Question

我正在使用jackson解析器来解析json。我想提取＆＃34;道具＆＃34;从JSON下面。请建议java POJO课程需要进行哪些更改才能获得＆＃34;道具＆＃34;值。下面是json和等效的POJO类。

JSON -

                            ]
                        }

JAVA POJO -

IActs.java

public class IActs
{
    private RefConfigs refConfigs;

    private String iAct;

    private Sets[] sets;

    public RefConfigs getRefConfigs ()
    {
        return refConfigs;
    }

    {
        this.refConfigs = refConfigs;
    }

    }

    @Override
    public String toString()
    {
        return "ClassPojo [refConfigs = "+refConfigs+", iAct = "+iAct+", sets = "+sets+"]";
    }
}

Sets.java

public class Sets
{
    private String id;

    private Attrs[] attrs;

    private String set;

    public String getId ()
    {
        return id;
    }

    public void setId (String id)
    {
        this.id = id;
    }

    public Attrs[] getAttrs ()
    {
        return attrs;
    }

    public void setAttrs (Attrs[] attrs)
    {

    }

    public String getSet ()
    {

    }

    public void setSet (String set)
    {
        this.set = set;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [id = "+id+", attrs = "+attrs+", set = "+set+"]";
    }
}

Attrs.java

public class Attrs
{
    private Configs configs;

    private String id;

    private String attr;

    public Configs getConfigs ()
    {
        return configs;
    }

    public void setConfigs (Configs configs)
    {
        this.configs = configs;
    }

    public String getId ()
    {
        return id;
    }

    public void setId (String id)
    {
        this.id = id;
    }

    public String getAttr ()
    {
        return attr;
    }

    public void setAttr (String attr)
    {
        this.attr = attr;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [configs = "+configs+", id = "+id+", attr = "+attr+"]";
    }
}

Configs.java

public class Configs
{
    private String iResp;

    public String getIResp ()
    {
        return iResp;
    }

    public void setIResp (String iResp)
    {
        this.iResp = iResp;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [iResp = "+iResp+"]";
    }
}

RefConfigs.java

public class RefConfigs
{
    private String[] responseTypes;

    public String[] getResponseTypes ()
    {
        return responseTypes;
    }

    public void setResponseTypes (String[] responseTypes)
    {
        this.responseTypes = responseTypes;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [responseTypes = "+responseTypes+"]";
    }
}

我尝试了几种方法，但没有一种方法可行。提前谢谢。

Answer 1

你的Set类应该有一个Attrs对象实例，而不是一个数组Attrs []。您需要更改Attrs以获得对象Attr的集合（例如）。在那个对象中你应该定义属性：id，attr，configs和props。您还需要创建一个新的Props对象。

Answer 2

只需将以下内容添加到您的Attrs课程中：

private String [] props;
public String[] getProps() {
    return props;
}
public void setProps(String[] props) {
    this.props = props;
}
