java 发布https接口

证书生成命令：

keytool -genkey -alias tomcat -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 3650

生成的证书 “keystore.p12” 放到resources目录下：

├─main
│  ├─java
│  │  └─com
│  │      └─xasj
│  │          └─cpsscheduler
│  └─resources
│      ├─static
│      └─templates
│      └─keystore.p12

application.yml 配置文件添加：

server:
  port: 8000
  ssl:
    key-store: classpath:keystore.p12
    key-store-password: 123456
    key-store-type: PKCS12
    key-alias: tomcat

编写测试类：

@RestController
public class TestController {

    @GetMapping("/test")
    public Map<String,Object> testMap(){
        Map map = new HashMap(2);
        map.put("1","a");
        map.put("2","b");
        return map;
    }
}

启动项目后，访问地址：

https://127.0.0.1:8000/test

响应结果：

{
    "1": "a",
    "2": "b"
}

访问地址：

http://127.0.0.1:8000/test

响应结果：
