如何使用Jackson /其他库将json响应对象映射到首选格式？(How to map json response object to a preferred format using Jackson / other library?)
如何使用Jackson /其他库将json响应对象映射到首选格式？(How to map json response object to a preferred format using Jackson / other library?)
我从第三方Web服务获得以下JSON响应格式：
{ "meta": { "code": 200, "requestId": "1" }, "response": { "locations": [ { "id": "1", "name": "XXX", "contact": { phone: '123', email: 'abc' }, "location": { "address": [ "Finland" ] } }, { // another location } ] } }以下是我应该从我自己的Web服务返回的内容：
[ { "id": "1", "name": "XXX", "phone": '123', "address": "Finland" }, { // another location } ]我该怎么办？ 我已经阅读了一些关于杰克逊的好东西，但是只有几个简单的例子，你将一些简单的JSON obj映射到POJO。 在我的例子中，我需要删除一些节点，并在层次结构中更深入地遍历以获取嵌套值。 到目前为止，这是我的春季启动应用中的宝贝步骤：
@GET @Path("{query}") @Produces("application/json") public String getVenues(@PathParam("query") String query){ return client.target(url).queryParam("query",query).request(...).get(String.class) }任何帮助，指针，建议都欢迎！
I am getting the below JSON response format from a third party web service:
{ "meta": { "code": 200, "requestId": "1" }, "response": { "locations": [ { "id": "1", "name": "XXX", "contact": { phone: '123', email: 'abc' }, "location": { "address": [ "Finland" ] } }, { // another location } ] } }And here is what I should return as a response from my own web service:
[ { "id": "1", "name": "XXX", "phone": '123', "address": "Finland" }, { // another location } ]What should I do? I've read some good stuff about Jackson but there are only a few simple examples where you map some simple JSON obj as is to POJO. In my case, I need to remove a few nodes, and also traverse deeper down the hierarchy to get the nested value. This is my baby step so far in my spring boot app:
@GET @Path("{query}") @Produces("application/json") public String getVenues(@PathParam("query") String query){ return client.target(url).queryParam("query",query).request(...).get(String.class) }Any helps, pointers, recommendations are welcomed!

我把你的代码弹出一个编辑器来试一试。
我想你想要根据你的需要做一些改变。
nav ul li ul { display: none; } nav ul li:hover > ul { display:block; position:absolute; top: 100%; left: 0; } nav ul li { position: relative; }这将使下拉显示在正确的位置。 他们仍然需要造型但
position:absolute与相对容器阻止他们影响周围的布局，我相信你想要的。希望能帮到你！
注意::您可以看到更改如何影响以下代码段。

I think you're looking to make slight changes for what you need.
nav ul li ul { display: none; } nav ul li:hover > ul { display:block; position:absolute; top: 100%; left: 0; } nav ul li { position: relative; }This will make the drop downs appear in the right position. They will still need styling but
position:absolutewith a relative container stops them from affecting the surrounding layout which is I believe what you desire.Hope that helps you out!
NOTE:: You can see how the changes affect with the following snippet.
