Question

我的应用程序出现异常行为。

从IDE（Intellij）中启动主类工作正常。

使用

mvn spring-boot：run

该应用程序也可以正常运行。

但是当尝试从jar启动应用程序时，我得到了

java.lang.ClassNotFoundException: org.springframework.boot.SpringApplication

由于我的最终目标是使其与Docker一起使用，所以我希望它与以下设备一起运行：

java -jar ./target/mail-business-1.0-SNAPSHOT.jar

检查了几篇文章之后，我检查了相关性，删除了目标文件夹，以便可以重新创建它，但问题仍然存在。

会有人有主意吗？我正在考虑某些依赖项兼容性，但到目前为止我进行的测试均未成功

下面是我的pom.xl

我在本地尝试过，并通过添加以下内容使其起作用：

           <plugin>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.1.2.RELEASE</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

，然后在“清理”之后运行“安装”或“软件包”。

https://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html

从本质上讲，该插件似乎没有重新创建您的原始jar。如果您查看/ target /，现在应该看到一个.jar.original。

运行jar时出现ClassNotFoundException，但运行类时没有问题
