您可以将 jsp 用于您的前端，而您的后端路由在 Spring 引导中是安静的吗？

Question

@RestController

public class IndexController {

@RequestMapping("/")
public String indexRoute() {
    return JSON HERE;
}

Suppose the above is my backend route, is there any way with jsp in which i can display that? I really dont want to use React to embed it.

Answer 1

Yes you can annotate your class with @RestController to tell Spring that it's methods will return a HTTP response body (in JSON format for example)

And you can annotate an other class with @Controller to tell Spring that it's methods will return a view name (like a JSP file name for example)

Answer 2

Controller:

@Controller
public class MyController {

    @GetMapping("/json")
    @ResponseBody
    public MyResource idexJson() {
        ...
        return res;
    }

    @GetMapping("/jsp")
    public String input(final Model model) {
        ...
        model.addAttribute(res);
        return "index";
    }

}

Additionally, you may possibly need additional configuration. For example:

properties:

spring.mvc.view.prefix= /WEB-INF/view/
spring.mvc.view.suffix= .jsp

dependencies:

    <dependency>
      <groupId>org.apache.tomcat.embed</groupId>
      <artifactId>tomcat-embed-jasper</artifactId>
    </dependency>
