配置文件都没错tomcat运行没问题
运行index.jsp没错
其中代码：
...
<body>
<form action="action" method="post">
<input type="text" size="5" name="clazz">
<input type="button" value="点击" onclick="this.form.submit();">
</form>
</body>
...
点击按钮跳转就出错了
action代码testaction.jsp
import com.opensymphony.xwork2.ActionSupport;
public class testaction extends ActionSupport{
/**
* @param args
*/
private String clazz;
testService service;
public String getClazz() {
return clazz;
}
public void setClazz(String clazz) {
this.clazz = clazz;
}
public void setService(testService service) {
this.service = service;
}
public String count(){
System.out.println(clazz);
service.countService();
return "result";
}
}
testService .jsp代码：
package com.aaa.service;
import com.aaa.DAO.BaseDAOImpl;
public class testService {
/**
* @param args
*/
BaseDAOImpl dao;
public BaseDAOImpl getDao() {
return dao;
}
public void setDao(BaseDAOImpl dao) {
this.dao = dao;
}
public void countService(){
dao.test();
}
}
BaseDAOImpl .jsp
中test方法：
public void test(){
System.out.println("124343546");
}
求助啊...整了两天了 急啊..... --------------------编程问答-------------------- 看看你spring和struts的相关配置 --------------------编程问答-------------------- 没有用struts.xml的配置文件吗？ --------------------编程问答-------------------- public String count(){
System.out.println(clazz);
service.countService();
return "result";
}
是進入count方法后才報的找不到countService方法，看看service對象類中有沒有定義好，及其他各種定義 --------------------编程问答-------------------- <body>
<form action="action" method="post">
<input type="text" size="5" name="clazz">
<input type="button" value="点击" onclick="this.form.submit();">
</form>
</body>
form中的action中的参数，是你配置文件中action的标示吗？ --------------------编程问答-------------------- 严重怀疑楼主的testService类文件没有更新，可能countService()是后加的，但重新编译后的class没有update
补充：Java , Web 开发
