Question

我想为OneToMany关系配置persistence.xml文件。我的IDE是NetBeans。我的坚持是这样的：＆lt;？xml version =＆＃34; 1.0＆＃34;编码=＆＃34; UTF-8＆＃34;＆GT; ＆lt; persistence version =＆＃34; 2.0＆＃34;的xmlns =＆＃34; HTTP：//java.sun.com/xml/ns/persistence"的xmlns：=的xsi＆＃34; HTTP：//www.w3.org/2001/XMLSchema-instance" xsi：schemaLocation =＆＃34; http：//java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> ＆lt;！ - 将在Spring Context File中引用 - ＆gt; ＆lt; persistence-unit name =＆＃34; jpa-persistence＆＃34;交易类型=＆＃34; RESOURCE_LOCAL＆＃34;＆GT; ＆LT;类＆GT; co.trainingproject.models.User＆LT; /类＆GT; ＆LT;类＆GT; co.trainingproject.models.Category＆LT; /类＆GT; ＆LT;类＆GT; co.trainingproject.models.Topic＆LT; /类＆GT; ＆LT;性状＆gt; ＆lt; property name =＆＃34; javax.persistence.jdbc.url＆＃34;值=＆＃34; JDBC：MySQL的：//本地主机：3306 / trainingdb＆＃34; /＆GT; ＆lt; property name =＆＃34; javax.persistence.jdbc.user＆＃34;值=＆＃34;根＆＃34; /＆GT; ＆lt; property name =＆＃34; javax.persistence.jdbc.driver＆＃34;值=＆＃34; com.mysql.jdbc.Driver＆＃34; /＆GT; ＆lt; property name =＆＃34; javax.persistence.jdbc.password＆＃34;值=＃＆34; 123456＆＃34; /＆GT; ＆LT; /性状＆gt; ＆LT; /持久性单元＆gt; ＆LT; /持久＆GT; 和Category.java： @OneToMany（mappedBy =＆＃34; idcategory＆＃34;，cascade = CascadeType.ALL）私人清单＆lt;主题＆gt;题目列表; 和Topic.java： @ManyToOne @JoinColumn（name =＆＃34; idcategory＆＃34;，referencedColumnName =＆＃34; idcategory＆＃34;）私人类别idcategory; applicationContext.xml中：＆lt;？xml version =＆＃34; 1.0＆＃34;编码=＆＃34; UTF-8＆＃34;＆GT; ＆lt; beans xmlns =＆＃34; http：//www.springframework.org/schema/beans" 的xmlns：=的xsi＆＃34; HTTP：//www.w3.org/2001/XMLSchema-instance"的xmlns：TX =＆＃34; HTTP：//www.springframework.org/schema/tx" 的xmlns：上下文=＆＃34; HTTP：//www.springframework.org/schema/context" 的xmlns：AOP =＆＃34; HTTP：//www.springframework.org/schema/aop"的xmlns：UTIL =＆＃34; HTTP：//www.springframework.org/schema/util" xsi：schemaLocation =＆＃34; http：//www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/ schema / aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring -context-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd"> ＆lt;！ - 启用Spring注释配置 - ＆gt; ＆lt; context：annotation-config /＆gt; ＆lt;！ - 扫描所有Spring组件，例如Spring Service - ＆gt; ＆lt; context：component-scan base-package =＆＃34; co.trainingproject＆＃34;＆gt;＆lt; / context：component-scan＆gt; ＆lt;！ - 将实体管理器注入工厂bean所必需的 - ＆gt; ＆lt; bean class =＆＃34; org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor＆＃34; /＆GT; ＆lt;！ - 定义EclipseLink JPA供应商适配器 - ＆gt; ＆lt; bean id =＆＃34; jpaVendorAdapter＆＃34; 类=＆＃34; org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter＆＃34;＆GT; ＆lt; property name =＆＃34; databasePlatform＆＃34; 值=＆＃34; org.eclipse.persistence.platform.database.MySQLPlatform＆＃34; /＆GT; ＆lt; property name =＆＃34; generateDdl＆＃34;值=＆＃34;假＆＃34; /＆GT; ＆lt; property name =＆＃34; showSql＆＃34;值=＆＃34;真＆＃34; /＆GT; ＆LT; /豆腐＆GT; ＆lt;！ - 定义Hibernate JPA供应商适配器 - ＆gt; ＆lt;！ - ＆lt; bean id =＆＃34; jpaVendorAdapter＆＃34; 类=＆＃34; org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter＆＃34;＆GT; ＆lt; property name =＆＃34; databasePlatform＆＃34; 值=＆＃34; org.hibernate.dialect.MySQLDialect＆＃34; /＆GT; ＆LT; /豆腐＆GT; - ＆GT; ＆lt;！ - 实体经理工厂 - ＆gt; ＆lt; bean id =＆＃34; entityManagerFactory＆＃34; 类=＆＃34; org.springframework.orm.jpa.LocalEntityManagerFactoryBean＆＃34;＆GT; ＆lt; property name =＆＃34; persistenceUnitName＆＃34;值=＆＃34; JP-A-持久＆＃34;＆GT;＆LT; /性＆gt; ＆lt; property name =＆＃34; jpaVendorAdapter＆＃34; REF =＆＃34; jpaVendorAdapter＆＃34; /＆GT; ＆LT; /豆腐＆GT; ＆lt;！ - 事务管理器 - ＆gt; ＆lt; bean id =＆＃34; transactionManager＆＃34;类=＆＃34; org.springframework.orm.jpa.JpaTransactionManager＆＃34;＆GT; ＆lt; property name =＆＃34; entityManagerFactory＆＃34; REF =＆＃34;的entityManagerFactory＆＃34; /＆GT; ＆LT; /豆腐＆GT; ＆lt;！ - 检测@Transactional - ＆gt; ＆lt; tx：annotation-driven transaction-manager =＆＃34; transactionManager＆＃34; /＆GT; ＆LT; /豆类＆GT; 我认为这些文件需要另一个设置，因为当我想在glassfish中部署我的项目时，会发生以下错误：发生异常：部署期间发生错误：加载应用程序时出现异常：java.lang.IllegalStateException：ContainerBase.addChild：start：org.apache.catalina.LifecycleException：org.springframework.beans.factory.BeanCreationException：创建名称为＆的bean时出错＃39; categoryService＆＃39 ;:持久性依赖注入失败;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名称为＆＃39; entityManagerFactory＆＃39;的bean时出错。在ServletContext资源[/WEB-INF/applicationContext.xml]中定义：init方法的调用失败;嵌套异常是Exception [EclipseLink-30005]（Eclipse Persistence Services - 2.5.0.v20130507-3faac2b）：org.eclipse.persistence.exceptions.PersistenceUnitLoadingException 异常描述：使用ClassLoader搜索持久性归档时抛出异常：WebappClassLoader（delegate = true; repositories = WEB-INF / classes /）

Answer 1

此错误与NetBeans有关。看this. 我在glassfish4 / bin中写道：

./asadmin add-resources ~/NetBeansProjects/../web/WEB-INF/glassfish-resources.xml

配置persistence.xml JPA
