使用Spring的RestTemplate获取和映射JSON内存表
使用Spring的RestTemplate获取和映射JSON内存表
提问于 2019-04-08 07:27:17
我需要映射一个JSON对象，但问题是它有一个内部自定义列表。在这种情况下，如何使用RestTemplate？
我正在尝试使用ResponseEntity和ParameterizedTypeReference，但我还没有找到解决方案。
{
"results":{
"ALL":{
"currencyName":"Albanian Lek",
"currencySymbol":"Lek",
"id":"ALL"
},
"XCD":{
"currencyName":"East Caribbean Dollar",
"currencySymbol":"$",
"id":"XCD"
},
"EUR":{
"currencyName":"Euro",
"currencySymbol":"€",
"id":"EUR"
},
"BBD":{
"currencyName":"Barbadian Dollar",
"currencySymbol":"$",
"id":"BBD"
},
"BTN":{
"currencyName":"Bhutanese Ngultrum",
"id":"BTN"
},
"BND":{
"currencyName":"Brunei Dollar",
"currencySymbol":"$",
"id":"BND"
},
"XAF":{
"currencyName":"Central African CFA Franc",
"id":"XAF"
},
"CUP":{
"currencyName":"Cuban Peso",
"currencySymbol":"$",
"id":"CUP"
},
"USD":{
"currencyName":"United States Dollar",
"currencySymbol":"$",
"id":"USD"
}
}

// you can create a custom class like below and try to map it
class NodeWrapper{
private Map<String, NodeData> results;
}
class NodeData{
private String currencyName;
private String currencySymbol;
private id;
}
// also allow nulls using object mapper annotations页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
