mybatis returns the inserted primary key and reports an error

Using Mybatis today, after configuring the XML file, an error is reported at startup, and the error message is as follows :

       

Caused by: org.apache.ibatis.builder.BuilderException: Error creating document instance. Cause: org.xml.sax.SAXParseException; lineNumber: 9; columnNumber: 22; Property "order" with value "before" must have a list" BEFORE AFTER ".
	at org.apache.ibatis.parsing.XPathParser.createDocument(XPathParser.java:253)
	at org.apache.ibatis.parsing.XPathParser.<init>(XPathParser.java:122)

	at org.apache.ibatis.builder.xml.XMLConfigBuilder.parseConfiguration(XMLConfigBuilder.java:104)
	... 26 more

    The insert configuration in xml is as follows :

   

<selectKey keyProperty="rptqueryId" order="before"
			resultType="long">
			select rpt_seq$seq.nextval from dual
		</selectKey>

   Error reason :

   The order value must be one of BEFORE AFTER, case sensitive .

 

   Correction: Change before to BEFORE .
