    Are you using the 
    kotlin-spring
    plugin?

    : you should: 1. either use the 
    open
    keyword on your class and 
    @Bean
    methods 2. use the 
    kotlin-spring
    plugin that will do that at build time

    Make sure you rebuild the project after applying the plugin, last time I checked IntelliJ does not recognize that it needs to invalidate the build artifacts.

    Hi! I am trying to use spring-aop with kotlin but seems like it never goes in to my aop function. (I added kapt as plugin to my gradle) any ideas?

    @sdeleuze kotlin 1.2.20 seems to changed the location of 
    ReflectKotlinClass
    . with a simple spring boot project (spring boot 2.0.0.M7; gradle, kotlin; web, jpa, h2), when i change the kotlin version to 1.2.20, i get following exception:

    @lex It depends what you mean by "fixed". I plan to add 
    kotlin-stdlib-jdk7
    and 
    kotlin-stdlib-jdk8
    to Boot managed dependencies and use these new dependencies instead of jre ones on 
    <http://start.spring.io|start.spring.io>
    .

    To override Kotlin version with Boot you should just write :
  • s

    sdeleuze

    01/18/2018, 9:02 AM
    Copy code
    buildscript {
	ext {
		kotlinVersion = '1.2.20'
		springBootVersion = ...
	}
  • s

    sdeleuze

    01/18/2018, 9:02 AM
    Since Kotlin is part of Boot managed dependencies
