Java split and replace a string with value

Question

I have a following string which I have to split and replace the value on some condition

http://localhost:8080/api/upload/form/{uploadType}/{uploadName}

in which I have to replace the value only for {uploadType}/{uploadName} . I really don't know how to go about to replace them with value.

The strings which are in {uploadType}/{uploadName} can be of any type to replace.

I've tried something like the following :

package com.test.poc;

public class TestString {
public static void main(String[] args) throws ClassNotFoundException {
    String toBeFixed = "http://localhost:8080/api/upload/form/{uploadType}/{uploadName}"; 
    String[] toReplaceWith =toBeFixed.split("{");
for (String string : toReplaceWith) {
    System.out.println("string : "+string);
}   
}

}

but i get the following exception:

Exception in thread "main" java.util.regex.PatternSyntaxException: Illegal repetition
{
    at java.util.regex.Pattern.error(Pattern.java:1713)

EDIT :

this is the method i tried based on Sean Patrick Floyd answer

public String doPOSTPathVariable(String uri,List paramsList) throws IllegalArgumentException, IllegalAccessException, InstantiationException, Exception{
        String uriString="";
        UriComponents uriComponents = UriComponentsBuilder.fromUriString(uri).build();
        for (int j = 0; j<= paramsList.size(); j++) {
            System.out.println("path variable");
            MethodParams methodParams;
            methodParams =(MethodParams) paramsList.get(j);

            if(methodParams.isPrimitive() && methodParams.getDataType()=="boolean"){
                  uriString = uriComponents.expand(true).encode().toUriString();
            }
            if(methodParams.isPrimitive() && methodParams.getDataType()=="java.math.BigDecimal"){
                uriString = uriComponents.expand(123).encode().toUriString();
            }
            if(methodParams.isPrimitive() && methodParams.getDataType()=="java.lang.String"){
                uriString = uriComponents.expand("hexgen").encode().toUriString();
            }
       } 
        return uriString;
    }

but i get following exception :

java.lang.IllegalArgumentException: Not enough variable values available to expand 'uploadName'

Could some one help me on this please?

Answer 1

Perhaps the UriBuilder?

UriBuilder.fromPath("http://localhost:8080/api/upload/form/{uploadType}/{uploadName}").build("foo", "bar");

(Conveniently happens to use the exact formatting you are using)
