1.添加mybatis-generator插件，打開pom.xml文件 在project節點下添加：java

<build>
         <plugins>
         <!-- MyBatis代碼生成 -->
         <plugin>  
             <groupId>org.mybatis.generator</groupId>  
             <artifactId>mybatis-generator-maven-plugin</artifactId>  
             <version>1.3.2</version>  
             <configuration>  
                 <verbose>true</verbose>  
                 <overwrite>true</overwrite>  
                 <configurationFile>src_config/generatorConfig.xml</configurationFile>  
             </configuration>  
         </plugin> 
         </plugins>
         <resources>  
           <!-- 配置多個資源文件夾 -->
           <resource>  
              <directory>src_config</directory>  
           </resource>  
            </resources>  
     </build>

2.maven默認的資源文件是放在：src/main/resources下的，筆者習慣放在src_config下，因此上面使用了resources節點配置多個資源文件夾mysql

3.添加generatorConfig.properties文件，內容以下：web

#數據庫驅動jar  
drive.class.path=C:/Users/think/.m2/repository/mysql/mysql-connector-java/5.1.30/mysql-connector-java-5.1.30.jar
   
#數據庫鏈接參數  
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/trip?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=root
   
#包路徑配置  
model.package=com.trip.model
dao.package=com.trip.dao
xml.mapper.package=resources\mybatis\mappers
target.project=src/main/java

注意：mysql-connector-java-5.1.30.jar路徑 使用/ ，key-value後面不要有多餘的空格，不然會報找不到jdbc驅動。spring

4.添加generatorConfig.xml文件，內容以下：sql

<?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>  
<!-- 配置文件路徑 -->  
<properties resource="generatorConfig.properties"/>  
<!--數據庫驅動包路徑 -->  
<classPathEntry location="${drive.class.path}"/>  
   
<context id="MySQLTables" targetRuntime="MyBatis3">  
<!--關閉註釋 -->  
 <commentGenerator>  
<property name="suppressDate" value="true"/>  
</commentGenerator>  
   
<!--數據庫鏈接信息 -->  
<jdbcConnection driverClass="${jdbc.driver}" connectionURL="${jdbc.url}" userId="${jdbc.username}"  
password="${jdbc.password}">  
</jdbcConnection>  
   
<!--生成的model 包路徑 -->  
<javaModelGenerator targetPackage="${model.package}" targetProject="${target.project}">  
<property name="enableSubPackages" value="ture"/>  
<property name="trimStrings" value="true"/>  
</javaModelGenerator>  
   
<!--生成xml mapper文件 路徑 -->  
<sqlMapGenerator targetPackage="mybatis/mappers" targetProject="src_auth">  
<property name="enableSubPackages" value="ture"/>  
</sqlMapGenerator>  
   
<!-- 生成的Dao接口 的包路徑 -->  
<javaClientGenerator type="XMLMAPPER" targetPackage="${dao.package}" targetProject="${target.project}">  
<property name="enableSubPackages" value="ture"/>  
</javaClientGenerator>  
   
<!--對應數據庫表名 -->  
<table tableName="auth_user">  
   
</table>  
</context>  
</generatorConfiguration>

5.運行mybatis-generator插件數據庫

2.輸入命令：mybatis-generator:generateapache

3.生成成功json

筆者框架是基於SpringMVC+Mybatis，貼出pom.xml代碼mybatis
