使用JPA的Sprint Boot - 创建bean时出错，名称为'entityManagerFactory' - 需要使用driverClassName的jdbcUrl。

我正在创建一个Spring Boot应用程序，将JPA实体保存到托管在Heroku上的postgres数据库中（首先在本地主机上加快进展）。我已经花了几天的时间来尝试解决这个问题，现在我不得不寻求帮助。

我的application.propreties文件如下所示：

spring.datasource.url=postgres://localhost:5432/mydb

spring.datasource.username=myuser

spring.datasource.password=mypass

spring.datasource.driverClassName=org.postgresql.Driver

spring.datasource.maxActive=10

spring.datasource.maxIdle=5

spring.datasource.minIdle=2

spring.datasource.initialSize=5

spring.datasource.removeAbandoned=true

我得到了以下错误：

问题出现的原因是在使用Spring Boot 2.0.x版本时，默认的数据源连接池是HikariCP。而当使用spring-boot-starter-data-jpa依赖时，HikariCP并不知道spring.datasource.url这个属性，而是使用spring.datasource.jdbc-url来指定数据库的URL。因此，解决这个问题的方法是将spring.datasource.url改为spring.datasource.jdbc-url，如下所示：

spring.datasource.jdbc-url=postgres://localhost:5432/mydb

在这种情况下，不需要再告诉Spring关于spring.datasource.type的信息，因为它已经默认使用Hikari作为数据源连接池。如果想要切换回Tomcat JDBC而不使用Hikari，可以参考这个Stack Overflow回答。

根据堆栈跟踪，问题出在Hikari配置上。

你可能需要设置以下属性：datasource.type

spring.datasource.type=com.zaxxer.hikari.HikariDataSource
# hikari specific properties
spring.datasource.hikari.maximum-pool-size=50
spring.datasource.hikari.idle-timeout=1000
spring.datasource.hikari.pool-name=blah

关于Hikari的更多信息请查看属性

我按照你说的做了，还注释掉了driverClassName，改用dataSourceClassName=org.postgresql.ds.PGSimpleDataSource。看起来问题解决了！现在要解决新手自动装配的问题了！非常感谢-你真棒！
