创建逆向工程的两种模板

第一种方式:运用逆向工程的配件
a>先把pom.xml的依赖加载上(springboot-rz19\resource)
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.itqf</groupId>
    <artifactId>mybatis-generator</artifactId>
    <version>1.0-SNAPSHOT</version>

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

    <build>
        <plugins>
            <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>5.1.45</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <!--配置文件的路径-->
                    <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>
b>然后把generatorConfig.xml配置资源放在resource中,别忘记修改里面的数据库及里面的要逆向生成的表名
<?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>
        <!--<plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin>-->
        <commentGenerator>
            <!-- 是否去除自动生成的注释 true:是 : false:否 -->
            <property name="suppressAllComments" value="false" />
        </commentGenerator>
        <!--数据库链接 参数 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/shiroboot" userId="root"
                        password="admin">
        </jdbcConnection>
        <javaTypeResolver>
            <!-- This property is used to specify whether MyBatis Generator should
                force the use of java.math.BigDecimal for DECIMAL and NUMERIC fields, -->
            <!-- 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 -->
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!-- 生成模型的包名和位置 -->
        <javaModelGenerator targetPackage="com.itqf.dtboot.entity"
                            targetProject="src/main/java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <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>
        <!-- 生成映射文件的包名和位置 -->
        <sqlMapGenerator targetPackage="com.itqf.dtboot.dao"
                         targetProject="src/main/resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <!-- 生成DAO的包名和位置 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.itqf.dtboot.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <!-- 要生成哪些表 -->
        <table tableName="sys_menu" domainObjectName="SysMenu"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false"></table>
        <table tableName="sys_role" domainObjectName="SysRole"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false"></table>
       
    </context>
</generatorConfiguration>

c>运行打开maven projects找到下面鼠标点击的地方右键run maven build记住只能点击一次


第二中方式:不用pom.xml的方式:直接把generatorCongfig.xml放在resources中,代码在上面
a>写一个测试类
public class Testgenerator {
    
    public static void main(String[] args) throws Exception {
        
        List<String> warnings = new ArrayList<String>();
           boolean overwrite = true;
           File configFile = new File("src/main/resources/generatorConfig.xml");
           ConfigurationParser cp = new ConfigurationParser(warnings);
           Configuration config = cp.parseConfiguration(configFile);
           DefaultShellCallback callback = new DefaultShellCallback(overwrite);
           MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
           myBatisGenerator.generate(null);
        
           System.out.println("success");
        
    }

b>直接运行上面的代码即可

注意:如果要反复使用,一定要把之前生成的代码全部删除干净
