What is @PostMapping annotation in Spring Web MVC?

问题

For what purpose @PostMapping annotation is used in Spring MVC?

回答1:

@PostMapping is a composed annotation that acts as a shortcut for @RequestMapping(method = RequestMethod.POST).

@PostMapping annotated methods handle the HTTP POST requests matched with given URI expression. e.g.

@PostMapping(path = "/members", consumes = "application/json", produces = "application/json")
public void addMember(@RequestBody Member member) {
    //code
}

Follows this :example

Hope this helps..!

回答2:

Spring Framework 4.3 has introduced @PostMapping annotation.

@PostMapping is a composed annotation that acts as a shortcut for

@RequestMapping(method = RequestMethod.POST)

Similarly the following annotations are available:

@GetMapping  
@PutMapping
@DeleteMapping
@PatchMapping

These annotations can improve the readability of code.
