项目实战之乐优商城01后台项目搭建、测试

项目的基本结构及功能如下图所示，这里使用maven构建项目，然后手动导入依赖，不使用Spring Initializr快速创建是为了让项目没有那没多花里胡哨的依赖，自己添加更容易管理

下面是各个模块的pom.xml和application.yml(因为是初始工程，所以有些模块没有引入依赖和规定一些配置，因此就不一一列出)

测试

运行

访问：localhost:10086 (服务注册中心)

鼠标放在链接上面，浏览器底部会弹出一个地址，因为我们导入了这个依赖，这就是actuator提供的接口

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

我们点击访问：

因为我们没有添加信息，所以是一个空的json，但是可以肯定的是：我们能够访问到item-service了。

接下来我们通过路由访问试试，根据路由规则，我们需要访问的地址是：

http://localhost:10010/api/item/actuator/info
