Springboot引入jpa时启动失败，撤销之后又能正常启动

Question

使用工具是STS，springboot+maven；在pom.xml中引入

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-data-jpa</artifactId>

</dependency>

后启动报错！

错误信息如下：

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

2017-07-03 11:41:01.291 ERROR 3312 --- [           main] o.s.boot.SpringApplication               : Application startup failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javassist/bytecode/ClassFile

怎么解决？求大牛帮忙科普下。。。

配置里面不要dhcp比如下面：spring: profiles:   active: dev datasource:   driver-class-name: com.mysql.jdbc.Driver   url: jdbc:mysql://127.0.0.1:3306/dbgirl   username: root   password: 123456 jpa:   hibernate:     ddl-auto: create   show-sql: true
