4.controller
@RestController @Slf4j public class OrderController { public static final String PAYMENT_URL = "http://localhost:8001"; @Resource private RestTemplate restTemplate; @GetMapping("/consumer/payment/create")客户端用浏览器是get请求，但是底层实质发送post调用服务端8001 public CommonResult<Payment> create(Payment payment){ return restTemplate.postForObject(PAYMENT_URL+"/payment/create",payment,CommonResult.class); } @GetMapping("/consumer/payment/get/{id}") public CommonResult<Payment> getPayment(@PathVariable("id") Long id){ return restTemplate.getForObject(PAYMENT_URL+"/payment/get/"+id,CommonResult.class); } }
测试
备注:
使用postman或者rest client测试报出Required request body is missing 错误(而在其他场合发送post请求时根据需要进行添加该注解.)
解决：把 @RequestBody去掉
1.2.4 工程重构
观察问题
系统中有重复部分，所以应该重构
新建 cloud-api-commons
改POM
<?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>cloud2021</artifactId> <groupId>com.rg.springcloud</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>cloud-api-commons</artifactId> <dependencies> <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> <dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>5.1.0</version> </dependency> </dependencies> </project>
- pojo
添加Payment实体和CommonResult通用封装类
- maven命令clean install
- 订单80和支付8001分别改造
删除各自的原先有过的entities文件夹==>各自粘贴POM内容
<!-- 引入自己定义的api通用包，可以使用Payment支付Entity --> <dependency> <groupId>com.rg.springcloud</groupId> <artifactId>cloud-api-commons</artifactId> <version>${project.version}</version> </dependency>
