Spring 启动应用程序 jar 无法运行

Question

I have a spring boot app and wanted to try to create executable to deploy on the server. I haven't done this before so I followed instructions and firstly run it through maven - which was running correctly, then I wanted to execute a jar after packaging which resulted in the described error:

java -jar target/app.jar

I searched for familiar topics and haven't found the answer, I believe this is something obvious because the app is very simple so as the pom.xml. The class which causes error is not(as it is said in stack trace) in the jar file. Am I something missing which downloads dependencies to jar?

Answer 1

Try this

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

From here

Hi I think you should add this plugins.

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

Can you try
