1、叮嘣HibernateAnnotation叮嘣使用hibernateAnnotation来映射实体准备工作下载hibernate-distribution-3.3.2.GAhibernate-annotations-3.4.0.GAslf4j导入相关依赖包HibernateHOME：hibernate3.jarlibbytecode（二进制）liboptional（可选的）librequired（必须的）导入required下的所有jar包antlr-2.7.6.jarcommon

2、s-collections-3.1.jardom4j-1.6.1.jarhibernate3.jarjavassist-3.9.0.GA.jarjta-1.1.jarslf4j-api-1.5.10.jarslf4j-log4j12-1.5.10.jarlog4j-1.2.14.jarmysql.jar---Annotation包ejb3-persistence.jarhibernate-annotations.jarhibernate-commons-annotations.jar叮嘣简单的例

3、子，通过annotation注解来映射实体PO1、建立（JavaProject）项目：hibernate_0100_annotation_HelloWorld_default2、在项目根下建立lib目录a)导入相关依赖jar包antlr-2.7.6.jarcommons-collections-3.1.jardom4j-1.6.1.jarejb3-persistence.jarhibernate-annotations.jarhibernate-commons-annotations.jarhi

5、itypublicclassTeacher{privateintid;privateStringusername;privateStringpassword;//ID为主键，主键手动分配@IdpublicintgetId(){returnid;}publicvoidsetId(intid){this.id=id;叮嘣}publicStringgetUsername(){returnusername;}publicvoidsetUsername(Stringusername){this.usern

6、ame=username;}publicStringgetPassword(){returnpassword;}publicvoidsetPassword(Stringpassword){this.password=password;}}3、在src目录中建立hibernate.cfg.xml（hibernate配置文件）文件，内容如下
