-Dubbo和Java chassis底层都使用了Spring的依赖注入和bean管理系统，所以使用Dubbo的服务迁移到ServiceComb工作量较小，
-主要改动在依赖和配置方面。
-
-本文示例代码可在[Java chassis](https://github.com/ServiceComb/ServiceComb-Java-Chassis/tree/master/samples)中获取。
-
-## 服务提供方
-### 替换依赖
-将对dubbo的依赖替换为对Java chassis的依赖
-
-Dubbo
-```xml
- <dependency>
- <groupId>com.alibaba</groupId>
- <artifactId>dubbo</artifactId>
- <version>${dubbo.version}</version>
- </dependency>
-```
-
-Java chassis
-```xml
- <dependencyManagement>
- <dependencies>
- <dependency>
- <groupId>io.servicecomb</groupId>
- <artifactId>java-chassis-dependencies</artifactId>
- <version>${java.chassis.version}</version>
- <type>pom</type>
- <scope>import</scope>
- </dependency>
- </dependencies>
- </dependencyManagement>
-
- <dependencies>
- <dependency>
- <groupId>io.servicecomb</groupId>
- <artifactId>transport-highway</artifactId>
- </dependency>
- <dependency>
- <groupId>io.servicecomb</groupId>
- <artifactId>transport-rest-vertx</artifactId>
- </dependency>
- <dependency>
- <groupId>io.servicecomb</groupId>
- <artifactId>provider-pojo</artifactId>
- </dependency>
- </dependencies>
-```
-
-### 替换服务接口注释
-以 `@Service` 注释方式暴露的服务接口，用 `@RpcSchema` 替代
-
-Dubbo
-```java
-import com.alibaba.dubbo.config.annotation.Service;
-
-@Service
-public class SomeServiceImpl implements SomeService {
- // ...
-}
-```
-
-Java chassis
-```java
-@RpcSchema(schemaId = "someServiceEndpoint")
-public class SomeServiceImpl implements SomeService {
- // ...
-}
-```
-
-### 修改提供方启动入口
-
-Dubbo
-```java
-public class ProviderMain
-{
-
- public static void main(String[] args) throws Exception
- {
- @SuppressWarnings(
- { "resource", "unused" })
- ApplicationContext context = new ClassPathXmlApplicationContext("conf/applicationContext.xml");
- System.out.println("Dubbo provider started successfully...");
-
- System.in.read();
- }
-}
-```
-
-Java chassis
-```java
-public class ProviderMain
-{
-
- public static void main(String[] args) throws Exception
- {
- Log4jUtils.init();
- BeanUtils.init();
-
- System.out.println("ServiceComb provider started successfully...");
- }
-}
-```
-
-### 修改服务提供方配置
-Dubbo服务通过一个XML文件同时配置了服务接口、服务注册中心地址、服务监听端口等所有内容。
-```xml
-<?xml version="1.0" encoding="UTF-8"?>
-
-<beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
- xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
- http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
-
- <dubbo:application name="provider-service" />
-
- <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" />
-
- <dubbo:protocol name="dubbo" port="20880" />
-
- <dubbo:annotation package="io.servicecomb.demo" />
-
- <!-- 以XML配置方式暴露的服务 -->
- <dubbo:service interface="io.servicecomb.demo.api.AnotherService" ref="anotherServiceImpl" />
- <bean id="anotherServiceImpl" class="io.servicecomb.demo.provider.AnotherServiceImpl" />
-
-</beans>
-```
-
-Java chassis也同样提供了以XML文件暴露服务接口的方式，但其他服务配置则通过 `microservice.yaml` 文件提供。
-```xml
-<?xml version="1.0" encoding="UTF-8"?>
-<beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

- xmlns:context="http://www.springframework.org/schema/context"
- xsi:schemaLocation="

- http://www.huawei.com/schema/paas/cse/rpc classpath:META-INF/spring/spring-paas-cse-rpc.xsd">
-
- <!-- 以XML配置方式暴露的服务 -->
- <cse:rpc-schema schema-id="anotherServiceEndpoint" implementation="io.servicecomb.demo.provider.AnotherServiceImpl"/>
-</beans>
-```
-
-```yaml
-APPLICATION_ID: my-application
-service_description:
- name: service-provider

-cse:
- service:
- registry:
- address: http://127.0.0.1:30100 # 服务注册中心地址
- rest:
- address: 0.0.0.0:8080 # 服务REST端口
-```
-
-## 服务消费方
-### 替换依赖
-将对Dubbo的依赖替换为对Java chassis的依赖
-
-Dubbo
-```xml
- <dependency>
- <groupId>com.alibaba</groupId>
- <artifactId>dubbo</artifactId>
- <version>${dubbo.version}</version>
- </dependency>
-```
-
-Java chassis
-```xml

- <groupId>io.servicecomb</groupId>
- <artifactId>java-chassis-dependencies</artifactId>
- <version>${java.chassis.version}</version>

- </dependency>
- </dependencies>
-```
-
-### 修改消费方启动入口
-Dubbo
-```java
-public class ConsumerMain
-{
-
- public static void main(String[] args) throws Exception
- {
- @SuppressWarnings(
- { "resource", "unused" })
- ApplicationContext context = new ClassPathXmlApplicationContext("conf/applicationContext.xml");
- System.out.println("Dubbo Consumer started successfully...");
-
- System.in.read();
- }
-}
-```
-
-Java chassis
-```java
-public class ConsumerMain
-{
-
- public static void main(String[] args) throws Exception
- {
- Log4jUtils.init();
- BeanUtils.init();
-
- System.out.println("ServiceComb Consumer started successfully...");
- }
-}
-```
-
-### 服务异步调用
-Dubbo
-```java
- SomeService someService = (SomeService) context.getBean("someServiceRef");
- String hello = someService.sayHello("world");
- Future<String> future = RpcContext.getContext().getFuture();
- return future.get();
-```
-
-Java chassis
-```java
- ApplicationContext context = BeanUtils.getContext();
- SomeService someService = (SomeService) context.getBean("someServiceRef");
-
- CompletableFuture<String> future = CompletableFuture.supplyAsync(() -> someService.sayHello("world"));
- return future.get();
-```
-
-### 修改服务提供方配置
-Dubbo服务通过一个XML文件同时配置了远程服务提供方接口、服务注册中心地址、服务监听端口等所有内容。
-```xml
-<?xml version="1.0" encoding="UTF-8"?>
-<beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
- xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
- http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
-
- <dubbo:application name="consumer-service" />
-
- <dubbo:protocol name="dubbo" port="20880"/>
- <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" />
-
- <dubbo:reference id="someServiceRef"
- interface="io.servicecomb.demo.api.SomeService"
- async="true" timeout="30000" />
-
- <dubbo:reference id="anotherServiceRef"
- interface="io.servicecomb.demo.api.AnotherService"
- async="true" timeout="30000" />
-</beans>
-```
-
-Java chassis也同样提供了以XML文件引用远程服务提供方接口的方式，但其他服务配置则通过 `microservice.yaml` 文件提供。
-```xml
-<?xml version="1.0" encoding="UTF-8"?>
-<beans xmlns="http://www.springframework.org/schema/beans"
