类型转换

Posted 2020-12-20 yan-sh

String 转 Map<String,Map<String,Double>>

String test;
Map<String,Map<String,Double>> map = new HashMap<>();
ObjectMapper mapper = new ObjectMapper();
try{
  map = mapper.readValue(tset,new TypeReference<Map<String,Map<String,Double>>>(){});
}catch(Exception e){
    e.printStackTrace();
}
