The activity is not responding I have been working on developing an application which needed login and signup screen. My register activity is not working properly.

Basic Authentication in spring boot using spring-boot-starter-security is not working for latetst version of spring-boot-starter-parent I am trying to implement basic auth to my end points of my micro-services. So I used spring-boot-starter-security. But I have noticed that spring-boot-starter-security does not work with spring-boot-starter-parent-version > 2.0.3. So I switched to spring-boot-starter-parent-version > 1.5.2 where it was working perfectly for my reference project. Can any one help me with any other method for implementing basic auth with latest version of spring-boot-starter-parent? My problem now is some class where I have written my logic, which is implemented in the latest version, are not functional with the former version of spring boot-starter-parent. Especially where there are methods for reading time stamps. Here is my pom.xml for reference. <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/...

Then what can I take in, some sort of wrapper class? 2 Answers 2 @JustinPihony's answer is correct but it's incomplete. The isin function takes a repeated parameter for argument, so you'll need to pass it as so : isin scala> val df = sc.parallelize(Seq(1,2,3,4,5,6,7,8,9)).toDF("column") // df: org.apache.spark.sql.DataFrame = [column: int] scala> val sequence = Seq(1,2,3,4,5) // sequence: Seq[Int] = List(1, 2, 3, 4, 5...
