spring boot应用程序jar无法运行


我有一个spring boot的应用程序，想尝试创建可执行的部署在服务器上。 我以前没有这样做过，所以我按照说明，首先通过maven运行它--它运行正确，然后我想在打包后执行一个jar，结果出现了所描述的错误:

java -jar target/app.jar

我搜索了一些熟悉的主题，但没有找到答案，我相信这是显而易见的，因为这个应用程序非常简单，就像pom.xml一样。 导致错误的类不在jar文件中（正如堆栈跟踪中所说的那样）。 我是否缺少了一些将依赖项下载到JAR的东西？

试试这个

<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <configuration>
            <excludeDevtools>false</excludeDevtools>
        </configuration>
    </plugin>
</plugins>

从这里开始

嗨，我认为你应该添加这个插件。

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.22.0</version>
        </plugin>

你能试一下吗
