1.创建generatorSqlmapCustom工程
2.修改pom文件
<?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"> <parent> <artifactId>xmall-parent</artifactId> <groupId>com.huawei</groupId> <version>1.0-SNAPSHOT</version> <relativePath>../xmall-parent/pom.xml</relativePath> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>generatorSqlmapCustom</artifactId> <name>generatorSqlmapCustom</name> <!-- FIXME change it to the project's website --> <url>http://www.example.com</url> <dependencies> <dependency> <artifactId>xmall-common</artifactId> <groupId>com.huawei</groupId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.5</version> </dependency> </dependencies> <build> <finalName>mybatis_generator</finalName> <plugins> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.5</version> <dependencies> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.5</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.32</version> </dependency> </dependencies> </plugin> </plugins> </build> </project>
3.添加官方提供的逆向工程源码
package com.huawei.manager; import java.io.File; import java.util.ArrayList; import java.util.List; import org.mybatis.generator.api.MyBatisGenerator; import org.mybatis.generator.config.Configuration; import org.mybatis.generator.config.xml.ConfigurationParser; import org.mybatis.generator.internal.DefaultShellCallback; public class GeneratorSqlmap { public void generator() throws Exception{ List<String> warnings = new ArrayList<>(); boolean overwrite = true; //指定 逆向工程配置文件 File configFile = new File("classpath: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); } public static void main(String[] args) throws Exception { try { GeneratorSqlmap generatorSqlmap = new GeneratorSqlmap(); generatorSqlmap.generator(); } catch (Exception e) { e.printStackTrace(); } } }
4.添加并修改配置文件
<?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> <!-- 是否去除自动生成的注释 true：是 ： false:否 --> <property name="suppressAllComments" value="true" /> </commentGenerator> <!--数据库连接的信息：驱动类、连接地址、用户名、密码 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.81.130:3306/xmall" userId="root" password="root"> </jdbcConnection> <!-- 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 --> <javaTypeResolver> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- targetProject:生成PO类的位置 --> <javaModelGenerator targetPackage="com.huawei.manager.pojo" targetProject="./src/main/java"> <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="false" /> <!-- 从数据库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.huawei.manager.mapper" targetProject="./src/main/java"> <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="false" /> </sqlMapGenerator> <!-- targetPackage：mapper接口生成的位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.huawei.manager.mapper" targetProject="./src/main/java"> <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="false" /> </javaClientGenerator> <!-- 指定数据库表 --> <table schema="" tableName="tb_panel"></table> <table schema="" tableName="tb_panel_content"></table> <table schema="" tableName="tb_item"></table> <table schema="" tableName="tb_item_cat"></table> <table schema="" tableName="tb_item_desc"></table> <table schema="" tableName="tb_item_param"></table> <table schema="" tableName="tb_item_param_item"></table> <table schema="" tableName="tb_order"></table> <table schema="" tableName="tb_order_item"></table> <table schema="" tableName="tb_order_shipping"></table> <table schema="" tableName="tb_user"></table> <table schema="" tableName="tb_member"></table> <table schema="" tableName="tb_address"></table> <table schema="" tableName="tb_role"></table> <table schema="" tableName="tb_permission"></table> <table schema="" tableName="tb_role_perm"></table> <table schema="" tableName="tb_thanks"></table> <table schema="" tableName="tb_shiro_filter"></table> <table schema="" tableName="tb_base"></table> <table schema="" tableName="tb_log"></table> <table schema="" tableName="tb_express"></table> <table schema="" tableName="tb_dict"></table> </context> </generatorConfiguration>
log4j的配置文件
log4j.rootLogger=DEBUG, Console #Console log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.layout=org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n log4j.logger.java.sql.ResultSet=DEBUG log4j.logger.org.apache=DEBUG log4j.logger.java.sql.Connection=DEBUG log4j.logger.java.sql.Statement=DEBUG log4j.logger.java.sql.PreparedStatement=DEBUG
5.添加完成后的目录结构如下：
6.运行maven工程，生成代码
7.生成后的代码结构如下：
一只小飞机
