preface

I believe you may have encountered this situation. We often use string templates when developing requirements similar to station letters, such as

The ${name} inside can be replaced by the user's user name.

The following is a simple implementation of this function using regular expressions:

The key value pairs are stored in the map, then the collection of key value pairs is obtained, and the collection is traversed to render the string

Example test:

Two variables need to be replaced, name and six. The corresponding values are Java and 6 respectively. At the same time, name is called twice.

result:

summary
