Assalomu alaykum. SpringMVC projectda Tomcat ishlayapti. Lekin Tomcat controllerni kora olmayapti. Yani localhostni uzini yozganda HelloWorld chiqyapti. Lekin controllerdagi url lar qoshilganida postman 404 oshibka beryapti. Shuni qanday tog'irlasam bo'ladi. Javob uchun oldindan rahmat

Assalomu Aleykum

Savol: Proyekt ni serverga Yuborgan requestlarni Yozib yuradigon Method bor Repositorydan Userni get qilib Request date bilan billa save qilib qo'yadi.

Agar 1 minutda Serverga 200 ta request borsa requestlarni yozib yuradigon method bilan billar 400 ta bo'ladi

bu daynoy nagruska shuni optimal qilish kerak(tools, technology, library) bo'lsa aytasngiz yaxshi bo'lar edi

Bu ishni qilishdan maqsad Userlarni Qachon Qancha vaqt ishlatganini bilish !

Jaboblar uchun oldindan rahmat :)

Assalomu alaykum. Spring bootda netty socket.io bilan ishlaganlar bormi. Agar netty soket ishlatilgan proyektni local ishlatsam muammosiz ishlamoqda lekin build qilib serverga qo'ysam unda connection qilib bo'lmayapti(proyet serverda ham muammosiz run bo'lmoqda). Bu muammo nimadan kelib chiqishi mumkin yoki serverdanmi?

⚠️ Spring Boot: Don't fall into this trap with @Transactional ! ⚠️

1️⃣ No need to call .save() after modifying an entity: Spring Data JPA detects changes and flush() them automatically. Less code, better performance! πŸš€

πŸ‘‰ This error is common and has an impact on the stability and performance of your application. Have you ever encountered it? πŸ‘‡πŸ’¬
