如何拆分两个 json 字符串

Question

我有一个字符串，但 它包含两个对象，如下所示 {"firstName":"A","lastName":"Z"}{"firstName":"B","lastName":"Y"} 我得到了这个字符串作为响应，但我想一个一个地处理它，所以我应该如何将这个字符串分开，比如 {"firstName":"A","lastName":"Z"} 和 {"firstName":"B","lastName":"Y"}

Answer 1

Object mapper = new ObjectMapper();   
 List<YourClass> ls= ((ObjectMapper) mapper).readValue(
                    "[{"firstName":"A","lastName":"Z"},{"firstName":"B","lastName":"Y"}]",
                    new TypeReference<List<YourClass>>() {
                    });
//process list.

YourClass 映射 json 输入的 class。希望这就是您要找的。

编辑：

由于您的输入是以 {"firstName":"A","lastName":"Z"}{"firstName":"B","lastName":"Y"} 方式收到的，因此

String input = "{\"firstName\":\"A\",\"lastName\":\"Z\"}{\"firstName\":\"B\",\"lastName\":\"Y\"}";

String array[] = input.split("(?=\{)|(?<=\})");

System.out.println(array[0]);
System.out.println(array[1]);

输出：

{"firstName":"A","lastName":"Z"}
{"firstName":"B","lastName":"Y"}
