4. Construction and registration of BeanDefinition
Foreword In the last article, we talked about the source code of the processBeanDefinition(ele, delegate) method: //This method requires two parameters: 1. The child node element parsed before, 2. The parser protected void processBeanDefinition(Element ele, BeanDefinitionParserDelegate delegate) { //Here the element object is parsed into a BeanDefinitionHolder object. This BeanDefinitionHolder is equivalent to a layer […]
3. The general process of Spring reading XML encapsulated BeanDefinition
Foreword: The previous article introduced the Resource interface and introduced the core content of the Spring IOC factory. This article will explain the general process of how Spring’s bottom layer reads XML through XmlBeanDefinitionReader and encapsulates it into a BeanDefinition. Spring reads the process of XML encapsulated BeanDefinition Call the XmlBeanFactory constructor. Spring reads XML […]

(Continued from 2.5Finite State Machine(II)) 2.5.24 Q3a:FSM [Exams/2014 q3fsm] Problem description Consider a finite state machine with inputs s and w. Assume that the FSM starts from a reset state called A, as shown below, the FSM remains in state A as long as s=0, and when s=1, the A state transitions to the B […]
Project practice: component scanning (5) – parse methods with GetMapping or PostMapping and finally encapsulate them into ControllerDefinition

Banana Pi BPI-M6 (Raspberry Pi 5 replacement) initial setup and firmware burning
Banana Pi BPI-M6: Initial setup and image burning First test of Banana Pi BPI-M6 In my previous article, I compared the hardware features of the Banana Pi BPI-M6 and the Raspberry Pi 5. Both have excellent hardware technology and shouldn’t have much of a problem in terms of performance. Today I wanted to test out […]
