48: Chapter 5: develop admin management service: 1: create sub project [imooc news dev Service Admin], management service module;

explain ：

（1） Rationality of this blog ：

        ●  stay 【2： Chapter one ： Project brief introduction ：2： Project presentations ;】 in , We know that part of our project is " Management platform （ Or operation center ）"; This is actually , It is the background management system of the project ;

        ●  stay 【9： Chapter two ： Architecture back end project ：5：【 Polymerization Engineering 】 brief introduction ;】、【3： Chapter one ： Project brief introduction ：3： Project microservice architecture diagram ;】 in , It is known that we will separate management services ; Background management part of the project , Will be done in this module ;

        ●  therefore , This blog is to create 【imooc-news-dev-service-admin】 management service , This module ; 

（2）  additional ： If it's starting Tomcat and 【admin】 The service , When the port is occupied ; You can refer to 【tomcat When running java.net.BindException: Address already in use: JVM_Bind Error resolution 】 Go and see if the port is occupied , If it is occupied, you can try to close the process that occupies the program ;

One ：【admin management service 】 part , Description of content ;

（1） structure admin management service ;

（2） Article classification function ;

（3） Link management function ;

（4） User account management ;

（5） The content of the article is reviewed manually ;

          ●  Wait for the back , To develop the " Users publish articles " After function , Then develop this function ;

          ●  After the user publishes the article , There will be an automatic audit first , If the automatic approval fails, the manual approval will be carried out ;

（6）admin Management account number ;

          ●  backstage admin Management Center , You also need an account to log in ; It's just , We will not develop the registration function in the background ; because , Background administrator account , Generally, it is allocated manually ; namely , At the beginning , We will have an administrator account , Then this administrator account can create several administrator accounts , For others to use ;

          ●  Face login will also be involved here ; In limine , It will let users' faces be stored , Then when logging in later , You can use face login ;

Four ：【admin】 management service , Create a test HelloController, See if the project OK;

（1） First, the whole situation install Look at the whole project ;

（2） start-up 【admin】 The main startup class of the service ;

（3） Remember to open SwitchHost Open virtual domain name mapping ;

……………………………………………………

（4） Through the browser , visit /hello Interface ;

（5） additional ： If it's starting Tomcat and 【admin】 The service , When the port is occupied ; You can refer to 【tomcat When running java.net.BindException: Address already in use: JVM_Bind Error resolution 】 Go and see if the port is occupied , If it is occupied, you can try to close the process that occupies the program ;
