Javascript REST和JSON-使用jackson将字符串转换为JSON数组

我不熟悉JSON和REST。我正在测试一个rest API，它返回如下字符串：

[{
    "Supervisor_UniqueName": "adavis",
    "Active": "true",
    "DefaultCurrency_UniqueName": "USD",
    "arches_type": "x-zensar/primary",
    "Groups": "",
    "TimeZoneID": "US/Pacific-New",
    "UniqueName": "!!pl-10958-611879240",
    "EmailAddress": "!!pl-10958-611879240@devmail.zensar.com",
    "LocaleID_UniqueName": "en_US",
    "Name": "!!pl-10958-611879240"
}, {
    "Supervisor_UniqueName": "adavis",
    "Active": "true",
    "DefaultCurrency_UniqueName": "USD",
    "arches_type": "x-zensar/primary",
    "Groups": "",
    "TimeZoneID": "US/Pacific-New",
    "UniqueName": "!!pl-10958-789764779",
    "EmailAddress": "!!pl-10958-789764779@devmail.zensar.com",
    "LocaleID_UniqueName": "en_US",
    "Name": "!!pl-10958-789764779"
}, {
    "Supervisor_UniqueName": "adavis",
    "Active": "true",
    "DefaultCurrency_UniqueName": "USD",
    "arches_type": "x-zensar/primary",
    "Groups": "Report User",
    "TimeZoneID": "US/Pacific-New",
    "UniqueName": "105838945",
    "EmailAddress": "105838945@devmail.zensar.com",
    "LocaleID_UniqueName": "en_US",
    "Name": "105838945"
}, {
    "Supervisor_UniqueName": "adavis",
    "Active": "true",
    "DefaultCurrency_UniqueName": "USD",
    "arches_type": "x-zensar/primary",
    "Groups": "Report User, Report Manager, Report Administrator",
    "TimeZoneID": "US/Pacific-New",
    "UniqueName": "112352755",
    "EmailAddress": "112352755@devmail.zensar.com",
    "LocaleID_UniqueName": "en_US",
    "Name": "112352755"
}]

我调用rest API如下：

final ResponseEntity<String> responseEntity = restTemplate.getForEntity(resourceUrl , String.class);

final ResponseEntity ResponseEntity=restemplate.getForEntity（resourceUrl，String.class）；

其中

restemplate

属于

restemplate

我想将它们转换成一个JSON数组，访问每个JSON对象并获取每个对象的字段和值

可以用jackson来做吗？

你可以用

这是JSON的一部分：

[  
   {  
      "Supervisor_UniqueName":"adavis",
      "Active":"true",
      "DefaultCurrency_UniqueName":"USD",
      "arches_type":"x-zensar/primary",
      "Groups":"",
      "TimeZoneID":"US/Pacific-New",
      "UniqueName":"!!pl-10958-611879240",
      "EmailAddress":"!!pl-10958-611879240@devmail.zensar.com",
      "LocaleID_UniqueName":"en_US",
      "Name":"!!pl-10958-611879240"
   },
   {  
      "Supervisor_UniqueName":"adavis",
      "Active":"true",
      "DefaultCurrency_UniqueName":"USD",
      "arches_type":"x-zensar/primary",
      "Groups":"",
      "TimeZoneID":"US/Pacific-New",
      "UniqueName":"!!pl-10958-789764779",
      "EmailAddress":"!!pl-10958-789764779@devmail.zensar.com",
      "LocaleID_UniqueName":"en_US",
      "Name":"!!pl-10958-789764779"
   }
]

给你一个想法：

public MyClass {

  @JsonProperty("Supervisor_UniqueName")
  private String superVisorUniqueName;

  @JsonProperty("Active")
  private String active;

  // etc

  // getters and setters    
}

将JSON映射到您的

MyClass

：

ObjectMapper mapper = new ObjectMapper();
List<MyClass> obj = mapper.readValue(json, new TypeReference<List<MyClass>>() {});

ObjectMapper mapper=new ObjectMapper（）；
List obj=mapper.readValue（json，new TypeReference（）{}）；

您尝试了什么，得到了什么，期望得到什么，遇到了什么错误？抱歉。。我做了更多的研究，这篇文章解决了我的问题，非常感谢你的回复。恐怕我不想编写mapper类，因为它不可管理。现在使用API我得到了用户数据，像这样RESTAPI将返回不同类型的主数据（供应商、产品、商品代码、国家等）。恐怕我不能为每个人写POJO。这太过分了。你怎么认为？
