2.1 技术选型

2.2 模块设计

2.3 微服务调用

2.4 创建⽗⼯程

2.5 创建商品微服务

2.6 创建订单微服务

 

2.1 技术选型

持久层: SpingData Jpa
数据库: MySQL5.7
其他: SpringCloud Alibaba 技术栈

2.2 模块设计

--- shop-parent ⽗⼯程
--- shop-product-api 商品微服务api 【存放商品实体】
--- shop-product-server 商品微服务 【端⼝:8081】
--- shop-order-api 订单微服务api 【存放订单实体】
--- shop-order-server 订单微服务 【端⼝:8091】

2.3 微服务调用

在微服务架构中，最常⻅的场景就是微服务之间的相互调⽤。我们以电商系统中常⻅的⽤户下单为
例来演示微服务的调⽤：客户向订单微服务发起⼀个下单的请求，在进⾏保存订单之前需要调⽤商品微服务查询商品的信息。
我们⼀般把服务的主动调⽤⽅称为服务消费者，把服务的被调⽤⽅称为服务提供者。

 

2.4 创建⽗⼯程

        创建⼀个maven⼯程，然后在pom.xml⽂件中添加下⾯内容 
<?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"><modelVersion>4.0.0</modelVersion><groupId>cn.wolfcode</groupId><artifactId>shop-parent</artifactId><version>1.0.0</version><packaging>pom</packaging><!--⽗⼯程--><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.2.RELEASE</version></parent><!--依赖版本的锁定--><properties><java.version>1.8</java.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><spring-cloud.version>Hoxton.SR8</spring-cloud.version><spring-cloud-alibaba.version>2.2.3.RELEASE</spring-cloudalibaba.version></properties><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>${spring-cloud-alibaba.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement>
</project>

2.5 创建商品微服务

        1.创建shop-product-api项⽬，然后在pom.xml⽂件中添加下⾯内容 
<?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><artifactId>shop-parent</artifactId><groupId>cn.wolfcode</groupId><version>1.0.0</version></parent><modelVersion>4.0.0</modelVersion><artifactId>shop-product-api</artifactId><!--依赖--><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-jpa</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency></dependencies>
</project>
2 创建实体类 
//商品
@Entity(name = "t_shop_product")
@Data
public class Product {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long pid;//主键private String pname;//商品名称private Double pprice;//商品价格private Integer stock;//库存
}
3.创建shop-product-server项⽬，然后在pom.xml⽂件中添加下⾯内容
<?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><artifactId>shop-parent</artifactId><groupId>cn.wolfcode</groupId><version>1.0.0</version></parent><modelVersion>4.0.0</modelVersion><artifactId>shop-product-server</artifactId><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.56</version></dependency><dependency><groupId>cn.wolfcode</groupId><artifactId>shop-product-api</artifactId><version>1.0.0</version></dependency></dependencies>
</project>
4.编写启动类ProductServer.java

@SpringBootApplication
public class ProductServer {public static void main(String[] args) {SpringApplication.run(ProductServer.class,args);}
}
5.编写配置⽂件application.yml
server:
        port: 8081
spring:
        application:
                name: product-service
        datasource:
                driver-class-name: com.mysql.jdbc.Driver
                url: jdbc:mysql:///shop-product?
serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=true
                username: root
                password: admin
        jpa:
                properties:
                        hibernate:
                                hbm2ddl:
                                        auto: update
                                        dialect: org.hibernate.dialect.MySQL5InnoDBDialect
6.在数据库中创建shop-product的数据库

7.创建ProductDao 
public interface ProductDao extends JpaRepository<Product, Long> {
}
8.创建ProductService接⼝和实现类 
@Service
public class ProductServiceImpl implements ProductService {@Autowiredprivate ProductDao productDao;@Overridepublic Product findByPid(Long pid) {return productDao.findById(pid).get();}
}
9.创建Controller
@RestController
@Slf4j
public class ProductController {@Autowiredprivate ProductService productService;//商品信息查询@RequestMapping("/product/{pid}")public Product findByPid(@PathVariable("pid") Long pid) {log.info("接下来要进⾏{}号商品信息的查询", pid);Product product = productService.findByPid(pid);log.info("商品信息查询成功,内容为{}", JSON.toJSONString(product));return product;}
}
10.启动⼯程，等到数据库表创建完毕之后，加⼊测试数据
INSERT INTO t_shop_product VALUE(NULL,'⼩⽶','1000','5000');
INSERT INTO t_shop_product VALUE(NULL,'华为','2000','5000');
INSERT INTO t_shop_product VALUE(NULL,'苹果','3000','5000');

}
5.编写配置⽂件application.yml
server:
        port: 8091
spring:
        application:
                name:order-service
        datasource:
                driver-class-name: com.mysql.jdbc.Driver
                url: jdbc:mysql:///shop-order? serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=true
                username: root
                password: admin
        jpa:
                properties:
                        hibernate:
                                hbm2ddl:
                                        auto: update
                                        dialect: org.hibernate.dialect.MySQL5InnoDBDialect

productId);//远程调⽤商品微服务,查询商品信息Product product = null;log.info("查询到{}号商品的信息,内容是:{}", productId,
JSON.toJSONString(product));//创建订单并保存Order order = new Order();order.setUid(userId);order.setUsername("叩丁狼教育");order.setPid(productId);order.setPname(product.getPname());order.setPprice(product.getPprice());order.setNumber(1);orderDao.save(order);log.info("创建订单成功,订单信息为{}", JSON.toJSONString(order));return order;}
}
9.创建Controller
@RestController
@Slf4j
public class OrderController {@Autowiredprivate OrderService orderService;@RequestMapping("/save")public Order order(Long pid,Long uid) {return orderService.createOrder(pid,uid);}
}

10.直接往数据库中添加几条数据，启动项目进行调用即可。
