When using Hibernate-tools to automatically generate Java classes and schemas, the found while looking is not present ... Abnormal

Problem Description:

When using Hibernate-tools, the found while looking is present ... (Specific information omitted).

Problem Analysis:

I found an error corresponding to the Hbm.xml file, where the ID is defined as:

<IDname= "Commentid"column= "comment_id">            <Metaattribute= "Scope-set">Private</Meta>            <!--for MySQL auto-grow -            <Generatorclass= "Native" />
</ID>

found that the original is missing type= "XXXX"; no type defined

Problem solving:

<IDname= "Commentid"type= "Long"column= "comment_id">            <Metaattribute= "Scope-set">Private</Meta>            <!--for MySQL auto-grow -            <Generatorclass= "Native" /></ID>
