我想用springboot和hibernate創建表，雖然沒有錯誤，但是表不能創建，爲什麼？

Question

這裏是application.properties：

server.port=8080 
spring.thymeleaf.prefix=classpath:/templates/ 
spring.thymeleaf.suffix=.html 
spring.thymeleaf.mode=LEGACYHTML5 
spring.thymeleaf.encoding=UTF-8 
spring.thymeleaf.content-type=text/html 
spring.thymeleaf.cache=false 

spring.datasource.url=jdbc:mysql://127.0.0.1/springboot?characterEncoding=UTF-8&autoReconnect=true&useSSL=false 
spring.datasource.username=root 
spring.datasource.password=root 
spring.datasource.driverClassName=com.mysql.jdbc.Driver 

spring.datasource.max-active=5 
spring.datasource.max-idle=2 
spring.datasource.min-idle=1 
spring.datasource.initial-size=1 
spring.datasource.initialize=false 
spring.datasource.test-on-borrow=false 
spring.datasource.test-on-return=false 
spring.datasource.test-while-idle=true 
#spring.datasource.max-wait-millis=30000 
spring.datasource.validation-query=SELECT 1 
spring.datasource.time-between-eviction-runs-millis=20000 
spring.datasource.min-evictable-idle-time-millis=28700 

# Specify the DBMS 
spring.jpa.database = MYSQL 
# Hibernate ddl auto (create, create-drop, update) 
spring.jpa.hibernate.ddl-auto=update 
spring.jpa.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect 

這裏是pom.xml我認爲這是正確的。

但是當我運行它，控制檯顯示我：

2017年3月3日13：16：57.999 INFO 29616 --- [主] org.hibernate.Version：HHH000412： Hibernate Core {4.3.7.Final}
2017-03-03 13：16：58.001信息29616 --- [main] org.hibernate.cfg.Environment：HHH000206：hibernate.properties找不到
2017-03- 03 13：16：58.003 INFO 29616 --- [main] org.hibernate.cfg.Environment：HHH000021：字節碼提供程序名稱：javassist

和其他什麼都不是。但表不能創建。

Answer 1

變化spring.jpa.hibernate.ddl-auto=update到spring.jpa.hibernate.ddl-auto=create ...筆記spring.jpa.hibernate.ddl，汽車不應該督促使用
