Java 我想使用springboot和hibernate创建一个表，虽然没有错误，但表可以'；不能创造，为什么？

下面是

应用程序属性

：

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

下面是我认为正确的

但当我运行它时，控制台会显示：

另一个什么都不是。但是表不能创建。

将

spring.jpa.hibernate.ddl auto=update

更改为

spring.jpa.hibernate.ddl auto=create

…注意spring.jpa.hibernate.ddl-auto不应该在prod中使用。

我遇到了同样的问题，我通过将h2控制台的实际路径复制到

spring.datasource.url=”“

---

在

application.properties

中，从

pom.xml

中删除

hibernate核心

依赖项，通过

spring boot starter数据jpa对其进行过渡式管理

好的，我会尝试。
