如何使用UricomponentsBuilder替换程体

Question

我有一个URL，如下所示，

http://example.com/{id}

我想将其更改为

http://example.com/12

我的编码，

url= "http://example.com/{id}";

UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(url);
builder.pathSegment("{id}", "12");
UriComponents uriComponents = builder.build().encode();
URI uri = uriComponents.toUri();

System.out.println(uri);

因为它在其下方已将输出

http://example.com/%7Bid%7D/id/12

不确定是什么是使用UricomponentsBuilder的正确方法

Answer 1

要用一个实际值替换占位符，您需要用参数调用构建

    String url = "http://example.com/{id}";

    UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(url);
    URI uri = builder.build("12");

    System.out.println(uri);
