我正在测试Grail 3应用程序以连接在另一台服务器上运行的mogoDB。

独立的Java程序成功连接到数据库。但是Grail 3应用程序无法连接到DB。异常显示其连接到本地主机。

我想了解为什么它不从aplication.yml文件读取连接字符串。

application.yml文件:

environments:
    development:
        grails:
            mongodb:
                connectionString: "mongodb://192.168.1.13:27017/test"

grails> 2017-02-14 22:52:28.116 ERROR --- [nio-8080-exec-9] o.g.web.errors.GrailsExceptionResolver   : MongoTimeoutException occurred when processing request: [GET] /book/index

最佳答案

此配置在开发和生产中都对我有用。

environments:
development:
    grails:
        mongodb:
            host: "localhost"
            port: 27017
            username: ""
            password: ""
            databaseName: "mydb-dev"
production:
    grails:
        mongodb:
            host: "1.1.1.1"
            # host: "localhost"
            port: 27017
            username: ""
            password: ""
            databaseName: "mydb-prod"

compile 'org.grails.plugins:mongodb'
