1.在pom檔案中新增maven依賴

<build>
        <finalName>lottery-common</finalName>
        <plugins>            
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.20.1</version>
                <configuration>
                    <skipTests>true</skipTests>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-source-plugin</artifactId>
                <version>2.2.1</version>
                <executions>
                    <execution>
                        <id>attach-sources</id>
                        <!--We are using the verify phase here because it is the phase that comes before the install phase, thus making sure that the sources jar has been created before the install takes place.-->
                        <phase>verify</phase>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-install-plugin</artifactId>
                <version>2.5.2</version>
            </plugin>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <!--配置檔案的位置-->
                    <configurationFile>src/main/resources/mybatis-generator/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <executions>
                    <execution>
                        <id>Generate MyBatis Artifacts</id>
                        <phase>deploy</phase><!--解決mvn package打包的時候執行了mybatis-generator-maven-plugin導致無法打包問題-->
                        <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>
        </plugins>
    </build>
 

2.建立generator.xml檔案

<?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>

    <!--匯入屬性配置-->
    <properties resource="mybatis-generator/generator.properties"></properties>

    <context id="context" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
            <property name="suppressDate" value="true"/>
        </commentGenerator>

        <!-- 資料庫的相關配置 -->
        <jdbcConnection
                driverClass="${jdbc.driverClass}"
                connectionURL="${jdbc.connectionURL}"
                userId="${jdbc.userId}"
                password="${jdbc.password}">
        </jdbcConnection>

        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!-- 實體類生成的位置 -->
        <javaModelGenerator targetPackage="com.zxm.mapper.dto.${jdbc.dataSourceName}" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- *Mapper.xml 檔案的位置 -->
        <sqlMapGenerator targetPackage="mapper.${jdbc.dataSourceName}" targetProject="src/main/resources">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- Mapper 介面檔案的位置 -->
        <javaClientGenerator targetPackage="com.zxm.mapper.dao.${jdbc.dataSourceName}" targetProject="src/main/java" type="XMLMAPPER">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>

        <!-- 相關表的配置 -->
        <table tableName="test" enableCountByExample="true" enableDeleteByExample="true" enableSelectByExample="true"
               enableUpdateByExample="false"/>
    </context>
</generatorConfiguration>
 

3.開啟MavenProject，點開Plugins，雙擊mybatis-generator：generate執行即可。
