我在java.below中正在做hibernate示例是使用的代码

的hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"  "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

 <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
 <mapping  resource="table.hbm.xml"/>
 </session-factory>
 </hibernate-configuration>

table.hbm.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
 <hibernate-mapping>

 </id>  

  <property name="Name"  column="Name" type="string"></property>  
        </class>  
      </hibernate-mapping>    

inserttable.java

public class Inserttable {

public static void main(String[] args) {
    // TODO Auto-generated method stub
Configuration cfg = new Configuration();
cfg.configure("Hibernate.cfg.xml");
SessionFactory sf = cfg.buildSessionFactory();
Session s = sf.openSession();
Transaction tx = s.beginTransaction();
tabledata tab = new tabledata();
tab.setId(1);
tab.setName("mack");
s.save(tab);
s.flush();
tx.commit();
s.close();}
}

我正在使用mysql数据库,所以我使用的是mysql-connector,下面是使用的以下jar

mysql-connector-java-5.1.38-bin.jar
antlr-2.7.6.jar
cglib-2.2.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
Hibernate3.jar
Hibernate-jpa-2.0-api-1.0.0.Final.jar
Hibernate-Testing.jar
javassist-3.12.0.GA.jar
jta-1.1.jar
ehcache-1.2.3.jar
slf4j-jdk14-1.5.8.jar
slf4j-api-1.5.8.jar
commons-logging-1.0.4.jar

它显示以下错误

According to MySQL 5.5.45+,     5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if   explicit option isn't set. For compliance with existing applications not using   SSL the verifyServerCertificate property is set to 'false'. You need either to    explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide    truststore for server certificate verification.

请帮助我知道我的代码中的问题是什么,或者是关于添加jar文件的问题。我知道,任何帮助都表示赞赏。

编辑:在此之后也替换为tabledata.hbm.xml。我认为这将是hibernate学习初学者的好例子。

2 个答案:

答案 0 :(得分:1)

您的文件夹符合正确的约定

资源文件应位于src / main / resources

java files under src/main/java

虽然它不是必须遵循的,但是你应该自动消除一些问题,然后你就会转向惯例而不是配置。否则你可以在下面执行,因为hfg文件将能够从右侧文件夹中搜索hbm文件

答案 1 :(得分:0)

在您的文件Hibernate.cfg.xml中添加此

<mapping  resource="firsthb/table.hbm.xml"/>
