2.yaml

server:
      port: 8764
    spring:
      application:
        name: webfluxserver
    eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:8100/eureka/

3.Model

public class UserApiModel {
        private Integer id;
        private String name;
        private Boolean sex;
        private Integer age;
    
        public Integer getId() {
            return id;
        }
    
        public void setId(Integer id) {
            this.id = id;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public Boolean getSex() {
            return sex;
        }
    
        public void setSex(Boolean sex) {
            this.sex = sex;
        }
    
        public Integer getAge() {
            return age;
        }
    
        public void setAge(Integer age) {
            this.age = age;
        }
    }

4. service

@Component
    public class UserSerivceImpl {
        public List<UserApiModel> query(UserApiModel param)
        {
            List<UserApiModel> userApiModels=new ArrayList<>();
            userApiModels.add(param);
            for(int i=0;i<10;i++)
            {
                userApiModels.add(param);
            }
            try {
                Thread.sleep(10000);
            }catch (Exception ex)
            {
                ex.printStackTrace();
            }
            //处理数据
            return userApiModels;
        }
        public UserApiModel queryId(Integer id)
        {
            //处理数据
            return new UserApiModel();
        }
        public UserApiModel queryOne(UserApiModel param)
        {
            //处理数据
            return param;
        }
        public Integer edit(UserApiModel param)
        {
            //处理数据
            return 1;
        }
        public Integer add(UserApiModel param)
        {
            //处理数据
            return 1;
        }
    }

5.controller

@RestController
    @RequestMapping("user")
    public class UserController {
        @Autowired
        UserSerivceImpl userSerivce;
        @PostMapping("/query")
        public Flux<UserApiModel>query(UserApiModel model) {
            return Flux.fromIterable(userSerivce.query(model));
        }
        @PostMapping("/queryone")
        public Mono<UserApiModel>queryOne(UserApiModel model) {
    
            return Mono.justOrEmpty(userSerivce.queryOne(model));
        }
        @GetMapping("/queryid")
        public Mono<UserApiModel>queryId(Integer id) {
    
            return Mono.justOrEmpty(userSerivce.queryId(id));
        }
        @PostMapping("/add")
        public Mono<Integer> add(UserApiModel model) {
    
            return Mono.just(userSerivce.add(model));
        }
        @PostMapping("/edit")
        public Mono<Integer> edit(UserApiModel model) {
    
            return Mono.just(userSerivce.edit(model));
        }
    }
