ibator自动代码生成

首先，强烈推荐一篇文章，介绍的特详细

http://www.iteye.com/topic/821983

1. 插件安装

http://blog.csdn.net/rchm8519/article/details/40792821

2. 创建项目，导入ibator-2.0.jar

略。。。。

3. 创建ibator描述文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE ibatorConfiguration PUBLIC "-//Apache Software Foundation//DTD Apache iBATIS Ibator Configuration 1.0//EN" "http://ibatis.apache.org/dtd/ibator-config_1_0.dtd" >

    <!-- 指定数据库驱动jar包路径;注意:该属性不在默认配置文件中，需要手动添加，建议使用绝对路径-->
    <classPathEntry location="D:\javaTools\ojdbc14.jar" />

    <!--
        id:使用命令行运行Abator时指定，以单独处理某一个ibatorContext
        targetRuntime:Ibatis2Java5 生成适合JDK5.0的类，另一个选项是 Ibatis2Java2，生成适合Java2的类。
    -->
    <ibatorContext  id="FlatJava5" targetRuntime="Ibatis2Java5">
        <property name="suppressTypeWarnings" value="true" />

        </table>
    </ibatorContext>
</ibatorConfiguration>

4. 添加ibator插件java类

ibatorConfig.xml中使用了自定义插件org.apache.ibatis.ibator.plugins.PackageRefactorPlugin

源码如下：

package org.apache.ibatis.ibator.plugins;

import java.util.List;

import org.apache.ibatis.ibator.api.FullyQualifiedTable;
import org.apache.ibatis.ibator.api.IbatorPluginAdapter;
import org.apache.ibatis.ibator.api.IntrospectedTable;
import org.apache.ibatis.ibator.api.dom.xml.XmlElement;
import org.apache.ibatis.ibator.config.TableConfiguration;

public class PackageRefactorPlugin extends IbatorPluginAdapter{

    @Override
    public boolean validate(List<String> warnings) {
        // TODO Auto-generated method stub
        return true;
    }

    @Override
    public void initialized(IntrospectedTable introspectedTable) { 

       TableConfiguration tableConfig =  introspectedTable.getTableConfiguration();
       String pack = getPackage(tableConfig);
       calculateDAOAttributes(pack,introspectedTable);
       calculateModelAttributes(pack,introspectedTable);
       calculateXmlAttributes(pack,introspectedTable);
    }

    protected void calculateXmlAttributes(String pakkage,IntrospectedTable introspectedTable){
        introspectedTable.setIbatis2SqlMapPackage(pakkage);
        String sqlmap = introspectedTable.getFullyQualifiedTable().getDomainObjectName().replaceAll("EO", "")+".xml";
        introspectedTable.setIbatis2SqlMapFileName(sqlmap);
    }

    protected void calculateDAOAttributes(String pakkage,IntrospectedTable introspectedTable) {
        FullyQualifiedTable fullyQualifiedTable = introspectedTable.getFullyQualifiedTable();
        StringBuilder sb = new StringBuilder();
        sb.append(pakkage);
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName().replaceAll("EO", ""));
        sb.append("DAOImpl"); //$NON-NLS-1$
        introspectedTable.setDAOImplementationType(sb.toString());
        sb.setLength(0);
        sb.append(pakkage);
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName().replaceAll("EO", ""));
        sb.append("DAO"); //$NON-NLS-1$
        introspectedTable.setDAOInterfaceType(sb.toString());
    }

    protected void calculateModelAttributes(String pakkage,IntrospectedTable introspectedTable) {
        FullyQualifiedTable fullyQualifiedTable = introspectedTable.getFullyQualifiedTable();
        StringBuilder sb = new StringBuilder();
        sb.append(pakkage);
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName());
        sb.append("Key"); //$NON-NLS-1$
        introspectedTable.setPrimaryKeyType(sb.toString());

        sb.setLength(0);
        sb.append(pakkage);
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName());
        introspectedTable.setBaseRecordType(sb.toString());

        sb.setLength(0);
        sb.append(pakkage);
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName().replaceAll("EO", ""));
        sb.append("WithBLOBs"); //$NON-NLS-1$
        introspectedTable.setRecordWithBLOBsType(sb.toString());

        sb.setLength(0);
        sb.append(pakkage);
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName().replaceAll("EO", ""));
        sb.append("Example"); //$NON-NLS-1$
        introspectedTable.setExampleType(sb.toString());
    }

    public String getPackage(TableConfiguration tableConfig){
        String basePack = "com.sdo.mas.common.database";
        String pack = tableConfig.getProperty("package");
        if( null  != pack && "".equals(pack) == false){
            return pack;
        }else{
            pack = tableConfig.getTableName().toLowerCase().replaceAll("_", "");
        }
        pack =  basePack +"."+pack;
        return pack;
    }

