The mentioned integration is achieved by providing implementations of the +`TransactionManager` Spring Transactions interface. There are two such implementations: `SpringTransactionManager` and +`IgniteClientSpringTransactionManager`, which use Apache Ignite node or Apache Ignite thin client to connect to the +Apache Ignite cluster and manage the Apache Ignite transactions, respectively. + +To enable declarative transaction management in your Spring application, create and configure +`SpringTransactionManager` or `IgniteClientSpringTransactionManager` bean in the Spring application context. The choice +of implementation depends on your preferable way to access the Apache Ignite cluster. + +== Maven Configuration + +If you are using Maven to manage dependencies in your project, you can add Spring Transactions extension dependencies to +the application's `pom.xml` file like this: + +[NOTE] +==== +For Apache Ignite versions earlier than `2.11.0`, the `ignite-spring-tx-ext` dependency must be added to +classpath before `ignite-spring`, due to duplication of Spring Transactions integration classes. If you are using Maven +to manage dependencies, it just needs to place `ignite-spring-tx-ext` before the `ignite-spring` dependency in the +application's `pom.xml` file. +==== + +[tabs] +-- +tab:pom.xml[] +[source,xml] +---- +<dependency> + <groupId>org.apache.ignite</groupId> + <artifactId>ignite-spring-tx-ext</artifactId> + <version>${ignite-spring-tx-ext.version}</version> +</dependency> + +<dependency> + <groupId>org.apache.ignite</groupId> + <artifactId>ignite-spring</artifactId> + <version>${ignite.version}</version> +</dependency> + +<dependency> + <groupId>org.apache.ignite</groupId> + <artifactId>ignite-core</artifactId> + <version>${ignite.version}</version> +</dependency> + +<dependency> + <groupId>org.springframework</groupId> + <artifactId>spring-tx</artifactId> + <version>${spring.version}</version> +</dependency> +---- +-- + +Replace `${ignite-spring-tx-ext.version}`, `${spring.version}`, and +`${ignite.version}` with an actual version of Apache Ignite Spring Transactions extension, Spring Transactions, and +Apache Ignite dependency you are interested in, respectively. + +== Apache Ignite Node Transaction Manager Configuration +This chapter shows how to set up `SpringTransactionManager` that relies on Apache Ignite node to connect to the cluster +and manage transactions. The configuration consists of two steps - +link:extensions-and-integrations/spring/spring-tx#cluster-connection-configuration[cluster connection configuration] +and link:extensions-and-integrations/spring/spring-tx#transaction-concurrency-mode-configuration[transaction concurrency mode configuration]. + +=== Cluster Connection Configuration + +Cluster connection configuration defines Apache Ignite node that `SpringTransactionManager` will use to access the cluster. +To do this, you can use the following approaches. + +[NOTE] +==== +Mixing of multiple approaches is illegal and results in an exception during manager startup. +==== + +[discrete] +=== 1.
