String s1 = http://localhost:8080/api;
String s2 = http://localhost:8080/api/books/search/any?offset=5&limit=5;

// Remove identical part from s2
List<String> l = Lists.newArrayList(Splitter.on(s1).omitEmptyStrings().trimResults().split(s2));

String s3 = l.get(0); // => /books/search/any?offset=5&limit=5

// Split query string into name value
URI uri = URI.create(s3);
Map<String, String> split = Splitter.on('&').withKeyValueSeparator('=').split(uri.getQuery());
