无法将 mysql 连接到 Grails 3 应用程序

Question

我正在使用 grails 3.1.4 版，我正在尝试将我的应用程序连接到 mysql 数据库。 我已经按照How to connect Grails 3.0 to my local Mysql database 的链接将 mysql 数据库连接到我的 Grails 3 应用程序，但我收到以下错误：

这是我的 application.yml

dataSource:
      pooled: true
      jmxExport: true
      driverClassName: com.mysql.jdbc.Driver
      dialect: org.hibernate.dialect.MySQL5InnoDBDialect
      username: root
      password: root123


environments:
    development:
        dataSource:
        dbCreate: update
        url : jdbc:mysql://localhost:3306/collegedb?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true

我还在 build.gradle 文件中添加了runtime 'mysql:mysql-connector-java:5.1.36'。

我在 mysql 上创建了名为 collegedb 的数据库。无法弄清楚是什么问题。任何帮助/建议表示赞赏。干杯。

您在 application.yml 中输入错误的配置：

environments:
    development:
        dataSource:
        dbCreate: update
        url : jdbc:mysql://localhost:3306/collegedb?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true

应该是：

environments:
    development:
        dataSource:
            dbCreate: update
            url : jdbc:mysql://localhost:3306/collegedb?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true
