我尝试使用Gson解析我的Tools类。问题是当我运行单元测试时，toolConverted有空的ToolA和ToolB。字符串本身是一个有效的JSON字符串，我认为问题可能出在www.example.com类中的构造函数上Tools.java。
Tools.java

@Getter
@AllArgsConstructor
@NoArgsConstructor
public class Tools{
    @JsonProperty("ToolA")
    List<ToolA> toolA;

    @JsonProperty("ToolB")
    List<ToolB> toolB;
}

ToolA.java

@Getter
@AllArgsConstructor
public class ToolA{
    String uxA;
    String uxB;
    String uxC;
    String uxD;
}

转换

Gson gson = new Gson();
JsonMapper jsonMapper = JsonMapper.builder().build();
String toolsValue= jsonMapper.writeValueAsString(TOOLS_MAP);
Tools toolConverted = gson.fromJson(toolsValue, Tools .class);

工具值

{
   "ToolA":[
      {
         "uxA":"7",
         "uxB":"234.53",
         "uxC":"5345.23",
         "uxD":"0.155"
      }
   ],
   "ToolB":[
      {
         "state":"AZ",
         "compound_tax":"N",
         "federal_tax_percent":"5.0000",
         "provincial_tax_percent":"0.0000"
      }
   ]
}
