反序列化嵌套json时出现问题

json

反序列化嵌套json时出现问题,json,jackson,deserialization,Json,Jackson,Deserialization,我正在反序列化以下JSON： {"self":"http://members.cs.com/rest/api/user?username=abc@cs.com", "key":"abc@cs.com", "name":"abc@cs.com", "emailAddress":"abc@cs.com", "displayName":"ABC", "active":true, "members":{"size":1,"items":[{"name":"member-users","self":"ht

我正在反序列化以下JSON：

{"self":"http://members.cs.com/rest/api/user?username=abc@cs.com",
"key":"abc@cs.com",
"name":"abc@cs.com",
"emailAddress":"abc@cs.com",
"displayName":"ABC",
"active":true,
"members":{"size":1,"items":[{"name":"member-users","self":"http://members.cs.com/rest/api/user?username=abc@cs.com"}]},
"expand":"members"}

我创建了以下类：

@JsonIgnoreProperties(ignoreUnknown = true)
public class UserList {

private String name;
private String emailAddress;
private String displayName;
private boolean active;
List<MemberName> members = new ArrayList<>();

@JsonCreator
public UserList(@JsonProperty("name") String name, @JsonProperty("emailAddress") String emailAddress, @JsonProperty("displayName") String displayName, @JsonProperty("active") boolean active, @JsonProperty("members") List<MemberName> members) {
    this.name = name;
    this.emailAddress = emailAddress;
    this.displayName = displayName;
    this.active = active;
    this.members.addAll(groups);
    }

    //getters
}


@JsonIgnoreProperties(ignoreUnknown = true)
public class MemberName {
private String name;

@JsonCreator
public MemberName(@JsonProperty("name") String name) {
    this.name = name;
}

public String getName() {
    return name;
}

}

@JsonIgnoreProperties（ignoreUnknown=true）
公共类用户列表{
私有字符串名称；
私有字符串电子邮件地址；
私有字符串显示名；
私有布尔活动；
列表成员=新的ArrayList（）；
@JsonCreator
公共用户列表（@JsonProperty（“name”）字符串名称、@JsonProperty（“emailAddress”）字符串emailAddress、@JsonProperty（“displayName”）字符串displayName、@JsonProperty（“active”）boolean active、@JsonProperty（“members”）列表成员）{
this.name=名称；
this.emailAddress=电子邮件地址；
this.displayName=displayName；
这个.active=active；
this.members.addAll（组）；
}
//吸气剂
}
@JsonIgnoreProperties（ignoreUnknown=true）
公共类成员名{
私有字符串名称；
@JsonCreator
public MemberName（@JsonProperty（“name”）字符串名）{
this.name=名称；
}
公共字符串getName（）{
返回名称；
}
}

当我不将成员作为属性提供时，反序列化工作正常，我可以看到name、displayName、active和emailAddress的值。MemberName出现问题

有人能帮我吗？

这对我很有用：

分类项目如下：

public class Items {
    private String name;
    private String self;
    public String getName() {
        return name;
    }
    public void setName(String name) {

    }

成员类别如下：

    }
    public void setEmailAddress(String emailAddress) {
        this.emailAddress = emailAddress;
    }
    public String getDisplayName() {
        return displayName;
    }
    public void setDisplayName(String displayName) {

        this.expand = expand;
    }
}

public static void main(String[] args) throws JsonParseException, JsonMappingException, IOException {

        System.out.println(obj.getMembers().getItems().get(0).getSelf());

反序列化过程如下所示：

从XML解析是这个web API的一个选项吗？我在尝试从JSON解析时遇到了类似的问题，最终我需要切换到XML，因为它可以比JSON更显式，特别是当涉及到像这样复杂的嵌套类型时。很多时候，web API可以同时提供JSON或XML，您只需指定所需的响应类型。从XML解析不是一个选项，因为我们计划对应用程序中的所有服务调用使用通用方法。JSON的工作已经在许多其他调用中实现，我不想在这次调用中将其更改为XML。杰出的它有效地回答了许多问题。谢谢你。
