Question

我无法在我的所有表格中插入数据，选择无问题的作品。使用的用户有权插入数据，我也尝试手动插入数据。

hibernate.cfg，hibernate.reveng和hbm.xml等所有配置文件都由NetBeans生成。

Event.hbm.xml：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!-- Generated Apr 20, 2015 10:05:17 AM by Hibernate Tools 4.3.1 -->
<hibernate-mapping>
    <class name="at.ac.univie.salome.domain.Event" table="event" catalog="salomeapp" optimistic-lock="version">
        <id name="id" type="java.lang.Integer">
            <column name="id" />
            <generator class="identity" />
        </id>
        <property name="title" type="string">
            <column name="title" not-null="true" />
        </property>
        <property name="desc" type="string">
            <column name="desc" length="1024" />
        </property>
        <set name="partitions" table="partition" inverse="true" lazy="true" fetch="select">
            <key>
                <column name="event_id" not-null="true" />
            </key>
            <one-to-many class="at.ac.univie.salome.domain.Partition" />
        </set>
    </class>
</hibernate-mapping>

的hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/salomeapp?zeroDateTimeBehavior=convertToNull</property>
    <property name="hibernate.connection.username">******</property>
    <property name="hibernate.connection.password">******</property>
    <property name="hibernate.show_sql">true</property>
    <property name="hibernate.current_session_context_class">thread</property>
    <mapping resource="at/ac/univie/salome/domain/Partition.hbm.xml"/>
    <mapping resource="at/ac/univie/salome/domain/Chunk.hbm.xml"/>
    <mapping resource="at/ac/univie/salome/domain/Event.hbm.xml"/>
  </session-factory>
</hibernate-configuration>

例外：

我正在使用Netbeans，Glassfish 4，Hibernate 4.3和MySQL 5.6.23。

我认为您正在尝试在实体中使用保留列名称。尝试更改列名称。
