}

}

每写入一个服务，要添加@Autowired。JSP页面不能直接跳转，如想要跳转需要加入如下代码

@RequestMapping(value = "toPage1", method = { RequestMethod.GET, RequestMethod.POST })
public ModelAndView toPage() {
return new ModelAndView("guojia/5B");
}。其中guojia代表路径，5B代表jsp页面。

@RequestMapping("findAllEnterprise")
@ResponseBody 

其中@RequestMapping需要和前台数据如（按钮的Id）对应。
