mysql - 此处不允许使用 Grails 和 Mysql 连接映射值

Question

这里是我在 Mysql 数据库连接到 Grails 项目时遇到问题，我已经从终端创建了名称为 cars 的数据库，一切正常。但是当我尝试运行我的应用程序时，出现了这个错误。

| Error Error occurred running Grails CLI: mapping values are not allowed here
 in 'reader', line 107, column 17:
                 url: "jdbc:mysql://localhost:3306/cars"
                    ^
 (Use --stacktrace to see the full trace)

这是我的 application.yml 文件

dataSource:
    pooled: true
    jmxExport: true
    driverClassName: "com.mysql.jdbc.Driver"
    username: "root"
    password: "1234"


environments:
    development:
        dataSource:
            dbCreate: update
            url: "jdbc:mysql://localhost:3306/cars"
    test:
        dataSource:
            dbCreate: update
             url: "jdbc:mysql://localhost:3306/cars"
    production:
        dataSource:
            dbCreate: none
            url: "jdbc:mysql://localhost:3306/cars"
            properties:
                jmxEnabled: true
                initialSize: 5
                maxActive: 50
                minIdle: 5
                maxIdle: 25
                maxWait: 10000
                maxAge: 600000
                timeBetweenEvictionRunsMillis: 5000
                minEvictableIdleTimeMillis: 60000
                validationQuery: SELECT 1
                validationQueryTimeout: 3
                validationInterval: 15000
                testOnBorrow: true
                testWhileIdle: true
                testOnReturn: false
                jdbcInterceptors: ConnectionState
                defaultTransactionIsolation: 2 # TRANSACTION_READ_COMMITTED

这是我已经添加到依赖项中的 build.gradle 文件

runtime 'mysql:mysql-connector-java:5.1.29'

我认为你在第 17 行有一个额外的空间。在括号内。

        dbCreate: update
        [ ]url: "jdbc:mysql://localhost:3306/cars"

您可以在此站点测试您的 yml 文件:http://yaml-online-parser.appspot.com/

像这样尝试:

dataSource:    pooled: true    jmxExport: true    driverClassName: "com.mysql.jdbc.Driver"    username: "root"    password: "1234"environments:    development:        dataSource:            dbCreate: update            url: 'jdbc:mysql://localhost:3306/cars'    test:        dataSource:            dbCreate: update            url: 'jdbc:mysql://localhost:3306/cars'    production:        dataSource:            dbCreate: none            url: "jdbc:mysql://localhost:3306/cars"            properties:                jmxEnabled: true                initialSize: 5                maxActive: 50                minIdle: 5                maxIdle: 25                maxWait: 10000                maxAge: 600000                timeBetweenEvictionRunsMillis: 5000                minEvictableIdleTimeMillis: 60000                validationQuery: SELECT 1                validationQueryTimeout: 3                validationInterval: 15000                testOnBorrow: true                testWhileIdle: true                testOnReturn: false                jdbcInterceptors: ConnectionState                defaultTransactionIsolation: 2 # TRANSACTION_READ_COMMITTED
