public String execute() throws Exception {
try{

u.setUsername(user.getUsername());
u.setPassword(user.getPassword());
u.setEmail(user.getEmail());
userService.saveUser(u);
}
catch(Exception e)
{
e.printStackTrace();
}
return SUCCESS;
}
}
我调过了就是execute里的userService是空的求大神指点！！！
没有初始化，肯定为空
public void setUserService(UserService userService) { this.userService=userService; }
这句话在外边调用过不？没有吧追问
这不是调用的，是用来给spring框架来注入的stter方法
追答但是你在外边没注入，那这个变量肯定是空的。
