署应用程序时出现问题

Question

您好，我正在尝试在 JBOSS EAP 7.1 上部署两个 war 文件。这两个都是 spring boot 应用程序，我已为其配置了 JNDI 查找。我的 Standalone.xml 文件看起来像这样..

 <datasources>
            <datasource jndi-name="java:/JNDI1" pool-name="JNDIPool1" enabled="true" use-java-context="true">
                <connection-url>jdbc:mysql://localhost:3306/test_schema</connection-url>
                <driver>mysql</driver>
                <security>
                    <user-name>test1</user-name>
                    <password>test1</password>
                </security>
            </datasource>
            <datasource jndi-name="java:/JNDI2" pool-name="JNDIPool2" enabled="true" use-java-context="true">
                <connection-url>jdbc:mysql://localhost:3306/test_schema_2</connection-url>
                <driver>mysql</driver>
                <security>
                    <user-name>test2</user-name>
                    <password>test2</password>
                </security>
            </datasource>
            <drivers>
                <driver name="mysql" module="com.mysql"/>
            </drivers>
        </datasources>

每个 war 文件都使用不同的 JNDI 查找。当我同时部署它们时，其中一个 War 文件会部署到另一个 War 文件，而另一个会失败并出现以下错误。任何帮助，将不胜感激。谢谢。

请在 web.xml 中为每个应用程序分配不同的上下文根。我猜你正在使用默认 <context-root>/</context-root> ，导致第二次 war 的 DuplicateServiceException 。将其更改为 <context-root>/app1</context-root> & <context-root>/app2</context-root>
