@Controller@RequestMapping("/em_info")public class Em_infoController { @Autowired private IEm_infoService em_infoService; @RequestMapping("/findAll.do") public ModelAndView findAll() throws Exception{ ModelAndView mv =new ModelAndView(); List<Em_info> em_infoList = em_infoService.findAll(); for (Em_info em:em_infoList ) { System.out.println(em.getEm_name()); } mv.addObject("em_infoList",em_infoList); mv.setViewName("em_info"); return mv; }} |
4、页面：
Index.Jsp 添加超连接

|
<a href="${pageContext.request.contextPath}/em_info/findAll.do">查询所有</a> |
创建结果展示页面em_info.jsp
通过${em_infoList}EL表达式获取值，并表格通过foreche循环展现数值
把项目web的war包部署到tomcat
