如何部署Grails戰爭到tomcat

Question

我遇到了WAR文件的問題，我想部署到Tomcat服務器8. tomcat服務器安裝了默認值（僅更改了用戶和密碼）。 當我部署WAR文件，我碰到catalina.out的日誌輸出：

我的猜測是，有與MySQL連接的問題，但我真的不知道我應該在哪裏指定連接字符串或類似的東西......數據庫在服務器上創建，而Grails中的DataSource指向該數據庫。

我加入這個上面的配置到Tomcat，但仍無法連接。我開始對這個問題有點絕望。

Answer 1

經過一週的努力解決這個問題後，我在一位同事和Tomcat doc的幫助下找到了解決方案。
的配置在context.xml文件提出，內容如下：

<Resource name="jdbc/turismoBackend" auth="Container" type="javax.sql.DataSource" 
       maxTotal="100" maxIdle="30" maxWaitMillis="10000" 
       username="youruser" password="yourpassword" driverClassName="com.mysql.jdbc.Driver" 
       url="jdbc:mysql://localhost:3306/yourdb"/> 

這是值得的通知，從根本不同的用戶，以創建爲Tomcat來訪問MySQL，與所有特權和也授予選項。像這樣：

CREATE USER '[yourUsername]'@'localhost' IDENTIFIED BY '[yourPassword]'; 
GRANT ALL PRIVILEGES TO [yourUsername]@[yourServer] IDENTIFIED BY [yourPassword] WITH GRANT OPTION; 

就是這樣！一切都在運行。

Answer 2

從堆棧跟蹤中提取;

Missing type or column for column[descripciono_descripciones] on domain[Ejercicios] 

如果列名不與用於駝峯強調格式約定匹配，那麼人們通常會得到從冬眠MappingException。如果是這樣的話，則映射必須由使用column:

例如，airportCode column: 'AIRPORT_CD'

解決可能會解決部署問題，以及在mappings部分manully完成（考慮有沒有其他的道路塊） 。
