HIbernate-tools修改记录

HIbernate-tools修改记录
1，增加中文注释，参考BLOG:http://www.blogjava.net/pauliz/archive/2009/11/13/302162.html
2，修改默认ID生成规则

public String getTableIdentifierStrategyName(TableIdentifier identifier) {
		//return "assigned";
		return "uuid";//默认UUID
	}

3，增加ONE-TO-MANY的集合注解的targetEntity属性，也可以增加其他属性

public String generateCollectionAnnotation(Property property, Configuration cfg) {
		StringBuffer annotation = new StringBuffer();
		Value value = property.getValue();
		if ( value != null && value instanceof Collection) {
			Collection collection = (Collection) value;
			if ( collection.isOneToMany() ) {
				String mappedBy = null;
				OneToMany oneToMany = (OneToMany) collection.getElement();
				annotation.append("    @").append( importType( "javax.persistence.OneToMany") )
						.append( "(cascade={").append(getCascadeType( property ) ).append("}")
						//melon add FIXME 增加targetEntity属性
						//.append(",targetEntity=").append(getTargetClassName(property)).append(".class")
						.append(",targetEntity=").append(oneToMany.getReferencedEntityName()).append(".class")
						.append(", fetch=").append( getFetchType( property ) );
				if ( collection.isInverse() ) {
					annotation.append(", mappedBy=\"");
					mappedBy = getOneToManyMappedBy( cfg, collection );
					annotation.append( mappedBy ).append("\"");
				}
				annotation.append(")");
				if (mappedBy == null) annotation.append("\n").append( generateJoinColumnsAnnotation(property) );
			}
			else {
				//TODO do the @OneToMany @JoinTable
				//TODO composite element
				String mappedBy = null;
				annotation.append("    @").append( importType( "javax.persistence.ManyToMany") )
						.append( "(cascade={").append(getCascadeType( property ) ).append("}")
						.append(", fetch=").append( getFetchType( property ) );
				if ( collection.isInverse() ) {
					annotation.append(", mappedBy=\"");
					mappedBy = getManyToManyMappedBy( cfg, collection );
					annotation.append( mappedBy ).append("\"");
				}
				annotation.append(")");
				if (mappedBy == null) {
					annotation.append("\n    @");
					annotation.append( importType( "javax.persistence.JoinTable") ).append( "(name=\"" );
					Table table = collection.getCollectionTable();
					
					annotation.append( table.getName() );
					annotation.append( "\"" );
					if ( StringHelper.isNotEmpty( table.getSchema() ) ) {
						annotation.append(", schema=\"").append( table.getSchema() ).append("\"");
					}
					if ( StringHelper.isNotEmpty( table.getCatalog() ) ) {
						annotation.append(", catalog=\"").append( table.getCatalog() ).append("\"");
					}
					String uniqueConstraint = generateAnnTableUniqueConstraint(table);
					if ( uniqueConstraint.length() > 0 ) {
						annotation.append(", uniqueConstraints={").append(uniqueConstraint).append("}");
					}
					annotation.append( ", joinColumns = { ");
					buildArrayOfJoinColumnAnnotation(
							collection.getKey().getColumnIterator(),
							annotation,
							property.isInsertable(),
							property.isUpdateable()
					);
					annotation.append( " }");
					annotation.append( ", inverseJoinColumns = { ");
					buildArrayOfJoinColumnAnnotation(
							collection.getElement().getColumnIterator(),
							annotation,
							property.isInsertable(),
							property.isUpdateable()
					);
					annotation.append( " }");
					annotation.append(")");
				}

			}
			String hibernateCascade = getHibernateCascadeTypeAnnotation( property );
			if (hibernateCascade.length() > 0) annotation.append("\n    ").append(hibernateCascade);
		}
		return annotation.toString();
	}

4,通过hibernate.cfg.xml配置自动生成带注解的JAVA domain文件

import java.io.File;
import java.util.Properties;

import junit.framework.TestCase;

import org.hibernate.cfg.Configuration;
import org.hibernate.cfg.JDBCMetaDataConfiguration;
import org.hibernate.cfg.reveng.DefaultReverseEngineeringStrategy;
import org.hibernate.cfg.reveng.ReverseEngineeringSettings;
import org.hibernate.tool.hbm2x.POJOExporter;

public class GeneratePojoTest extends TestCase {

	public void testGenerateJava() {
		
			Configuration xmlcfg = new Configuration().configure("/hibernate.cfg.xml");
			
			JDBCMetaDataConfiguration cfg = new JDBCMetaDataConfiguration();
			Properties properties = xmlcfg.getProperties();
			cfg.setProperties(properties);
			
			DefaultReverseEngineeringStrategy configurableNamingStrategy = new DefaultReverseEngineeringStrategy();
			configurableNamingStrategy.setSettings(new ReverseEngineeringSettings()
					.setDefaultPackageName("net.esj.test.generic")//要生成的包名
					.setCreateCollectionForForeignKey(true)//是否生成many-to-one的在one端的集合类
					.setCreateManyToOneForForeignKey(true)//是否生成many-to-one
					.setDetectManyToMany(true)//是否生成many-to-many
					.setDetectOptimisticLock(true) //乐观锁对象？
					);
			cfg.setReverseEngineeringStrategy(configurableNamingStrategy);
			cfg.readFromJDBC();
			cfg.buildMappings();
			
			POJOExporter exporter = new POJOExporter(cfg,getOutputDir());		
			exporter.getProperties().setProperty("ejb3", "true");//ejb3注解
			exporter.getProperties().setProperty("jdk5", "true");//jdk5语法(主要是集合类的泛型处理)
			exporter.start();
			
//			exporter = new POJOExporter(xmlcfg,getOutputDir());				
//			exporter.start();
		
			//TestHelper.deleteDir(getOutputDir());
	}
	
	private File getOutputDir(){
		
		File file = new File("E:\\program\\javaws\\melon_2.0\\src\\core\\main\\test");//生成项目的物理位置（跟目录，tools会自动根据pacakge建立相应路径）
		return file;
	}

}

直接用junit或mian函数运行，而非依赖于jboss的插件，省的更新eclipse或者迁移的时候各种麻烦
副项目包备份
