运行导出程序#2时发生异常:hbm2ddl(生成数据库架构)

问题描述 投票:0回答:1

我正在尝试通过以下任务启动来生成dbSchema(Eclipse和Maven项目)

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<launchConfiguration type="org.eclipse.buildship.core.launch.runconfiguration">
<listAttribute key="arguments"/>
<stringAttribute key="gradle_distribution" value="GRADLE_DISTRIBUTION(WRAPPER)"/>
<listAttribute key="jvm_arguments"/>
<listAttribute key="org.eclipse.debug.ui.favoriteGroups">
<listEntry value="org.eclipse.debug.ui.launchGroup.run"/>
</listAttribute>
<booleanAttribute key="show_console_view" value="true"/>
<booleanAttribute key="show_execution_view" value="false"/>
<listAttribute key="tasks">
<listEntry value="dbSchema"/>
</listAttribute>
<booleanAttribute key="use_gradle_distribution_from_import" value="false"/>
<stringAttribute key="working_dir" value="${workspace_loc:/MyProject}"/>
</launchConfiguration>

这是控制台日志中的错误:

[ant:hibernatetool] An exception occurred while running exporter #2:hbm2ddl (Generates database schema)
[ant:hibernatetool] To get the full stack trace run ant with -verbose
[ant:hibernatetool] javax.persistence.PersistenceException: [PersistenceUnit: yadaPersistenceUnit] Unable to build Hibernate SessionFactory
[ant:hibernatetool] java.util.UnknownFormatConversionException: Conversion = '%'

此错误是由什么产生的?

[ant:hibernatetool] java.util.UnknownFormatConversionException: Conversion = '%'

如何解决这个问题?实体产生问题了吗?

到目前为止,该任务始终可以正常运行,我还没有进行任何更改。它可以依靠什么?

hibernate gradle ant schema hibernate-tools

这是由Settings类中的这一行引起的:

LOG.debugf("Using BatchFetchStyle : %", sessionFactoryOptions.getBatchFetchStyle().name());
