由于以下原因，我在运行可运行的 jar 时遇到了一些麻烦

HHH000318: Could not find any META-INF/persistence.xml file in the classpath

目录结构： 在此处输入图像描述

JAR META-INF/清单内容：

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: Antoniossss
Build-Jdk: 1.8.0_40
Main-Class: app.remote.Bootstrap
Class-Path: .

从根目录运行命令：

java -jar controller-1.0-jar-with-dependencies.jar

这导致

13:19:50.634 [main] DEBUG o.h.b.r.c.i.ClassLoaderServiceImpl - Incoming config yielded no classloaders; adding standard SE ones

未找到 META-INF/perstistence.xml

但它在 META-INF 目录中。而且config.cfg被正确读取，所以当前目录确实在类路径中。

对我来说奇怪的是以下命令运行得很好：

java -cp controller-1.0-jar-with-dependencies.jar; app.remote.Bootstrap

但是，如果我在 jar 名称后删除分号 (;)，则错误与 jar 午餐尝试期间相同。

java -cp controller-1.0-jar-with-dependencies.jar app.remote.Bootstrap

有什么想法吗？jar 是用 maven 创建的

<plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <mainClass>app.remote.Bootstrap</mainClass>
                        </manifest>
                        <manifestEntries>
                              <Class-Path>.</Class-Path>
                        </manifestEntries>
                    </archive>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id> <!-- this is used for inheritance merges -->
                        <phase>package</phase> <!-- bind to the packaging phase -->
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>

尝试在 pom.xml 中添加

<resources>
        <resource>
            <directory>path_to_your_resource_folder</directory>
            <filtering>true</filtering>
        </resource>
</resources>

path_to_your_resource_folder 是项目文件夹路径中带有 persistence.xml 的目录的路径。我建议您创建一些目录，例如 src/main/resources 并在此处粘贴 persistence.xml。然后 path_to_your_resource_folder=src/main/resources
