I am trying to follow a tutorial and build an API Gateway for my microservices. However when I write @EnableZuulProxy above the main method, IntelliJ can't find the annotation. I have cloned a GitHub repo from this official Spring Boot tutorial and there it works. I don't know why in my other project the dependency can't be resolved. Please help!
My Main Class;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy
public class GatewayServiceApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayServiceApplication.class, args);
}
}
Their Main:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.context.annotation.Bean;
import com.example.routingandfilteringgateway.filters.pre.SimpleFilter;
@EnableZuulProxy
@SpringBootApplication
public class RoutingAndFilteringGatewayApplication {
public static void main(String[] args) {
SpringApplication.run(RoutingAndFilteringGatewayApplication.class, args);
}
@Bean
public SimpleFilter simpleFilter() {
return new SimpleFilter();
}
}
My build.gradle:
plugins {
id 'org.springframework.boot' version '2.6.1'
id 'io.spring.dependency-management' version '1.0.11.RELEASE'
id 'java'
}
group = 'xx.xxxxx'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'
repositories {
mavenCentral()
maven { url 'https://repo.spring.io/milestone' }
}
ext {

}

}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
test {
useJUnitPlatform()
}
Their build.gradle:
plugins {

id 'io.spring.dependency-management' version '1.0.10.RELEASE'
id 'java'
}
group = 'com.example'

testImplementation('org.springframework.boot:spring-boot-starter-test') {

}
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
test {
useJUnitPlatform()
}
I have tried Invalidating cache.
