## 1.首先创建webapp项目 在pom.xml中加入mybatis和junit的依赖 在build标签中加入mybatis.generator插件 ##

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <groupId>com.l</groupId>
        <artifactId>springMvc</artifactId>
        <packaging>pom</packaging>
        <version>1.0-SNAPSHOT</version>
        <name>springMvc Maven Webapp</name>
        <url>http://maven.apache.org</url>
        <properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <maven.build.timestamp.format>yyyyMMddHHmmss</maven.build.timestamp.format>
            <spring.version>4.3.12.RELEASE</spring.version>
            <mybatis.version>3.1.1</mybatis.version>
            <mybatisspring.version>1.1.1</mybatisspring.version>
        </properties>
        <dependencies>
    
            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>4.11</version>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>org.mybatis</groupId>
                <artifactId>mybatis</artifactId>
                <version>3.2.7</version>
            </dependency>
    
    
        </dependencies>
        <build>
            <finalName>springMvc</finalName>
            <plugins>
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>1.3.5</version>
                    <configuration>
                        
                        <verbose>true</verbose>
                        
                        <overwrite>true</overwrite>
                        <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </project>

## 2.然后在resource文件夹中新建generatorConfig.xml和相关目录 ##

并且创建好放置生成文件所需的包 dao文件放在com包下 mapper文件放在mapper包下 pojo放在pojo包

## 3.接下来配置生成配置 下面以mysql数据库作为例子 ##

<?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>
        
        <classPathEntry location="D:\迅雷下载\mybatis+mysql-connector-java-5.1.22-bin\mysql-connector-java-5.1.22-bin.jar"/>
        <context id="Mysql" targetRuntime="MyBatis3">
            <commentGenerator>
                <property name="suppressAllComments" value="true"/>
                <property name="suppressDate" value="true"/>
            </commentGenerator>
    
            
            <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost/test?useSSL=false" userId="root" password="1234"/>
    
            
            <javaModelGenerator targetPackage="com.l.pojo" targetProject="src/main/java">
                <property name="enableSubPackages" value="true"/>
            </javaModelGenerator>
    
            
            <sqlMapGenerator targetPackage="com.l.mapper" targetProject="src/main/java">
                <property name="enableSubPackages" value="true"/>
            </sqlMapGenerator>
    
            
            <javaClientGenerator type="XMLMAPPER" targetPackage="com.l.dao" targetProject="src/main/java">
                <property name="enableSubPackages" value="true"/>
            </javaClientGenerator>
    
            
            <table tableName="jincang" domainObjectName="jincang" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"/>
        </context>
    </generatorConfiguration>

## 4.生成文件，点击intellij右侧的mavenprojects，找到mybatisgenertor，右键run maven bulid，即可生成 ##

## 生成的xml文件会报错有大量的黄块，解决方法请看我博客的另外一篇文章 [http://blog.csdn.net/sinat\_29774479/article/details/78541874][http_blog.csdn.net_sinat_29774479_article_details_78541874] ##
