In fact, APISIX uses [ngx.escape_uri](https://github.com/openresty/lua-nginx-module#ngxescape_uri) to escape uri, this way the + is translated into a space, I hope this is useful to you: https://www.cnblogs.com/zhengxl5566/p/10783422.html

+ apisix is %20 but in java is %2B
space apisix is %20 but in java is +
! apisix is ! but in java is %21
# apisix is %24 but in java is %23
% apisix is % but in java is %25
( apisix is ( but in java is %28
')' apisix is ) but in java is %29

I don't thin use replace is good idea

[liangliang4ward]

may be like this
String value = URLEncoder.encode(Optional.ofNullable(param.getValue()).orElse(""), "utf-8")
.replaceAll("\%2B","%20")
.replaceAll("\+","%20")
.replaceAll("\%21","!")
.replaceAll("\%27","'")
.replaceAll("\%28","(")
.replaceAll("\%29",")")
.replaceAll("\%7E","~")
.replaceAll("\%25","%")
;

It's barely okay. I think you could look for some generic class libraries, like guava.
