Spring MVC controller cannot take effect

[xiaohanfeidao]

Hey,

I integrated grizzly starter in my project，The codes are as follows:

org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-tomcat

    <dependency>
        <groupId>be.dabla</groupId>
        <artifactId>grizzly-spring-boot-starter</artifactId>
        <version>2.7</version>
    </dependency>

@SpringBootApplication public class App { public static void main( String[] args ) { SpringApplication.run(App.class, args); }

@Bean
public ResourceConfigCustomizer resourceConfigCustomizer() {
    return new ResourceConfigCustomizer() {
        @Override
        public void customize(ResourceConfig resourceConfig) {
            Map<String,Object> properties = new HashMap<>();
            properties.put("com.sun.jersey.api.json.POJOMappingFeature", "true");
            properties.put("com.sun.jersey.config.feature.trace", "ALL");
            resourceConfig.addProperties(properties);
        }
    };
}

}

spring mvc controller file： import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping;

/**

• @author sheng

• @date 2022/6/23 13:08 */ @RequestMapping public class TestController {

  @GetMapping("/hello") public String message() { return "Hello World"; } }

application.yml: spring: application: name: app-grizzly jersey: application-path: /jersy

server: port: 8082 servlet: context-path: /

The startup log is as follows:

Access error：

Hello, I see you have defined following in YAML file:

jersey: application-path: /jersy

This is also shown in you logging above:

2022-06-23 14:33:31.162 INFO 24620 --- [ main] o.g.grizzly.servlet.WebappContext : [application] Servlet [org.glassfish.jersey.servlet.ServletContainer] registered for url pattern(s) [[/jersy/]].

So try following path: http://localhost:8082/jersy/hello

Also if you want to use the Spring REST controllers instead of Jersey (which is the default for Grizzly), then you need to specify following parameter in your YAML file as stated in the README.md, see the section concerning it.

spring.jersey.application-path=/api

Hey，In this way, the access also returns error

According to the wiki guidelines, I only need to distinguish the root path of spring MVC and Jersy, You can see that I have distinguished the root path between spring MVC and Jersey。

I still can't find the wrong configuration，hope to get your help，thanks。

That's the issue, as already stated:

Since version 2.6 it is possible to use the Spring REST controllers instead of the default Jersey JAX-RS implementation. To be able to do so, make sure you specify the spring.jersey.application-path property to a specific path which is different than the root (e.g. /) otherwise there will be a path conflict and requests will never be able to reach the Spring DispatcherServlet.

Try setting it to /api as I said before and see if that works, it won't work when registered to the root due to the fact how Grizzly internal works.
