java - 服务器部署 springboot 项目报错,我应该怎么解决？

Question

把Springtboot在宝塔上部署的时候提示问题

Exception in thread "main" java.lang.ClassNotFoundException: classes.com.example.demo.DemoApplication    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)    at 

打包jar出来在本地上java也提示了：

Exception in thread "main" java.lang.reflect.InvocationTargetException        at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:119)        at java.base/java.lang.reflect.Method.invoke(Method.java:578)        at org.springframework.boot.loader.MainMethodRunner.run(MainMethodRunner.java:49)        at org.springframework.boot.loader.Launcher.launch(Launcher.java:108)        at org.springframework.boot.loader.Launcher.launch(Launcher.java:58)        at org.springframework.boot.loader.JarLauncher.main(JarLauncher.java:88)Caused by: java.lang.NoClassDefFoundError: org/springframework/boot/SpringApplication        at com.example.demo.DemoApplication.main(DemoApplication.java:10)        at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:104)        ... 5 moreCaused by: java.lang.ClassNotFoundException: org.springframework.boot.SpringApplication        at java.base/java.net.URLClassLoader.findClass(URLClassLoader.java:445)        at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:588)        at org.springframework.boot.loader.LaunchedURLClassLoader.loadClass(LaunchedURLClassLoader.java:151)        at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521)        ... 7 more

以下是我的pom.xml：

我这边打包出来是存在于的XTool解压后是存在XTool\BOOT-INF\classes\com\example\demo，也试过换成classes.com.example.demo.DemoApplication但是都没有效果，我应该怎么解决？

Answer 1

去掉

                    <includes>                        <include>                            <groupId>nothing</groupId>                            <artifactId>nothing</artifactId>                        </include>                    </includes>

Answer 2

先本地部署看是否报错。
本地 Java -jar，把 spring-boot-maven-plugin 中的 configuration、executions 去掉再 package 试试。
