Apache Tomcat/5.5.17 --------------------编程问答-------------------- 500 服务器错误. 是个大的统称,什么原因都有可能.
org.apache.jasper.JasperException: Incorrect result size: expected 1, actual 2
这里给出了错误原因了.看下是不是你的sql有问题,或者调用执行sql的方法有问题.sql返回结果可能是个list,但调用的方法不是获得list --------------------编程问答--------------------
那个错误怎么看呢 --------------------编程问答--------------------
怎么都没人回帖呢？这个网站人气不高吗？
