    @PostMapping("/dada")
    public Object getEmail(@RequestBody @Valid AEmail aemail) {

        System.out.println("aemail:" + aemail.email);

        return "fff";
    }


    public static class AEmail {
        @Email(message = "wrong email format")
        String email;

        public AEmail() {
        }

        public String getEmail() {
            return email;
        }

        public void setEmail(String email) {
            this.email = email;
        }
    }

测试代码：

import requests
import json

adata = {
    "email":"hi@hi.com"
}

aheaders = {'Content-Type': 'application/json'}

url = "http://localhost:5002/dada"

response = requests.post(url, headers=aheaders, data = json.dumps(adata))

print response.text

测试结果（email 格式错误时）：

$ python ../../../../py_post.py
