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-jasper
和jstl
在pom.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
的pom.xml:

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。 –
