我正在使用 hibernate3-maven-plugin 在运行测试之前生成我的模式,它成功地创建了模式,但没有成功删除它。
我的插件配置:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<phase>process-test-classes</phase>
<goals>
<goal>hbm2ddl</goal>
</goals>
</execution>
</executions>
<configuration>
<components>
<component>
<name>hbm2ddl</name>
<implementation>annotationconfiguration</implementation>
</component>
</components>
<componentProperties>
<implementation>jpaconfiguration</implementation>
<persistenceunit>JpaPersistenceUnit</persistenceunit>
<configurationfile>src/test/resources/hibernate.cfg.xml</configurationfile>
</componentProperties>
</configuration>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.5</version>
</dependency>
</dependencies>
</plugin>
我的休眠xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost/db_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">root</property>
<property name="hibernate.connection.pool_size">1</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.hbm2ddl.auto">create-drop</property>
</session-factory>
</hibernate-configuration>
如您所见,我使用的是 hbm2ddl.auto=create-drop,文档状态应该在 SessionFactory 关闭时间删除数据库。
但是,当我第二次运行测试时,我看到以下错误:
[ERROR] Error #1: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'stations' already exists
[ERROR] Error #1: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'track_scans' already exists
(我目前只有两个实体,所以这似乎很合适)
我不知道从这里去哪里。任何帮助,将不胜感激。
