请帮我解决这个问题。

Answer 1

在 pom 的构建部分中，您需要包含 spring-boot-plugin 并定义主类。

<build>
  <plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>             
        <configuration>    
            <mainClass>com.yourpackage.YourMainApplicationClassName</mainClass>
        </configuration>
    </plugin>
  </plugins>
</build>

所以，如果我的主应用程序类是

MainClass

包中的

com.acme

，我会将 mainClass 属性设置为

com.acme.MainClass
