springboot2.6.1 + mybatis2.2.1 + map

Mybatis Select 返回 Map

一、数据库使用Postgres

1.Docker Postgres 官方数据库镜像拉取与启动：

##拉取
docker pull postgres:14.1
##启动
docker run --privileged=true -d --name pg -e POSTGRES_PASSWORD=123456 -e POSTGRES_USER=postgres -p 5432:5432 -e TZ=PRC postgres:14.1

2.数据库备份命令

/usr/bin/pg_dump  --username=postgres -h 127.0.0.1 --create  --disable-triggers  -c --if-exists zhx 1>> zhx.sql

3.备份文件内容（zhx.sql）

--
-- PostgreSQL database dump
--

-- Dumped from database version 14.1 (Debian 14.1-1.pgdg110+1)
-- Dumped by pg_dump version 14.1 (Debian 14.1-1.pgdg110+1)

SET statement_timeout = 0;
SET lock_timeout = 0;
SET idle_in_transaction_session_timeout = 0;
SET client_encoding = 'UTF8';
SET standard_conforming_strings = on;
SELECT pg_catalog.set_config('search_path', '', false);
SET check_function_bodies = false;
SET xmloption = content;
SET client_min_messages = warning;
SET row_security = off;

DROP DATABASE IF EXISTS zhx;
--
-- Name: zhx; Type: DATABASE; Schema: -; Owner: postgres
--

CREATE DATABASE zhx WITH TEMPLATE = template0 ENCODING = 'UTF8' LOCALE = 'en_US.utf8';


ALTER DATABASE zhx OWNER TO postgres;

\connect zhx

SET statement_timeout = 0;
SET lock_timeout = 0;
SET idle_in_transaction_session_timeout = 0;
SET client_encoding = 'UTF8';
SET standard_conforming_strings = on;
SELECT pg_catalog.set_config('search_path', '', false);
SET check_function_bodies = false;
SET xmloption = content;
SET client_min_messages = warning;
SET row_security = off;

--
-- Name: zhx; Type: DATABASE PROPERTIES; Schema: -; Owner: postgres
--

ALTER DATABASE zhx CONNECTION LIMIT = 10;


\connect zhx

SET statement_timeout = 0;
SET lock_timeout = 0;
SET idle_in_transaction_session_timeout = 0;
SET client_encoding = 'UTF8';
SET standard_conforming_strings = on;
SELECT pg_catalog.set_config('search_path', '', false);
SET check_function_bodies = false;
SET xmloption = content;
SET client_min_messages = warning;
SET row_security = off;

SET default_tablespace = '';

SET default_table_access_method = heap;

--
-- Name: tbl_user; Type: TABLE; Schema: public; Owner: postgres
--

CREATE TABLE public.tbl_user (
    id integer NOT NULL,
    name character varying(255),
    age integer
);


ALTER TABLE public.tbl_user OWNER TO postgres;

--
-- Data for Name: tbl_user; Type: TABLE DATA; Schema: public; Owner: postgres
--

COPY public.tbl_user (id, name, age) FROM stdin;
1	李淳风	58
2	袁天罡	98
\.


--
-- Name: tbl_user tbl_user_pkey; Type: CONSTRAINT; Schema: public; Owner: postgres
--

ALTER TABLE ONLY public.tbl_user
    ADD CONSTRAINT tbl_user_pkey PRIMARY KEY (id);


--
-- PostgreSQL database dump complete
--

二、工程

1.项目结构

在这里插入图片描述

2.启动类

package com.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Description: 数据库测试
 *
 * @Author: zhx & moon hongxu_1234@163.com
 * @Date: 2022-01-19 21:48
 * @version: V1.0.0
 */
@SpringBootApplication
@MapperScan("com.demo.mapper")
public class PgsqlApplication {
    public static void main(String[] args) {
        SpringApplication.run(PgsqlApplication.class,args);
    }
}

3.数据库配置

package com.demo.config;

import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;

import javax.sql.DataSource;
import java.sql.SQLException;

4.Result处理句柄

package com.demo.mapper.session;

import org.apache.ibatis.session.ResultContext;
import org.apache.ibatis.session.ResultHandler;

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

/**
 * Description: 结果处理句柄
 *
 * @Author: zhx & moon hongxu_1234@163.com
 * @Date: 2022-01-19 23:06
 * @version: V1.0.0
 */
public class MapResultHandler implements ResultHandler {

    @SuppressWarnings("rawtypes")
    private final Map mappedResults = new HashMap();

    @SuppressWarnings("unchecked")
    @Override
    public void handleResult(ResultContext context) {
        @SuppressWarnings("rawtypes")
        Map map = (Map)context.getResultObject();
        // xml 配置里面的property的值，对应的列
        mappedResults.put(map.get("keys"), map.get("val") + "");
    }

    public Map getMappedResults() {
        return mappedResults;
    }
}

5.Session处理器

package com.demo.mapper.session;

import com.demo.mapper.DemoMapper;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.support.SqlSessionDaoSupport;
import org.springframework.context.annotation.DependsOn;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.Map;

/**
 * Description: PG SESSION
 *
 * @Author: zhx & moon hongxu_1234@163.com
 * @Date: 2022-01-19 23:00
 * @version: V1.0.0
 */
@Service
@DependsOn(value = {"dataSource"})
public class DemoSession extends SqlSessionDaoSupport {

    @Override
    @Resource
    public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) {
        super.setSqlSessionFactory(sqlSessionFactory);
    }

    @SuppressWarnings("unchecked")
    public Map<String,String> queryMap(){
        MapResultHandler handler = new MapResultHandler();
        this.getSqlSession().select(DemoMapper.class.getName()+".queryMap", handler);
        Map<String, String> map = handler.getMappedResults();
        return map;
    }
}

6.测试接口

package com.demo.controller;

import com.demo.mapper.session.DemoSession;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Map;

/**

 *
 * @Author: zhx & moon hongxu_1234@163.com
 * @Date: 2022-01-19 23:11
 * @version: V1.0.0
 */
@RestController
@RequestMapping("/demo")
@Slf4j
public class DemoController {

    private DemoSession demoSession;

    @Autowired
    public void setDemoSession(DemoSession demoSession){
        this.demoSession = demoSession;
    }

    @GetMapping("/map")
    public void query(){
        try{
            Map<String,String> map = demoSession.queryMap();
            map.forEach((k,v)->{
                log.info("姓名：{} 年龄：{}",k,v);
            });
        }catch (Exception e){
            log.error("",e);
        }
    }
}

7.Map接口

package com.demo.mapper;

import java.util.Map;

/**
 * 用户登录 MAPPER
 * @author  zhx & moon hongxu_1234@163.com
 * @date 2020/11/19 22:19
 * @version V1.0.0
 */
public interface DemoMapper {

    /**
     * 查询
     * @return
     */
    Map<String,String> queryMap();
}

8.Xml文件

<?xml version="1.0" encoding="UTF-8"?>
