<form action="user.action" method="get">
name<input type="text" name="username"/><br />
pass<input type="password" name="pass" /><br />
check<input type="password" name="check"><br />
<input type="submit" value="submit">
</form>
在Action里是用User user
@Override
public String execute() throws Exception {
user.setUsername(user.getUsername());
user.setPassword(user.getPassword());
return "success";
}
然后报空指针异常
处理：
在表单改为
name<input type="text" name="user.username"/><br />
pass<input type="password" name="user.pass" /><br />
