1.配置pom.xml

给pom.xml加Mybatis的plugin：

<project ...>
    
       ...
       
        <build>
    	...
    	
            <plugins>
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <configuration>
                        <verbose>true</verbose>
                        <overwrite>true</overwrite>
                    </configuration>
                </plugin>
            </plugins>
    
          ...
        </build>
    
         ...
    
    </project>

2.配置generatorConfig.xml    
  
        生成的xml存放在src\\main\\resources路径下

<?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>
        
        <context id="MysqlTables" targetRuntime="MyBatis3">
            <property name="autoDelimitKeywords" value="true"/>
            <property name="javaFileEncoding" value="UTF-8"/>
            <property name="beginningDelimiter" value="`"/>
            <property name="endingDelimiter" value="`"/>
            <commentGenerator>
                <property name="suppressDate" value="true"/>
                
                <property name="suppressAllComments" value="false"/>
            </commentGenerator>
            
            <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                            connectionURL=""
                            userId="" password=""/>
            <javaTypeResolver>
                <property name="forceBigDecimals" value="false"/>
            </javaTypeResolver>
            
            <javaModelGenerator targetPackage="com.daka.core.po"
                                targetProject="../daka-core/src/main/java">
                <property name="enableSubPackages" value="true"/>
                <property name="trimStrings" value="true"/>
    
            </javaModelGenerator>
            
            <sqlMapGenerator targetPackage="mapper"
                             targetProject="../daka-core/src/main/resources">
                <property name="enableSubPackages" value="true"/>
    
            </sqlMapGenerator>
            
            <javaClientGenerator type="ANNOTATEDMAPPER"
                                 targetPackage="com.daka.core.pojo"
                                 targetProject="../daka-core/src/main/java">
                <property name="enableSubPackages" value="true"/>
            </javaClientGenerator>
            
            <table tableName="a_admin_role" enableCountByExample="false" enableUpdateByExample="false"
                   enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
                <property name="useActualColumnNames" value="true"/>
            </table>
    
            <table tableName="a_admin_user" enableCountByExample="false" enableUpdateByExample="false"
                   enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
                <property name="useActualColumnNames" value="true"/>
                <generatedKey column="adminId" sqlStatement="MySql" identity="true"/>
            </table>
    
        </context>
    </generatorConfiguration>

3.执行maven命令   
  
        mvn mybatis-generator:generate   
       生成Mybatis文件
