4：generatorConfig.xml自动生成model层，dao层，xml  mapper文件配置。（重点）

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

        </table>
    </context>
</generatorConfiguration>

5：操作generatorConfig.xml自动生成model层，dao层，xml  mapper

5：Emp实体类

package com.example.demo.model;

import java.util.Date;

public class Emp {
    private Integer EMPNO;

    private String ENAME;

    private String JOB;

    private Double MGR;

    private Date HIREDATE;

    private Double SAL;

    private Double COMM;

    private Integer DEPTNO;

    public Integer getEMPNO() {
        return EMPNO;
    }

    public void setEMPNO(Integer EMPNO) {
        this.EMPNO = EMPNO;
    }

    public String getENAME() {
        return ENAME;
    }

    public void setENAME(String ENAME) {
        this.ENAME = ENAME;
    }

    public String getJOB() {
        return JOB;
    }

    public void setJOB(String JOB) {
        this.JOB = JOB;
    }

    public Double getMGR() {
        return MGR;
    }

    public void setMGR(Double MGR) {
        this.MGR = MGR;
    }

    public Date getHIREDATE() {
        return HIREDATE;
    }

    public void setHIREDATE(Date HIREDATE) {
        this.HIREDATE = HIREDATE;
    }

    public Double getSAL() {
        return SAL;
    }

    public void setSAL(Double SAL) {
        this.SAL = SAL;
    }

    public Double getCOMM() {
        return COMM;
    }

    public void setCOMM(Double COMM) {
        this.COMM = COMM;
    }

    public Integer getDEPTNO() {
        return DEPTNO;
    }

    public void setDEPTNO(Integer DEPTNO) {
        this.DEPTNO = DEPTNO;
    }
}

6：EmpMapper类

package com.example.demo.dao;

import com.example.demo.model.Emp;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface EmpMapper {
    int deleteByPrimaryKey(Integer EMPNO);

    int insert(Emp record);

    int insertSelective(Emp record);

    Emp selectByPrimaryKey(Integer EMPNO);

    int updateByPrimaryKeySelective(Emp record);

    int updateByPrimaryKey(Emp record);

}

7：EmpService类

public interface EmpService {

    public Emp getEmpById(Integer empno);

}

8：EmpServiceImpl类

package com.example.demo.service.impl;

import com.example.demo.dao.EmpMapper;
import com.example.demo.model.Emp;
import com.example.demo.service.EmpService;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service
public class EmpServiceImpl implements EmpService {

    @Autowired
    EmpMapper empMapper;
    @Override
    public Emp getEmpById(Integer empno) {
        return empMapper.selectByPrimaryKey(empno);
    }
}

9：EmpController类

package com.example.demo.controller;

import com.example.demo.model.Emp;


import com.example.demo.service.EmpService;
import com.example.demo.service.impl.EmpServiceImpl;
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.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("/emp")
public class EmpController {
    @Autowired
    EmpService empService;
    @RequestMapping(value = "/empInfo",method= RequestMethod.GET)
    public Emp getEmpInfo(@RequestParam(value ="empno",required = true) Integer empno){
        return  empService.getEmpById(empno);
    }

}

10：启动类DemoApplication

package com.example.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@EnableTransactionManagement   //开启事务管理
@MapperScan("com.example.demo.dao")//扫码dao层
@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {

        SpringApplication.run(DemoApplication.class, args);

    }

}

11：application.yml配置文件

#配置tomcat端口以及tomcat编码
server:
    port: 8555
    tomcat:
        uri-encoding: UTF-8
#配置连接mysql数据库
spring:
    datasource:
        username: root
        password:

        url: jdbc:mysql://localhost:3306/empcore?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
#配置扫码Mapper.xml文件
mybatis:
    mapper-locations: classpath:mappers/*Mapper.xml
    type-aliases-package: com.example.demo.model
#扫码日志配置文件（如果暂时不想使用日志可以不用添加）
logging:
    level:
        com.example.demo.dao: debug
    config: classpath:logback-spring.xml

12：logback-spring.xml配置日志文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="60 seconds" debug="false">
    <contextName>logback </contextName>
    <!--指定日志存储位置-->
    <property name="log.path" value="D:\\myDemo\\log\\logback.log" />
    <!--输出到控制台-->
    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <!-- <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
        <level>ERROR</level>
        </filter>-->
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n </pattern>
        </encoder>
    </appender>

    <!--输出到文件-->
    <appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${log.path}</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>logback.%d{yyyy-MM-dd}.log </fileNamePattern>
            <maxHistory>30 </maxHistory>
            <totalSizeCap>1GB </totalSizeCap>
        </rollingPolicy>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n </pattern>
        </encoder>
    </appender>




    <root level="info">
        <appender-ref ref="console" />
        <appender-ref ref="file" />
    </root>
    <!-- logback为java中的包 -->
    <logger name="com.dudu.controller"/>
    <!--logback.LogbackDemo：类的全路径 -->
    <logger name="com.dudu.controller.LearnController" level="WARN" additivity="false">
        <appender-ref ref="console"/>
    </logger>
</configuration>

13：项目启动成功

14：访问项目接口
