Question

我尝试在互联网上发布的所有路径主要是在stackoverflow中，但是找不到我的应用程序问题的确切解决方案。

请不要将此标记为重复，因为警告可能是重复的，但版本或其他原因造成的并不重复，即相同的答案对我不起作用

警告我得到了：

WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI in DispatcherServlet with name 'appServlet'

我的控制器片段（并非我提供的所有代码，我认为这足以找到问题）

@RequestMapping(value = "/app")
@Controller
public class PersonController {

    private PersonService personService;

    @Autowired(required=true)
    @Qualifier(value="personService")
    public void setPersonService(PersonService ps){
        this.personService = ps;
    }

    @RequestMapping(value = "/persons", method = RequestMethod.GET)
    public String listPersons(Model model) {
        model.addAttribute("person", new Person());
        model.addAttribute("listPersons", this.personService.listPersons());
        return "person";
    }

和jsp代码片段是： person.jsp

<c:url var="addAction" value="/person/add" ></c:url>

<form:form action="${addAction}" commandName="person">

Answer 1

您需要在代码中添加此内容。

model.setViewName（＆＃34;人＆＃34）;

model.addAttribute（＆＃34; person＆＃34;，new Person（））;

并确保您的.jsp文件位于/ views文件夹

Answer 2

您所请求的操作未在控制器中正确映射，请尝试将其更改为 app / person / add

Spring 4.x和hibernate 4.x基本CRUD应用程序收到警告没有找到带有URI的HTTP请求的映射
