三，创建订单微服务消费者 第三章

 

 4.3 修改pom添加依赖

 <dependencies><!--web--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!--监控--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><!--热部署--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><scope>runtime</scope><optional>true</optional></dependency><!--lombok--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><!--测试--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId></dependency></dependencies>

 4.4编写yml文件

server:port: 80spring:application:name:springcloud-consumer-order-service

4.5编写启动类

@SpringBootApplication
public class OrderApplication {public static void main(String[] args) {SpringApplication.run(OrderApplication.class,args);}
}

4.6建立实体

package cn.bdqn.domain;import java.io.Serializable;public class Payment implements Serializable {private Integer id;private String  flowNumber;public void setId(Integer id) {this.id = id;}public void setFlowNumber(String flowNumber) {this.flowNumber = flowNumber;}public Integer getId() {return id;}public String getFlowNumber() {return flowNumber;}
}

4.7编写响应结果的Bean

package cn.bdqn.bean;public class ResponseResult <T> {//响应的编码private Integer code;//响应给前段用户的消息提示private String message;//响应的数据private T data;public ResponseResult() {}public ResponseResult(Integer code, String message, T data) {this.code = code;this.message = message;this.data = data;}public Integer getCode() {return code;}public String getMessage() {return message;}public T getData() {return data;}public void setCode(Integer code) {this.code = code;}public void setMessage(String message) {this.message = message;}public void setData(T data) {this.data = data;}
}

 

 

 4.8 RestTemplate注册到spring

@Configuration
public class ApplicationContextConfig {@Beanpublic RestTemplate restTemplate(){return new RestTemplate();}
}

4.9编写OrderApplication控制器

public class OrderController {private static final String PAYMENT_URL="http://localhost:8001";@Autowiredprivate RestTemplate restTemplate;//根据id查询@GetMapping("/consumer/payment/get/{id}")public ResponseResult queryById(@PathVariable("id") Integer id){ResponseResult rs =restTemplate.getForObject(PAYMENT_URL+"/payment/id"+id,ResponseResult.class);return rs;}//创建订单@GetMapping("/consumer/payment/save")public ResponseResult save(Payment payment){ResponseResult rs =restTemplate.postForObject(PAYMENT_URL+"/payment/save", payment,ResponseResult.class);return  rs;}

1. 4.11问题

2. 
3. 因为

 支付提供者端的代码如下

  @PostMapping("/payment/save")public ResponseResult save(@RequestBody Payment payment){try {paymentService.save(payment);return new ResponseResult(200,"成功",null);}catch (Exception e){e.printStackTrace();return new ResponseResult(500,"失败",null);}}
