Question

我已将spring framework 3用于我的应用程序。开发中的一切都很好 Netbeans但我需要一个自定义构建并完成相同的构建创建没有任何问题，但我得到以下错误调用以下方法时发生错误

@RequestMapping(value = "/security/login", method = RequestMethod.POST)
public ModelAndView login(@RequestParam String userName, @RequestParam String password, 
    HttpServletRequest request) {
    ......................

但是在用netbeans创建战争时没有问题（我确定这是关于编译问题）你对这个问题有任何经验吗？还有任何额外的javac参数用于编译相同的（netbeans用于编译时使用自定义任务）

输入例外报告

参数名称仅在以调试模式编译时才存储在已编译的代码中，因此您应该在调试模式下编译它，或者使用显式参数名称提供@RequestParam。后一种方法更可靠，因为它不依赖于环境：

@RequestMapping(value = "/security/login", method = RequestMethod.POST) 
public ModelAndView login(@RequestParam("userName") String userName, 
    @RequestParam("password") String password,  
    HttpServletRequest request) { 
    ......................
