databean已用static修饰

使用版本： 'com.alibaba:fastjson:1.1.67.android'

加个自定义函数即可

ContradictionDetailBean$DataBean 我也遇到这个问题,在类里面如果还包含一个类的话,内部类需要创建一个空的构造函数,不然的话就会报这个错误 @wenshao @bwzhny 这个应该可以优化的把... 使用版本： 'com.alibaba:fastjson:1.1.67.android' Gson不会有这个问题.....不过我还是喜欢用国内的

DataBean的代码是怎样的？

wenshao

import com.chad.library.adapter.base.entity.MultiItemEntity;

public class ShopBean implements Serializable { ... private List dataList; public class ItemBean implements MultiItemEntity, Serializable { } } @wenshao

sweet2o09

JSON.parseObject(json, ShopBean .class)就会提示default constructor not found

sweet2o09

我发现了问题所在了,我这边是在ItemBean里面创建了一个传参的构造函数,导致的default constructor not found,如果我不创建构造函数或者是多创建一个空的构造函数,都不会出现问题了

public class ItemBean implements MultiItemEntity, Serializable {
    public ItemBean (int itemType) {
            this.itemType = itemType;
        }
}

不知道这个算不算bug @wenshao

@sweet2o09 请问您遇到的问题解决了吗？我这边也遇到内部类中存在有参构造方法时，会导致default constructor not found 错误日志： com.alibaba.fastjson.JSONException: default constructor not found. class java.util.Collections$UnmodifiableMap at com.alibaba.fastjson.util.JavaBeanInfo.build(JavaBeanInfo.java:467) at com.alibaba.fastjson.util.JavaBeanInfo.build(JavaBeanInfo.java:213)

加一个空的构造方法就好吧
