Java 使用SpringRESTTemplate使用分页API

我想使用分页的API。该API由使用SpringBoot创建的端点提供。在寻找解决方案时，我在StackOverflow上找到了一篇文章

几乎每个答案都建议创建一个要解析的POJO。但由于这是一个标准问题，因此应该有一个由框架支持的标准解决方案。在上面提到的帖子中有一个作者的答案。他建议使用

参数化TypeReference

。为了我的目的，我把他的剪子剪了下来，并改变了类型

T

：

restTemplate.exchange(targetUrl, HttpMethod.GET, requestEntity, new ParameterizedTypeReference<PagedResources<String>>() {});

这让我们了解了底层数据结构，如下所示

<200,
{
   "content":[
      "Data1",
      "Data2",
      "Data3"
   ],
   "pageable":{
      "sort":{
         "sorted":false,
         "unsorted":true,
         "empty":true
      },
      "offset":0,
      "pageSize":20,
      "pageNumber":0,
