[英]Controller method not getting called in spring mvc
我正在修改在特定站点上找到的项目。 问题是当我在服务器上运行项目时,显示的home.jsp页面包含美国地图。 我已经使地图可点击。当我点击地图状态时,生成的新URL为localhost:7001/SpringMVCAngularJS/home.jsp?statechoice=ME
。根据spring mvc逻辑,应调用getUSCity()方法。 但是它没有被调用。 即使我只访问localhost:7001/SpringMVCAngularJS/home.jsp
,它也不会被调用。 而如果我点击localhost:7001/SpringMVCAngularJS/springAngularJS.web
,则将调用特定方法。 你能告诉我我是否缺少任何映射。
@Controller
public class SpringMVCController {
@Autowired
Top10LanesService lanesService;
@RequestMapping(value = "/angularJS.web", method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
return "Home";
}
@RequestMapping(value = "/springAngularJS.web", method = RequestMethod.GET, produces = { "application/xml",
"application/json" })
public @ResponseBody List<LmWebShipment> getTop10Lanes() {
List<LmWebShipment> al = new ArrayList<LmWebShipment>();
// Top10LanesDAOImpl top10LanesDaoImpl = new Top10LanesDAOImpl();
al = lanesService.getTop10Lanes();
return al;
}
// Called on Click of US state
@RequestMapping(value = "/home.web", method = RequestMethod.GET, produces = { "application/xml",
"application/json" })
@ResponseBody
public void getUSCity(@PathVariable("statechoice") String statechoice) {
System.out.println("In getUSCity" + statechoice);
}
}
我的home.jsp文件中有类似的内容。
<area shape='polygon' coords='489,52,502,31,513,32,518,54,490,71' href='home.jsp?statechoice=ME' target="right" alt='Maine'>

根据春季的路径变量概念,应如下所示。您在url中缺少路径变量
@RequestMapping(value = "/home.web/{statechoice}", method = RequestMethod.GET, produces = { "application/xml",
"application/json" })
@ResponseBody
public void getUSCity(@PathVariable("statechoice") String statechoice) {
System.out.println("In getUSCity" + statechoice);
}
根据春季语法,您应该输入的URL是localhost:7001 / SpringMVCAngularJS / home.web / ME。其中ME是您将在状态选择中获得的值。
