NHK EASY NEWS Backend Server

Important

This server will be refactoring by using Spring Boot instead of Spring MVC

Introduction

This is a backend server that return the news list which scrawl from NHK Easy News website. Implement with Spring Rest Framework and deploy on AWS.

Api

• /api/news : return a list of the news_list
• /api/daily_update_news : feed database with the latest news
• /api/news/:id : return a specific news with id = :id
• **Don't Recommand to Use !!! **/api/update_all_news : feed database with all news if database being truncated

MySql Database

1. Create a news_list table:

   CREATE TABLE news_list (
     `news_id` char(25) PRIMARY KEY NOT NULL,
     `title` TEXT NOT NULL,
     `title_with_ruby` TEXT,
     `news_img_url` TEXT,
     `news_url` TEXT,
     `pulic_date` TEXT
   )

File Structure

packages/
├── server
│ 	└── NewsListServer.java
├── Entity
│	└── NewsList.java
├── Main
	└── Main.java
	

Note:

1. On the NewsListDAOImpl, on geNewsList() 's HQL from NewsList, NewsList is the classname that in the Entity instead of Table Name in MYSQL !!!

2. Deploying onto AWS, if the error goes like "Incorrect string value:\xF0\x90\x8D..." that means the collation of columns of table is not utf-8, ( it probably is 'latin' ), using SHOW FULL FIELDS FROM news_list to check that, and here is my solution:

   ALTER table `news_list` DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_unicode_ci; 
   
   ALTER TABLE `news_list` MODIFY news_id char(20) CHARACTER SET utf8 COLLATE utf8_unicode_ci;
   
   ALTER TABLE `news_list` MODIFY title text CHARACTER SET utf8 COLLATE utf8_unicode_ci;
   
   ALTER TABLE `news_list` MODIFY title_with_ruby text CHARACTER SET utf8 COLLATE utf8_unicode_ci;
   
   ALTER TABLE `news_list` MODIFY news_image_url text CHARACTER SET utf8 COLLATE utf8_unicode_ci;
   
   ALTER TABLE `news_list` MODIFY news_url text CHARACTER SET utf8 COLLATE utf8_unicode_ci;
   
   ALTER TABLE `news_list` MODIFY public_date text CHARACTER SET utf8 COLLATE utf8_unicode_ci;
   

   Need to think about that when creating the table !!!

3. When injecting data into databse, seeing all the data become question mark, reference: https://blog.csdn.net/qq_36381640/article/details/79185358,https://blog.csdn.net/violet_echo_0908/article/details/51498829, and ALTER TABLE Table CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
