我试图将多模块项目转换为wildfly-swarm。但是,我不知道如何正确设置它。
当我从核心目录运行mvn wildfly-swarm:run
时,它会启动服务器,并且错误显示它找不到我的持久性单元。 persistence.xml
位于DBlayer
模块中,因此有意义。
我试图从根目录运行它,但它说没有定义插件群。所以我尝试在root
pom.xml而不是core
模块pom.xml中定义插件,但无法创建-swarm.jar
。
那我该怎么设置呢?
这是我的root pom.xml

<artifactId>DBLayer</artifactId>
</project>
我没有指定任何主要方法。我在DBLayer中只有一个persistence.xml:
DBLayer / SRC /主/资源/ META-INF
所以我有点假设swarm会自动处理以定义驱动程序和数据源。我的意思是在wildfly中你需要在standalone.xml中定义驱动程序和数据源。在这里我什么也没做,所以也许这就是问题。然而,在他们的例子中,他们也没有这样做。 https://github.com/wildfly-swarm/wildfly-swarm-examples/blob/master/jpa/jpa-war/src/main/resources/META-INF/persistence.xml
这是我的持久单元:
<persistence version="2.1"
xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

</persistence-unit>
</persistence>

在多模块Maven项目中,请记住直接从根POM启动Maven命令。
首先,将wildfly-swarm-plugin
声明保留在WAR模块中,将它放在其他地方是不合适的,因为它适用于WAR项目。然后,您需要安装模块DBLayer
,以便模块core
(这是您的WAR)可以看到它(因此,可以看到它的persistence.xml
)。最后,您需要确保仅使用-pl
命令行开关在WAR模块中调用目标wildfly-swarm:run
。
因此,从根POM调用命令:
mvn clean install && mvn -pl core wildfly-swarm:run
这将正确构建您的多模块项目并使用Wildfly Swarm插件运行WAR。您可以找到此类设置on this GitHub repo的实际示例。
