标 题: 一个简单问题：No result defined for action com.beijing.ac.DataAction and result update
发信站: 水木社区 (Fri Sep 4 20:56:02 2015), 站内
在update.jsp页面
调用Data_save时没问题
调用 data!update.action没问题
但调用 Data_update时就出现
No result defined for action com.beijing.ac.DataAction and result
update
说是找不到update这result,太奇怪了
数据类型应该没问题啊，应该不会存在数据转换问题吧
我在package也加上namespace上了（不加也是相同的错误）
还会有啥问题可能引起的呢？
下面是struts.xml内容
<struts>
<package name="test" extends="struts-default"
namespace="">
<action name="data"
class="com.beijing.ac.DataAction">
<result
name="findById">/update.jsp</result>
<result name="update"
type="redirectAction">/Data_find.action</result>
</action>
<action name="*_*" class="com.beijing.ac.
{1}Action" method="{2}">
<result name="input">/input.jsp</result>
<result name="save"
type="redirectAction">/Data_find.action</result>
<result name="update"
type="redirectAction">/Data_find.action</result>
<result name="delete"
type="redirectAction">/Data_find.action</result>
<result name="find">/{2}.jsp</result>
</action>
</package>
</struts>
下面是DataAction.java代码
public class DataAction extends ActionSupport {
//biz接口的声明，用来调用biz
IDataBiz idata;
//这些对象set和get后，都会被hibernate自动放进request里
private Integer daId;
private String daName;
private String daAge;
private List<Datas> datas;
private Datas data;
private int nowPage = 1;
private int pageSize = 5;
private int pageCount;
private int count;
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
public int getNowPage() {
return nowPage;
}
public void setNowPage(int nowPage) {
this.nowPage = nowPage;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public int getPageCount() {
return pageCount;
}
public void setPageCount(int pageCount) {
this.pageCount = pageCount;
}
public List<Datas> getDatas() {
return datas;
}
public void setDatas(List<Datas> datas) {
this.datas = datas;
}
public IDataBiz getIdata() {
return idata;
}
public Integer getDaId() {
return daId;
}
public void setDaId(Integer daId) {
this.daId = daId;
}
public String getDaName() {
return daName;
}
public void setDaName(String daName) {
this.daName = daName;
}
public String getDaAge() {
return daAge;
}
public void setDaAge(String daAge) {
this.daAge = daAge;
}
public void setIdata(IDataBiz idata) {
this.idata = idata;
}
public String save(){
System.out.println("----------------");
System.out.println("save");
data = new Datas();
data.setDaId(daId);
data.setDaAge(daAge);
data.setDaName(daName);
idata.save(data);
System.out.println("保存成功");
return "save";
}
public String delete(){
System.out.println("delete");
System.out.println(daId);
data = new Datas(daId);
idata.delete(data);
return "delete";
}
public String update(){
System.out.println("update");
data = new Datas(daId,daName, daAge);
idata.update(data);
System.out.println("update成功");
return "update";
}
public String findById(){
System.out.println("findById");
data= idata.findById(daId);
daAge = data.getDaAge();
daName = data.getDaName();
daId = data.getDaId();
return "findById";
}
}
下面是update.jsp代码
