springboot配置逆向工程

如下所示：自動根據數據表生成對應的mapper.xml，實體類，dao層接口，service層需要手動寫。

1，引入逆向工程配置文件，在resources文件夾下新建generator，在引入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="test" targetRuntime="MyBatis3">
        <!-- 一些工具 -->
        <plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"></plugin>
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>

        <commentGenerator>
            <!-- 插入一個日期字段 -->
            <property name="suppressDate" value="true" />
            <!-- 注釋 -->
            <property name="suppressAllComments" value="false" />
        </commentGenerator>
        <!--數據庫鏈接 參數 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/test1" userId="root"
                        password="root">
        </jdbcConnection>
        <javaTypeResolver>
            <!-- This property is used to specify whether MyBatis Generator should
                force the use of java.math.BigDecimal for DECIMAL and NUMERIC fields, -->
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!-- 生成模型的包名和位置 -->
        <javaModelGenerator targetPackage="com.demo.entity"
                            targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- 生成映射文件的包名和位置 -->
        <sqlMapGenerator targetPackage="resources/mapper"
                         targetProject="src/main">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <!-- 生成DAO的包名和位置 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.demo.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <!-- 要生成哪些表 -->

        <!-- 表
            tableName:表名
            domainObjectName:要生成的文件名
        -->
        <!--<table tableName="employee" domainObjectName="Employee"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
        <table tableName="role" domainObjectName="Role"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
        <table tableName="resc" domainObjectName="Resc"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>-->
        <table tableName="orderForm" domainObjectName="OrderForm"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
    </context>
</generatorConfiguration>

2，pom.xml導入逆向工程包

<!-- mybatis逆向工程jar包 -->
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.2</version>
        </dependency>

3，在plugins標簽里添加逆向工程maven工具

            <!-- mybatis 逆向工程maven工具， -->
            <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>5.1.38</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <!--配置文件的路徑 -->
                    <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>

4，點擊idea右邊的maven project，找到圖中圈中的，右鍵啟動，控制出現success 就成功了

 

 

 

 

創建成功。。

 

 

 

 

 

 

<----------------------------------------------------分割線----------------------------------------------------------------------------------->

springboot中mapper.xml文件是放在resources下的

 

 

 

這個是我demo里pom文件中所有的
