我正在使用flex,blazeds,hibernate jpa,tomcat和mysql。 這是我面臨的問題,當我啓動項目:無法在數據庫中通過persistence.xml使用Hibernate Jpa,Tomcat和Mysql添加表
05.06.2012 22:33:29.459 INFO org.hibernate.cfg.annotations.Version - Hibernate Annotations 3.4.0.GA

05.06.2012 22:33:29.650 INFO org.hibernate.ejb.Version - Hibernate EntityManager 3.4.0.GA
而且這是在src/META-INF我的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>
但是,如果我刪除該行:<class>com.adobe.demo.domain.User</class>
其他2個表將被創建。 我該怎麼辦?
究竟是什麼問題?您粘貼的日誌條目只是信息條目。用戶實體如何映射? –
當項目開始使用這3個類時,沒有實體會被添加到數據庫中,但是當我刪除User類時,他們會添加其他2個類。 – user1438406
我認爲在mysql中已經存在用於管理帳戶的'user'表。 –
