java - 定义 HibernateExceptionTranslator : No persistence exception translators found in bean factory

Question

我正在尝试在我的项目中注入(inject)一个 eventRepository，它是 Spring Data Repository:

public class App {

    protected static EntityManagerFactory factory;

    @Autowired
    protected EventRepository eventRepository;

    public void execute() {
        Event foo = eventRepository.findBySlug("abraxas");
    }

    public static void main(String[] args) {
        ApplicationContext context =
                new ClassPathXmlApplicationContext("beans.xml");

        App runner = (App) context.getBean("AppBean");
        runner.execute();
    }
}

beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jpa="http://www.springframework.org/schema/data/jpa"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/data/jpa
            http://www.springframework.org/schema/data/jpa/spring-jpa.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <bean id="AppBean" class="org.app.App"></bean>
    <jpa:repositories base-package="org.app.repository" />
</beans>

但是当我运行它时出现以下异常:

java.lang.IllegalStateException: No persistence exception translators found in bean factory. Cannot perform exception translation.at org.springframework.dao.support.PersistenceExceptionTranslationInterceptor.detectPersistenceExceptionTranslators

在一些评论中，我发现我需要“配置 HibernateExceptionTranslator”，但我没有找到如何配置。

我正在尝试关注 official documentation其中没有提到 HibernateExceptionTranslator 的配置。

谢谢

Answer 1

显然解决方案是添加

     <bean class="org.springframework.orm.hibernate4.HibernateExceptionTranslator"/>

到 beans.xml
