一、配置逆向generatoe.xml

<?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 targetRuntime='MyBatis3'> <!-- 是否生成注釋 --> <commentGenerator> <property name='suppressAllComments' value='true' /> </commentGenerator> <!-- 配置數據庫連接信息 --> <jdbcConnection driverClass='com.mysql.jdbc.Driver' connectionURL='jdbc:mysql://localhost:3306/ssm_crud?serverTimezone=UTC' userId='root' password='root'> <!--<property name='useInformationSchema' value='true'/>--> </jdbcConnection> <javaTypeResolver > <property name='forceBigDecimals' value='false' /> </javaTypeResolver> <!-- 指定javaBean生成的位置 --> <javaModelGenerator targetPackage='com.atguigu.crud.bean' targetProject='.srcmainjava'> <property name='enableSubPackages' value='true' /> <property name='trimStrings' value='true' /> </javaModelGenerator> <!-- 指定sql映射文件生成的位置 --> <sqlMapGenerator targetPackage='mapper' targetProject='.srcmainresources'> <property name='enableSubPackages' value='true' /> </sqlMapGenerator> <!-- 指定dao接口生成位置，mapper接口 --> <javaClientGenerator type='XMLMAPPER' targetPackage='com.atguigu.crud.dao' targetProject='.srcmainjava'> <property name='enableSubPackages' value='true' /> </javaClientGenerator> <!-- table指定每個表的生成策略 --> <table tableName='tbl_emp' domainObjectName='Employee' /> <table tableName='tbl_dept' domainObjectName='Department' /> </context></generatorConfiguration>

二、執行生成代碼

public class MBGTest { public static void main(String[] args) throws Exception{ List<String> warnings = new ArrayList<String>(); boolean overwrite = true; File configFile = new File('mbg.xml'); ConfigurationParser cp = new ConfigurationParser(warnings); Configuration config = cp.parseConfiguration(configFile); DefaultShellCallback callback = new DefaultShellCallback(overwrite); MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings); myBatisGenerator.generate(null); }}

三、結果mapper中未能生成...ByPrimaryKey的方法

四、解決辦法

在generatoe.xml的配置數據庫連接信息時，添加

<property name='useInformationSchema' value='true'/>

即可解決問題
