Question

有人可以帮我解决这个错误吗？或者有关如何使用JTA Transactionmanager的具体示例代码？

我正在使用多个数据库，主数据库是在带有Transactionmanager的Xml中定义的， and rest DB是在java文件中使用GenericApplicationContext创建的。

xml中的JtaTransactionManager设置就像这样

<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager" autowire="constructor">
   </bean>
<tx:annotation-driven/>

错误代码..

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in ServletContext resource [/WEB-INF/spring/db.xml]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: No JTA UserTransaction available - specify either 'userTransaction' or 'userTransactionName' or 'transactionManager' or 'transactionManagerName'

如果您使用JTA事务管理器，则需要：
1. Web服务器支持JTA，如JBoss，Weblogic 2.或JTA lib的实现，如atomikos。

因此，在您的情况下（使用tomcat），您应该使用JTA实现lib。如果你使用spring-boot，你只需将其添加到pom中，例如：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jta-atomikos</artifactId>
    </dependency>

而且，如果使用弹簧启动，则无需在配置中执行任何操作。

但是，您需要使用XADataSourceWrapper包装dataSource。您可以自动装配此属性并使用xaDataSourceWrapper.wrapDataSource()使数据源成为XA数据源。
