springBoot集成Mybatis-Generator

一、項目中創建Generator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>
    <context id="testTables" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自動生成的注釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!--數據庫連接的信息：驅動類、連接地址、用戶名、密碼 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://localhost:3306/me" userId="root"
            password="123456">
        </jdbcConnection>
        <!-- 默認false，把JDBC DECIMAL 和 NUMERIC 類型解析為 Integer，為 true時把JDBC DECIMAL 和 
            NUMERIC 類型解析為java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- targetProject:生成PO類的位置 -->
        <javaModelGenerator targetPackage="com.Interface.pojo"
            targetProject="src/main/java">
            <!-- enableSubPackages:是否讓schema作為包的后綴 -->
            <property name="enableSubPackages" value="false" />
            <!-- 從數據庫返回的值被清理前后的空格 -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- targetProject:mapper映射文件生成的位置 -->
        <sqlMapGenerator targetPackage="com.Interface.mapper" 
            targetProject="src/main/java">
            <!-- enableSubPackages:是否讓schema作為包的后綴 -->
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>
        <!-- targetPackage：mapper接口生成的位置 -->
        <javaClientGenerator type="XMLMAPPER"
            targetPackage="com.Interface.dao" 
            targetProject="src/main/java">
            <!-- enableSubPackages:是否讓schema作為包的后綴 -->
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
        <!-- 指定數據庫表 -->
        <table domainObjectName="ApplicationConfig" tableName="application_config" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
            <!-- 需要忽略的字段 -->
            <ignoreColumn column="backup1" delimitedColumnName=""/>
            <ignoreColumn column="backup2" delimitedColumnName=""/>
            <ignoreColumn column="backup3" delimitedColumnName=""/>
            <ignoreColumn column="backup4" delimitedColumnName=""/>
            <ignoreColumn column="backup5" delimitedColumnName=""/>
        </table>
    </context>
</generatorConfiguration>

二、pom.xml中添加插件

             <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <configurationFile>${basedir}/src/main/resources/Generator-config.xml</configurationFile>
                    <overwrite>true</overwrite>
                    <verbose>true</verbose>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>${mysql.version}</version>
                    </dependency>
                    <dependency>
                        <groupId>tk.mybatis</groupId>
                        <artifactId>mapper</artifactId>
                        <version>3.4.0</version>
                    </dependency>
                </dependencies>
            </plugin>

三、運行Maven build命令執行代碼生成
