运行特定的单元测试时,出现异常:
Caused by: org.hibernate.HibernateException: Errors in named queries: UPDATE_NEXT_FIRE_TIME
at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:437)
at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1385)
at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:954)
at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:891)
... 44 more
对于此处定义的命名查询:
@Entity(name="fireTime")
@Table(name="qrtz_triggers")
@NamedQueries({
@NamedQuery(
name="UPDATE_NEXT_FIRE_TIME",
query= "update fireTime t set t.next_fire_time = :epochTime where t.trigger_name = 'CalculationTrigger'")
})
public class JpaFireTimeUpdaterImpl implements FireTimeUpdater {
@Id
@Column(name="next_fire_time", insertable=true, updatable=true)
private long epochTime;
public JpaFireTimeUpdaterImpl() {}
public JpaFireTimeUpdaterImpl(final long epochTime) {
this.epochTime = epochTime;
}
@Override
public long getEpochTime() {
return this.epochTime;
}
public void setEpochTime(final long epochTime) {
this.epochTime = epochTime;
}
}
经过尽可能深入的调试,我发现异常发生在 QueryTranslatorImpl 的 w.statement(hqlAst) 中:
private HqlSqlWalker analyze(HqlParser parser, String collectionRole) throws QueryException, RecognitionException {
HqlSqlWalker w = new HqlSqlWalker( this, factory, parser, tokenReplacements, collectionRole );
AST hqlAst = parser.getAST();
// Transform the tree.
w.statement( hqlAst );
if ( AST_LOG.isDebugEnabled() ) {
ASTPrinter printer = new ASTPrinter( SqlTokenTypes.class );
AST_LOG.debug( printer.showAsString( w.getAST(), "--- SQL AST ---" ) );
}
w.getParseErrorHandler().throwQueryException();
return w;
}
我的查询或注释有问题吗?
