声明：部分内容来自于

SpringBoot整合Mybatis（最全版）_lzh253985690的博客-CSDN博客

部分结合自身需要做出了修改

1.搭建项目环境

1.1新建项目

打开IDEA→File→New→Project

1.1新建项目

打开IDEA→File→New→Project

选择Maven→Next

填写组名、版本然后Next→Finish建好项目

1.2 引入依赖

打开pom.xml文件添加如下配置代码配置的作用已经在代码注释中写好

<?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">

    <artifactId>springboot-mybatis02</artifactId>
    <version>1.0-SNAPSHOT</version>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
    </parent>

    <!--指定编码为UTF-8 指定使用jdk1.8-->
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>

        <!-- -springboot 整合Web组件 整合SpringMVC 就会把传统方式的SpringMVC依赖的jar全部给下载来 -->
        <!-- 引入spring-boot-starter-web 帮你整合好所有相关的依赖jar包 原理 maven依赖传递 -->

            </plugin>
        </plugins>
    </build>



</project>

1.3 添加yml配置文件

在resources下新建配置文件application.yml

#端口号
server:
  port: 8889

#配置数据库
spring:
  datasource:
    username: hdev198
    password: Monjan123@
    url: jdbc:sybase:Tds:10.97.111.70:4100/db_qv?charset=big5hk
    driver-class-name: com.sybase.jdbc4.jdbc.SybDriver


mybatis:
  #mybatis的xml映射文件mapper存放路径
  mapper-locations: classpath:mapper/*Mapper.xml
  type-aliases-package: com.lzh.entity
  configuration:
    map-underscore-to-camel-case: true

#把sql语句打印在控制台
logging:
  level:
    com:
      example:
        mapper : debug

1.4 创建实体类实现业务流程

在java目录下创建如下包
com.lzh.controller、com.lzh.mapper、com.lzh.entity、com.lzh.service
在resources目录下创建mapper包

新建如下实体类直接复制粘贴代码即可

User.java

package com.lzh.entity;

public class User 
    private Long id;
    private String userName;
    private String passWord;

    public Long getId() 
        return id;
    

    public void setId(Long id) 
        this.id = id;
    

    public String getUserName() 
        return userName;
    

    public void setUserName(String userName) 
        this.userName = userName;
    

    public String getPassWord() 
        return passWord;
    

    public void setPassWord(String passWord) 
        this.passWord = passWord;
    

    @Override
    public String toString() 
        return "User" +
                "id=" + id +
                ", userName='" + userName + '\\'' +
                ", passWord='" + passWord + '\\'' +
                '';

UserMapper .java

package com.lzh.mapper;

import com.lzh.entity.User;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;

public interface UserMapper 
    @Select("SELECT * FROM db_test2 where id = #id")
    User getUserById1(@Param("id") Long id);

UserService .java

import org.springframework.stereotype.Service;

@Service
public class UserService 
    @Autowired
    UserMapper userMapper;

    public User getUserById1(Long id)
        User user = userMapper.getUserById1(id);
        return user;

UserController.java

package com.lzh.controller;

        import com.lzh.entity.User;
        import com.lzh.service.UserService;
        import org.springframework.beans.factory.annotation.Autowired;
        import org.springframework.web.bind.annotation.PathVariable;
        import org.springframework.web.bind.annotation.RequestMapping;
        import org.springframework.web.bind.annotation.RestController;

@RestController
public class UserController 

    @Autowired
    private UserService userService;

    @RequestMapping("/getUserById1/id")
    public User getUserById1(@PathVariable Long id) 
        User user = userService.getUserById1(id);
        return user;

1.5 添加启动类

在com.lzh包下创建类Application

package com.lzh;

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

@MapperScan("com.lzh.mapper") //mybatis扫描mapper的范围
@SpringBootApplication
public class Application 
    public static void main(String[] args) 
        SpringApplication.run(Application.class, args);

注意：

sybase的连接语句
   url: jdbc:sybase:Tds:10.97.111.70:4100/db_qv?charset=big5hk
   driver-class-name: com.sybase.jdbc4.jdbc.SybDriver


依赖为：
    <groupId>com.sybase</groupId>
            <artifactId>jconn4</artifactId>
            <version>1.0</version>
        </dependency>
