这是我的application.properties文件:

This is my application.properties file:

spring.mvc.view.prefix:/WEB-INF/jsp/
spring.mvc.view.suffix:.jsp

spring.datasource.url=jdbc:mysql://localhost:3306/taskdb?useSSL=false
spring.datasource.data-username:springuser
spring.datasource.data-password:1Qazxsw@        
spring.datasource.driver-class-name:com.mysql.jdbc.Driver

spring.jpa.properties.hibernate.dialect:org.hibernate.dialect.MySQL5Dialect
logging.level.org.hibernate.SQL:debug

让我知道是否要我在pom.xml中包含我所依赖的列表. 您能为我提供的任何指导都将不胜感激. 预先感谢！

Let me know if you want me to include the list of dependencias that I have in my pom.xml. Any guidance you can point me is greatly appreciated. thanks in advance!

推荐答案

只需在属性文件的属性文件中执行此操作: 改变这个

Just do this in the properties file in the properties file: Change this

spring.datasource.url=jdbc:mysql://localhost:3306/taskdb?useSSL=false
spring.datasource.username=springuser
spring.datasource.password=1Qazxsw@

对此:

spring.datasource.url=jdbc:mysql://localhost:3306/taskdb?user=springuser&password=1Qazxsw@

这将适用于spring Spring Boot ::(v2.1.2.RELEASE)

This will work for spring Spring Boot :: (v2.1.2.RELEASE)
