mybatis-generator 自动生成代码

1.先上图

导入依赖

<!--mybatis逆向工程依赖-->
<dependency>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-core</artifactId>
    <version>1.3.7</version>
</dependency>

2.配置文件 generatorConfig.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 id="DB2Tables" targetRuntime="MyBatis3">
        <!-- 去除生成的注解 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!-- 数据库连接配置 -->
        <!-- 注意xml中不支持&，用&amp;代替  5.7:com.mysql.jdbc.Driver  8.0: com.mysql.cj.jdbc.Driver  -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3307/layui-ssm?useUnicode=true&amp;characterEncoding=utf8&amp;useSSL=false&amp;serverTimezone=GMT%2B8"
                        userId="root" password="123456"></jdbcConnection>

        <!-- 处理NUMERIC和DECIMAL类型的策略 -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- 配置pojo生成的位置 -->

            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!-- 配置sql映射文件的生成位置 -->
        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </sqlMapGenerator>

        <!-- 配置dao接口的生成位置 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.demo.dao"
                             targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaClientGenerator>

        <!-- 指定逆向依据的数据表 -->
        <!--数据库表-->
        <table tableName="admin" domainObjectName="Admin"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >
            <property name="useActualColumnNames" value="false"/>
        </table>
        <table tableName="book_info" domainObjectName="BookInfo"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >
            <property name="useActualColumnNames" value="false"/>
        </table>
        <table tableName="lend_list" domainObjectName="LendList"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >
            <property name="useActualColumnNames" value="false"/>
        </table>
        <table tableName="notice" domainObjectName="Notice"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >
            <property name="useActualColumnNames" value="false"/>
        </table>
        <table tableName="reader_info" domainObjectName="ReaderInfo"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >

            <property name="useActualColumnNames" value="false"/>
        </table>
    </context>
</generatorConfiguration>

创建执行类 GeneratorTest

package com.demo;

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

public class GeneratorTest {

    public static void main(String[] args) throws Exception {
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        File configFile = new File("D:/LearnProject/java/layui-ssm/src/main/resources/generatorConfig.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);
        System.out.println("生成成功！");
    }

}
