我是一个spring新手，我正在遵循一个教程来构建一个需要连接到mysql数据库的应用程序。我可以用相同的凭据使用mysql workbench连接到db，但在运行应用程序时，我得到以下错误堆栈：

这是我的application.properties文件：

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

如果您想让我在pom.xml中包含依赖项列表，请告诉我。非常感谢您给我指点迷津。提前谢谢！

解决方案更新：
它与我的应用程序的属性有关，我更新了它如下，现在它可以工作了：

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

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

因此，属性文件中的“：”更改为“=”

只需在属性文件中的属性文件中执行以下操作：更改此

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 Boot：：（v2.1.2.release）
