# ExposedAutoConfiguration

@AutoConfiguration(after = [DataSourceAutoConfiguration::class])
@EnableTransactionManagement
open class ExposedAutoConfiguration(applicationContext: ApplicationContext)

Main configuration class for Exposed that can be automatically applied by Spring Boot.

This should be applied on a Spring configuration class using: `@ImportAutoConfiguration(ExposedAutoConfiguration::class)`

Note As part of the configuration, `@EnableTransactionManagement` is added without setting any attributes. This means that all attributes have their default values, including `mode = AdviceMode.PROXY` and `proxyTargetClass = false`. If the type of proxy mechanism is unexpected, the attributes can be set to the required values in a separate `@EnableTransactionManagement` on the main configuration class or in a configuration file using `spring.aop.proxy-target-class`.
