**mybatis自动代码生成工具maven插件可以帮助我们轻松的生成pojo、dao、mapper.xml文件，相比于mybatis-generator等其他方式方便许多，话不多说，上代码**

先看一下整体操作图

**一、引入maven依赖**

<dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <optional>true</optional>
            </dependency>
    
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <scope>runtime</scope>
            </dependency>
    
            <dependency>
                <groupId>org.mybatis.spring.boot</groupId>
                <artifactId>mybatis-spring-boot-starter</artifactId>
                <version>RELEASE</version>
            </dependency>
    
        </dependencies>
    
        
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
    
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>1.3.2</version>
                    <configuration>
                        
                        <configurationFile>src/main/resources/mybatis-generator-config.xml</configurationFile>
                        <verbose>true</verbose>
                        <overwrite>false</overwrite>
                    </configuration>
                    <executions>
                        <execution>
                            <id>Generate MyBatis Artifacts</id>
                            <goals>
                                <goal>generate</goal>
                            </goals>
                        </execution>
                    </executions>
                    <dependencies>
                        <dependency>
                            <groupId>org.mybatis.generator</groupId>
                            <artifactId>mybatis-generator-core</artifactId>
                            <version>1.3.2</version>
                        </dependency>
                    </dependencies>
                </plugin>
            </plugins>
        </build>

**二 、将mybatis-generator-config.xml放在src/main/resources目录下即可**

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE generatorConfiguration
            PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
            "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
    
    <generatorConfiguration>
        <classPathEntry
                location="D:\mavenLocalRepository\mysql\mysql-connector-java\5.1.45\mysql-connector-java-5.1.45.jar"/>
        <context id="prod" targetRuntime="MyBatis3">
            <commentGenerator>
                
                <property name="suppressAllComments" value="true"/>
            </commentGenerator>
    
            
            <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                            connectionURL="jdbc:mysql://172.25.62.81:3306/micro_mall" userId="root"
                            password="123456">
            </jdbcConnection>
            
            <javaTypeResolver>
                <property name="forceBigDecimals" value="false"/>
            </javaTypeResolver>
    
            
            <javaModelGenerator targetPackage="com.gdz.mybatisgenerator.pojo"
                                targetProject="src\main\java">
                
                <property name="enableSubPackages" value="false"/>
                
                <property name="trimStrings" value="true"/>
            </javaModelGenerator>
            
            <sqlMapGenerator targetPackage="mapper"
                             targetProject="src\main\resources">
                
                <property name="enableSubPackages" value="false"/>
            </sqlMapGenerator>
            
            <javaClientGenerator type="XMLMAPPER"
                                 targetPackage="com.gdz.mybatisgenerator.mapper"
                                 targetProject="src\main\java">
                
                <property name="enableSubPackages" value="false"/>
            </javaClientGenerator>
    
            <table alias="" schema="" tableName="hotel_info"></table>
            
        </context>
    </generatorConfiguration>

修改成自己的mysql连接jar的地址、数据库地址、pojo dao mapper.xml包名以及需要操作的数据表

**三、运行mybatis-generator:generate插件即可**

**注意：**

**   1、将maven pom文件中的<overwrite>false</overwrite>这个位置改为false之后，**

**       每次运行都会生成数字结尾的文件，利用idea的compare files来增量更新即可。**
