The main framework of the project directory spike
1.java directory
All config configuration information
controller
exception all business exceptions
mapper
service
rabbitmq
redis redis Cache
validator back-end verification
bean: data transport layer comprises: mysql and redis
util: Kit
dto: Data Transfer Object
Spike system logic
Achieve technical points
1.MD5
Achieve the user's password is encrypted before it is saved to the database
2. unified global exception handling
By intercepting all exceptions, various anomalies corresponding processing
3. Page Caching
Redis in the cache manually rendered html page
WebContext ctx = new WebContext(request, response, request.getServletContext(), request.getLocale(), model.asMap()); html = thymeleafViewResolver.getTemplateEngine().process("goods_detail", ctx);
4. solve the overbought
