Spring servlet 映射不起作用

Question

当我尝试加载 http://localhost:8080/people 时，我收到 404 页面未找到错误。

这是我在 web.xml 中的 servlet 映射:

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/people/*</url-pattern>
</servlet-mapping>

我的理解是这样的:

对 http://localhost:8080/people 的 url 请求将被 servlet“spring”拦截并调用类 org.springframework.web.servlet.DispatcherServlet 这是正确的吗？

我是否需要一些额外的配置才能正确加载此类？

更新:

这是 Controller :

@Controller
public class PersonController {

    @Autowired
    private PersonService personService;

    @RequestMapping("/")
    public String listPeople(Map<String, Object> map) {

        map.put("person", new Person());
        map.put("peopleList", personService.listPeople());

        return "people";
    }

    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public String addPerson(@ModelAttribute("person") Person person, BindingResult result) {

        personService.addPerson(person);

        return "redirect:/people/";
    }

    @RequestMapping("/delete/{personId}")
    public String deletePerson(@PathVariable("personId") Integer personId) {

        personService.removePerson(personId);

        return "redirect:/people/";
    }
}

Answer 1

你有 controller 来支持你的 GET 响应吗？

像这样

@Controller
@RequestMapping(value = "/people")
public class LoginController {

    @RequestMapping(value = "/i_am_here", method = RequestMethod.GET)
    public String firstForm() {
        return "SHOW_ME_THE_JSP_PAGE";
    }
}

基于上面的示例，这将使您的获取 URL 请求类似于 ->/people/i_am_here

方法将被调用，响应可以在 JSP 中发回。
