我是目錄

昨天本來想要一口氣講完，但是發現篇幅好像有點長，所以決定切兩部份。

設定專案環境參數

grails-app/conf/application.yml

grails-app/conf/application.yml 主要是專案的參數文件配置。

在 grails 框架中有三個預設環境，方便在不同環境中切換:

• development: 開發環境
• test: 測試環境
• production: 生產環境

在 development 因為有配置 spring-boot-devtools ，所以在更動程式原始碼時，會啟用熱部屬。

另外如果有第四種以上的環境需要特別部屬，可以自行命名，範例如下:

• grails-app/conf/application.yml

...
environments:
    test:
        dataSource:
            dbCreate: none
            url: jdbc:postgresql://127.0.0.1:5432/ironman_dict_db
    example:
        dataSource:
            dbCreate: none
            url: jdbc:postgresql://127.0.0.1:5432/ironman_dict_db
...

在執行，時需要加參數指定環境: -Dgrails.env

-Dgrails.env=example

不同環境的log配置

grails log 預設是 grails-app/conf/logback.xml，有需求可以另外新增。以下是針對不同環境處理的文件:

• 預設: grails-app/conf/logback.xml
• 測試環境: grails-app/conf/logback-test.xml
• 開發環境: grails-app/conf/logback-development.xml

相對應的文件描述如下

• grails-app/conf/application.yml

...
environments:
    development:
        logging:
            config: grails-app/conf/logback-development.xml
    test:
        logging:
            config: "${catalina.base}/webapps/ironman-dict/WEB-INF/classes/logback-test.xml"
...

• grails-app/conf/logback.xml
