+[[changing-the-order]]
+== Specifying Order
+
+As already noted, there is a Spring AOP method interceptor for each annotation, and each of these has a location in the Spring AOP advisor chain.
+
+Namely, the `@PreFilter` method interceptor's order is 100, ``@PreAuthorize``'s is 200, and so on.
+
+The reason this is important to note is that there are other AOP-based annotations like `@EnableTransactionManagement` that have an order of `Integer.MAX_VALUE`.
+In other words, they are located at the end of the advisor chain by default.
+
+At times, it can be valuable to have other advice execute before Spring Security.
+For example, if you have a method annotated with `@Transactional` and `@PostAuthorize`, you might want the transaction to still be open when `@PostAuthorize` runs so that an `AccessDeniedException` will cause a rollback.
+
+To get `@EnableTransactionManagement` to open a transaction before method authorization advice runs, you can set ``@EnableTransactionManagement``'s order like so:
+
+====
+.Java
+[source,java,role="primary"]
+----
+@EnableTransactionManagement(order = 0)
+----
+
+.Kotlin
+[source,kotlin,role="secondary"]
+----
+@EnableTransactionManagement(order = 0)
+----
+
+.Xml
+[source,xml,role="secondary"]
+----
+<tx:annotation-driven ref="txManager" order="0"/>
+----
+====
+
+Since the earliest method interceptor (`@PreFilter`) is set to an order of 100, a setting of zero means that the transaction advice will run before all Spring Security advice.
