Answer 1

hibernate.cfg.xml配置如下
<session-factory>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/gradesys</property>
        <property name="connection.username">root</property>
        <property name="connection.password">ncistjk1973</property>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="current_session_context_class">thread</property>
        
        <mapping class="bean.Teacher"/>
        <mapping class="bean.Course"/>
    
    </session-factory>
修改的HibernateSessionFactory配置
      private  static Configuration configuration = new AnnotationConfiguration();  
报错：

Answer 2

Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
你的common-loggin.jar包加进去了？

Answer 3

g4j-1.2.16.jar slf4j-api-1.6.1.jar slf4j-log4j12-1.6.1.jar倒入这3个包

Answer 4

log4j-1.2.16.jar slf4j-api-1.6.1.jar slf4j-log4j12-1.6.1.jar倒入这3个包

Answer 5

Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory
这个不是很明白了吗？缺少slf4j，导入即可···

Answer 6

刚开始没有引进commons-loggin.jar包，不过引进后还是报相同的错误。引进sl4fj-api-1.5.8.jar包和sl4fj-log4j12-1.5.8.jar包后，报错

上面几位说的几个包，包括log4j-1.2.16.jar， slf4j-api-1.6.1.jar， slf4j-log4j12-1.6.1.jar，commons-loggin.jar还有ejb3-persistence.jar，hibernate-annotations.jar，hibernate-commons-annotations.jar，mysql-connector-java-5.0.8-bin-g.jar，可是还是报同样的错误

Answer 8

是啊，可是把log4j的版本升级到log4j-1.2.12.jar，它报的还是一样的错误，纠结死了都

Answer 9

Teacher配置不变，把Course的ManyToMany改为如下，我的多对多都是这样配置的：package bean;import java.util.*;
import javax.persistence.*;@Entity
@Table(name="course")
public class Course {
    @Id
    @TableGenerator(name="course",allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.TABLE,generator="course")
    private String cno;
    
    @Column(name="cname")
    private String name;
    
    @ManyToMany(fetch = FetchType.LAZY, mappedBy = "courses",targetEntity = Teacher.class)
    private Set<Teacher> teachers = new HashSet<Teacher>();    public String getCno() {
        return cno;
    }    public void setCno(String cno) {
        this.cno = cno;
    }    public String getName() {
        return name;
    }    public void setName(String name) {
        this.name = name;
    }
    
    public void setTeachers(Set<Teacher> teachers) {
        this.teachers = teachers;
    }
    
    public Set getTeachers(){
        return this.teachers;
    }
        public Course() {    }    public Course(String cno, String name) {
        this.cno = cno;
        this.name = name;
    }
    
}

Answer 10

不行啊，还是报相同的错误！
想想teacour那张表示用复合主键而我却没有进行相应的配置，待会弄弄看能否解决不

Answer 11

把 jar 包导入就好了啊 ～～

Answer 12

Caused by: java.lang.ClassNotFoundException: org.hibernate.engine.query.sql.NativeSQLQueryReturn换个Hibernate3的版本试试，例如3.3.2

Answer 13

大家有没有好用的hibernate引用的jar包组合呀

Answer 14

log4j-1.2.12.jar换成log4j-1.2.16.jar 然后再查看是否有slf4j-api-1.6.4.jar包没有就添加进去
