hibernate - Spring 抛出 JpaSystemException 而不是 DuplicateKeyException

Question

我在处理 DataAccessException 时遇到了麻烦。

当违反唯一键约束时，我得到了 JpaSystemException，而不是 DuplicateKeyException!

我发现一些线程在谈论这个问题，但没有人帮我解决这个问题。如何映射到具体的 org.springframework.dao 异常？

我的 persistence.xml 文件如下所示:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

            <property name="hibernate.showsql" value="true"/>           
        </properties>
    </persistence-unit> 
</persistence>

以及关于mysql事务管理器的配置:

<bean id="entityManagerFactory" 
          class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
          p:dataSource-ref="dataSource"
          p:persistenceUnitName="persistenceUnit"
          p:jpaProperties="">
          <property name="jpaVendorAdapter">
        <bean
          class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
              <property name="showSql" value="true" />
              <property name="databasePlatform" value="org.hibernate.dialect.MySQL5InnoDBDialect" />
              <property name="database" value="MYSQL"/>           
         </bean>
       </property>
           <property name="jpaDialect">
         <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
           </property>
    </bean>

    <bean id="transactionManager"
          class="org.springframework.orm.jpa.JpaTransactionManager"
          p:entityManagerFactory-ref="entityManagerFactory"/>

    <tx:annotation-driven transaction-manager="transactionManager" />

我省略了关于 sqlserver 的配置，因为我认为这无关紧要。我对这个数据库的翻译错误不感兴趣。

我还包括了 bean :

<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>

尝试进行以下简单的junit测试:

@Test(expected=DuplicateKeyException.class)
public void createNewUbi(){
    Ubi ubi = new Ubi();
    ubi.setCode("A");
    ubiDao.save(ubi);       

    ubi = new Ubi();
    ubi.setCode("A");

    ubiDao.save(ubi);                   
}

我从我的日志中得到:

ERROR: org.hibernate.util.JDBCExceptionReporter - Duplicate entry 'A' for key 'code'

捕捉到第二个保存调用的异常，我注意到我有:

JpaSystemException: cause: javax.persistence.PersistenceException
PersistenceException: cause: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException 

如果我尝试从 webapp 进行插入，则会出现此异常:

我已启用 mysql 查询日志记录，并得到以下查询:

insert into ubi (code, version) values ('A', 0)

如果我尝试从 mysql 控制台执行查询，我会得到: ERROR 1062 (23000): Duplicate entry 'A' for key 'code'
正在搜索 sql-error-codes.xml包装内 org.springframework.jdbc.support的 spring-jdbc-3.0.6.RELEASE.jar我发现对于 mysql db，错误代码 1062 是这样配置的:

<property name="duplicateKeyCodes">
    <value>1062</value>
</property>

所以我认为由于配置错误的属性存在一些异常翻译问题..但是哪个？

我正在使用 Spring 3.0.6.RELEASE 和 Hibernate 3.6.9.FINAL

感谢您的任何回复!

Answer 1

确保您的 EntityManager有一个 vendorAdapter设置它。这将允许您的 jpa 提供商提供高级错误代码。
