一、Springboot 结合 Mybatis-generator

1，修改Pom文件添加Maven引用，添加完成在idea右侧可看到mybatis-generator:generate插件。

<build>
        <plugins>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.7</version>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>8.0.16</version>
                    </dependency>
                </dependencies>
                <executions>
                    <execution>
                        <id>Generate MyBatis Artifacts</id>
                        <phase>package</phase>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <!--允许移动生成的文件 -->
                    <verbose>true</verbose>
                    <!-- 是否覆盖 -->
                    <overwrite>false</overwrite>
                    <!-- 自动生成的配置 -->
                    <configurationFile>src/main/resources/mybatis-generater.xml</configurationFile>
                </configuration>
            </plugin>
        </plugins>
    </build>

2，在resources添加文件mybatis-generater.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" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--数据库连接 -->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://172.16.2.100:3306/my_dubbo_db?serverTimezone=UTC"
                        userId="root"
                        password="root">
            <property name="useInformationSchema" value="true"/>
        </jdbcConnection>

        <!-- 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 -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="true" />
        </javaTypeResolver>

        <javaModelGenerator targetPackage="com.study.wzf.myuserprovider.dal.entity"
                            targetProject="src/main/java">
            <!-- 是否允许子包，即targetPackage.schemaName.tableName -->
            <property name="enableSubPackages" value="true"/>
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="com.study.wzf.myuserprovider.dal.persistence" targetProject="src/main/java"/>

        <javaClientGenerator targetPackage="com.study.wzf.myuserprovider.dal.persistence"
                             targetProject="src/main/java"
                             type="XMLMAPPER"/>
        <!--已生成的表
         <table tableName="tb_payment" domainObjectName="Payment"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
        -->
        <table tableName="wzf_member" domainObjectName="WfMember"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
        <table tableName="wzf_member_address" domainObjectName="WfMemberAddress"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>


    </context>
</generatorConfiguration>

3，双击mybatis-generator:generate，即可生成对应的代码。

 

二，Spring结合 Mybatis-generator

1，其他不变，添加maven插件，添加配置文件mybatis-generater.xml

2，修改配置文件，这样可以更灵活的生成代码，如下:

 <!--导入属性配置-->
<properties resource="application-test.properties"/>

  <!--数据库连接 -->
<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
        connectionURL="${jdbc.url}"
        userId="${jdbc.username}"
        password="${jdbc.password}">
        <property name="useInformationSchema" value="true"/>
</jdbcConnection>

3，双击mybatis-generator:generate运行，即可生成对应的代码。
