        目前Spring boot可以说是Spring web最为流行的开发框架了，目前很多框架都支持Spring boot注册扫描的模式，这篇博客我们用一个示例来展示一下sofa-boot简单的开发工程。

1、创建API中相关接口及实现类

接口：

public interface IHelloService {

    public String sayHello(String name);
}

实现类：

public class HelloServiceImpl implements IHelloService {
    @Override
    public String sayHello(String name) {
        return "hello " + name;
    }
}

2、sofa boot相关pom引用

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.alipay.sofa</groupId>
                <artifactId>sofaboot-dependencies</artifactId>
                <version>2.4.5</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>
        <!-- 引入 SOFARPC 依赖 -->
        <dependency>
            <groupId>com.alipay.sofa</groupId>
            <artifactId>rpc-sofa-boot-starter</artifactId>
            <version>5.4.4</version>
        </dependency>

        <dependency>
            <groupId>com.alipay.sofa</groupId>
            <artifactId>healthcheck-sofa-boot-starter</artifactId>
            <version>2.4.5</version>
        </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>
    </dependencies>

3、sofa boot服务提供者相关配置

（1）服务发布provider.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:sofa="http://sofastack.io/schema/sofaboot"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://sofastack.io/schema/sofaboot
            http://sofastack.io/schema/sofaboot.xsd"
       default-autowire="byName">

    <bean id="helloService" class="com.tianjunwei.HelloServiceImpl"/>
    <!--对外暴露服务-->
    <sofa:service interface="com.tianjunwei.IHelloService" ref="helloService">
        <sofa:binding.bolt/>
    </sofa:service>
</beans>

（2）application.properties相关配置

# 指定应用名
spring.application.name=sofa-provider

server.port=8091
# 指定日志路径
logging.path=./logs
# 注册中心地址
com.alipay.sofa.rpc.registry.address=zookeeper://127.0.0.1:2181

（3）服务启动类

@SpringBootApplication
@ImportResource("provider.xml")
public class ProviderBootStrap {

    public static void main(String args[]){
        ApplicationContext context = SpringApplication.run(ProviderBootStrap.class,args);
    }
}

4、服务消费者相关配置（与服务提供者类似）

（1）服务引用consumer.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:sofa="http://sofastack.io/schema/sofaboot"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://sofastack.io/schema/sofaboot
            http://sofastack.io/schema/sofaboot.xsd"
       default-autowire="byName">
    <!--引用服务-->
    <sofa:reference id="helloService" interface="com.tianjunwei.IHelloService">
        <sofa:binding.bolt/>
    </sofa:reference>

</beans>

（2）application.properties中相关配置

# 指定应用名
spring.application.name=sofa-client

server.port=8090
# 指定日志路径
logging.path=./logs
# 注册中心地址
com.alipay.sofa.rpc.registry.address=zookeeper://127.0.0.1:2181

（3）服务启动类：

@SpringBootApplication
@ImportResource("consumer.xml")
public class ConsumerBootStrap {

    public static void main(String args[]){
        ApplicationContext context = SpringApplication.run(ConsumerBootStrap.class,args);
        IHelloService helloService =(IHelloService) context.getBean("helloService");
        while (true) {
            System.out.println(helloService.sayHello("sofa"));
            try{
                Thread.sleep(1000);
            }catch (Exception e){

            }

        }

    }
}
