上面注解的主要作用就是帮我们Import了TransactionManagementConfigurationSelector这个类,它的主要功能如下: 这个类目前就是帮我们在Spring中注入了ProxyTransactionManagementConfiguration,大家一看名称就知道这是一个配置类(配置类一般都是帮我们注入各种需要的Bean)如下它帮我们做的事情。 @Bean(name = TransactionManagement...
Local transactions are resource-specific, such as a transaction associated with a JDBC connection.Local transactions may be easier to use, but have significant disadvantages: they cannot work across multiple transactional resources. For example, code that manages transactions using a JDBC connection canno...
首先从配置入手,启用Spring的TransactionManagement需要在Configuration Bean上加上@EnableTransactionManagement注解,或者在XML配置文件中加上<tx:annotation-driver />元素来启用事务支持,这样我们将会在Spring Context里面注册事务支持所需要的组件,比如Interceptor, Advisor等等。
1、使用@EnableTransactionManagement,解析@Import注解上的信息 2、TransactionManagementConfigurationSelector实现了AdviceModeImportSelector扩展类,达到注解Bean的效果 3、如果使用默认形式代理,则会初始化类ProxyTransactionManagementConfiguration,在该类的主要作用是初始化一个advisor。熟悉AOP的小伙伴应该都知道,Spring中的事...
Nested transactions in Spring are just JDBC / database savepoints. If you don’t know what a savepoint is, have a look atthis tutorial, for example. Note that savepoint support is dependent on your JDBC driver/database. How Spring’s or Spring Boot’s Transaction Management works ...
In rest of the article, we discuss with an example, declarative transaction management with Spring. For this tutorial you will need: (1)Spring 3.0 (2)Eclipseis optional. I use eclipse as my IDE. Eclipse lets you export the war that can be deployed to Tomcat. But you can use other IDEs...
