使用maven进行mybatis逆向工程

1. 添加maven插件，让maven环境支持mybatis-generator组件
   在pom.xml里面添加如下代码：

<build>
        <finalName>taotao</finalName>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>1.3.2</version>
                    <configuration>
                        <configurationFile>src/main/resources/generator.xml</configurationFile>
                        <verbose>true</verbose>
                        <overwrite>true</overwrite>
                    </configuration>
                    <executions>
                        <execution>
                            <id>Generate MyBatis Artifacts</id>
                            <goals>
                                <goal>generate</goal>
                            </goals>
                        </execution>
                    </executions>
                    <dependencies>
                        <dependency>
                            <groupId>org.mybatis.generator</groupId>
                            <artifactId>mybatis-generator-core</artifactId>
                            <version>1.3.2</version>
                        </dependency>
                    </dependencies>
                </plugin>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>2.19.1</version>
                    <configuration>
                        <skipTests>true</skipTests>
                    </configuration>
                </plugin>

                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-resources-plugin</artifactId>
                    <version>3.0.1</version>
                    <configuration>
                        <encoding>UTF-8</encoding>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>

2. 在pom.xml，添加数据库依赖

 <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.35</version>
            <scope>runtime</scope>
        </dependency>

3. 新建generator.xml配置文件

<?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>  
    <!-- 数据库驱动包位置 -->  
    <classPathEntry    
        location="E:\apache-maven-3.3.9\repo\mysql\mysql-connector-java\5.1.18\mysql-connector-java-5.1.18.jar" />    
    <context id="Tables" targetRuntime="MyBatis3">  
        <commentGenerator>  
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->  
            <property name="suppressAllComments" value="true" />  
        </commentGenerator>  
        <!-- 数据库链接URL、用户名、密码 -->  
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"  
            connectionURL="jdbc:mysql://192.168.100.52:3306/dev_test" userId="数据库用户名"  
            password="数据库密码">  
            <!--<jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@localhost:1521:orcl"   
                userId="msa" password="msa"> -->  
        </jdbcConnection>  
        <javaTypeResolver>  
            <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer， 为 true时把JDBC DECIMAL和NUMERIC类型解析为java.math.BigDecimal -->  
            <property name="forceBigDecimals" value="true" />  
        </javaTypeResolver>  
        <!-- 生成实体类的包名和位置，这里配置将生成的实体类放在com.loan.test.entity这个包下 -->  
        <javaModelGenerator targetPackage="com.loan.test.entity"  
            targetProject=".\src\main\java\">  
            <!-- enableSubPackages:是否让schema作为包的后缀 -->  
            <property name="enableSubPackages" value="true" />  
            <!-- 从数据库返回的值被清理前后的空格 -->  
            <property name="trimStrings" value="true" />  
        </javaModelGenerator>  
        <!-- 生成的SQL映射文件包名和位置，这里配置将生成的SQL映射文件放在com.loan.test.dao.xml这个包下 -->  
        <sqlMapGenerator targetPackage="com.loan.test.dao.xml"  
            targetProject=".\src\main\java\">  
            <!-- enableSubPackages:是否让schema作为包的后缀 -->  
            <property name="enableSubPackages" value="true" />  
        </sqlMapGenerator>  
        <!-- 生成DAO的包名和位置，这里配置将生成的dao类放在com.loan.test.dao.mapper这个包下 -->  
        <javaClientGenerator type="XMLMAPPER"  
            targetPackage="com.loan.test.dao.mapper" targetProject=".\src\main\java\">  
            <!-- enableSubPackages:是否让schema作为包的后缀 -->  
            <property name="enableSubPackages" value="true" />  
        </javaClientGenerator>  
        <!-- 要生成那些表(更改tableName和domainObjectName就可以) -->  
        <table tableName="test" domainObjectName="Test"  
            enableCountByExample="false" enableUpdateByExample="false"  
            enableDeleteByExample="false" enableSelectByExample="false"  
            selectByExampleQueryId="false" />  
    </context>  
</generatorConfiguration>  

4. 运用maven指令生成逆向工程
   项目右键->run as->maven build...,Goals:中输入mybatis-generator:generate

   
   如图

5. 刷新项目。
