Controller

新增一個Controller 新Class

初始狀態如下

package com.example.demo;

public class MailController {

}

使用註解定義為Controller

在Class上加入@Controller，並依照提示import packages

package com.example.demo;

import org.springframework.stereotype.Controller;

@Controller
public class MailController {

}

新增要成為接口的Method

@Controller
public class MailController {
    public String mailGet(){
      return "Post Mail Get OK";
    }

    public String mailSet(){
      return "Post Mail Set OK";
    }
}

使用註解定義Method接收Request

使用@RequestMapping設定路由

@Controller
public class MailController {
    @RequestMapping(value="/api/mail/get", method = RequestMethod.POST)
    public String mailGet(){
      return "Post Mail Get OK";
    }

    @RequestMapping(value="/api/mail/set", method = RequestMethod.POST)
    public String mailSet(){
      return "Post Mail Set OK";
    }
}

使用註解定義回傳值為ResponseBody

@Controller
public class MailController {
    @RequestMapping(value="/api/mail/get", method = RequestMethod.POST)
    public @ResponseBody String mailGet(){
      return "Post Mail Get OK";
    }

    @RequestMapping(value="/api/mail/set", method = RequestMethod.POST)
    public @ResponseBody String mailSet(){
      return "Post Mail Set OK";
    }
}

使用Postman檢視

啟動Spring Boot App，順利啟動後Console資訊：

Tomcat started on port(s): 8080 (http)

故以 localhost:8080 接上@RequestMapping(value="該路由路徑"

Get

在回應的Body中回覆"Post Mail Get OK"

Set

在回應的Body中回覆"Post Mail Set OK"

建立基礎路由與接收成功
