Context paths
You can now configure the context path by calling app.contextPath("/context-path")
.
Any requests made below the context path will result in a 404. For example:
- Java
- Kotlin
Javalin app = Javalin.create()
.contextPath("/my-path")
.enabledStaticFiles("public")
.port(1234)
.start()
app.get("/", ctx -> ctx.result("Hello, World"));
val app = Javalin.create().apply {
contextPath("/my-path")
enabledStaticFiles("public")
port(1234)
}.start()
app.get("/") { ctx -> ctx.result("Hello, World") }
GET localhost:1234/ // 404
GET localhost:1234/my-path // 200 (Hello, World)
GET localhost:1234/my-path/ // 200 (Hello, World)
GET localhost:1234/script.js // 404
GET localhost:1234/my-path/script.js // 200 (if there is a script.js file in your /public folder)
Any argument to contextPath()
will be normalized to the form /path
(slash, path, no-slash)
@NotNull annotations
All the Java API’s have had @NotNull
added to their method signatures, which should provide better IDE support
when programming in Kotlin.
Simple safety refactoring
- Always check if response is committed before trying to write to it
- Wrap
doHandle()
in try-catch
