1-SpringCloudAlibaba项目搭建

我们先来搭建一个项目架子，后面再慢慢的往里面填充我们需要的各种组件

首先我新建一个项目（File New Project）

![在这里插入图片描述][a6fd1ee4efca4a6e81e420cc74943e90.png]

创建我们的父工程，选择左边Sprig Initializr类型的，注意几个箭头的位置，点击Next

![在这里插入图片描述][0c620679b1824101a6208359ff30f357.png]

啥也不选直接完成就好了，后面反正要改配置文件

![在这里插入图片描述][e12378d938184bf7910242c4daf1bc3d.png]

生成后目录如下，如果有其它东西删了就好，注意项目的jdk版本和maven库

打开pom文件直接覆盖

                </dependency>
            </dependencies>
        </dependencyManagement>
    
    </project>

添加子项目模块order（File New Module）

![在这里插入图片描述][3c3420023ac3488da5f777eb227de9e9.png]

这里我们选择maven类型的，创建项目  
idea2023多了个Archetype不知道干啥的，我们选org.apache.maven.archetypes:maven-archetype-quickstart

![在这里插入图片描述][ff3ca70c4ecb407c8620fbab4eae0197.png]

还是直接覆盖pom文件

<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">
        <modelVersion>4.0.0</modelVersion>
        <parent>
            <groupId>com.sakura.springcloud</groupId>
            <artifactId>springcloudalibaba</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </parent>
    
        <artifactId>order</artifactId>
        <packaging>jar</packaging>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
        </dependencies>
    </project>

同样的方式我们创建另一个子项目模块stock  
改一下pom文件

<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/maven-v4_0_0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <parent>
            <groupId>com.sakura.springcloud</groupId>
            <artifactId>springcloudalibaba</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </parent>
    
        <artifactId>stock</artifactId>
        <packaging>jar</packaging>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
        </dependencies>
    </project>

我们完善一下项目，结构如下，有多余的内容直接删掉就好

![在这里插入图片描述][b50ad5320ba043849582e6ab769a46d2.png]

order的OrderApplication启动文件：

package com.sakura.order;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.web.client.RestTemplateBuilder;
    import org.springframework.context.annotation.Bean;
    import org.springframework.web.client.RestTemplate;
    
    /**
     * @author Sakura
     * @date 2023/7/19 11:43
     */
    @SpringBootApplication
    public class OrderApplication {
        
    
        public static void main(String[] args) {
        
            SpringApplication.run(OrderApplication.class, args);
        }
    
    	// 这里为了测试随便写的不要在意
        @Bean
        public RestTemplate restTemplate(RestTemplateBuilder builder) {
        
            RestTemplate restTemplate = builder.build();
            return restTemplate;
        }
    }

order的OrderController文件：

package com.sakura.order.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.web.client.RestTemplate;
    
    /**
     * @author Sakura
     * @date 2023/7/19 11:25
     */
    @RestController
    @RequestMapping("/order")
    public class OrderController {
        
    
        @Autowired
        RestTemplate restTemplate;
    
        @RequestMapping("/add")
        public String add(){
        
            System.out.println("下单成功");
            // 在orde里面调用stock服务
            String msg = restTemplate.getForObject("http://localhost:8011/stock/reduct", String.class);
            return "下单成功" + msg;
        }
    
    }

order的application.yml文件

server:
      port: 8010

同样的对应的stock模块文件  
stock的StockApplication启动文件

package com.sakura.stock;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /**
     * @author Sakura
     * @date 2023/7/19 11:43
     */
    @SpringBootApplication
    public class StockApplication {
        
    
        public static void main(String[] args) {
        
            SpringApplication.run(StockApplication.class, args);
        }
    
    }

stock的StockController文件

package com.sakura.stock.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @author Sakura
     * @date 2023/7/19 11:35
     */
    @RestController
    @RequestMapping("/stock")
    public class StockController {
        
    
        @RequestMapping("/reduct")
        public String reduct(){
        
            System.out.println("扣减库存");
            return "扣减库存";
        }
    
    }

stock的application.yml文件

server:
      port: 8011

启动两个服务，在浏览器里输入：http://localhost:8010/order/add  
出现下面页面说明基础服务搭建成功
