Question

我正在为spring数据写例子。这是我的spring.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">

<context:component-scan base-package="com.currencyconverter.entity" />

<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="database.properties" />
</bean>

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="${driver.name}" />
    <property name="url" value="${database.url}" />
    <property name="username" value="${database.username}" />
    <property name="password" value="${database.password}" />
</bean>

<bean id="currencyRateImpl" class="com.currencyconverter.dao.CurrencyRateImpl">
    <property name="dataSource" ref="dataSource" />
</bean>


<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.currencyconverter.entity" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.hbm2ddl.auto">create-drop</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
        </props>
    </property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

这些是我的pom.xml

中的依赖项

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>

我没有使用过persistence.xml 。我得到了以下异常

引起：java.lang.NoSuchMethodError：javax.persistence.spi.PersistenceUnitInfo.getValidationMode（）Ljavax / persistence / ValidationMode; 在org.hibernate.jpa.boot.internal.PersistenceUnitInfoDescriptor.getValidationMode（PersistenceUnitInfoDescriptor.java:99）在org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.mergePropertySources（EntityManagerFactoryBuilderImpl.java:567）在org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl。（EntityManagerFactoryBuilderImpl.java:212）在org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl。（EntityManagerFactoryBuilderImpl.java:186）在org.hibernate.jpa.boot.spi.Bootstrap.getEntityManagerFactoryBuilder（Bootstrap.java:45）在org.hibernate.jpa.boot.spi.Bootstrap.getEntityManagerFactoryBuilder（Bootstrap.java:57）在org.hibernate.jpa.HibernatePersistenceProvider.createContainerEntityManagerFactory（HibernatePersistenceProvider.java:150）在org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory（HibernatePersistence.java:67）在org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory（LocalContainerEntityManagerFactoryBean.java:288）在org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.afterPropertiesSet（AbstractEntityManagerFactoryBean.java:310）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods（AbstractAutowireCapableBeanFactory.java:1571）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFactory.java:1509） ......还有12个

代码出了什么问题。依赖项和版本都是正确的。对于spring 3.2来说，persistance.xml是必需的。如果是，那么它应该包含什么。

Answer 1

发生此错误是因为引入了JPA 1 API，但方法getValidationMode仅在JPA 2之后才存在。

而不是关注

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>1.0.2</version>
</dependency>

例如，可以使用Hibernate提供的一个：

<dependency>
  <groupId>org.hibernate.javax.persistence</groupId>
  <artifactId>hibernate-jpa-2.0-api</artifactId>
  <version>1.0.1.Final</version>
</dependency>

java.lang.NoSuchMethodError：javax.persistence.spi.PersistenceUnitInfo.getValidationMode（）Ljavax / persistence / ValidationMode;
