Struts2+Spring+Hibernate页面访问异常

Question

我是用一个add.jsp来添加信息，然后跳转到list.jsp显示。现在add.jsp页面可以正常显示，但是点击submit后就出现错误信息：
HTTP Status 404 - /jwc/stu/list.action--------------------------------------------------------------------------------type Status reportmessage /jwc/stu/list.actiondescription The requested resource (/jwc/stu/list.action) is not available.
--------------------------------------------------------------------------------Apache Tomcat/6.0.29为什么list.action找不到呢？我的struts.xml如下：<?xml version="1.0" encoding="UTF-8"?>

Answer 1

struts2在重定向到另一个action时,需要设置type="redirect",如你的:
<action name="add" class="addBean" method="add">
<result>list.action</result>
</action>
应该设置为:
<action name="add" class="addBean" method="add">
<result type="redirect">list.action</result>
</action>

Answer 2

试一下<result type="chain">list</result> or <result type="chain">list.action</result>

--------------------------------------------------------------------------------Apache Tomcat/6.0.29查询数据库信息是写进去了，但是list就是出不来

Answer 4

 com.bit.jwc.action.StudentAction.list()jar冲突吗？

Answer 5

java.lang.NoSuchMethodException: com.bit.jwc.action.StudentAction.list()
找不到这个action的方法
有可能是tomcat发布了两个s2sh项目，将其余的项目给删掉

Answer 6

java.lang.NoSuchMethodException
包无法读取到，重新生成还是这样吗？

Answer 7

我就一个项目额jar冲突？具体是什么呢？add是可以写进数据库的，就是list让他显示的时候就出问题了这两个应该是平行的啊，怎么会一个可以一个有问题呢

Answer 8

OK,终于解决了，确实有个jar包冲突了，还有个大小写的问题初学好多东西搞不明白额谢谢各位了~~
