使用spring2.5+hibernate框架部署web项目后,在jsp页面请求Controller层对象,老提示WARN [PageNotFound] No mapping found for HTTP request with URI [/test/savePerson.do] in DispatcherServlet with name 'dispatcher',怎么回事?Controller层代码:
@Controller
public class PersonController {
@Resource
PersonService personService;
@RequestMapping("/savePerson.do")
public String save(Person person){
personService.save(person);
return "MyJsp";
}

检查下你的@RequestMapping("/savePerson.do")映射对着么?
