Xstream无参数构造函数错误 [英] Xstream no-args constructor error

问题描述

在尝试创建Transacao的实例时，我收到以下错误

I'm getting the following error when it tries to create an instance of 'Transacao'

`Error: Cannot construct br.com.cbmp.ecommerce.resposta.Transacao as it does not have a no-args constructor : Cannot construct br.com.cbmp.ecommerce.resposta.Transacao as it does not have a no-args constructor `

---- Debugging information ----

message : Cannot construct br.com.cbmp.ecommerce.resposta.Transacao as it does not have a no-args constructor 

cause-exception : com.thoughtworks.xstream.converters.reflection.ObjectAccessException 

cause-message : Cannot construct br.com.cbmp.ecommerce.resposta.Transacao as it does not have a no-args constructor `

class : br.com.cbmp.ecommerce.resposta.Transacao 

required-type : br.com.cbmp.ecommerce.resposta.Transacao 

path : /transacao

我知道XStream有一个错误1.3.1和JDK7，但我目前使用XStream 1.3.1和 JDK6 。

I am aware that there's a bug with XStream 1.3.1 and JDK7, but I'm currently using XStream 1.3.1 and JDK6. Any ideas why this error is still happening?

感谢

推荐答案

3解决方案：

1. 提供无参数的构造函数




3. 升级到xstream 1.4.4 *

我始终使用解决方案＃2 。

I use solution #2 all the time.

*我验证1.2.2不工作，1.4.4工作，没有尝试任何版本之间

*I verified 1.2.2 doesn't work and 1.4.4 does work, haven't tried any versions in-between
