如何让我的弹簧启动应用程序找到我的mysql jdbc jar？

Question

我得到这个错误： “：java.lang.IllegalStateException：致无法加载驱动程序类：com.mysql.jdbc.Driver”

这里是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> 

这里是我的应用程序性能：

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.MySQLDial‌​ect 

以下是完整的堆栈跟踪：

Answer 1

没有必要在你的application.properties提到的“Drivers”两次检查，它产生于哪个驱动程序应该注入冲突。你已经在pom.xml中再次提到它。在application.properties中提到一次DriverClassName就足够了。

请与下面的pom.xml依赖

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

     <dependency>
