springboot整合mybatis

springboot整合mybatis

springboot整合mybatis逆向生成插件
1.第一步导入相关的pom依赖

 <resources>
            <!--解决mybatis-generator-maven-plugin运行时没有将XxxMapper.xml文件放入target文件夹的问题-->
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <!--解决mybatis-generator-maven-plugin运行时没有将jdbc.properites文件放入target文件夹的问题-->
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>*.properties</include>
                    <include>*.xml</include>
                    <include>*.yml</include>
                </includes>
            </resource>
        </resources>

      <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <dependencies>
                    <!--使用Mybatis-generator插件不能使用太高版本的mysql驱动 -->
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>${mysql.version}</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>

2.导入逆向生成文件以及jdbc

3.在事物管理器里面配置字一行，整合mybatis就是这一行代码

4.写一个测试类测试一下查询以及删除的方法

Bookservice类

package com.zhoujun.springboot02.service;

import com.zhoujun.springboot02.entity.Book;

/**
 * @author 小俊
 * @company 流弊公司董事长
 * @create  2020-12-01 11:04
 */
public interface BookService {
    int deleteByPrimaryKey(Integer bid);

    Book selectByPrimaryKey(Integer bid);



}

Bookserviceimpl类

package com.zhoujun.springboot02.service.impl;

import com.zhoujun.springboot02.entity.Book;
import com.zhoujun.springboot02.mapper.BookMapper;
import com.zhoujun.springboot02.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * @author 小俊
 * @company 流弊公司董事长
 * @create  2020-12-01 11:05
 */
@Service
public class BookServiceImpl implements BookService {
    @Autowired
    private BookMapper bookMapper;
    @Override
    public int deleteByPrimaryKey(Integer bid) {
        return bookMapper.deleteByPrimaryKey(bid);
    }

    @Override
    public Book selectByPrimaryKey(Integer bid) {
        return bookMapper.selectByPrimaryKey(bid);
    }
}

测试

package com.zhoujun.springboot02.service.impl;
import com.zhoujun.springboot02.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.junit.jupiter.api.Test;
/**
 * @author 小俊
 * @company 流弊公司董事长
 * @create  2020-12-01 11:11
 */
@SpringBootTest
public class BookServiceImplTest  {
    @Autowired
    private BookService bookService;

    @Test
    public void deleteByPrimaryKey() {
        bookService.deleteByPrimaryKey(21);
    }

    @Test
    public void selectByPrimaryKey() {
        System.out.println(bookService.selectByPrimaryKey(28));
    }
}

测试结果
