在beforeWrite方法中的TableWriter类中设置了虚拟SQL
@Override
public void beforeWrite(List< ? extends bo > items) {
StringBuilder sb = new StringBuilder( );
if ( "DELETE".equals( NAME ) ) {
sb.append( " DELETE FROM table1 WHERE abc = ?" );
} else {
log.error( "Invalid sql [{}]", name );
}
setSql( sb.toString( ) );
}
*我的问题是我打电话时有错误
compositeWriter
但直接调用时没有错误
