Question

我正在使用flex，blazeds，hibernate jpa，tomcat和mysql。这是我开始项目时遇到的问题：

05.06.2012 22:33:29.459  INFO     org.hibernate.cfg.annotations.Version     - Hibernate Annotations 3.4.0.GA
05.06.2012 22:33:29.479  INFO     org.hibernate.cfg.Environment             - Hibernate 3.3.2.GA

05.06.2012 22:33:29.487  INFO     org.hibernate.cfg.Environment             - Bytecode provider name : javassist

05.06.2012 22:33:29.645  INFO     org.hibernate.annotations.common.Version  - Hibernate Commons Annotations 3.1.0.GA

这是我在src / META-INF下的persistence.xml文件：

<persistence version="1.0"
xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

<persistence-unit name="consultant_db">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>


    <class>com.adobe.demo.domain.Permission</class>
    <class>com.adobe.demo.domain.Role</class>
    <class>com.adobe.demo.domain.User</class>

    <properties>
        <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
        <property name="hibernate.connection.url" value="jdbc:mysql://localhost/consultant_db" />
        <property name="hibernate.connection.username" value="root" />
        <property name="hibernate.connection.password" value="" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" />

        <property name="hibernate.connection.pool_size" value="6" />
        <property name="hibernate.connection.autoReconnect" value="true" />
        <property name="hibernate.generate_statistics" value="false" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.use_sql_comments" value="false" />
        <property name="hibernate.hbm2ddl.auto" value="update" />
    </properties>


</persistence-unit>

但如果删除该行：<class>com.adobe.demo.domain.User</class> 将创建其他2个表。我该怎么办？

Answer 1

Here是一个类似的问题。 OP试图创建一个失败的“用户”表。 OP能够通过注释User课程@Table(name = "\"user\"")来解决问题。

我还提供了一些如何解决此类问题的提示。

无法使用Hibernate Jpa，Tomcat和Mysql通过persistence.xml在Database中添加表
