ajax请求

异步请求时后台访问不到
控制类加注解@ResponseBody 参数加注解@Param或@RequestParam

    @RequestMapping(value = "/checkName")
    @ResponseBody
    public boolean checkNamee(@Param(value = "name") String name,
            @Param(value = "code") String code) {
        List<LogisticsBatchDto> count = null;
        if (name != null && code == null) {
            count = logisticsBatchServicelmpl.selectByName(name, code);
            if (count.size() == 0) {
                return true;
            }
        }
