java - 在具有多个数据源的 JBOSS 上部署应用程序时出现问题

问题描述

您好我正在尝试在 JBOSS EAP 7.1 上部署两个战争文件。这两个都是我为其配置了 JNDI 查找的 spring boot 应用程序。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>

每个战争文件都使用不同的 JNDI 查找。当我同时部署它们时，其中一个战争被部署，而另一个战争失败并出现以下错误。任何帮助，将不胜感激。谢谢。

解决方案

请为 web.xml 中的每个应用程序分配不同的上下文根。我猜你正在使用 default <context-root>/</context-root>，导致第二次战争 DuplicateServiceException 。将其更改为<context-root>/app1</context-root>&<context-root>/app2</context-root>
