使用mybatis-gen生成sql

一、config.properties文件

#数据库连接
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=gbk
jdbc.user=root
jdbc.password=1234

# 生成模型的包名
target.model.package=test.entity
target.sql.package=test.mapping
target.client.package=test.dao

# 生成文件要放置路径
target.model.project=src
target.sql.project=src
target.client.project=src

二、config.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>
    <properties resource="config.properties" />
    <classPathEntry location="mysql-connector-java-5.1.26.jar" />

    <context id="DB" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/> 
              
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <jdbcConnection driverClass="${jdbc.driver}"
            connectionURL="${jdbc.url}" userId="${jdbc.user}" password="${jdbc.password}">
        </jdbcConnection>

        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <javaModelGenerator targetPackage="${target.model.package}"
            targetProject="${target.model.project}">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <sqlMapGenerator targetPackage="${target.sql.package}"
            targetProject="${target.sql.project}">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <javaClientGenerator type="XMLMAPPER" 
            targetPackage="${target.client.package}" 
            targetProject="${target.client.project}">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        <!-- add your table below -->
    <table tableName="t_external_bank_card_replace_log" domainObjectName="ExternalBankCardReplaceLog"/>
    
    </context>
</generatorConfiguration>

三、gen.bat

@ECHO OFF
del /f /s /q .\src
md .\src
java -cp .;mybatis-generator-core-1.3.2.jar org.mybatis.generator.api.ShellRunner -configfile config.xml -overwrite
pause
@ECHO ON

四、下载jar包

mybatis-generator-core-1.3.2.jar

mysql-connector-java-5.1.26.jar

五、执行gen.bat，即可
