1.在pom文件中添加如下

    <plugins>
        <!--解决SpringBoot打包成jar后运行提示没有主清单属性-->
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
				<fork>true</fork>
			</configuration>
        </plugin>
    </plugins>

  <build>
      <plugins>
          <plugin>
              <groupId>org.springframework.boot</groupId>

              <executions>
                  <execution>
                      <goals>
                          <goal>repackage</goal>
                      </goals>
