Spring Hibernate集成错误，属性转换错误
[英]spring hibernate integration error , propery conversion error
问题描述
我使用mysql作为数据库，创建了实体，并创建了persistence.xml。 但是我在运行/部署Web应用程序时遇到与在beanfactory中创建bean有关的异常。
春季版本是4.0.6.RELEASE
休眠版本是4.3.5.Final
spring jpa版本是1.6.2.RELEASE
root-context.xml文件是
<!-- Root Context: defines shared resources visible to all other web components -->
<context:component-scan base-package="com.sarathraj.springdata" />
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/springdb" />
<property name="username" value="root" />
<property name="password" value="root" />
</bean>
<bean id="jpaventor" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" >
<property name="database" value="MYSQL"/>
<property name="showSql" value="true"/>
<property name="generateDdl" value="true"/>
<property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect"/>
</bean>

<property name="dataSource" ref="dataSource"></property>
<property name="jpaProperties" ref="jpaventor"></property>
<property name="persistenceUnitName" value="SpringMVCExample"/>
</bean>
<!-- <tx:annotation-driven transaction-manager="transactionManager" />
<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">

<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="emf" />
</bean>
persistance.xml
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

<class>com.sarathraj.springdata.entity.Blog</class>

</persistence>
例外是

您为属性“ jpaProperties”传递了错误的对象
<property name="jpaProperties" ref="jpaventor"></property>
jpaventor bean的类型为HibernateJpaVendorAdapter 。 但是jpaProperties属性使用类型为java.util.Properties的bean。
传递正确的对象引用将解决您的问题
