Caused by: java.lang.RuntimeException: Unknown dialect.原因
This error appears when the database is using a non-standard dialect and Confluence Questions or Team Calendars are looking for a specific one.
The dialects used by Confluence as of 5.6.1 are:
"net.sf.hibernate.dialect.PostgreSQLDialect",
"com.atlassian.hibernate.dialect.MySQLDialect",
"net.sf.hibernate.dialect.SQLServerIntlDialect",
"net.sf.hibernate.dialect.OracleIntlDialect"ソリューション
- Confluence をシャットダウンします。
- Navigate to the home directory
- (The <confluence_home> directory is the path defined in the following file: <confluence_install>/confluence/WEB-INF/classes/confluence-init.properties)
- Modify the confluence.cfg.xml file
There is a line that begins
<property name="hibernate.dialect">We will need to update the property associated with it.
The value used depends on the database in use. Please refer to the listed dialects in the 'Cause' section. In the following example, we'll use MySQL.
If you're using an older version of Confluence, the dialect may be different. If in doubt, please contact Atlassian Support.
Please confirm that the property reads
net.sf.hibernate.dialect.MySQLDialectIf so, please change the property to
com.atlassian.hibernate.dialect.MySQLDialectThe entire line should now look like this:
<property name="hibernate.dialect">com.atlassian.hibernate.dialect.MySQLDialect</property>
Save the file
Start Confluence and check if questions is working correctly
