将plist格式文本转换为json格式

Question

应用程序使用Apache Cayenne。

我收到以下格式的字符串。这个字符串也适用于我的HashMap格式。

{And=[(effectiveDate >= Tue Sep 01 00:00:00 EDT 2015), {And=[(loanType = 2), {Or=[{And=[{Not=[(specialFeaturesString like "*003* ")]}, {Not=[(specialFeaturesString like "*007*")]}]}, (specialFeaturesString like "*007*")]}, (specialFeaturesString like "*808*")]}]} 

我想隐蔽上面的字符串，以JSON格式像下面

{ "condition": "AND", "rules": [ { "id": "eDate", "field": "eDate", "type": "date", "input": "text", "operator": "greater_or_equal", "value": "2015/09/01" }, { "condition": "AND", "rules": [ { "id": "loanType", "field": "loanType", "type": "string", "input": "text", "operator": "equal", "value": "2" }, { "condition": "OR", "rules": [ { "id": "specialFeatureText", "field": "specialFeatureText", "type": "string", "input": "text", "operator": "equal", "value": "*707*" }, { "condition": "AND", "rules": [ { "id": "specialFeatureText", "field": "specialFeatureText", "type": "string", "input": "text", "operator": "not_equal", "value": "*003*" }, { "id": "specialFeatureText", "field": "specialFeatureText", "type": "string", "input": "text", "operator": "not_equal", "value": "*007*" } ] } ] }, { "id": "specialFeatureText", "field": "specialFeatureText", "type": "string", "input": "text", "operator": "equal", "value": "*808*" } ] } ] } 

我可能会通过地图创建POJO和循环来实现这一目标。也许涉及一些递归。

我最终将上面的json提供给jQuery querybuilder。

谢谢你的帮助。

您可以使用Jackson JSON序列化器以适当的格式将您的HashMap或POJO转换为JSON。例如： -

Map<String, Object> mapMatchingJsonStructure = ... 
OutputStream out = // where you want to write the output 
new ObjectMapper().writeValue(out, mapMatchingJsonStructure); 

而且卡宴在cayenne-wocompat一个的plist解析器。这与你无关，因为你已经解析了你的plist。但我想我会提到。
