Answer 1

你用的是struts2怎么不指定你的action的方法呢？？？

Answer 2

在配置时不指定方法，就采购用默认方法的execute(),哎，只能上网，Q，msn,skype，都不上了！！！ 
@Override
 public String execute() throws Exception {
 System.out.println("test");
  boolean flag = false;
  flag = userDaoImpl.insertUser(user);
  if(flag){
   return SUCCESS;
  }else{
   return ERROR;
  }
 }

Answer 3

<action name="reg" class="reg">
没有设置method，默认就执行public String execute()方法～

Answer 4

试了。还是不行。换成add方法试了。
<package name="default" extends="struts-default">
  <action name="reg" class="reg" method="add">
   <result name="success">/regSuc.jsp</result>
   <result name="error">/regFail.jsp</result>
  </action>
 </package>
public String add() {
  System.out.println("asg");
  return "success";
  }

Answer 5

你有没有修改，方法或者Action的名称？  你是怎么样访问的，代码贴出来。

Answer 6

根据程序走的流程，我贴出代码。
jap提交表单
<form action="reg.action" method="get">
     用户名：<input type="text" name="user.username" /><br />
     密&nbsp;&nbsp;码：<input type="password" name="user.password"><br />
     <input type="submit" value="注册" /><input type="reset" value="重置" />
    </form>struts.xml
 <package name="default" extends="struts-default">
  <action name="reg" class="reg" method="add">
   <result name="success">/regSuc.jsp</result>
   <result name="error">/regFail.jsp</result>
  </action>
 </package>application.xml
 <bean name="reg" class="com.test.action.UserAction" scope="prototype">
  <property name="userDaoImpl" ref="userDaoImpl"></property>
 </bean>action动作处理类
@Override
 public String execute() throws Exception {
 System.out.println("test");
  boolean flag = false;
  flag = userDaoImpl.insertUser(user);
  if(flag){
   return SUCCESS;
  }else{
   return ERROR;
  }
 }
 
  public String add() {
  System.out.println("asg");
  return "success";
  ｝默认方法和用add方法，都试过了。还是报错！

2011-12-15 14:15:09,233 WARN [org.apache.struts2.dispatcher.Dispatcher] - Could not find action or result
There is no Action mapped for namespace / and action name reg. - [unknown location]已经告诉你了
可能是你页面的jsp所访问的action路径写错了把字贴出来 要不就是你这个struts文件没有和被使用

Answer 8

HTTP Status 404 - There is no Action mapped for namespace / and action name reg.
<form action="reg.action" method="get">
改成<form action="reg" method="get">或者  action="${上下文路径}/reg"

Answer 9

你怎么样访问的？ http：//   ？？？？

Answer 10

访问url: http://localhost:8080/ssh1/reg.jsp
提交之后http://localhost:8080/ssh1/reg?user.username=34523&user.password=

Answer 11

他是叫你修改form表单的提交方式
<form action="reg" method="get">或者 action="${上下文路径}/reg"

Answer 12

你有没有加struts2-spring-xxx.jar包？？

Answer 13

你有没有加struts2-spring-plugin-xxx.jar包？？
在struts lib目录下

Answer 14

Answer 15

application配置 去掉scope="prototype
 <bean name="reg" class="com.test.action.UserAction">
  <property name="userDaoImpl" ref="userDaoImpl"></property>
 </bean>

Answer 16

你的lib里面是否包含了 antlr-2.7.6.jar 和antlr-2.7.2.jar，这两个只能留一个antlr-2.7.6.jar
