mybatis-generator的使用
只需要三步,即可把数据库里面的表,生成实体类
1、pom.xml
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.4.0</version>
<configuration>
<configurationFile>src/main/resources/generator/generator-config.xml</configurationFile>
<overwrite>true</overwrite>
<verbose>true</verbose>
</configuration>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.22</version>
</dependency>
</dependencies>
</plugin>
2、generator-config.xml(放在resources/generator下面)
<?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="Mysql" targetRuntime="MyBatis3" defaultModelType="flat">
<!-- 自动检查关键字,为关键字增加反引号 -->
<property name="autoDelimitKeywords" value="true"/>
<property name="beginningDelimiter" value="`"/>
<property name="endingDelimiter" value="`"/>
<!--覆盖生成XML文件-->
<plugin type="org.mybatis.generator.plugins.UnmergeableXmlMappersPlugin" />
<!-- 生成的实体类添加toString()方法 -->
<plugin type="org.mybatis.generator.plugins.ToStringPlugin"/>
<!-- 不生成注释 -->
<commentGenerator>
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/wiki?serverTimezone=UTC"
userId="wiki"
password="wiki">
</jdbcConnection>
<!-- pojo类的位置 -->
<javaModelGenerator targetProject="src\main\java"
targetPackage="com.yishuai.wiki.pojo"/>
<!-- mapper xml的位置 -->
<sqlMapGenerator targetProject="src\main\resources"
targetPackage="mapper"/>
<!-- mapper类的位置 -->
<javaClientGenerator targetProject="src\main\java"
targetPackage="com.yishuai.wiki.mapper"
type="XMLMAPPER"/>
<!--<table tableName="demo" domainObjectName="Demo"/>-->
<table tableName="ebook"/>
<!--<table tableName="category"/>-->
<!--<table tableName="doc"/>-->
<!--<table tableName="content"/>-->
<!--<table tableName="user"/>-->
<!-- <table tableName="ebook_snapshot"/>-->
</context>
</generatorConfiguration>
3、新增启动项
