此處不允許使用 Grails 和 Mysql 連接映射值

Question

這是我在 Mysql Db 連接到 Grails 項目時遇到問題，我已經創建了這個數據庫，名稱為來自終端的汽車，一切正常。 但是當我嘗試運行我的應用程序時，我收到此錯誤。

| 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)

這是我的 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

這是我已經添加到依賴項中的 build.gradle 文件

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

我認為您在第 17 行有一個額外的空間。在括號內。

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

您可以在此站點上測試您的 yml 文件：http: //yaml-online-parser.appspot.com/

像這樣嘗試：

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
