## spring boot整合hikari遇到的问题 ##

*  问题：  
    1、在添加依赖后，在配置文件中设置如下：

datasource:
        type: com.zaxxer.hikari.HikariDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://localhost:3306/oauth2?useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8
        username: root
        password: root
        hikari:
          minimum-idle: 5
          idle-timeout: 600000
          maximum-pool-size: 10
          auto-commit: true
          pool-name: MyHikariCP
          max-lifetime: 1800000
          connection-timeout: 30000
          connection-test-query: SELECT 1
    
    server:
      port: 8082

2、启动项目后，访问数据库的时候，后台报错

java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName.
    	at com.zaxxer.hikari.HikariConfig.validate(HikariConfig.java:1000) ~[HikariCP-3.4.5.jar:na]
    	at com.zaxxer.hikari.HikariDataSource.getConnection(HikariDataSource.java:109) ~[HikariCP-3.4.5.jar:na]
    	at org.springframework.jdbc.datasource.DataSourceUtils.fetchConnection(DataSourceUtils.java:158) ~[spring-jdbc-5.3.2.jar:5.3.2]
    	at org.springframework.jdbc.datasource.DataSourceUtils.doGetConnection(DataSourceUtils.java:116) ~[spring-jdbc-5.3.2.jar:5.3.2]
    	at org.springframework.jdbc.datasource.DataSourceUtils.getConnection(DataSourceUtils.java:79) ~[spring-jdbc-5.3.2.jar:5.3.2]

*  解决办法：  
    其实只需要将配置文件修改一处（将url修改为jdbc-url）

datasource:
        type: com.zaxxer.hikari.HikariDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        jdbc-url: jdbc:mysql://localhost:3306/oauth2?useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8
