ScriptTemplateView which supports JSR-223 to render templates by using script engines. By leveraging scripting-jsr223 dependencies, it is possible to use such feature to render Kotlin- based templates with interpolated String. build.gradle.kts dependencies { runtime("org.jetbrains.kotlin:kotlin-scripting-jsr223:${kotlinVersion}") } Configuration is usually done with ScriptTemplateConfigurer and Sc inject the resulting objects. Spring’s scripting support primarily targets Groovy and BeanShell. Beyond those specifically supported languages, the JSR-223 scripting mechanism is supported for integration

hasn’t even yet introduced more advanced notions such as profile segmentation or Groovy action scripting. The system is capable of much more, for example by directly using its actions to integrate with $MY_KARAF_HOME/etc/unomi.custom.system.properties file 4.8. SCRIPTING SECURITY 4.8.1. MULTI-LAYER SCRIPTING FILTERING SYSTEM The scripting security system is multi-layered. For requests coming in through endpoint are first sanitized, meaning that any scripting directly injected is removed. However, as conditions can use sub conditions that include scripting, only the first directly injected layer of scripts
