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>
            
            <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"/>
        
        <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">
        
        <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){
    
                }
    
            }
    
        }
    }
