mybatis generator 代码自动生成

1.准备好mysql连接jar包

2.编写generator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>
    <!--location里填写mysql-connector-java jar包的位置-->
    <classPathEntry
            location="D:\mvn-repository\mysql\mysql-connector-java\5.1.46\mysql-connector-java-5.1.46.jar"/>
    <context id="mysql" targetRuntime="MyBatis3">
        <!--为关键字自动加上引号-->
        <property name="autoDelimitKeywords" value="true"/>
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>
        <!--覆盖生成的XML-->
        <!--<plugin type="org.mybatis.generator.plugins.UnmergeableXmlMappersPlugin" />-->
        <commentGenerator>
            <property name="suppressDate" value="false"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <!--数据库连接参数-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/coolwind"
                        userId="root"
                        password="123456"/>

        <!--生成的entity存放的位置-->
        <javaModelGenerator targetPackage="cn.coolwind.bootshiro.web.entity"
                            targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!--生成的mapper.XML存放的位置-->
        <sqlMapGenerator targetPackage="mapper"
                         targetProject="src/main/resources/">
            <property name="enableSubPackages" value="true"/>

        </sqlMapGenerator>

        <!--生成的mapper存放的位置-->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="cn.coolwind.bootshiro.web.mapper"
                             targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!--生成的表名-->
        <table tableName="test" domainObjectName="Test" enableCountByExample="false"
               enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>

    </context>
</generatorConfiguration>

3.在项目的pom里，加入插件

<!--mybatis自动生成插件-->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <configurationFile>src/main/resources/generator/generatorConfig.xml</configurationFile>
                    <overwrite>true</overwrite>
                    <verbose>true</verbose>
                </configuration>
                <executions>
                    <execution>
                        <id>Generator Mybatis Artifact</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>

注意：

这里的位置必须与前面编写的配置文件存放的位置一致

4.运行maven的generator插件

生成完毕：
