Recently, because of the project needs, research the use of MyBatis 3.x, of course, by the way also studied the use of generator to reverse engineering to generate pojo,mapper and other documents. Before using this tool, download the relevant jar package, I am using the latest Mybatis-generator-core-1.3.2.jar.
Generatorconfig.xml is listed below:
<?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= "Context1" > <jdbcconnection driverclass= "Com.mysql.jdbc.Driver" connectionurl= "Jdbc:mysql://localhost:3306/test?useunicode=true&characterencoding=utf8" userid= "Root" Password= "" /> <javamodelgenerator targetpackage= "Com.lanx.test.domain" targetproject= "/home/user/workspace/mybatis-web/src/main/java" /> < Sqlmapgenerator targetpackage= "Com.lanx.test.mapper" targetproject= "/home/user/workspace/mybatis-web/src/main/resources/" /> < Javaclientgenerator targetpackage= "Com.lanx.test.mapper" type= "Xmlmapper" targetproject= "/home/ User/workspace/mybatis-web/src/main/java " /> <table Domainobjectname= ' person ' tablename= ' person ' enablecountbyexample= ' false ' enabledeletebyexample= "false" Enableselectbyexample= "false" enableupdatebyexample= "false" > <property name= "Modelonly" value= "false"/> </table> </context></generatorConfiguration>
I placed the XML file under the project root, followed by a similar official document:
Http://generator.sturgeon.mopaas.com/running/runningFromCmdLine.html
Run MyBatis Generator from the command line
As stated in the documentation, execute:
java -jar /home/user/backup/mybatis-generator-core-1.3.2.jar -configfile Generatorconfig.xml The following error occurred:exception in thread "main" java.lang.RuntimeException: exception getting jdbc driver at Org.mybatis.generator.internal.db.ConnectionFactory.getDriver (connectionfactory.java:85) at org.mybatis.generator.internal.db.connectionfactory.getconnection ( CONNECTIONFACTORY.JAVA:54) at Org.mybatis.generator.config.Context.getConnection (context.java:526) at org.mybatis.generator.config.context.introspecttables (context.java:436) at org.mybatis.generator.api.mybatisgenerator.generate (MyBatisGenerator.java:222) at org.mybatis.generator.apI.shellrunner.main (shellrunner.java:117) caused by: java.lang.classnotfoundexception: Com.mysql.jdbc.driver at java.net.urlclassloader$1.run ( urlclassloader.java:372) at java.net.urlclassloader$1.run ( urlclassloader.java:361) at Java.security.AccessController.doPrivileged (Native method) at java.net.urlclassloader.findclass (urlclassloader.java:360) at java.lang.classloader.loadclass (classloader.java:424) at sun.misc.launcher$appclassloader.loadclass (launcher.java:308) at java.lang.classloader.loadclass (classloader.java:357) &NBSP;&NBSP;&NBSP;&NBSP;AT&NBSP;JAVA.LANG.CLASS.FORNAME0 (Native&nbsP Method) at java.lang.class.forname (Class.java:344) at Org.mybatis.generator.internal.ObjectFactory.internalClassForName (objectfactory.java:150) at org.mybatis.generator.internal.objectfactory.externalclassforname ( objectfactory.java:121) at Org.mybatis.generator.internal.db.ConnectionFactory.getDriver (connectionfactory.java:82) ... 5 more
In fact, it has been estimated before running, obviously did not introduce the MySQL driver jar package, the modified statement is as follows:
Java-cp/home/user/backup/mybatis-generator-core-1.3.2.jar:/home/user/backup/mysql-connector-java-5.1.36.jar Org.mybatis.generator.api.shellrunner-configfile Generatorconfig.xml
After running, successfully generated files such as Pojo, pay attention to Generatorconfig.xml file Javamodelgenerator and so on several nodes Targetproject attribute configuration, here I have written absolute path. In fact, if there is an error in this configuration, a warning prompt appears when you write a nonexistent folder.
While using Java programs to run MyBatis Generator 1.3.x, copy the code given on this website directly.
The reference URL is as follows: http://generator.sturgeon.mopaas.com/running/runningWithJava.html
Finally, my development environment: Ubuntu Kylin + ECLIPSE-LUNA-SR2 + jdk8
Run MyBatis Generator 1.3.x from the command line and Java program to generate mybatis3.x code
