How to replace characters at PathVariable in SpringBoot
问题
我尝试了几种方法，但未能解决。我正在寻找一种解决方案，可以在Spring Boot的Path Variable中替换特殊字符。
示例：
xyz.com/3233+23+232+323
我正在寻找一种可能的解决方案，其中Spring的@PathVariable将把字符串“323323232323”返回给我，不带 +号。
我知道我可以进行简单的字符串替换，但有数百个API，这将是困难的。
我正在寻找一些需要最小更改的东西。
英文:
I tried a couple of solutions but was unable to solve it. I looking for a solution where I can replace special characters in Path Variable in Spring Boot.
Example
xyz.com/3233+23+232+323
I am looking for a possible solution where Spring @PathVariable returns me the String "323323232323" without + sign.
I know I can do a simple String replace, but there are 100's of API's and it will be difficult to do that.
I am looking for something with minimal changes required.

一种方法，只需读取 @PathVariable 的值，然后应用正则表达式。
只需一行，示例：
@GetMapping("/read/{str}")
public String check(@PathVariable String str){
String modifiedStr = str.replaceAll("\\+", "");
return modifiedStr;
}
示例： http://localhost:8080/ticket-service/read/3233+23+232+323
输出： 323323232323
英文:
One way, just read the @PathVariable value, then apply a regular expression.
Just One line, Example:
@GetMapping("/read/{str}")
public String check(@PathVariable String str){
String modifiedStr = str.replaceAll("\\+", "");
return modifiedStr;
}
Sample: http://localhost:8080/ticket-service/read/3233+23+232+323
Output: 323323232323
