spring-mongo-template中对内嵌集合对象 不定参数的查询

测试数据：

{
  "_id" : ObjectId("54c752ed5c01557fc2eba8f1"),
  "title" : "测试1,27",
  "products" : [{
      "name" : "石油",
      "classid" : "001",
      "status" : "1",
      "isorg" : "Y",
      "_class" : "jyd.info.article.model.Customization"
    }],
}

{
  "_id" : ObjectId("54c755f34c2815a1467c5391"),
  "title" : "测试多产品",
  "products" : [{
      "name" : "nn油",
      "classid" : "001002",

需要的接口：

List

selectByParas(String[] products,String columnId);

接口实现：

	@Override
	public List
 selectByParas(String[] products, String columnId) {
		Query query = new Query();
		Criteria c = new Criteria();
		Criteria[] c1 = new Criteria[products.length+1];
		for(int i=0;i
