1，创建maven项目工程如下

• equipment-admin 后台
• equipment-applet 前台或小程序端或app、h5
• equipment-common 公共模块
• equipment-gateway 网关
• equipment-mapper mapper层操作数据库
• equipment-model 实体类对应数据库表

2，在父pom文件引入依赖

  <properties>
    <project.build.sourceEncoding>UTF‐8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF‐8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <spring.cloud.alibaba.version>2.2.6.RELEASE</spring.cloud.alibaba.version>
    <spring.boot.version>2.3.2.RELEASE</spring.boot.version>
    <spring.cloud.version>Hoxton.SR9</spring.cloud.version>
  </properties>


  <dependencyManagement>
    <dependencies>
      <!--Spring Cloud Alibaba 版本管理器-->
      <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-alibaba-dependencies</artifactId>
        <version>${spring.cloud.alibaba.version}</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
      <!--Spring Boot 版本管理器-->
      <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-dependencies</artifactId>
        <version>${spring.boot.version}</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
      <!--Spring Cloud 版本管理器-->
      <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-dependencies</artifactId>
        <version>${spring.cloud.version}</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>

3，在admin和applet中引入依赖

<dependencies>
        <dependency>
            <groupId>awz.equipment</groupId>
            <artifactId>equipment-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.3.0.RELEASE</version>
                <configuration>
                    <mainClass>awz.equipment.getway.EquipmentGatewayMain</mainClass>
                    <layout>ZIP</layout>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <!-- 将依赖到的包都放进去 -->
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>8</source>
                    <target>8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

4，在gateway网关引入依赖

 <dependencies>
        <!-- 引入gateway网关 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-web</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.3.0.RELEASE</version>
                <configuration>
                    <mainClass>awz.equipment.getway.EquipmentGatewayMain</mainClass>
                    <layout>ZIP</layout>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <!-- 将依赖到的包都放进去 -->
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>8</source>
                    <target>8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

5，编写启动类

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

admin和applet依次编写

6，分别在admin和applet中编写测试接口

@GetMapping(value = "/test")
    public R test() {
        return new R(ResultEnum.SUCCESS);
    }

7，网关编写断言

server:
  port: 9090

spring:
  application:
    name: equipment-gateway
  cloud:
    gateway:
      routes:
        - id: equipment-admin
#          uri: lb://equipment-admin
          uri: http://localhost:9091
          predicates:
            - Path=/admin/**
#          filters:
#            - AddResponseHeader=X-Response-Foo, Bar
#            # AuthorizeGatewayFilterFactory自定义过滤器配置，值为true需要验证授权，false不需要
#            - Authorize=true

        - id: equipment-applet
#          uri: lb://equipment-applet
          uri: http://localhost:9092
          predicates:
            - Path=/applet/**

启动测试，访问网关接口即可完成转发
