SS3.3_Hibernate_Log4j&JUnit 日志处理框架和单元测试

SS3.3_Hibernate_Log4j&JUnit项目由项目SS3.2_Hibernate_Annotation拷贝而来，项目结构截图如下：

创建log4j.properties日志配置文件：

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n


### direct messages to file hibernate.log ###
#log4j.appender.file=org.apache.log4j.FileAppender
#log4j.appender.file.File=hibernate.log
#log4j.appender.file.layout=org.apache.log4j.PatternLayout
#log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n


### set log levels - for more verbose logging change 'info' to 'debug' ###


log4j.rootLogger=warn, stdout


#log4j.logger.org.hibernate=info
#log4j.logger.org.hibernate=debug


### log HQL query parser activity
#log4j.logger.org.hibernate.hql.ast.AST=debug


### log just the SQL
log4j.logger.org.hibernate.SQL=debug


### log JDBC bind parameters ###
log4j.logger.org.hibernate.type=info
#log4j.logger.org.hibernate.type=debug


### log schema export/update ###
log4j.logger.org.hibernate.tool.hbm2ddl=debug


### log HQL parse trees
#log4j.logger.org.hibernate.hql=debug


### log cache activity ###
#log4j.logger.org.hibernate.cache=debug


### log transaction activity
log4j.logger.org.hibernate.transaction=debug


### log JDBC resource acquisition
#log4j.logger.org.hibernate.jdbc=debug


### enable the following line if you want to track down connection ###
### leakages when using DriverManagerConnectionProvider ###
#log4j.logger.org.hibernate.connection.DriverManagerConnectionProvider=trace

运行项目控制台输出如下信息：

新建单元测试类，继承TestCase，根据移动鼠标到TestCase上提示的信息，点击Add Unit 3导入开发工具集成的单元测试软件包：

package net.nw.vo;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.AnnotationConfiguration;
import junit.framework.TestCase;
public class TestStudent extends TestCase {
private static SessionFactory sessionFactory ;

@Override
protected void setUp() throws Exception {
System.out.println("setUp()...");
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
}

@Override
protected void tearDown() throws Exception {
System.out.println("tearDown()...");
sessionFactory.close();
}

public  void testSave(){
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
try{
Student s = new Student();
s.setSname("wangwu");
session.save(s);
tx.commit();
}catch(Exception ex){
tx.rollback();
ex.printStackTrace();
}finally{
if(session !=null){
session.close();
}
}
}

}

执行单元测试，效果截图如下：
