javax.persistence.PersistenceException：[PersistenceUnit：默認]無法解析命名的映射文件[hibernate.hbm.xml]

Question

我需要將一個休眠映射資源文件添加到spring上下文。 我不知道該怎么辦？

<context:annotation-config />
    <bean id="myEmf"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="ProjectManagerDataSource" />
        <property name="packagesToScan" value="com.ads" />
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
        </property>
        <property name="jpaProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                <prop key="hibernate.show_sql">true</prop>

            </props>
        </property>
    </bean>
    <bean id="ProjectManagerDataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url"
            value="jdbc:mysql://localhost:3306/project-management" />
        <property name="username" value="usera" />
        <property name="password" value="userausera" />
    </bean>

    <!-- <oxm:jaxb2-marshaller id="jaxbMarshallerBean"> -->
    <!-- <oxm:class-to-be-bound name="com.ads.configs.AppConfig" /> -->
    <!-- </oxm:jaxb2-marshaller> -->


    <jpa:repositories base-package="com.ads.dao"
        entity-manager-factory-ref="myEmf" />
    <tx:annotation-driven />
    <mvc:annotation-driven></mvc:annotation-driven>
    <context:component-scan base-package="com.ads.*" />
    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="myEmf" />
    </bean>

我已經與Session factory建立了一個解決方案，但是由於我正在使用實體管理器工廠，因此無法與我的項目一起使用。

更新：我的新問題是javax.persistence.PersistenceException發生了，所以我的堆棧跟蹤：

Answer 1

向您的org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean bean添加以下屬性

<property name="mappingResources">
            <value>com/your/package/resources/*.hbm.xml</value>
        </property>

Answer 2

我只是將文件的位置更改為src / main / resources即可解決問題。

Answer 3

這意味着您的映射文件orm.xml（如果使用JPA）或hbm.xml（如果使用hibernate）不在部署存檔中，或者它們位於錯誤的位置或在persistence.xml文件或文件名本身中被錯誤命名。

由於這些可能的原因，您的容器或運行時找不到在persistence.xml文件中聲明的所需文件。

映射文件應位於META-INF或WEB-INF下，具體取決於部署檔案類型。

在persistence.xml中，對於JPA聲明如下：

/META-INF/jpa/Entity-orm.xml

將解決可能的目錄相關問題。

假設Entity-orm.xml文件位於/ META-INF / jpa /目錄下。
