Detailed explanation of common annotations for spring boot receiving requests

@RequestBody

Used to bind data in HTTP request bodies (such as JSON, XML, etc.) to parameters of the controller method

Example:

    @PostMapping("/status/{status}")
    public Result<String> startOrStop(@PathVariable("status") Integer status, Long id){
        (status,id);
        return ();
    }

@PathVariable

Used to receive path parameters (can specify parameter names)

Example:

    @PostMapping("/status/{status}")
    public Result<String> startOrStop(@PathVariable("status") Integer status, Long id){
        (status,id);
        return ();
    }

@RequestParam

Method parameters used to bind request parameters to controller

Example:

    @DeleteMapping
    public Result deleteByIds(@RequestParam List<Long> ids){
        (ids);
        return ();
    }

@DateTimeFormat

Format for specifying date and time so that it can be parsed correctly when converting request parameters of string type to date or time type.

Example:

    @RequestMapping("/meeting")
    public String scheduleMeeting(@RequestParam("meetingDate") @DateTimeFormat(iso = ) LocalDate meetingDate) {
        // Handle the logic of scheduling meetings        return "meetingScheduled";
    }
