Java Spring启动应用程序jar无法运行

我有一个spring boot应用程序，希望尝试创建可执行文件以部署到服务器上。 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，这导致了所描述的错误：

java -jar target/app.jar

我的项目结构：

我的主要课程是：

package com.licencjat.filesynchronizer.client;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class FileSynchronizerClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(FileSynchronizerClientApplication.class, args);
    }

}

嗨，我想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>

org.apache.maven.plugins
maven surefire插件
2.22.0

你能试试这个吗

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

org.springframework.boot
Hi，显示您的
应用程序.properties
文件和项目结构Hi@EugeneMakarenko，我按照你的建议编辑了这篇文章。添加
com.licencjat.filesynchronizer.client.FileSynchronizerClientApplication
too按照你的建议添加。尝试
spring.devtools.livereload.enabled=true
并检查jar文件conatins spring devtools，我刚刚构建了一个包含devtools的springboot项目，在用mvn clean package spring boot:repackage打包后，我在jar文件中看不到这个依赖项。ı理解抱歉ı检查了但ı找不到谢谢，我不知道默认情况下它们被排除在外。
