1、函数式：

//1、若是form-data形式提交表单内容，即Content-Type: application/x-www-form-urlencoded;可以通过ServerWebExchange 获取

$.ajax({

type: 'POST',

url: "/post/findform",

data: {

name: "aa",

sex:"n"

},

dataType: "json",

success: function (data) {

console.log(data);

},error:function () {

console.log("error");

}

});

// route:

@Configuration

public class PostRouter {

@Bean

public RouterFunction postroute(PostHandler handler) {

return RouterFunctions.route(RequestPredicates.POST("/post/findform")

.and(RequestPredicates.accept(MediaType.APPLICATION_FORM_URLENCODED)),handler::findform);

}

}

// handle：

public Mono findform(ServerRequest request){

// 获取form data,在方法中添加ServerWebExchange对象，使用方法getFormData

ServerWebExchange exchange = request.exchange();

Mono> formData =exchange.getFormData();

return formData.flatMap(map -> {

System.out.println(map.get("name").get(0));

System.out.println(map.get("sex").get(0));

return ServerResponse.ok().contentType(MediaType.APPLICATION_STREAM_JSON)

.body(BodyInserters.fromObject(map));

});

}

// 2、若是application/json的形式提交表单

$.ajax({

type: 'POST',

url: "/post/findjson",

data: JSON.stringify({

"name": "aa"

}),

contentType:"application/json",

dataType: "json",

success: function (data) {

console.log(data);

},error:function () {

console.log("error");

}

});

// route:

@Configuration

public class PostRouter {

@Bean

public RouterFunction postroute(PostHandler handler) {

return RouterFunctions.route(RequestPredicates.POST("/post/findjson")

.and(RequestPredicates.accept(MediaType.APPLICATION_JSON)),handler::find)

}

}

// handle:直接通过map映射获取

public Mono find(ServerRequest serverRequest){

Mono body = serverRequest.bodyToMono(Map.class);

return body.flatMap(map -> {

String name = (String) map.get("name");

System.out.println(name);

return ServerResponse.ok().contentType(MediaType.APPLICATION_STREAM_JSON)

.body(BodyInserters.fromObject(name));

});

}

2、注解式

若是get请求，可通过@RequestParam或直接获取

// get形式提交，下面两种形式都可以直接获取到请求参数

@GetMapping("/save")

private Mono save(final User user){

System.out.println(user.getName());

return Mono.justOrEmpty(userService.save(user));

}

@GetMapping("/save1")

private Mono save(@RequestParam final String name,@RequestParam final String sex){

System.out.println(name);

return Mono.justOrEmpty(userService.save(new User(name,sex)));

}

若是Post请求，当请格式分别为json或表单格式,json使用@RequestBody获取，form格式通过实体映射或使用ServerWebExchange获取

$.ajax({

type: 'POST',

url: "/postController/json",

data: JSON.stringify({

"name": "aa",

"sex":"m"

}),

contentType:"application/json",

dataType: "json",

success: function (data) {

console.log(data);

},error:function () {

console.log("error");

}

});

$.ajax({

type: 'POST',

url: "/postController/jsonS",

data: JSON.stringify({

"name": "aa",

"sex":"m"

}),

contentType:"application/json",

dataType: "json",

success: function (data) {

console.log(data);

},error:function () {

console.log("error");

}

});

$.ajax({

type: 'POST',

url: "/postController/form",

data: {

name: "bb",

sex:"m"

},

dataType: "json",

success: function (data) {

console.log(data);

},error:function () {

console.log("error");

}

});

$.ajax({

type: 'POST',

url: "/postController/formS",

data: {

name: "bb",

sex:"m"

},

dataType: "json",

success: function (data) {

console.log(data);

},error:function () {

console.log("error");

}

});

// controller

@RestController

@RequestMapping("/postController")

public class PostController {

/**

* 通过@RequestBody获取提交的application/json数据

* @param

* @return

*/

@PostMapping(value = "/json",produces = MediaType.APPLICATION_STREAM_JSON_VALUE)

public Mono json(@RequestBody String user) {

System.out.println("json:"+user);

return Mono.just(user);

}

/**

* 通过实体映射获取post的请求体 application/json数据

* @param user

* @return

*/

@PostMapping(value = "/jsonS",produces = MediaType.APPLICATION_STREAM_JSON_VALUE)

public Mono jsonS(@RequestBody User user) {

System.out.println("jsonS:"+ user);

return Mono.just(user.toString());

}

/**

* 通过实体映射获取表单数据

* request：Content-Type: application/x-www-form-urlencoded

* @param user

* @return

*/

@PostMapping(value = "/form", produces = MediaType.APPLICATION_STREAM_JSON_VALUE)

public Mono save(User user) {

System.out.println("form:"+user);

return Mono.justOrEmpty(user);

}

/**

* 通过ServerWebExchange获取表单数据

* request：Content-Type: application/x-www-form-urlencoded

* @param exchange

* @return

*/

@PostMapping(value = "/formS", produces = MediaType.APPLICATION_STREAM_JSON_VALUE)

public Mono save(ServerWebExchange exchange) {

Mono> formData =exchange.getFormData();

return formData.flatMap(map -> {

System.out.println("formS："+map);

return Mono.justOrEmpty(map.toString());

});

}

}
