Spring boot中的mybatis逆向工程

1.在resource報下創建generatorConfig.xml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>
			<!-- 是否去除自動生成的註釋 true：是 ： false:否 -->
			<property name="suppressAllComments" value="true" />
		</commentGenerator>
		<!--數據庫連接的信息：驅動類、連接地址、用戶名、密碼 -->
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://xxx:3306/xxxx?useUnicode=true&amp;characterEncoding=UTF-8&amp;useSSL=false" userId="xxx"
			password="xxxx">
		</jdbcConnection>
		<!-- 默認false，把JDBC DECIMAL 和 NUMERIC 類型解析爲 Integer，爲 true時把JDBC DECIMAL 和 
			NUMERIC 類型解析爲java.math.BigDecimal -->
		<javaTypeResolver>
			<property name="forceBigDecimals" value="false" />
		</javaTypeResolver>

		<!-- targetProject:生成PO類的位置 -->
		<javaModelGenerator targetPackage="com.edu.zzti.bean"
			targetProject=".\src">
			<!-- enableSubPackages:是否讓schema作爲包的後綴 -->
			<property name="enableSubPackages" value="false" />
			<!-- 從數據庫返回的值被清理前後的空格 -->
			<property name="trimStrings" value="true" />
		</javaModelGenerator>
        <!-- targetProject:mapper映射文件生成的位置 -->
		<sqlMapGenerator targetPackage="com.edu.zzti.mapper"
			targetProject=".\src">
			<!-- enableSubPackages:是否讓schema作爲包的後綴 -->
			<property name="enableSubPackages" value="false" />
		</sqlMapGenerator>
		<!-- targetPackage：mapper接口生成的位置 -->
		<javaClientGenerator type="XMLMAPPER"
			targetPackage="com.edu.zzti.mapper"
			targetProject=".\src">
			<!-- enableSubPackages:是否讓schema作爲包的後綴 -->
			<property name="enableSubPackages" value="false" />
		</javaClientGenerator>
		<!-- 指定數據庫表 -->
		<table tableName="user"></table>
		<table tableName="orders"></table>
		<table tableName="goods"></table>
		<table tableName="comment"></table>
		<table tableName="merchant"></table>
		<table tableName="type"></table>
		<table tableName="address"></table>
		<table tableName="shoppingcart"></table>
		<!-- <table schema="" tableName="sys_user"></table>
		<table schema="" tableName="sys_role"></table>
		<table schema="" tableName="sys_permission"></table>
		<table schema="" tableName="sys_user_role"></table>
		<table schema="" tableName="sys_role_permission"></table> -->
		<!-- 有些表的字段需要指定java類型
		 <table schema="" tableName="">
			<columnOverride column="" javaType="" />
		</table> -->
	</context>
</generatorConfiguration>

2.導入依賴

<!--mybatis工程逆向依賴-->
    <dependency>
      <groupId>org.mybatis.generator</groupId>
      <artifactId>mybatis-generator-core</artifactId>
      <version>1.3.7</version>
    </dependency>

3.逆向工程生成類

package com.edu.zzti;

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 MyGenerator {
	public void generate() throws Exception{
		List<String> warnings = new ArrayList<String>();
		boolean overwrite = true;
		//指定逆向工程配置文件
		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);
	}

	public static void main(String []args) throws Exception {
		try {
			MyGenerator myGenerator = new MyGenerator();
			myGenerator.generate();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
