Spring 啟動應用程序 jar 無法運行

Question

我有一個 spring 啟動應用程序，並想嘗試創建可執行文件以部署在服務器上。 我之前沒有這樣做過，所以我按照說明首先通過 maven 運行它 - 它運行正常，然后我想在打包后執行 jar 導致描述的錯誤：

java -jar target/app.jar

我搜索了熟悉的主題並沒有找到答案，我相信這是顯而易見的，因為該應用程序非常簡單，例如 pom.xml。 導致錯誤的 class 不在 jar 文件中（如堆棧跟蹤中所述）。 我是否缺少將依賴項下載到 jar 的東西？

import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class FileSynchronizerClientApplication {

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

}

Answer 1

嘗試這個

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

從這里

Answer 2

嗨，我認為您應該添加此插件。

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

你能試一下嗎
