Spring-Boot: сбой при запуске весенней загрузки успокоительной программы

Question

Я новичок в весенней загрузке. Я написал очень простой релаксирующий проект для выполнения действий CRUD над сущностью, и я использую jpa и sql server. Когда я его запускаю, происходит сбой, и ошибка связана с базой данных и драйвером.

Я прочитал почти все вопросы, связанные с этой ошибкой, и ни один из них не был ответом.

Вот вся информация:

application.properties:
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect
spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=restful;integratedSecurity=true
spring.datasource.initialize=true
spring.jpa.database=SQL_SERVER
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto = create-drop

spring.datasource.tomcat.max-wait=20000
spring.datasource.tomcat.max-active=50
spring.datasource.tomcat.max-idle=20

Исключение:

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Failed to determine a suitable driver class

в конце написано:

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

Примечание: одна вещь, которую я не могу понять, это то, что я зарегистрировал зависимость для драйвера сервера sql в pom.xml , но библиотека не существует в External Library .

Привет

Answer 1

Попробуйте это:

1) Щелкните правой кнопкой мыши Project.

2) Maven -> Обновить проект

3) Обновить проект снова.

Или попробуйте с другой зависимостью
