添加原因是没有找到入口类，在pom添加如下配置即可`

  <build>
    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <!--使用热部署出现中文乱码解决方案-->
        <configuration>
          <fork>true</fork>
          <!--增加jvm参数-->
          <jvmArguments>-Dfile.encoding=UTF-8</jvmArguments>
          <!--指定入口类-->
          <mainClass>com.ix.SpringbootDemoApplication</mainClass>
        </configuration>
      </plugin>
    </plugins>
  </build>
