JsonMapper json字符串转对象

public static <T> T jsonToBean(String json,Class<T> tClass){
        try {
            //可以转换单引号
            mapper.configure(JsonParser.Feature.ALLOW_SINGLE_QUOTES,true);
            //键可以不用引号包裹
            mapper.configure(JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES,true);
            return mapper.readValue(json,tClass);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
        return null;
    }
