如何解决我的第一个Hibernate项目的错误？ [英] How to fix error with my first Hibernate project?
问题描述
antlr-2.7.7
commons-collections-3.2.1
dom4j-1.6.1
hibernate-commons-annotations-4.0.1.Final
hibernate-core-4.1.0.Final
hibernate-jpa-2.0-api-1.0.1.Final
javassist-3.15 .0 -GA
jboss-logging-3.1.0.CR2
jboss-transaction-api_1.1_spec-1.0.0.Final
mysql-connector-java-5.1.18-bin
hibernate.cfg.xml：
<？xml version = 1.0encoding =UTF-8？>
<！DOCTYPE hibernate-configuration PUBLIC - // Hibernate / Hibernate Configuration DTD // EN
http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd\">

< property name =hibernate.dialect> org.hibernate.dialect.MySQL5Dialect< / property>
< mapping class =com.nda.hibernate.Person/>
< / session-factory>
< / hibernate-configuration>
Person.class：
package com.nda.hibernate;
import javax.persistence.Entity;
import javax.persistence.Id;
@实体
公共类人物{
私人字符串名称;
@Id
private int number;
public Person（）{}
$ b $ public Person（String name，int number）{
this.name = name;
this.number = number;
}
public void setName（String name）{
this.name = name;
}
public String getName（）{
return name;
}
public void setNumber（int number）{
this.number = number;
}
public int getNumber（）{
return number;
}
}
我安装了Denwer。使用的参数：login - root，密码为空。服务器是本地主机，并具有数据库测试与表人（CHAR（50）名称，INT（10）号码 - 主键）
Main.class：
SessionFactory sessions = new AnnotationConfiguration（）。configure（）。buildSessionFactory（）;
Session session = sessions.openSession（）;
它不起作用。我有一些错误：

我该如何解决它？谢谢。
这些看起来都不像我的错误 - 它们只是日志行。这里唯一的问题是一个警告：
警告：HHH000223：已识别的过时hibernate命名空间
http://hibernate.sourceforge.net/ 。改为使用名称空间 http://www.hibernate.org/dtd/ 。请参考Hibernate 3.6迁移指南！
这只是一个警告 - 值得修复，但听起来好像不是很糟糕 em>紧急。
其他一切都只是在INFO级别......所以不要担心它们。继续前进，看看你的代码在数据库访问方面是否符合你的期望。
I have been tried to make my first Hibernate project. I added following libraries into my project:
antlr-2.7.7 commons-collections-3.2.1 dom4j-1.6.1 hibernate-commons-annotations-4.0.1.Final hibernate-core-4.1.0.Final hibernate-jpa-2.0-api-1.0.1.Final javassist-3.15.0-GA jboss-logging-3.1.0.CR2 jboss-transaction-api_1.1_spec-1.0.0.Final mysql-connector-java-5.1.18-bin
hibernate.cfg.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.url">jdbc:mysql://localhost/test</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password"></property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
<mapping class="com.nda.hibernate.Person"/>
</session-factory>
</hibernate-configuration>
Person.class:
package com.nda.hibernate;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class Person {
private String name;
@Id
private int number;
public Person() {}
public Person(String name, int number) {
this.name=name;
this.number=number;
}
public void setName(String name) {
this.name=name;
}
public String getName() {
return name;
}
public void setNumber(int number) {
this.number=number;
}
public int getNumber() {
return number;
}
}
I have Denwer installed. Parameters for using: login - root, password is empty. Server is localhost, and has database "test" with table "person"(CHAR(50) name, INT(10) number - primary key)
Main.class:
SessionFactory sessions=new AnnotationConfiguration().configure().buildSessionFactory();
Session session=sessions.openSession();
It doesn't work. I have got some errors:

How can I fix it? Thank you.
None of those look like errors to me - they're just log lines. The only "problem" is a warning here:
WARN: HHH000223: Recognized obsolete hibernate namespace http://hibernate.sourceforge.net/. Use namespace http://www.hibernate.org/dtd/ instead. Refer to Hibernate 3.6 Migration Guide!
That's only a warning - worth fixing, but it sounds like it's not terribly urgent.
Everything else is just at INFO level... so don't worry about them. Just keep going, and see whether your code does what you expect in terms of database access.
