struts2使用json返回数据，报错：Parent package is not defined: json-default - [unknown location]

使用struts2的struts-json插件时,一直报错:找不到json-default的位置,下面是我的查错步骤: 1.将struts-json版本更改为低版本,结果还是报这个错 2.重新导入maven依赖,还是不行 3.查看struts-json包内的struts-plugin.xml是否有json-default的package以及json的结果类型,发现有. 4.静下心想了一下整个package的调用过程,都找不到原因 5.最后怀疑是war包的问题,war包内没有这个jar包,打开wa

新装了VMWare Player,结果装上Ubuntu12.04后安装软件都提示:Unable to locate package错误,解决方法非常简单,终端输入以下命令即可: [cpp] view plaincopy sudo apt-get update 究其原因,应该是刚安装,软件源还来不及更新,所以才会无法找到包.我猜测在更换软件源之后,也很可能会出现这个问题. Unable to locate package错误解决办法,布布扣,bubuko.com
