Spring 引导连接到 Java 中的 MySQL 错误
[英]Spring Boot connection to MySQL in Java Error
问题描述
I have already created a database named 'sid' in my sql still it gives an error stating ->
我已经在我的 sql 中创建了一个名为“sid”的数据库，但它仍然给出错误说明 - >
"unknown database sid" “未知数据库 sid”
I have given the code for the following two files below related to the connection in spring boot to MySQL.我已经给出了以下两个文件的代码，这些文件与 spring 引导到 MySQL 中的连接有关。 I have also copied the long thread of exception just below it.我还复制了它下面的长长的异常线程。
application.properties file -> application.properties 文件->
#Changing the server port
server.port = 9090
#database configuration : mysql
spring.datasource.url = jdbc:mysql://localhost:3306/sid
spring.datasource.username = root
spring.datasource.password = Ageofempires11!
spring.datasource.driver-class-name = com.mysql.cj.jdbc.Driver
#hibernate configuration
spring.jpa.hibernate.ddl-auto = update
spring.jpa.show-sql = true
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL8Dialect
pom.xml file -> pom.xml 文件->

Looking at the error it seems database "sid" doesn't exists.查看错误似乎数据库“sid”不存在。 Please create database using below command in mysql terminal or client请在 mysql 终端或客户端中使用以下命令创建数据库
CREATE database sid
Also you use below property to let spring create DB if it doesn't exists.如果数据库不存在，您还可以使用以下属性让 spring 创建数据库。 add below properties in properties file在属性文件中添加以下属性
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.hibernate.ddl-auto=create
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=Ageofempires11!
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
spring.datasource.url=jdbc:mysql://localhost:3306/sid?createDatabaseIfNotExist=true&useSSL=true
