Spring - Post Mapping-CodePudding

Is there a way that when you have a code:

@PostMapping("/test")
public boolean test(@RequestBody String data) {
    //code and stuff
}

You could send information in the post request url? for example

localhost:8080/test?username=username

CodePudding user response：

You can use the @RequestParam annotation.

@PostMapping("/test")
    public boolean test(@RequestBody String data, @RequestParam String username) {
    //code and stuff
}

If you need to call it something else you can also specify that

@RequestParam("username") String whatever

CodePudding user response：

You can mix request body and request params.

In your example, you can read the username request param this way:

@PostMapping("/test")
public boolean test(@RequestBody String data, @RequestParam String username) {
    //code and stuff
}

CodePudding user response：

Yes, just use @RequestParam:

@PostMapping("/test")
public boolean test(@RequestParam String username, @RequestBody String data) {
    //code and stuff
}

In the reference documentation we can read the following:

Supported for annotated handler methods in Spring MVC and Spring WebFlux as follows:

In Spring MVC, "request parameters" map to query parameters, form data, and parts in multipart requests. This is because the Servlet API combines query parameters and form data into a single map called "parameters", and that includes automatic parsing of the request body.

In Spring WebFlux, "request parameters" map to query parameters only. To work with all 3, query, form data, and multipart data, you can use data binding to a command object annotated with ModelAttribute.
