SpringCloud创建服务提供者与消费者

相关依赖

提供者：

 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.3</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.22</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <dependency> <groupId>com.hht.cloud</groupId> <artifactId>cloud-api-commons</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> 

消费者：

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> 

支付业务代码（提供者）

结构如下：

yml配置：

spring: application: name: cloud-payment-service datasource: driver-class-name: com.mysql.cj.jdbc.Driver username: root password: 123456 url: jdbc:mysql://localhost:3306/cloutstudy #指定数据源为druid type: com.alibaba.druid.pool.DruidDataSource devtools: restart: #增加热部署检测时间，防止出现404 poll-interval: 3s mybatis: mapper-locations: classpath:mapper/*.xml server: port: 8011 

主要业务服务代码：

创建和查询操作：

@Service public class PaymentServiceImpl implements PaymentService { @Resource PaymentMapper paymentMapper; @Override public int create(Payment payment) { return paymentMapper.create(payment); } @Override public Payment getPaymentById(Long id) { return paymentMapper.getPaymentById(id); } } 

订单业务代码（消费者）

结构如下：

目前还没有使用注册中心来注册服务，所以先使用restTemplate来进行远程调用提供者的业务服务

容器配置类：

@Configuration public class ApplicationContextConfig { //注册restTemplate进容器 @Bean public RestTemplate getRestTemplate(){ return new RestTemplate(); } } 

控制器如下：

@RestController @Slf4j @RequestMapping("/consumer/payment") public class OrderController { public static final String PAYMENT_URL="http://localhost:8011"; @Autowired private RestTemplate restTemplate; @PostMapping("/create") public CommonResult<Payment> create(Payment payment){ return restTemplate.postForObject(PAYMENT_URL+"/payment/create",payment,CommonResult.class); } @GetMapping("/get/{id}") public CommonResult<Payment> getPayment(@PathVariable Long id){ return restTemplate.getForObject(PAYMENT_URL+"/payment/get/"+id,CommonResult.class); } }
