Question

struts2和easyui实现一个datagrid问题。

index.jsp

<script type="text/javascript">
$("document").ready(function(){
$("#dg").datagrid({
url:'crudAction.action',
columns:[[{
field:'uid',
title:'ID',
width:100
},{
field:'userName',
title:'用户名',
width:100
},{
field:'passWord',
title:'密码',
width:100
}]]
});
});
struts.xml
<package name="json" namespace="/" extends="json-default">
<action name="crudAction" class="com.wky.action.ControlAction" method="getList">
<result type="json" name="success">
<param name="root">responseJson</param>
</result>
</action>
</package>
java

public class ControlAction extends ActionSupport{
public Map responseJson;
public Map getResponseJson() {
return responseJson;
}
public void setResponseJson(Map responseJson) {
this.responseJson = responseJson;
}

public String getList(){
Map<String, Object> map = new HashMap<String, Object>();
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
for(int i=0;i<3;i++){
Map<String, Object> m = new HashMap<String, Object>();
m.put("id", i);
m.put("name", "Mic"+i);
m.put("password","password"+i);
list.add(m);
}
map.put("rows", list);
map.put("totalCont", 3);
System.out.println("1222131111111111111111111111111111112");
this.setResponseJson(map);
return Action.SUCCESS;
}
老是提示
There is no Action mapped for namespace / and action name crudAction. - [unknown location]

Answer 1

<action name="crudAction" class="com.wky.action.ControlAction" method="getList">

class路径正确吗？你可以按着ctrl键鼠标悬浮到这个路径上看有没有下划线没有的话表示路径不正确