    @Override
    public boolean sqlMapInsertElementGenerated(XmlElement element, IntrospectedTable introspectedTable) {
        return true;

    }

    @Override
    public boolean sqlMapUpdateByExampleSelectiveElementGenerated(XmlElement element,
            IntrospectedTable introspectedTable) {
        return true;
    }

    @Override
    public boolean sqlMapUpdateByExampleWithBLOBsElementGenerated(XmlElement element,
            IntrospectedTable introspectedTable) {
      //  AbstractXmlElementGenerator generator = new UpdateByExampleWithBLOBsElementGenerator();
      //  generator.setIntrospectedTable(introspectedTable);
      //  generator.setIbatorContext(ibatorContext);
    //    generator.addElements(element);
        return true;
    }

    @Override
    public boolean sqlMapUpdateByExampleWithoutBLOBsElementGenerated(XmlElement element,
            IntrospectedTable introspectedTable) {
     //   AbstractXmlElementGenerator generator = new UpdateByExampleWithoutBLOBsElementGenerator();
     //   generator.setIntrospectedTable(introspectedTable);
    //    generator.setIbatorContext(ibatorContext);
      //  generator.addElements(element);
        return true;
    }

    @Override
    public boolean sqlMapUpdateByPrimaryKeySelectiveElementGenerated(XmlElement element,
            IntrospectedTable introspectedTable) {
     //   AbstractXmlElementGenerator generator = new UpdateByPrimaryKeySelectiveElementGenerator();
     //   generator.setIntrospectedTable(introspectedTable);
    //    generator.setIbatorContext(ibatorContext);
    //    generator.addElements(element);
        return true;
    }

    @Override
    public boolean sqlMapUpdateByPrimaryKeyWithBLOBsElementGenerated(XmlElement element,
            IntrospectedTable introspectedTable) {
    //    AbstractXmlElementGenerator generator = new UpdateByPrimaryKeyWithBLOBsElementGenerator();
   //     generator.setIntrospectedTable(introspectedTable);
   //     generator.setIbatorContext(ibatorContext);
   //     generator.addElements(element);
        return true;
    }

    @Override
    public boolean sqlMapUpdateByPrimaryKeyWithoutBLOBsElementGenerated(XmlElement element,
            IntrospectedTable introspectedTable) {
    //    AbstractXmlElementGenerator generator = new UpdateByPrimaryKeyWithoutBLOBsElementGenerator();
      //  generator.setIntrospectedTable(introspectedTable);
     //   generator.setIbatorContext(ibatorContext);
    //    generator.addElements(element);
        return true;
    }

    @Override
    public boolean sqlMapInsertSelectiveElementGenerated(XmlElement element, IntrospectedTable introspectedTable) {
    //    AbstractXmlElementGenerator generator = new InsertSelectiveElementGenerator();
   //     generator.setIntrospectedTable(introspectedTable);
   //     generator.setIbatorContext(ibatorContext);
   //     generator.addElements(element);
        return true;
    }

}

5. 生成代码

　　java类如下，直接执行它就行

package com.li.test.util;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import org.apache.ibatis.ibator.api.Ibator;
import org.apache.ibatis.ibator.config.IbatorConfiguration;
import org.apache.ibatis.ibator.config.xml.IbatorConfigurationParser;
import org.apache.ibatis.ibator.internal.DefaultShellCallback;

public class IbatorRunTest {

    public static void main(String[] args) {
        try {
            List<String> warnings = new ArrayList<String>();
            boolean overwrite = true;
            String file = IbatorRunTest.class.getClassLoader().getResource("ibatorConfig.xml").getFile();
            File configFile = new File(file);
            IbatorConfigurationParser cp = new IbatorConfigurationParser(warnings);
            IbatorConfiguration config = cp.parseIbatorConfiguration(configFile);
            DefaultShellCallback callback = new DefaultShellCallback(overwrite);
            Ibator ibator = new Ibator(config, callback, warnings);
            ibator.generate(null);
            for (String warning : warnings) {
                System.out.println("warning:" + warning);
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }

    }

}

6. 使用说明
