SpringBoot中带有@PathVariable的方法返回空响应

Question

我试图编写一个方法，它接受@PathVariable参数，并将用户重定向到一个jsp文件。

@Controller
public class MainController 
{

    @RequestMapping("/user/{customerId}")
    // http://localhost:8080/Test/user/5
    public String getCustomerById(@PathVariable("customerId") String customerId, Model model) 
    {
            model.addAttribute("customer_id", customerId);
            // this is the user_details.jsp file, I need to show this jsp file to visitor
            return "user_details";
    }
}

@pathvariable(value=“customerId”）字符串customerId

@pathvariable(name=“customerId”）字符串customerId

@pathvariable（“customerId”）字符串customerId

@RestController
public class RestApi
{
    // http://localhost:8080/Test/api/user/56
    // Is Working, Returns Hello 56 As Response
    @RequestMapping("api/user/{customerId}")
    public String apiTest(@PathVariable("customerId") String customerId)
    {
        return "Hello "+customerId; 
    }
}

请检查您的application.properties文件...

前缀和后缀

spring.mvc.view.prefix: (Where are jsp files) Example /WEB-INF/ or / 
spring.mvc.view.suffix: .jsp
