> 实践+熟练

接下来创建common（公共工程）gonggonggongcheng

new Module 啥都行 创建以后删掉test、resources、留pom和main/java

> common的pom文件

<?xml version="1.0" encoding="UTF-8"?>
    <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>
            <artifactId>demo-parent</artifactId>
            <groupId>com.zongyi</groupId>
            <version>1.0-SNAPSHOT</version>
            <relativePath>../demo-parent/pom.xml</relativePath>
        </parent>
    
        <artifactId>demo-common</artifactId>
        <packaging>jar</packaging>
    
    </project>

创建User类

@Data用来自动生成getset方法 依赖：

<dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.6</version>
    </dependency>

### common完成 ucenter ###

然后ucenter开发DAO Service Controller 和web项目一样，只是ucenter的控制器方法接收对象时有变化

ucenter引入公共依赖  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4NjI2NTk1_size_16_color_FFFFFF_t_70 2]

ucenter–controller变化，这是声明收到的是JSON字符串，将会自动转换为对象

### ucenter完成 webbase ###

和ucenter一样添加公共依赖  
  
同样是service接口没有实现，注解有变化

首先service

@RequestBody(required = false)检查是否为必填项

然后controller

最后测试

[http://127.0.0.1:9992/webUserController/addUser?username=zongyi][http_127.0.0.1_9992_webUserController_addUser_username_zongyi]  
  
显示false

[http://127.0.0.1:9992/webUserController/addUser?username=zongyi&password=123456][http_127.0.0.1_9992_webUserController_addUser_username_zongyi_password_123456]  
  
显示success

到此SpringCloud的实践完成，请在此基础上无限扩展
