Question

我正在使用grails版本3.1.4，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，但是我收到以下错误：

ERROR org.springframework.boot.SpringApplication - Application startup failed

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。欢呼声。

你在application.yml中输入了错误的配置：

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

无法将mysql连接到Grails 3应用程序
