Spring:在 Java 配置中定义自定义 @Transactional 行为 [英] Spring: define custom @Transactional behavior in Java config

问题描述

我希望 Spring 在使用 @Transactional 注释的方法上回滚事务，以防该方法抛出已检查的异常.相当于:

I would like Spring to rollback a transaction on methods annotated with @Transactional in case the method throws a checked exception. An equivalent of this:

@Transactional(rollbackFor=MyCheckedException.class)
public void method() throws MyCheckedException {

}

但我需要将此行为作为所有 @Transactional 注释的默认值，而无需在任何地方编写它.我们使用Java来配置Spring(配置类).

But I need this behavior to be default for all @Transactional annotations without the need to write it everywhere. We are using Java to configure Spring (configuration classes).

我尝试了 spring 文档，仅在 XML 中可用.所以我尝试创建这个 XML 文件:

I tried the configuration suggested by spring documentation, which is only available in XML. So I tried to create this XML file:

<?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:aop="http://www.springframework.org/schema/aop"
 xmlns:tx="http://www.springframework.org/schema/tx"
 xsi:schemaLocation="
 http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans.xsd
 http://www.springframework.org/schema/tx
 http://www.springframework.org/schema/tx/spring-tx.xsd
 http://www.springframework.org/schema/aop
 http://www.springframework.org/schema/aop/spring-aop.xsd">

<tx:advice id="txAdvice" transaction-manager="txManager">
    <tx:attributes>
        <tx:method name="*" rollback-for="com.example.MyCheckedException" />
    </tx:attributes>
</tx:advice>

</beans>

... 并通过 @ImportResource 导入.Spring 确实识别并解析了该文件(一开始我有一些错误)，但它不起作用.@Transactional 的行为没有改变.

... and import it via @ImportResource. Spring did recognize and parse the file (I had some errors in it at first), but it doesn't work. The behavior of @Transactional has not changed.

我也尝试定义我自己的事务属性源，如这个答案中所建议的.但它也使用了 XML 配置，所以我不得不像这样将它转换成 Java:

I also tried defining my own transaction property source, as suggested in this answer. But it also used the XML configuration so I had to transform it into Java like this:

@Bean
public AnnotationTransactionAttributeSource getTransactionAttributeSource() {
    return new RollbackForAllAnnotationTransactionAttributeSource();
}

@Bean
public TransactionInterceptor getTransactionInterceptor(TransactionAttributeSource transactionAttributeSource) {

    TransactionInterceptor transactionInterceptor = new TransactionInterceptor();
    transactionInterceptor.setTransactionAttributeSource(transactionAttributeSource);

    return transactionInterceptor;
}

@Bean
public BeanFactoryTransactionAttributeSourceAdvisor getBeanFactoryTransactionAttributeSourceAdvisor(TransactionAttributeSource transactionAttributeSource) {

    BeanFactoryTransactionAttributeSourceAdvisor advisor = new BeanFactoryTransactionAttributeSourceAdvisor();

    advisor.setTransactionAttributeSource(transactionAttributeSource);

    return advisor;
}

这也不起作用 - Spring 一直使用自己的事务属性源(与在配置中创建的实例不同).

This also didn't work - Spring kept using its own transaction property source (different instance than the one which was created in the configuration).

在 Java 中实现这一目标的正确方法是什么?

What is the correct way to achieve this in Java?

推荐答案

你应该实现自己的注解 - 参考

You should rather implement own annotation - reference

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Transactional(rollbackFor=MyCheckedException.class)
public @interface TransactionalWithRollback {
}
