SpringBoot+Mybatisg项目使用Generator自动生成代码

1.添加依赖—— 下

          <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.5</version>
                <dependencies>
                    <dependency>
                        <groupId> mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version> 5.1.39</version>
                    </dependency>
                    <dependency>
                        <groupId>org.mybatis.generator</groupId>
                        <artifactId>mybatis-generator-core</artifactId>
                        <version>1.3.5</version>
                    </dependency>
                </dependencies>
                <executions>
                    <execution>
                        <id>Generate MyBatis Artifacts</id>
                        <phase>package</phase>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <verbose>true</verbose>
                    <!-- 是否覆盖 -->
                    <overwrite>true</overwrite>
                    <!-- MybatisGenerator的配置文件位置 -->
                    <configurationFile>src/main/resources/mybatisGeneratorConfig.xml</configurationFile>
                </configuration>
            </plugin>

2. 创建配置文件mybatisGeneratorConfig.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="my-blog-generator-config" targetRuntime="MyBatis3">
        <!-- 生成的Java文件的编码 -->
        <property name="javaFileEncoding" value="utf-8"/>
        <!-- 格式化java代码 -->
        <property name="javaFormatter" value="org.mybatis.generator.api.dom.DefaultJavaFormatter"/>
        <!-- 格式化XML代码 -->
        <property name="xmlFormatter" value="org.mybatis.generator.api.dom.DefaultXmlFormatter"/>
        <plugin type="org.mybatis.generator.plugins.ToStringPlugin"/>
        <!--创建Java类时对注释进行控制-->
        <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>
        <!--数据库地址及登陆账号密码 改成你自己的配置-->
        <jdbcConnection
                driverClass="com.mysql.jdbc.Driver"
                connectionURL="jdbc:mysql://localhost:3306/my_blog_db"
                userId="root"
                password="root">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成实体类设置-->
        <javaModelGenerator targetPackage="com.imood.blog.entity" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!--生成Mapper文件设置-->
        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Mapper接口设置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.imood.blog.mapper"
                             targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!--需要自动生成代码的表及对应的类名设置-->
     
        <table tableName="你有表名" domainObjectName="类名（User）"
               enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
        </table>

    </context>
</generatorConfiguration>
