Practical practice of sending emails with springboot Preface: In our actual project, there are some requirements related to the function of sending emails using mailboxes. The Spring framework provides an abstraction for sending emails using the JavaMailSender interface, and Spring Boot provides automatic configuration and startup modules for it. Therefore, it is relatively simple for […]

Use JMeter to simulate multiple IPs to send requests (IP spoofing)
Preface: If you are proficient in LoadRunner, you can directly use LoadRunner for IP spoofing. Here is an introduction to how to use JMeter for IP spoofing. IP spoofing usage scenarios 01. How to set up IP spoofing in JMeter 1. Obtain available IP Before configuring IP spoofing, you need to obtain unoccupied IP addresses […]

Spring boot email sending function
Email sending is a very common function. It is used for identity authentication during registration, sending important notifications, etc. Sun provides JavaMail to implement email sending, but the configuration is cumbersome. Spring provides JavaMailSender to simplify email configuration, and Spring Boot provides MailSenderAutoConfiguration further simplifies email sending. This article will introduce how Spring Boot implements […]
kafka: partitioning strategy for producers to send messages
In order to increase the scalability of the system, Kafka introduces the concept of partitioning. The partitioning mechanism in Kafka refers to dividing each topic into multiple partitions (Partitions), and each partition is an ordered set of message logs. Each message under a topic will only be saved in a certain partition, and will not […]
Asynchronously send logs to remote server in Python
background The most common way to use logs in Python is to output logs in the console and files. The logging module also provides corresponding classes that are very convenient to use. However, sometimes we may have some needs, such as How to achieve this requirement by sending logs to the remote end or directly […]

STM32 USART serial port sends + receives data
Introduction to communication protocols Communication interface The purpose of communication: transfer data from one device to another device, expand the hardware system Communication protocol: Establish the rules for communication, and both parties in the communication send and receive data according to the protocol rules. Synchronous communications typically include clock signals. Simplex communication means that data […]
