不支持请求方法 'POST'。 Spring+百里香叶

Question

**大家好。我运行在开发 Web 应用程序时遇到了问题。 saveEmployee 方法无法正常工作并抛出相应的错误。在项目中我使用 Spring-boot + Thymeleaf。我认为这两个文件有错误或者配置有问题。但到目前为止我还没有发现任何东西。 **

myRestController.java

    @Controller
@RequestMapping("/shop")
public class myRestController {

    @Autowired
    private EmployeeService employeeService;


    @GetMapping("/allEmployees")
    public String allEmployees(Model model) {
        List<Employee> employees = employeeService.getAllEmployees();
        model.addAttribute("employeesList", employees);
        return "allEmployees";
    }

    @GetMapping("/allEmployees/{name}")
    public String getEmployeeByName(@PathVariable String name, Model model) {
        List<Employee> employees = employeeService.findAllByName(name);
        model.addAttribute("employeesList", employees);
        return "allEmployees";
    }

    @GetMapping("/newEmployee")
    public String addEmployee(Model model) {
        Employee employee = new Employee();
        model.addAttribute("employee", employee);
        return "addNewEmployee";
    }

    @RequestMapping()
    public String saveEmployee(@ModelAttribute("employee") Employee employee){
        employeeService.saveEmployee(employee);
        return "index";
    }

addNewEmployee.html

 <!DOCTYPE html>

在您的 myRestController.java 中，我没有看到任何 @PostMapping 定义。在 addNewEmployee.html 中，您似乎正试图使用 POST 而不是 GET 方法调用 shop/allEmployees。如果您打算将正文或表单传递到 shop/allEmployees 端点，您可能需要考虑将 @GetMapping 更改为接受 @RequestBody 的 @PostMapping 或创建一个接受 @RequestBody.

的全新 @PostMapping
