问题：

servlet-api的jar包和springboot的启动jar包产生冲突

servlet-api.jar<dependency>    <groupId>javax.servlet</groupId>    <artifactId>javax.servlet-api</artifactId>    <version>3.1.0</version>    <scope>provided</scope></dependency>

springBoot启动jar包

<dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-data-jpa</artifactId>    </dependency>

解决办法：

把servlet-api的依赖删除，启动正常
