    一、项目搭建

    1.父项目搭建

    步骤：

            1 选择maven项目作为父项目，修改为1.8之后直接点击next

            2  定义父项目的名称，修改Artifct Coordinates ---> GroupId 然后点击finsh就可以啦

            3 修改pom.xml

    1 选择maven项目作为父项目，修改为1.8之后直接点击next

     2  定义父项目的名称，修改Artifct Coordinates ---> GroupId 然后点击finsh就可以啦 

    3 修改pom.xml 

    1. "1.0" encoding="UTF-8"?>
    2. <project xmlns="http://maven.apache.org/POM/4.0.0"

    2.子项目的搭建

    搭建一个shop-common的maven子项目

    当建完这个项目时 父项目的pom.xml就会自动多出几行代码 ，这表示

    关联成功 

     

    shop-common的pom.xml

    1. "1.0" encoding="UTF-8"?>
    2. <project xmlns="http://maven.apache.org/POM/4.0.0"
    3.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    4.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    创建springboot项目： 

     

    直接选择next，然后finsh就可以了 

     以同样的方式创建一下三个

     pom.xml

    1. "1.0" encoding="UTF-8"?>
    2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    3.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    4.  
    5.     <parent>
    6.         <artifactId>spcloud-shopartifactId>
    7.         <groupId>com.zkinggroupId>
    8.         <version>1.0-SNAPSHOTversion>
    9.     parent>
    10.  
    11.     <modelVersion>4.0.0modelVersion>
    12.     <artifactId>shop-orderartifactId>
    13.  
    14.     <dependencies>
    15.         
    16.         <dependency>
    17.             <groupId>org.springframework.bootgroupId>
    18.             <artifactId>spring-boot-starter-webartifactId>
    19.         dependency>
    20.         
    21.         <dependency>
    22.             <groupId>com.zkinggroupId>
    23.             <artifactId>shop-commonartifactId>
    24.             <version>1.0-SNAPSHOTversion>
    25.         dependency>
    26.     dependencies>
    27.  
    28. project>

    =====================以上的基本配置完成=========================

     二、项目展示

    写入实体类

     order

    1. package com.zking.model;
    2.  
    3. import lombok.AllArgsConstructor;
    4. import lombok.Data;
    5. import lombok.NoArgsConstructor;
    6.  
    7.  
    8. @Data
    9. @AllArgsConstructor
    10. @NoArgsConstructor
    11. public class Order {
    12.     private Long oid;//订单id
    13.  
    14.     //用户
    15.     private Integer uid;//用户id
    16.     private String username;//用户名
    17.  
    18.     //商品
    19.     private Integer pid;//商品id
    20.     private String pname;//商品名称
    21.     private Double pprice;//商品单价
    22.  
    23.     //数量
    24.     private Integer number;//购买数量
    25. }

    Product

    1. package com.zking.model;
    2.  
    3. import lombok.AllArgsConstructor;
    4. import lombok.Data;
    5. import lombok.NoArgsConstructor;
    6.  
    7.  
    8. @Data
    9. @NoArgsConstructor
    10. @AllArgsConstructor
    11. public class Product {
    12.     private Integer pid;//主键
    13.  
    14.     private String pname;//商品名称
    15.     private Double pprice;//商品价格
    16.     private Integer stock;//库存
    17. }

    User

    1. package com.zking.model;
    2.  
    3. import lombok.AllArgsConstructor;
    4. import lombok.Data;
    5. import lombok.NoArgsConstructor;
    6.  
    7.  
    8. //用户
    9. @Data//不再去写set和get方法
    10. @NoArgsConstructor
    11. @AllArgsConstructor
    12. public class User {
    13.     private Integer uid;//主键
    14.     private String username;//用户名
    15.     private String password;//密码
    16.     private String telephone;//手机号
    17. }

    编写aplication.yml

     

     

     

     

    编写controller层

    shop-user：

    1. package com.zking.shopuser.controller;
    2.  
    3. import com.zking.model.User;
    4. import org.springframework.web.bind.annotation.PathVariable;
    5. import org.springframework.web.bind.annotation.RequestMapping;
    6. import org.springframework.web.bind.annotation.RestController;
    7.  
    8. /**
    9.  * @author 小何吖
    10.  * @create 2022-11-24 15:47
    11.  */
    12.  
    13. @RestController
    14. @RequestMapping("/user")
    15. public class UserController {
    16.     @RequestMapping("/get/{id}")
    17.     public User get(@PathVariable("id") Integer id){
    18.         return new User(id,"骚强","5438","3838438");
    19.     }
    20. }

     运行，选中写了controller的运行

     

     

     shop-product：

    1. package com.zking.shopproduct.controller;
    2.  
    3. import com.zking.model.Product;
    4. import org.springframework.web.bind.annotation.PathVariable;
    5. import org.springframework.web.bind.annotation.RequestMapping;
    6. import org.springframework.web.bind.annotation.RestController;
    7.  
    8. /**
    9.  * @author 小何吖
    10.  * @create 2022-11-24 15:52
    11.  */
    12.  
    13. @RestController
    14. @RequestMapping("/product")
    15. public class ProductContoller {
    16.     @RequestMapping("/get/{pid}")
    17.     public Product get(@PathVariable("pid") Integer pid){
    18.         return new Product(pid,"金瓶梅",66d,20);
    19.     }
    20.  
    21. }

     

     shop-order:

    1. package com.zking.shoporder.controller;
    2.  
    3. import com.zking.model.Order;
    4. import com.zking.model.Product;
    5. import com.zking.model.User;
    6. import org.springframework.beans.factory.annotation.Autowired;
    7. import org.springframework.web.bind.annotation.PathVariable;
    8. import org.springframework.web.bind.annotation.RequestMapping;
    9. import org.springframework.web.bind.annotation.RestController;
    10. import org.springframework.web.client.RestTemplate;
    11.  
    12. /**
    13.  * @author 小何吖
    14.  * @create 2022-11-24 15:43
    15.  */
    16. @RestController
    17. @RequestMapping("/order")
    18. public class OrderController {
    19.  
    20.  
    21.     @Autowired
    22.     private RestTemplate restTemplate;
    23.  
    24.     @RequestMapping("/get/{uid}/{pid}")
    25.     public Order get(@PathVariable("uid") Integer uid
    26.                      ,@PathVariable("pid") Integer pid){
    27.         /*
    28.          *要在订单微服务调用 用户微服务、商品微服务、也就意味着跨项目调用
    29.          *
    30.          */
    31.         User user = restTemplate.getForObject("http://localhost:8070/user/get/" + uid, User.class);
    32.         Product product = restTemplate.getForObject("http://localhost:8080/product/get/" + pid, Product.class);
    33.         Order order = new Order();
    34.         order.setUsername(user.getUsername());
    35.         order.setUid(user.getUid());
    36.         order.setPprice(product.getPprice());
    37.         order.setPname(product.getPname());
    38.         order.setPid(product.getPid());
    39.         order.setOid(System.currentTimeMillis());
    40.         order.setNumber(product.getStock());
    41.         return order;
    42.     }
    43. }

     

     

    这就是简单的微服务，没有连接数据库的简单应用
