在beforeWrite方法中的TableWriter类中设置虚拟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( ) );
}
*我的问题是我在通话时遇到错误
compositeWriter
但直接调用时没有错误
writer1 *
组块
<chunk reader="reader" writer="compositeWriter/writer1" commit-interval="10" />
