【开发环境】

1.操作系统：windows

2.开发工具：IDEA

3.java -version

一、【新建项目】

File→New Project→Spring Initializr，选择下一步

添加组织信息，然后下一步

选择SQL→Mybatis Framework，然后下一步

点击finish

项目创建完毕，目录结构如下，可以对目录结构做个优化，删除标红部分。

二、【目录结构调整】

修改src-main-java下的文件名为cn.com.springboot

项目完整目录结构：

- Java为主Java代码文件夹

　 - Controller 控制器文件文件夹

　 - Dao （数据访问）层文件夹

　 - Service（业务逻辑）层文件夹

　 - Entity（实体）层文件 

- resources资源文件夹

　 - mapper mybatis文件夹

     - sql 数据表文件夹

- Test 测试文件夹

三、【maven包初始化】

Maven是采用配置文件的方式进行jar包的自动导入。下面添加我们将会用到的一系列jar包配置：

    4.0.0

    cn.com.springboot
    springboot_test
    0.0.1-SNAPSHOT
    jar
    springboot_test
    Demo project for Spring Boot

    
        org.springframework.boot
        spring-boot-starter-parent
        2.1.6.RELEASE
         
    

    
        UTF-8
        UTF-8
        1.8
    

    
        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            2.1.0
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        

        
            mysql
            mysql-connector-java
            8.0.13
        

        
            com.alibaba
            druid
            1.1.10
        

        
            com.fasterxml.jackson.core
            jackson-databind
            2.9.4
        
    

    
        
            
                org.apache.maven.plugins
                maven-compiler-plugin
                
                    1.8
                    1.8
                    utf-8
                
            
            
                org.springframework.boot
                spring-boot-maven-plugin
                
                    cn.com.springboot.SpringbootTestApplication
                
                
                    
                        
                            repackage
                        
                    
                
            
        
    

等待jar包下载到本地默认仓库，maven导入阶段完成，我们就可以进行下一步了。如果jar包不能正常导入，可以有下面处理办法：从这个地址：https://mvnrepository.com/；下载对应的jar包。然后查看本地是否安装了maven:

win+R快捷键，然后输入cmd，最后输入mvn -v；这里我已经配置好了，没有配置的自行百度。

通过命令安装jar包：

示例：mvn install:install-file -DgroupId=org.mybatis.generator -DartifactId=mybatis-generator-core -Dversion=1.3.5 -Dpackaging=jar -Dfile=D:\mybatis-generator-core-1.3.5.jar

-DgroupId、-DartifactId、 -Dversion可以参看我们pom里的jar包依赖修改，-Dfile是你下载下来的那个jar的本地目录，其他无需更改。

四、【springboot和mybatis配置】

配置文件包含：application.properties、logback-spring.xml、banner.txt

配置application.properties

mybatis.typeAliasesPackage=cn.com.springboot.entity
mybatis.mapperLocations=classpath:mapper/*.xml

# DataSouce
spring.datasource.url=jdbc:mysql://192.168.1.91:3306/test?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.max-wait=10000
spring.datasource.min-idle=2
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.maxActive=10
spring.datasource.initial-size=5
spring.datasource.validation-query=SELECT 1
spring.datasource.test-on-borrow=false
spring.datasource.test-while-idle=true
spring.datasource.time-between-eviction-runs-millis=18800
spring.datasource.filters=stat

配置logback-spring.xml

    
    
        
            %d{yyyy-MM-dd.HH:mm:ss.SSS} %t %p %c{0} %X{traceId} : %m%n
        
    

    
        
    

springboot在启动的时候有一个banner图，我们在这里可以实现自定义，banner.txt文件中存放的就是新的banner图。我们可以在线制作banner图，在线地址：http://patorjk.com/software/taag/#p=display&f=Henry%203D&t=spring%0A

我们创建的banner-springboot_test如下：

                               __                        _                            _                _                          _
    ____     _ ___     _ ___   LJ   _ ___      ___ _    FJ___      ____      ____    FJ_              FJ_      ____      ____    FJ_

           L_J                               J______F                                      L________J

五、【Demo构建】

打开数据库，执行以下脚本

CREATE TABLE `student` (
  `id` int(11) NOT NULL,
  `name` varchar(50) DEFAULT NULL,
  `age` int(11) DEFAULT NULL,
  `sex` int(11) DEFAULT NULL,
  `address` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO `test`.`student` (`id`, `name`, `age`, `sex`, `address`) VALUES ('1', '张三', '18', '1', '北京市朝阳区');
INSERT INTO `test`.`student` (`id`, `name`, `age`, `sex`, `address`) VALUES ('2', '王五', '20', '1', '天津市南开区');
INSERT INTO `test`.`student` (`id`, `name`, `age`, `sex`, `address`) VALUES ('3', '李丽', '22', '0', '上海市虹桥区');

下面我们从entity→mapper→dao→servive→SpringbootTestApplication来构建

编写entity：Student

package cn.com.springboot.entity;

public class Student {
    private int id;
    private String name;
    private int age;
    private int sex;
    private String address;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getSex() {
        return sex;
    }

    public void setSex(int sex) {
        this.sex = sex;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    @Override
    public String toString() {
        return "Student{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                ", sex=" + sex +
                ", address='" + address + '\'' +
                '}';
    }
}

编写mapper：UserMapper.xml

    
        
        
        
        
        
    

    
        
            t.id,
            t.name,
            t.age,
            t.sex,
            t.address
        
    
    
        SELECT
        
        FROM student t
    

编写dao：StudentDao

package cn.com.springboot.dao;

import cn.com.springboot.entity.Student;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface StudentDao {
    List listStudentInfo();
}

编写Service：StudentService

package cn.com.springboot.service;

public interface IStudentService {
    void datapush();
}

StudentServiceImpl

package cn.com.springboot.service.impl;

import cn.com.springboot.dao.StudentDao;
import cn.com.springboot.entity.Student;
import cn.com.springboot.service.IStudentService;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class StudentServiceImpl implements IStudentService {
    private static Logger logger = LoggerFactory.getLogger(StudentServiceImpl.class);
    @Autowired
    private StudentDao studentDao;

    @Override
    public void datapush() {
        logger.info("-------------学生信息数据推送任务开始执行-------------");
        List students = studentDao.listStudentInfo();
        ObjectMapper objectMapper = new ObjectMapper();
        String result = null;
        try {
            result = objectMapper.writerWithDefaultPrettyPrinter().writeValueAsString(students);
            logger.info("学生信息数据：\n" + result);
        } catch (JsonProcessingException e) {
            logger.error("数据转换异常[List to Json]", e);
        }

        // 模拟http post 推送数据到其它数据服务
        try {
            Thread.sleep(1000);
            logger.info("数据推送成功!");
        } catch (InterruptedException e) {
            logger.error("服务异常!", e);
        }
    }
}

编写SpringbootTestApplication

package cn.com.springboot;

import cn.com.springboot.service.IStudentService;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
@MapperScan("cn.com.springboot.dao")
public class SpringbootTestApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootTestApplication.class, args);
    }

    @Autowired
    private IStudentService studentService;

    @Bean
    public String starter(){
        studentService.datapush();
        return "success";
    }

}

完整目录如下：

至此，springboot-mybatis框架搭建完毕，如果想添加web进来，可以继续扩展。
