springboot和mybatis下逆向生成实体类和.xml映射文件

导入jar包和插件

 我的idea版本必须导入jar包依赖，有的可以直接导入插件

  <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.5</version>
        </dependency>


  <!--添加mybatis generator maven插件-->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.5</version>
                <configuration>
                    <!--generatorConfig.xml位置-->
                    <configurationFile>src/main/resources/mybatis-generator/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <executions>
                    <execution>
                        <id>Generate MyBatis Artifacts</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                        <phase>generate-sources</phase>
                    </execution>
                </executions>

                <!--此处必须添加oracle驱动包-->
                <dependencies>
                    <dependency>
                        <groupId>com.oracle</groupId>
                        <artifactId>ojdbc6</artifactId>
                        <version>11.1.0.6.0</version>
                        <scope>system</scope>
                        <systemPath>${basedir}/src/main/resources/lib/ojdbc6-11.1.0.6.0.jar</systemPath>
                    </dependency>
                </dependencies>
            </plugin>

创建generatorConfig.xml文件

在resources下创建mybatis-generator

<?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">
<!-- 第二种mybatis逆向生成xml配置 -->
<generatorConfiguration>
    <!-- 需要指明数据库连接器的绝对路径 -->
    <classPathEntry
            location="C:\Users\Administrator\Desktop\connection-sql\ojdbc6-11.1.0.6.0.jar" />
    <context id="sqlserverTables" targetRuntime="MyBatis3">
        <!-- 生成的pojo，将implements Serializable-->
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>
        <commentGenerator>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>

        <!-- 数据库链接URL、用户名、密码 -->
        <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver"
                        connectionURL="jdbc:oracle:thin:@localhost:1521/orcl"
                        userId="jtf"
                        password="123456">
        </jdbcConnection>

        <!--
        默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer
            true，把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal
        -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!--
        生成model模型，对应的包路径，以及文件存放路径(targetProject)，targetProject可以指定具体的路径,如./src/main/java，
        也可以使用“MAVEN”来自动生成，这样生成的代码会在target/generatord-source目录下
        -->
        <!--<javaModelGenerator targetPackage="com.joey.mybaties.test.pojo" targetProject="MAVEN">-->
        <javaModelGenerator targetPackage="com.teng.springbootshiro.domain" targetProject="./src/main/java">
            <property name="enableSubPackages" value="true"/>
            <!-- 从数据库返回的值被清理前后的空格  -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--对应的mapper.xml文件  -->
        <sqlMapGenerator targetPackage="com.teng.springbootshiro.mapper" targetProject="./src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>

        <!-- 对应的Mapper接口类文件 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.teng.springbootshiro.mapper" targetProject="./src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>


        <!-- 列出要生成代码的所有表，这里配置的是不生成Example文件 -->
        <table tableName="sys_user" domainObjectName="SysUser"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >
            <property name="useActualColumnNames" value="false"/>
        </table>

        <table tableName="sys_permission" domainObjectName="SysPermission"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >
            <property name="useActualColumnNames" value="false"/>
        </table>

        <table tableName="sys_role" domainObjectName="SysRole"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >
            <property name="useActualColumnNames" value="false"/>
        </table>

        <table tableName="sys_role_permission" domainObjectName="SysRolePermission"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >
            <property name="useActualColumnNames" value="false"/>
        </table>

        <table tableName="sys_user_role" domainObjectName="SysUserRole"
               enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" selectByExampleQueryId="false" >
            <property name="useActualColumnNames" value="false"/>
        </table>
    </context>
</generatorConfiguration>

生成实体类和mapper.xml

点击MavernProject

双击mybatis-generator:generate

成功！
