Mybatis逆工程jar包的修正和打包。本站提示廣大學習愛好者：（Mybatis逆工程jar包的修正和打包）文章只能為提供參考，不一定能成為您想要的結果。以下是Mybatis逆工程jar包的修正和打包正文
上一篇文章Mybatis逆工程的應用重要是講了mybatis-generator-core-1.3.2.jar的應用，這一篇我要引見的是，修正jar包代碼，完成生成自界說模板。
1.我們從這裡可以下載mybatis-generator-core-1.3.2.jar項目源碼
http://maven.outofmemory.cn/org.mybatis.generator/mybatis-generator-core/1.3.2/
2.在eclipse下導入存在的maven項目，File->Import
選擇項目源碼地位，點finish完成導入。
項目目次構造年夜概如許子。
3.上面我逆工程要生成的mapping和xml格局。
4.開端修正，起首解釋一下各目次
最底邊的tse包是我自界說的包，外面是個主類，測試生成的代碼能否到達預期尺度。
因為這個架包是老外寫的，生成的代碼作風和我們不年夜逐個樣，假如你想修正代碼格局，建議你看一下菠蘿年夜象的文章，我這裡就不講代碼格局了。
http://www.blogjava.net/bolo/archive/2015/03/20/423683.html
起首，我們先修正逆工程要生成的接口文件mapping的代碼，默許情形下有增刪改查，我們講個中一個改辦法update吧
好比 我要讓生成的mapping中有如許的一個辦法 void update(Map<String, Object> dataMap);
就修正org.mybatis.generator.codegen.mybatis3.javamapper.elements包下的UpdateByPrimaryKeyWithoutBLOBsMethodGenerator類，以下：

年夜家可以依據正文來修正。
接上去修正mapping對應的xml中的代碼，異樣的，這裡我只引見修正update辦法，信任看完你就可以本身修正其它辦法。
就修正org.mybatis.generator.codegen.mybatis3.xmlmapper.elements包下的UpdateByPrimaryKeyWithoutBLOBsElementGenerator類，以下：

其它辦法年夜家可以依據這個update辦法改。
假如要添加新辦法的話參考上面這個帖子
http://m.blog.csdn.net/article/details?id=35985705
上面我來驗證修正結果
generatorConfig.xml //先設置裝備擺設xml 放在src/main/resources/ 目次下 <?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> <!-- 引入設置裝備擺設文件 --> <!-- 指定命據銜接驅動jar地址 --> <classPathEntry location="E:\eclipse_workspace\testMybatis\mysql-connector-java-5.1.13-bin.jar" /> <!-- 一個數據庫一個context --> <context id="infoGuardian" targetRuntime="MyBatis3"> <!-- 正文 --> <commentGenerator > <property name="suppressAllComments" value="true"/><!-- 能否撤消正文 --> <property name="suppressDate" value="true" /> <!-- 能否生成正文代時光戳--> </commentGenerator> <!-- jdbc銜接 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/login?characterEncoding=UTF-8" userId="root" password="root" /> <!-- 類型轉換 --> <javaTypeResolver> <!-- 能否應用bigDecimal， false可主動轉化以下類型（Long, Integer, Short, etc.） --> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!-- 生成實體類地址 --> <javaModelGenerator targetPackage="pojo" targetProject="mybatis3" > <!-- 能否在以後途徑下新加一層schema,eg：fase途徑cn.ffcs.test.domain"， true:cn.ffcs.test.domain".[schemaName] --> <property name="enableSubPackages" value="true"/> <!-- 能否針對string類型的字段在set的時刻停止trim挪用 --> <property name="trimStrings" value="true"/> </javaModelGenerator> <!-- 生成mapxml文件 --> <sqlMapGenerator targetPackage="mapper" targetProject="mybatis3" > <!-- 能否在以後途徑下新加一層schema,eg：fase途徑cn.ffcs.test.domain"， true:cn.ffcs.test.domain".[schemaName] --> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <!-- 生成mapxml對應client，也就是接口dao --> <javaClientGenerator type="XMLMAPPER" targetPackage="mapper" targetProject="mybatis3"> <!-- 能否在以後途徑下新加一層schema,eg：fase途徑cn.ffcs.test.domain"， true:cn.ffcs.test.domain".[schemaName] --> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <!-- 設置裝備擺設表信息，這裡沒生成一張表，這裡須要轉變一次對應表名 --> <table tableName="login" domainObjectName="Login" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"> </table> </context> </generatorConfiguration>
StartUp.java//驗證的主法式
package tse;
import static org.junit.Assert.assertEquals;
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 StartUp {
public static void main(String []args)throws Exception{
List<String> warnings = new ArrayList<String>();
File configFile=new File(StartUp.class.getResource("/generatorConfig.xml").toURI());
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = cp.parseConfiguration(configFile);
DefaultShellCallback shellCallback = new DefaultShellCallback(true);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, shellCallback, warnings);
myBatisGenerator.generate(null);
System.out.println(warnings);
}
}
好了，運轉StartUp.java
就依據generatorConfig.xml的設置裝備擺設在目的目次生成對應文件。
OK，和我預期成果一樣。
5.下面修正完了，我們開端打包。
因為是個maven項目，我用的是maven3.3.9，年夜家也能夠用eclipse內置的maven，橫豎我是不愛好。
上面是我maven項目標pom.xml文件代碼

然後是修正src/main/assembly/src.xml代碼

</assembly>
接上去，在src/main/ 上面新建scripts文件夾,在scripts文件夾新建txt文本文檔，輸出以下代碼
java -jar mybatis-generator-1.3.2.jar -configfile generatorConfig.xml –overwrite
pause
改文件名為run.bat
至此，打包設置裝備擺設終了。
年夜家可以在項面前目今右鍵Run as->maven build 在goal裡輸出package。或許敕令行cmd中 進入項目標目次，運轉mvn package，這裡第一次運轉會期待良久，由於maven會下載依附的jar包，請耐煩期待。
打包終了，就會在項目根目次下的target目次生成以下構造
從上圖中我們可以看到mybatis-generator-core-1.3.2.jar包曾經生成。接上去我們可以用它加上generatorConfig.xml來生成本身想要的代碼。
假如修正代碼進程中有甚麼不懂的，請多看源代碼。
OK，曬下結果圖
本文就講到這裡！
以上所述是小編給年夜家引見的Mybatis逆工程jar包的修正和打包的相干常識，願望對年夜家有所贊助！
