Question

这里是我有问题与Mysql Db连接Grails项目，我已经创建这个数据库与名称汽车从终端一切都是okey。但是，当我尝试运行我的应用程序时，我收到此错误。

| 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build.gradle文件，我已经添加到依赖项这个

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

我认为你在第17行有一个额外的空格。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/

试试这样：

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

Grails＆amp;此处不允许使用Mysql连接映射值
