The steps for encapsulating Spring Boot utility class are as follows:<\/p>\n

    \n
  1. Create a Java class named SpringBootUtils (or any other name as needed) and declare it as a utility class using the public final class keyword.<\/li>\n
  2. Include a private constructor to prevent the class from being instantiated.<\/li>\n
  3. Add static methods in this class that can perform common Spring Boot operations, such as retrieving environment variables and getting application configuration properties.<\/li>\n
  4. Annotations can be added to explain the purpose, parameters, and return values of each method as needed.<\/li>\n
  5. To better organize the code, one can group methods within a class based on their functions or relevance, and organize them using static inner classes or other methods.<\/li>\n<\/ol>\n

    Below is an example code for the SpringBootUtils utility class:<\/p>\n
