Today on May 1st, I found my neighbor is moving! After questioning, it was learned that the neighbor had changed a larger house.
Three years ago, we and our neighbors bought a house at about the same time. Three years later, someone else sold the house for more than 2 million, and then changed a large house for more than 4 million. And I, let alone the house, I haven't been willing to change a few sets of clothes!
Talking too much is tears, this is the stark gap. Like many programmers in real life, they usually don't feel it. Only when there is a big difference can people realize the existence of the gap.
My baby suddenly said to me today that my father is not worthy of May 1st, even my progress is greater than yours. I don't know, I am taken aback. The baby has been learning English and literacy for the past two years, and now I read articles better than me! So, May Day really can't relax!
The article posted two days ago caused extensive discussion in the group, and many people asked me if I have any new video tutorial updates. Therefore, taking the May Day and reading less, I will update everyone with the latest, new video tutorials in 2020!
Have you ever been hurt by JVM?
The online system is suddenly stuck, unable to access or even directly OOM! I want to solve the online JVM GC problem, but I can't get started...

Before the interview, I memorized the concept of JVM principles, but I was asked about the actual situation. How to tune JVM parameters, how to solve GC, OOM problems in the project...

After talking about SpringCloud, some netizens replied to me, the SSM used in the project now, is there a video tutorial on SSM.
Are you using SSM for the old project?
The crowdfunding management system is a single architecture based on SSM integration. It uses SpringSecurity for permission control, zTree to achieve tree structure data display on the page, and paging through MyBatis's PageHelper plug-in. The exception mapping based on SpringMVC implements a set of general error message management mechanism, and achieves the compatibility of ordinary requests and Ajax requests.
Although the framework is old, the five internal organs of technology and business are complete, and the interface is more beautiful. Reply to "crowdfunding" in the official account to get free video tutorials and project source code.

A set of online education, the back-end interface part of the online college system, uses the currently popular SpringBoot+SpringCloud for microservice architecture, and uses Feign, Gateway, Hystrix, and Alibaba's Nacos to build the basic environment of the project. The project also uses MyBatisPlus to operate the persistence layer, uses OAuth2+JWT to achieve distributed access, and integrates SpringSecurity to perform authorization control in the project. In addition, Alibaba's EasyExcel was used in the project to implement read and write operations on Excel, Redis was used for home page data caching, Git was used for code version control, and Swagger was integrated to generate interface documents. The front-end part of the system uses the mainstream front-end framework Vue, uses Es6 development specifications, adopts a modular development model, builds the page environment using the Nuxt framework and vue-admin-template template, and uses Element-ui for page layout. In the front-end environment, Npm is used for dependency management, Babel is used for code conversion, Webpack is used for packaging of static resources, axios is used for Ajax request calls, and ECharts is used for data chart display.
