支付微服务配置

1，建module

2，改pom

3，写yml

4，主启动

5，业务类

新建一个父级项目

2，YML文件

server:
  port: 7001

spring:
  application:
    name: cloud-eureka-server

    service-url:
      defaultZone: http://eureka7002.com:7002/eureka
  instance:
    hostname: eureka7001.com

3，主启动类

@SpringBootApplication

public class EurekaServer7001Main {
    public static void main(String[] args) {
        SpringApplication.run(EurekaServer7001Main.class,args);
    }
}

Eureka注册中心模块7002，与7001相互注册，相互守望。pom文件一致，yml和住启动类略微区别

1，YML文件

    lease-expiration-duration-in-seconds: 90



mybatis:
  mapper-locations: classpath*:mapper/*.xml
  type-aliases-package: com.company.pojo

3，主启动类

@SpringBootApplication
@EnableEurekaClient
public class Payment8001Main {
    public static void main(String[] args) {
        SpringApplication.run(Payment8001Main.class,args);
    }
}

4，mapper接口及Mapper.xml文件

@Mapper
public interface PaymentMapper {
    int savePayment(Payment payment);
    Payment getPaymentById(Integer id);
}
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.company.mapper.PaymentMapper">
    <insert id="savePayment" parameterType="payment" useGeneratedKeys="true" keyProperty="id" keyColumn="id">
        insert into payment(serial) values(#{serial})
    </insert>
    <select id="getPaymentById" parameterType="Integer" resultType="payment">
        select * from payment where id=#{id}
    </select>
</mapper>

5，service接口以及实现

public interface PaymentService {
    int savePayment(Payment payment);
    Payment getPaymentById(Integer id);
}
@Service
public class PaymentServiceImpl implements PaymentService {

    @Autowired
    private PaymentMapper paymentMapper;

    @Override
    public int savePayment(Payment payment) {
        return paymentMapper.savePayment(payment);
    }

    @Override
    public Payment getPaymentById(Integer id) {
        return paymentMapper.getPaymentById(id);
    }
}

6，controller层

@RestController
public class PaymentController {
    @Autowired
    private PaymentService paymentService;

    @Value("${server.port}")
    private String serverPort;

    @GetMapping("/payment/{id}")
    @ResponseBody
    public CommonRestult getPayment(@PathVariable("id") Integer id){
        Payment payment = paymentService.getPaymentById(id);
        if(payment!=null){
            return new CommonRestult(200,"成功获取 port:"+serverPort,payment);
        }else{
            return new CommonRestult(404,"获取失败 port:"+serverPort+" id:"+id);
        }
    }

    @PostMapping("/payment")
    @ResponseBody
    public CommonRestult savePayment(@RequestBody Payment payment){
        int i = paymentService.savePayment(payment);
        if(i>0){
            return new CommonRestult(200,"保存成功 port:"+serverPort,payment);
        }else{
            return new CommonRestult(404,"保存失败 port:"+serverPort);
        }
    }
}

支付模块8002与8001模块基本一样

订单模块81

1，POM文件

2，YML文件

server:
  port: 81
spring:
  application:

  client:
    fetch-registry: true
    register-with-eureka: true

    lease-renewal-interval-in-seconds: 30
    lease-expiration-duration-in-seconds: 90
    prefer-ip-address: true

3，主启动类

@SpringBootApplication
@EnableEurekaClient
public class Order81Main {
    public static void main(String[] args) {
        SpringApplication.run(Order80Main.class,args);
    }
}

4，配置文件

@Configuration
public class MyConfig {

    @Bean
    @LoadBalanced
    public RestTemplate restTemplate(){
        return new RestTemplate();
    }
}

5，控制层

@RestController
public class OrderController {
    private final String URL="http://CLOUD-PAYMENT-SERVICE";

    @Autowired
    private RestTemplate restTemplate;

    @PostMapping("/consumer/payment")
    @ResponseBody
    public CommonRestult savePayment(@RequestBody Payment payment){
        CommonRestult commonRestult = restTemplate.postForObject(URL+"/payment", payment, CommonRestult.class);
        return commonRestult;
    }

    @GetMapping("/consumer/payment/{id}")
    @ResponseBody
    public CommonRestult getPaymentById(@PathVariable("id") Integer id){
        CommonRestult commonRestult = restTemplate.getForObject(URL + "/payment/" + id, CommonRestult.class);
        return commonRestult;
    }


}

RestTemplate提供多种便捷访问远程http服务的方法，是一种简单便捷的访问restful服务模板类，是Spring提供的用于Rest服务的客户端模板工具集。

使用restTemplate访问restful接口，（url,requestMap,ResponseBean.class）这三个参数分别代表REST请求地址、请求参数、HTTP响应转换成接收对象类型。

@LoadBalanced：表示ribbon负载均衡采用轮询策略。
