Question

I m having a strange problem with Spring MVC. I have a simple controller like this:

@Controller
@RequestMapping("admin")
public class AdminController {

@RequestMapping(value = "", method = RequestMethod.GET)
public String home() {
    return "home";
}

当我管理我的服务器和接驳机时:地方厅/行政部有404个错误。这一观点已经存在,应当提供。当我检查我的春季事件记录时,情况是:

一切都得到正确处理,但并非只是表明观点,而是发送者Servlet向要求查阅的词库提出新的GET申请。

Answer 1

这一切之后,这是一个与散射有关的问题。由于某种原因,我重新调整了我民主选举学会的组合,这一错误得到了解决。感谢您的帮助。

Answer 2

@Controller
@RequestMapping("admin")
public class AdminController {

@RequestMapping(method = RequestMethod.GET)
public String home() {
    return "home";
}

remove value property of @RequestMapping for home() function.

Answer 3

I think this is servlet mapping problem in web.xml. Change it in web.xml to /admin addreses only. Perhaps now you have:

<url-pattern>*</url-pattern>

change it to:

<url-pattern>/admin/*</url-pattern>

Answer 4

要求绘制你方法的说明,限制了你的控制者回应从“行政/家庭”开始的要求。

I would apply the following modifications :

@Controller
@RequestMapping("/admin")
public class AdminController {

   @RequestMapping(method = RequestMethod.GET)
   public String home() {
      return "home";
   }
}

Answer 5

引证:

@RequestMapping(value = "admin",
        method = {RequestMethod.GET, RequestMethod.POST })
