三步使用mybatisGengerator生成dao层代码

1.引入依赖

<!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core -->
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.5</version>
        </dependency>

2.编写配置文件

<?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="DB2Tables" targetRuntime="MyBatis3">
        <!--配置数据库连接信息-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://127.0.0.1:3306/ssm?useUnicode=true&amp;characterEncoding=utf-8"
                        userId="root"
                        password="000000">
        </jdbcConnection>

        <javaTypeResolver >
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!--指定JavaBean生成的位置-->
        <javaModelGenerator
                targetPackage="com.hzy.beans"
                targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--指定mapper文件生成的位置-->
        <sqlMapGenerator
                targetPackage="mapper"
                targetProject=".\src\main\resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <!--指定dao接口生成位置-->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.hzy.dao"
                             targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <!--指定每个表的生成策略-->
        <table tableName="user" domainObjectName="User"/>
        <table tableName="myorder" domainObjectName="Order"/>

    </context>
</generatorConfiguration>

3.运行

List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        File configFile = new File("./src/main/resources/generator.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);
