搭建Spring boot+mybatis框架

开发环境说明：idea2017.2.6+jdk8+maven3.5+绿色版mysql+绿色版mysql客户端（或者用Navicat for MySQL）

1、用Intellij idea工具创建spring boot；

可以根据自己的喜好修改Group和Artifact中的内容，

然后点击Next下一步

搭建Spring boot+mybatis框架

根据自己的意愿选择，如果不勾选MySQL、jdbc、mybatis；在后面可以自己添加配置文件

然后点击下一步-->点击finish即可。

2、点击直接生成pow.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            </plugin>
        </plugins>

  </build>
</project>

3、一次编写PO、Mapper、cotroller包下的java文件

搭建Spring boot+mybatis框架

MemberPO.java文件

搭建Spring boot+mybatis框架

MembersMapper接口

package com.example.demo.Mapper;

import com.example.demo.PO.MembersPO;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;


@Repository
public interface MembersMapper {


    @Select("SELECT id,openid,nickname,sex,prvoince,city,country,headimgurl,unionid,dengji,totime,priceID,create_time\n" +
            "FROM members\n" +
            "WHERE openid = #{openid}")
    MembersPO selectMembersinfoByOpenid(@Param("openid") String openid);
}

MembersController.java文件

package com.springbootkj.demo.controller;


import com.springbootkj.demo.PO.MembersPO;
import com.springbootkj.demo.mapper.MembersMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/showResult")
public class MembersController {

    @Autowired
    private MembersMapper membersMapper;

    @RequestMapping(value = "/show", method = {RequestMethod.GET,RequestMethod.POST})
    public MembersPO showResult(String openid){

        return membersMapper.selectMembersInfoByOpenid(openid);
    }




}

4、看一下application.properties的配置

#设置Tomcat端口 ，默认8080
server.port=8080

#设置Tomcat编码
server.tomcat.uri-encoding=UTF-8
#设置视图解析器路径
spring.mvc.view.prefix=/WEB-INF/views/
#设置视图解析器后缀
spring.mvc.view.suffix=.jsp

spring.datasource.url=jdbc:mysql://localhost:3306/testTable?useUnicode=true&characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=mysql
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

#页面的热加载
spring.thymeleaf.cache = false

5、DataSourceConfig文件

package com.springbootkj.demo.config;



import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;


@Configuration
@MapperScan(basePackages = "com.springbootkj.demo.mapper.MembersMapper", sqlSessionFactoryRef = "sqlSessionFactory")
public class DataSourceConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.hikari")
    public DataSource initDataSource(){
        return DataSourceBuilder.create().build();
    }


    @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(initDataSource());
        return factoryBean.getObject();

    }

    public SqlSessionTemplate sqlSessionTemplate() throws Exception {
        // 使用上面配置的Factory
        SqlSessionTemplate sessionTemplate = new SqlSessionTemplate(sqlSessionFactory());
        return sessionTemplate;
    }




}

6、MySQL数据库的配置

搭建Spring boot+mybatis框架

8、接口访问：http://localhost:8080/showResult/show?openid=oFNc6s8Z7l0nBgrZQ

id 1

openid oFNc6s8Z7l0nBgrZQ

nickname .OLDZ%87S.
sex 1
prvoince 辽宁
city 沈阳
country 中国
headimgurl httpss://wx.qlogo.cn/mmopen/PiajxOKDQffgHt5XiaZQMZqIAz/0
privilege 辽宁
unionid null
dengji 0
totime 0
priceID 8000
create_time 2018-06-12

到此Spring boot的框架的搭建基本完成。
