Java json数组到bean（对象映射器）

读取json对象并通过创建新的getter n setter存储到bean中。我想从下面读取作为字符串接收的json对象的粗体值

[{"country":"**India**","provinces":[{**"province":"India","confirmed":265928,"recovered":129095,"deaths":7473,"active":129360**}],"latitude":20.593684,"longitude":78.96288,"date":"2020-06-08"}]

我能够成功地读取国家/地区，但我想读取上面用粗体显示的其他值，这些值应该包含属性

省份
，必须是另一个具有您想要的属性的Bean。就这么简单

看看代码：

@JsonIgnoreProperties(ignoreUnknown = true)
public class CoronaBean {
private String country; 
private ProvinceBean[] provinces
...getters and setters

} 

@JsonIgnoreProperties(ignoreUnknown = true)
public class ProvinceBean {
private Integer confirmed;
private Integer recovered;
...rest you want and getters and setters

我想你也可以查看这个问题，了解更多细节和实现所需的方法：

ObjectMapper mapper = new ObjectMapper();
        try {
            CoronaBean[] coronaBean = mapper.readValue(json, CoronaBean[].class);
            for(CoronaBean c: coronaBean ){
            System.out.println(c.getCountry());
            }
        } catch (JsonProcessingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

@JsonIgnoreProperties(ignoreUnknown = true)
public class CoronaBean {
private String country; 
private ProvinceBean[] provinces
...getters and setters

} 

@JsonIgnoreProperties(ignoreUnknown = true)
public class ProvinceBean {
private Integer confirmed;
private Integer recovered;
...rest you want and getters and setters
