Tecnical points

1. @RequestParam and @RequestBody annotations

@RequestParam annotation is used to bind request parameters to a method parameter. It is used to map request parameters to method parameters. The request parameter name must match the method parameter name.

@RequestBody annotation is used to bind the request body to a method parameter. It is used to map the request body to a method parameter. The request body can be any type of data, such as JSON, XML, or plain text.

2. Parameter of @RequestParam

• required: boolean value, default value is true. If required is true, the parameter must exist in the request. If required is false, the parameter is optional.
• defaultValue: default value of the parameter. If the parameter does not exist in the request, the defaultValue is used.
• name: parameter name. If name is not specified, the parameter name is used.

3. @Primary annotation

@Primary annotation is used to specify the primary bean. If there are multiple beans of the same type, the @Primary annotation is used to specify the primary bean.

4. @PostConstruct and @PreDestroy annotations

@PostConstruct annotation is used to execute some initialization code after the constructor is called.

@PreDestroy annotation is used to execute some cleanup code before the object is destroyed.
