我正在開發簡單的Spring Boot MVC應用程序。以前我只使用了Spring + Hibernate(也就是servlet.xml等),我試圖重建項目以使用Spring Boot。雖然我已閱讀了很多答案,但我仍然無法修復Spring Boot找不到我的.jsp文件 - 它顯示白標籤錯誤頁面。
關於SO的很多答案都包括tomcat-embed-jasperjstlpom.xml但我已經擁有它。我正在使用IntelliJ IDEA 17 Ultimate,Tomcat 8.5.13,最新版本的Spring和Spring Boot。Spring Boot jsp文件無法找到

    <div> 
 
     <div> 
 
      <!-- put new button: Add Customer -->

      <table>

而且它的控制器

@Controller 
@RequestMapping("/customers") 
public class CustomersController implements IUtilities<Customer> 
{ 
    @Autowired 
    private ICustomerDAO customerDAO; 

    @GetMapping("/manageCustomers") 
    public String manageCustomers(Model model) 
    { 
     List<Customer> allCustomers = convertIterableToCollection(customerDAO.findAll()); 
     model.addAttribute("allCustomers", allCustomers); 
     return "manage-customers"; 
    } 

    @GetMapping("/addCustomer") 
    public String showFormForAdd(Model model) 
    { 
     // create model attribute to bind form data 
     Customer theCustomer = new Customer(); 

     model.addAttribute("customerToEdit", theCustomer); 

     return "customer-form"; 
    } 

    @GetMapping("/updateCustomer") 
    public String showFormForUpdate(@RequestParam("customerID") int customerId, Model model) 
    { 
     // get the customer from service 
     Customer theCustomer = customerDAO.findOne(customerId); 
     model.addAttribute("customerToEdit", theCustomer); 

     //redirect to update form 
     return "customer-form"; 
    } 

    @GetMapping("/deleteCustomer") 
    public String deleteCustomer(@RequestParam("customerID") int customerId) 
    { 
     //delete the customer 
     customerDAO.delete(customerId); 

     return "redirect:/customers/manageCustomers"; 
    } 

    @PostMapping("/saveCustomer") 
    public String saveCustomer(@ModelAttribute("customerToEdit") Customer customer) { 
     //save the customer using our service 
     customerDAO.save(customer); 

     return "redirect:/customers/manageCustomers"; 
    } 

    @Override 
    public List<Customer> convertIterableToCollection(Iterable<Customer> iterable) { 
     List<Customer> list = new ArrayList<>(); 
     iterable.forEach(list::add); 
     return list; 
    } 
}

你在哪裏添加bean viewResolver –

我想我沒有什麼像viewResolver在我的項目中,我既沒有XML文件也沒有任何配置類 – Colonder

看到我的答案,你的基本問題是不使用預期的Maven項目佈局。 –

您使用Spring啓動,但你的POM是充滿了矛盾的依賴。初學者可以清理你的pom.xml。另外,在你的POM中,你應該考慮什麼是在JSP Samples pom.xml正在做(這意味着至少使spring-boot-starter-tomcatprovided,而不是默認compile範圍。

最後,你不需要maven-compilemaven-war的插件,這些都是已經繼承自父。

還要考慮到the limitations有使用Spring啓動時使用JSP。

但是實際的問題是,你的項目結構,你是全光照g Maven應該有一個src/main/java目錄用於你的java源代碼,並且你所有的網絡相關的東西都應該在src/main/webapp而不是web之內,非java相關的資源應該在src/main/resources。由於沒有這個默認的結構文件不會被複制到正確的位置(實際上它們將被忽略)。

我繼承了以前版本的項目中的'pom.xml' - 我會嘗試清理它並查看它是否正常工作 – Colonder

請參閱我的修改答案(實際問題是您的項目結構)。不少的清理你的pom將防止進一步的問題(和維護)。 –

這就是我認爲的誠實,但仍然是IntelliJ在創建新項目時給我的東西。這是否意味着我在使用Spring Boot和Maven時每次都必須手動重建項目結構? – Colonder
