Question

我收到此错误：“引起：java.lang.IllegalStateException：无法加载驱动程序类：com.mysql.jdbc.Driver ”

这是POM部分：

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>

这是我的应用程序属性：

spring.datasource.url = jdbc:mysql://localhost
spring.datasource.driverClassName = com.mysql.jdbc.Driver 
spring.datasource.name=demodb 
spring.datasource.username=root@localhost
spring.datasource.password=1234
spring.datasource.driver-class-name= com.mysql.jdbc.Driver 
spring.jpa.database=mysql 
spring.jpa.database-platform=org.hibernate.dialect.MySQLDial‌ect

这是完整的堆栈跟踪：

请查看以下pom.xml依赖项

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>

        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>

Answer 2

没有必要提及＆＃34;司机＆＃34;在你的application.properties中，它出现了两次应该注入的驱动程序的冲突。你在pom.xml中再次提到它。在application.properties中提到一次DriverClassName就足够了。
