Question

如果执行的URL包含相应Controller的@RequestMapping中提到的单词，是否可以调用Controller？

这是我的代码

@Controller
@RequestMapping({"/employee","/nonemployee","/temp"})
public class EmployeeController {

   @Autowired
   EmployeeService service;

   @RequestMapping("/add")
   public ModelAndView employee() {
      ModelAndView modelAndView = new ModelAndView("emp/add", "command", new Employee());
      return modelAndView;
   }

   @RequestMapping("/employees")
   public ModelAndView getEmployeeList() {
      ModelAndView modelAndView = new ModelAndView("/emp/employees", "list", service.getEmployeeList());
      return modelAndView;
   }

   @RequestMapping(value = "/create")
   public String createEmployee(@ModelAttribute Employee employee, ModelMap model) {
      service.newEmployee(employee);
      model.addAttribute("name", employee.getName());
      model.addAttribute("age", employee.getAge());
      model.addAttribute("id", employee.getId());
      return "/emp/create";
   }
}

将以上代码与@RequestMapping({"/employee","/nonemployee","/temp"})和@RequestMapping("/employees")一起使用，我们可以调用以下网址来列出值：

http://localhost:8080/Spring/employee/employees
http://localhost:8080/Spring/nonemployee/employees
http://localhost:8080/Spring/temp/employees

仔细观察，我们可以在传递给RequestMapping的所有三个单词/值中看到匹配的单词 emp 。所以，我正在寻找的是用于执行Controller的方式，如果URL包含单词 emp 。

执行以下URL时，必须使用相同的方法（getEmployeeList()）返回值列表，但不要将多个或所有值传递给RequestMapping Annotation：

http://localhost:8080/Spring/employee/employees
http://localhost:8080/Spring/nonemployee/employees
http://localhost:8080/Spring/temp/employees
http://localhost:8080/Spring/exempt/employees
http://localhost:8080/Spring/attempt/employees

将请求映射更改为 -

               @RequestMapping("/*emp*")

这应该适用于您想要做的事情。

Spring MVC，如果RequestMapping中提到的单词在URL中匹配，则调用Controller
