Maven学习(九）Maven项目SpringCloud微服务工程构建（基于单一案例的逻辑）

源代码地址：https://gitee.com/hs-sunrui/maven_study_micro.git

一、创建工程

1.创建工程

工程名	地位	说明
demo-maven-ms	父工程	总体管理各个子工程
demo01-gateway	子工程	网关
demo02-user-auth-center	子工程	用户中心
demo03-emp-manager-center	子工程	员工数据维护中心
demo04-memorials-manager-center	子工程	奏折数据维护中心
demo05-work-manager-center	子工程	批阅奏折工作中心
demo06-mysql-data-provider	子工程	mysql数据提供者
demo07-redis-data-provider	子工程	Redis数据提供者
demo08-base-api	子工程	声明feign接口
demo09-base-entity	子工程	实体类
demo-base-util	子工程	工具类

2.建立工程间依赖关系

二、父工程管理依赖

三、打基础

1.demo10-base-util

把前面工程的工具类和异常类拷贝过来

package com.sr.maven.exception;

public class LoginFailException extends RuntimeException{
   

    public LoginFailException() {
   
        super();
    }

    public LoginFailException(String message) {
   
        super(message);
    }

    public LoginFailException(String message, Throwable cause) {
   
        super(message, cause);
    }

    public LoginFailException(Throwable cause) {
   
        super(cause);
    }

    protected LoginFailException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
   
        super(message, cause, enableSuppression, writableStackTrace);
    }
}

package com.sr.maven.util;

public class ImperialCourtConst {
   

    public  static final String LOGIN_FAIL_MESSAGE = "帐号、密码错误，不可进宫！";

    public static final String ACCESS_DENIED_MESSAGE = "宫闱禁地，不可擅入！";

    public static final String LOGIN_EMP_ATTR_NAME = "loginInfo";
}
