Java-Chassis + CSE 搭建微服务项目

（一）搭建注册与配置中心CSE

1. 从官网下载对应版本下载地址
2. 解压文件，然后执行 cse.exe
3. 访问 http://127.0.0.1:30103 则可看到 CSE 页面

（二）项目总pom文件

1. pom.xml 文件配置

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugins>
        </pluginManagement>
    </build>
</project>

（三）服务提供者（chassis-provider）

1. pom.xml 配置

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <groupId>com.coffee</groupId>
        <artifactId>chassis-demo</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>chassis-provider</artifactId>

    <dependencies>
        <dependency>
            <groupId>org.apache.servicecomb</groupId>
            <artifactId>java-chassis-spring-boot-starter-servlet</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.1.6.RELEASE</version>
            </plugin>
        </plugins>
    </build>

</project>

2. application.yml 配置

server:
  port: 5010

servicecomb:
  service:
    application: chassis-application
    name: chassis-provider
    version: 0.0.1
    registry:
      address: http://localhost:30100
  kie:
    serverUri: http://localhost:30110

  rest:
    address: 0.0.0.0:5010

3. Controller 编写

@RestSchema(schemaId = "ProviderController")
@RequestMapping(path = "/")
public class ProviderController {

    @GetMapping("/sayHello")
    public String sayHello(@RequestParam("name") String name) {
        return "Hello " + name + ", This is Servicecomb Java Chassis + CSE!";
    }

}

4. 主启动类

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

（四）服务消费者（chassis-consumer）

1. pom.xml 配置

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <groupId>com.coffee</groupId>

        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.1.6.RELEASE</version>
            </plugin>

    </build>

</project>

2. application.yml 配置

server:
  port: 5020

servicecomb:
  service:
    application: chassis-application
    name: chassis-consumer
    version: 0.0.1
    registry:
      address: http://localhost:30100
  kie:
    serverUri: http://localhost:30110

  rest:
    address: 0.0.0.0:5020

3. Controller 编写

@RestSchema(schemaId = "ConsumerController")
@RequestMapping(path = "/")
public class ConsumerController {

    @Autowired
    private RestTemplate restTemplate;

    @GetMapping("/sayHello")
    public String sayHello(@RequestParam("name") String name) {
        return restTemplate.getForObject(
                "servicecomb://chassis-provider/sayHello?name=" + name,
                String.class);
    }

}

4. 主启动类

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

（五）网关（edge）

1. pom.xml 配置

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <groupId>com.coffee</groupId>
        <artifactId>chassis-demo</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>edge</artifactId>

    <dependencies>
        <dependency>
            <groupId>org.apache.servicecomb</groupId>
            <artifactId>java-chassis-spring-boot-starter-standalone</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.servicecomb</groupId>
            <artifactId>edge-core</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.1.6.RELEASE</version>
            </plugin>
        </plugins>
    </build>

</project>

2. application.yml 配置

server:
  port: 5000

servicecomb:
  service:
    application: chassis-application
    name: edge
    version: 0.0.1
    registry:
      address: http://localhost:30100
  kie:
    serverUri: http://localhost:30110

  rest:
    address: 0.0.0.0:5000

  http:
    dispatcher:
      edge:
        default:
          enabled: false
        url:
          enabled: true
          pattern: /(.*)
          mappings:
            consumer:
              prefixSegmentCount: 0
              path: "/.*"
              microserviceName: chassis-consumer
              versionRule: 0.0.0+

3. 主启动类

@SpringBootApplication
@EnableServiceComb
public class EdgeApplication {
  public static void main(String[] args) {
    new SpringApplicationBuilder().web(WebApplicationType.NONE).sources(EdgeApplication.class).run(args);
  }
}

（六）验证

1. 分别启动chassis-provider、chassis-consumer 和 edge
2. 访问 http://localhost:5000/sayHello?name=chassis，返回 “Hello chassis, This is Spring Cloud Eureka!” 则项目搭建成功。
