Spring MVC返回視圖url的構建不正確

Question

以下具有pom.file的應用程序使用Spring Boot & Spring MVC & Rest模板。如果我部署的應用程序（或同春啓動Application.java類開始），然後導航到http://localhost:8080/app-name/user/{userID}然後我得到這個異常：

HTTP狀態404 -/POC-應用/用戶/ WEB-INF /視圖/用戶.jsp

正如您所看到的，它將追加視圖「用戶」。下面是代碼，配置和pom.xml文件：

@Controller 
public class UserController { 

@RequestMapping(value = "/user", method = RequestMethod.GET) 
public String listAllUsers(Model model) { 
    model.addAttribute("users", getUsers()); 
    return "user-list"; 
} 

@RequestMapping(value = "/user/{userId}", method = RequestMethod.GET) 
public String showUserDetail(@PathVariable("userId") int userId, Model model) { 
      //not checking the list with id, this is just for test 
    UserBean bean1 = new UserBean(); 
    bean1.setBinNumber("123456"); 
    bean1.setFullName("User One"); 
    bean1.setGuid("abcdef"); 
    bean1.setShortName("User1"); 

    model.addAttribute("user",bean1); 
    return "user"; 
} 

private List<UserBean> getUsers(){ 
    List<UserBean> list = new ArrayList<UserBean>(); 

    UserBean bean1 = new UserBean(); 
    bean1.setBinNumber("123456"); 
    bean1.setFullName("User One"); 
    bean1.setGuid("abcdef"); 
    bean1.setShortName("User1"); 

    UserBean bean2 = new UserBean(); 
    bean2.setBinNumber("987654"); 
    bean2.setFullName("User Two"); 
    bean2.setGuid("xyzabc"); 
    bean2.setShortName("User2"); 

    UserBean bean3 = new UserBean(); 
    bean3.setBinNumber("555555"); 
    bean3.setFullName("User Three"); 
    bean3.setGuid("hghghg"); 
    bean3.setShortName("User3"); 

    list.add(bean1); 
    list.add(bean2); 
    list.add(bean3); 

    return list; 
} 

}

春季啓動Application.java

@ComponentScan("com.company.project")

     SpringApplication.run(VoucherAdminWebPocApplication.class, args);

注：有沒有問題，如果我定位到http://localhost:8080/app-name/user - 這工作完全正常

Answer 1

spring.view.prefix: WEB-INF/views/ 

您已經配置的前綴作爲相對URL而不是絕對URL。因此它將被添加到傳入的請求中。要解決這個問題，可以在網址的開頭添加一個/，以確保網址的絕對性。

spring.view.prefix: /WEB-INF/views/
