我的项目出现以下异常:
Class "com.testApp.domain.Register" is managed, but is not listed in the persistence.xml file
我的 persistence.xml
文件如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
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_2_0.xsd">
<persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<properties>

<property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver" />
<property name="hibernate.connection.url" value="jdbc:hsqldb:mem:." />
<property name="hibernate.connection.username" value="SA" />
<property name="hibernate.connection.password" value="" />
<property name="hibernate.c3p0.min_size" value="5" />
<property name="hibernate.c3p0.max_size" value="20" />
<property name="hibernate.c3p0.timeout" value="300" />
<property name="hibernate.c3p0.max_statements" value="50" />
<property name="hibernate.c3p0.idle_test_period" value="3000" />
</properties>
</persistence-unit>
</persistence>
我试过这个post和 this ,两者都建议手动或自动将类添加到 persistence.xml
。其他人说这是一个与 eclipse 相关的问题,可以通过清理或重新打开项目来解决。但是,我希望 hibernate 能够自动检测到这些类,而不是手动将它们添加到我的 persistence.xml
中。
对解决方案和解决我的错误有什么建议吗?
感谢您的回复!
更新
我的applicationContext.xml
:

最佳答案
如果您使用的是 Eclipse:(1) 选择:(您的项目)-> 属性 -> JPA; (2) 寻找“Persistent class management”并选择“Discover annotated classes automatically”选项; (3) 按“应用”。
