Maven集成插件mybatis-generator(mybatis自动生成实体代码的插件)

1.在pom.xml中配置

<build>
        <plugins>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>${mysql.version}</version>
                    </dependency>
                    <dependency>
                        <groupId>tk.mybatis</groupId>
                        <artifactId>mapper</artifactId>
                        <version>${mapper.version}</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <!--配置文件的路径-->
                    <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>
        </plugins>
    </build>

2.在/src/main/resources/ 目录下写generatorConfig.xml

<?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">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <!-- 通用mapper插件 -->
        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="tk.mybatis.mapper.common.Mapper"/>
        </plugin>

        <!-- 注释 -->
        <commentGenerator>
            <property name="suppressTypeWarnings" value="true"/><!-- 抑制警告 -->
            <property name="suppressAllComments" value="true"/><!-- 是否取消注释 -->
            <property name="suppressDate" value="true"/><!-- 是否生成注释代时间戳-->
        </commentGenerator>

        <!-- 代码生成统一放到test包下，以免直接覆盖原有的代码造成不可挽回的损失。 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/liuren?useUnicode=true&characterEncoding=UTF-8"
                        userId="root" password="123"/>

        <javaModelGenerator targetPackage="com.liuren.api.domain"
                            targetProject="MAVEN">
            <property name="enableSubPackages" value="true"/>
            <!-- 是否针对string类型的字段在set的时候进行trim调用 -->
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="/resources/mybatis/mapper"
                         targetProject="MAVEN">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>

        <javaClientGenerator type="XMLMAPPER" targetPackage="com.liuren.service.dao"
                             targetProject="MAVEN">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <table tableName="t_user" domainObjectName="UserDO"
               enableSelectByExample="false"
               enableDeleteByExample="false"
               enableCountByExample="false"
               enableUpdateByExample="false">
            <generatedKey column="id" sqlStatement="Mysql" identity="true"/>
        </table>
    </context>
</generatorConfiguration>

注：注意修改数据库连接的用户名，密码，url，已经各种生成文件的存放路径。

最后双击红色区域即可生成。
