我现在直接调用 deleteWith(obj,regex) 传入对象和需要删除@Many 字段的正则，发现没有进行关联删除。

是必须先调用fetchLinks(obj,regex)之后，再调用deleteWith(obj,regex) 才能进行关联删除么？
大神不对呀，fetchLinks之后 ，deleteWith还是不起作用呀
fetchLinks 后 obj 里面有@Many 的对象，
但是deleteWith 源码里面
public int deleteWith(Object obj, final String regex) {
if (null == obj)
return 0;
final int[] re = new int[1];
Lang.each(obj, false, new Each<Object>() {
public void invoke(int index, Object ele, int length) throws ExitLoop, ContinueLoop,
LoopException {
EntityOperator opt = _optBy(ele);
if (null == opt)
return;
opt.entity.visitMany(ele, regex, doDelete(opt));
opt.entity.visitManyMany(ele, regex, doClearRelationByLinkedField(opt));
opt.entity.visitManyMany(ele, regex, doDelete(opt));
opt.addDeleteSelfOnly();
opt.entity.visitOne(ele, regex, doDelete(opt));
re[0] += opt.exec().getUpdateCount();
}
});
return re[0];
走到re[0] += opt.exec().getUpdateCount(); 时候，看到ele对象 里面 @Many的对象依然为空
