In this post under Spring SpEL, I will show with example how to use ternary operator in SpEL.
Below is the main class for your reference.
Main class
1 package spel.package18;
2
3 import org.springframework.beans.factory.annotation.Value;
4 import org.springframework.context.ApplicationContext;
5 import org.springframework.context.annotation.AnnotationConfigApplicationContext;
6 import org.springframework.context.annotation.Bean;
7 import org.springframework.context.annotation.Configuration;
8
9 import java.util.Arrays;
10 import java.util.List;
11
12 @Configuration
13 public class Example18 {
14 @Value("#{(integerList.size() % 2) == 0 ? true : false}")
15 public boolean evenPopulated;
16
17 @Bean
18 public List<Integer> integerList() {
19 List<Integer> list = Arrays.asList(1, 2, 3, 4);
20 return list;
21 }
22
23 public static void main(String[] args) {
24 ApplicationContext applicationContext = new AnnotationConfigApplicationContext(Example18.class);
25 Example18 example5 = applicationContext.getBean(Example18.class);
26 System.out.println(example5.evenPopulated);
27 }
28 }
In the above code, at line 14 we are using ternary operator in the SpEL expression.
In this way we can use ternary operator in SpEL
