java json转map

1. 单 示例：

String str = "{\"C\":\"1006\",\"N\":\"玫瑰\"}"

转：

Map<String, String> maps = new HashMap<>()

def xtr = objectMapper.readValue(str, Map.class)

 

 

2. 多 示例： 

def flistjson= "[{\"C\":\"1006\",\"N\":\"牡丹\"},{\"C\":\"1007\",\"N\":\"葡萄\"},{\"C\":\"1008\",\"N\":\"玫瑰\"}"

if (deptlistjson){

    JavaType javaType = objectMapper.getTypeFactory().constructParametricType(ArrayList.class, Map.class)
    ArrayList<Map<String,String>> flowlist=objectMapper.readValue(flistjson, javaType) as ArrayList<Map<String,String>>;
    for (def f : flistjson){
        String code=f("C")
        if (code.contains("-")){
            String[] codes=code.split("-")
        }
    }
}
