安装 (startup.bat) 脚本无法启动我的应用程序，出现错误

Question

我正在尝试创建将启动我的 Java 应用程序的 .bat 脚本。应用程序使用了很多依赖项，所以我必须创建一个 fat jar:

我通过将此依赖项添加到我的 pom.xml:

来做到这一点

pom.xml

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>3.1.1</version>
    
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <mainClass>my.path.MicroserviceApp</mainClass>
                        </manifest>
                    </archive>
                    
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                </configuration>
    
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>

            </plugin>

之后，我执行了 maven clean install，在我的目标文件夹中创建了两个 jar 文件。一个 'normal' 罐子和一个胖子罐子。我使用了那个 fat jar 的路径，我试图通过我的脚本运行它但是我得到了错误。

蝙蝠脚本：

echo off

set "JAVA_HOME=C:/Program Files/Java/jdk1.8.0_291"
set "PATH=C:/Program Files/Java/jdk1.8.0_291/bin;%PATH%"
set "MICRO_HTTP=C:/Users/just.quest/workspace/application_parent/MicroserviceApp"

set "CLASSPATH=%MICRO_HTTP%/target/MicroserviceApp-20.14.1-1-jar-with-dependencies.jar"

java -jar %CLASSPATH%

pause

我得到的错误：

如您所见，java.lang.IllegalArgumentException 似乎存在一些问题：META-INF/spring.factories 中未找到自动配置类。

我已经尝试 google 这个，但我找不到任何有用的东西，而且我已经在这上面花了太多时间，所以我别无选择。我希望有人知道如何从命令提示符启动应用程序。

当我从 Eclipse 启动应用程序时，一切正常。仅当我使用 .bat 脚本时才会出现此错误。

谢谢M。 Deinum，解决了我的问题：

我不得不将 maven-assembly-plugin 替换为：

      <build>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                    <configuration>
                         <classifier>exec</classifier>
                    </configuration>
                 </execution>
            </executions>
