mybatis-generator工具

目录

简介

mybatis框架中，自动生成model，dao和mapper的工具。很大程度上减少了业务开发人员的手动编码时间，一下为使用方法。

使用方法

1.配置pom.xml

			<!--添加依赖-->
			<dependency>
				<groupId>org.mybatis.generator</groupId>
				<artifactId>mybatis-generator-core</artifactId>
				<version>1.3.2</version>
			</dependency>


			<!--plugin中添加-->
			<plugin>
				<!--Mybatis-generator插件,用于自动生成Mapper和POJO-->
				<groupId>org.mybatis.generator</groupId>
				<artifactId>mybatis-generator-maven-plugin</artifactId>
				<version>1.3.2</version>
				<configuration>
					<!--配置文件的位置-->
					<configurationFile>src/main/resources/mybatis/mybatis-generator.xml</configurationFile>
					<verbose>true</verbose>
					<overwrite>true</overwrite>
				</configuration>
				<executions>
					<execution>
						<id>Generate MyBatis Artifacts</id>
						<goals>
							<goal>generate</goal>
						</goals>
					</execution>
				</executions>
			</plugin>

2.在resource下新建mybatis-generator.xml（路径与pom.xml中配置相同）

<?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>
    <!--数据库驱动-->
    <classPathEntry    location="C:\Users\2009210077\.m2\repository\mysql\mysql-connector-java\8.0.11\mysql-connector-java-8.0.11.jar"/>
    <context id="context"    targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--数据库链接地址账号密码-->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/mysql?serverTimezone=UTC" userId="root" password="root">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成Model类存放位置-->
        <javaModelGenerator targetPackage="com.example.demo.model" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!--生成映射文件存放位置-->
        <sqlMapGenerator targetPackage="mybatis.mapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Dao类存放位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.example.demo.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!--生成对应表及类名-->
        <table tableName="book" domainObjectName="bookDAO" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

3.运行

Idea中，点击右侧栏Maven，在Plugins中找到mybatis-generator:generate，双击运行。
