springcloud整合gateway实现网关的示例代码
作者：灰太狼_cxh
本文主要介绍了springcloud整合gateway实现网关的示例代码，文中通过示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
1.项目目录：
创建项目gateway作为父类
2.代码实现：
父类依赖
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.6.2</version>
<relativePath/> <!-- lookup parent from repository -->

<version>${spring-cloud-alibaba-dependencies.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
创建module项目gateway-client
添加依赖
<parent> <groupId>com.cxh</groupId> <artifactId>gateway</artifactId> <version>0.0.1-SNAPSHOT</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.cxh</groupId> <artifactId>gateway-client</artifactId> <version>0.0.1-SNAPSHOT</version> <name>gateway-client</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!--服务注册--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> <version>0.2.1.RELEASE</version> </dependency> <!--服务调用--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies>
yml配置
server: port: 8002 spring: application: name: gateway-client #服务名 profiles: active: dev #环境设置 cloud: nacos: discovery: server-addr: 127.0.0.1:8848 #nacos服务注册
控制层
@RestController
public class ClientController {
@Value("${server.port}")
private String port;
@RequestMapping("/index")
public String index(){
return "gateway-client端口：" + port;
}
}启动类添加注解
@SpringBootApplication
@EnableDiscoveryClient
public class GatewayClientApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayClientApplication.class, args);
}
}创建module项目gateway-service
添加依赖
<parent> <groupId>com.cxh</groupId> <artifactId>gateway</artifactId> <version>0.0.1-SNAPSHOT</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.cxh</groupId> <artifactId>gateway-service</artifactId> <version>0.0.1-SNAPSHOT</version> <name>gateway-service</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-gateway</artifactId> <version>3.0.4</version> </dependency> <!--服务注册/发现中心依赖--> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> </dependency> <!--服务的配置中心依赖--> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-feign</artifactId> <version>1.4.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-loadbalancer</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix</artifactId> <version>2.2.10.RELEASE</version> </dependency> </dependencies>
yml配置
server: port: 8001 spring: application: name: gateway-service #服务名 profiles: active: dev #环境设置 cloud: gateway: routes: # 透传服务 - id: gateway-client #设置路由id uri: lb://gateway-client #设置路由的url lb://nacos服务注册名称 predicates: - Path=/client/** #路径匹配规则 filters: - StripPrefix=1
跨域配置
@Configuration
public class CorsConfig {
@Bean
public CorsWebFilter corsFilter() {
CorsConfiguration config = new CorsConfiguration();
config.addAllowedMethod("*");
config.addAllowedOrigin("*");
config.addAllowedHeader("*");
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(new PathPatternParser());
source.registerCorsConfiguration("/**", config);
return new CorsWebFilter(source);
}
}3.实现效果：
启动nacos后，再启动gateway-client, gateway-service项目，打开浏览器http://localhost:8001/client/index
返回信息：gateway-client端口：8002
