• map的映射

package com.kob.backend.controller.pk;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashMap;
import java.util.Map;

@RestController

@RequestMapping("/pk/")
public class BotInfoController {
    @RequestMapping("getbotinfo/")
    public Map<String,String> getBotInfo(){
        Map<String, String> map = new HashMap<>();
        map.put("name", "trigger");
        map.put("rateing", "1500");
        return map;
    }
}

Map， List里面用的都是尖括号

• 二者的嵌套

@RestController

@RequestMapping("/pk/")
public class BotInfoController {
    @RequestMapping("getbotinfo/")

    public List<Map<String,String>> getBotInfo(){
        List<Map<String,String>> list = new LinkedList<>();
        Map<String, String> bot1 = new HashMap<>();
        bot1.put("name", "trigger");
        bot1.put("rateing", "1500");

        Map<String, String> bot2 = new HashMap<>();
        bot2.put("name", "trigger");
        bot2.put("rateing", "1600");

        Map<String, String> bot3 = new HashMap<>();
        bot3.put("name", "trigger");
        bot3.put("rateing", "1700");

        list.add(bot1);
        list.add(bot2);
        list.add(bot3);

        return list;
    }
}

• 链接是通过controller来实现的 ：http://localhost:8080/pk/getbotinfo/
• 修改端口
• 

server.port=3000

变红是没有加到git里面
