The Spring Framework offers an array of robust tools for web developers, and one such utility is the UriComponentsBuilder. This tool provides an elegant and fluent API for building and manipulating URIs. This article offers a deep dive into various methods and applications of UriComponentsBuilder, backed by practical examples.

Understanding UriComponentsBuilder

UriComponentsBuilder is a part of the org.springframework.web.util package. Its primary function is to assist developers in creating and manipulating URI structures seamlessly. Leveraging this tool ensures that the resulting URI adheres to the encoding rules, making the process error-free.

Key Features:

Why Should Developers Should Care About UriComponentsBuilder?

In the digital realm, where applications constantly interact through the web, ensuring accurate and seamless URI construction and manipulation becomes paramount. UriComponentsBuilder stands at the forefront of this necessity, offering solutions that every web developer should be acquainted with. Here’s why:

Precision and Standardization in URI Creation

Crafting URIs manually can be prone to errors, especially when dealing with dynamic content and parameters. UriComponentsBuilder offers a methodological approach, ensuring that every segment of the URI is correctly placed and valid, eliminating the chances of malformed URIs.

Automatic Encoding and Escaping

Handling special characters in URIs is a common challenge. With UriComponentsBuilder, developers can sidestep this hurdle as it automatically encodes special characters, ensuring that the URI remains consistent and adheres to web standards.

Enhanced Readability

Building URIs through concatenation can quickly become cluttered and hard to decipher, particularly in complex applications. UriComponentsBuilder structures the URI creation process, promoting cleaner code that’s easier to understand and maintain.

Streamlined Templating

URI templates are a powerful tool for creating dynamic URIs based on variable substitutions. With methods like buildAndExpand(), developers can effortlessly use templates, making it easier to generate context-specific URIs without cumbersome string manipulations.

Fluent API Design

The builder pattern, embraced by UriComponentsBuilder, facilitates a fluent, chainable API. This design allows developers to construct URIs in a linear and intuitive manner, boosting productivity and minimizing cognitive load.

Seamless Integration with Spring

For projects that already use the Spring ecosystem, leveraging UriComponentsBuilder ensures seamless compatibility. It smoothly integrates with other parts of the Spring Web module, aiding in tasks like MVC routing, RESTful service construction, and more.


One of the often-overlooked advantages is the ease of testing. By using UriComponentsBuilder, developers can break down URI construction into logical segments, making unit testing more straightforward. It offers a deterministic way to create URIs, ensuring that any changes or regressions can be quickly identified through tests.

Future-Proofing and Scalability

Given the evolving nature of web standards and technologies, relying on a tool that’s actively maintained and updated, like UriComponentsBuilder, assures developers that their applications remain scalable and in line with modern practices.

In essence, UriComponentsBuilder isn’t just a convenience—it’s a strategic tool. It encapsulates best practices for URI construction and offers a suite of functionalities that bolsters code quality, application robustness, and developer efficiency. As web interactions continue to grow in complexity, tools like these become indispensable in a developer’s toolkit.

Fluent API

A Fluent API is a design approach in object-oriented software development that focuses on producing more readable code by providing method chaining capabilities. This design pattern allows function calls to be chained together, forming a single flowing expression that describes a particular operation or series of operations. It’s termed “fluent” because the resultant code can be read smoothly, almost like a sentence in natural language.

Fluent APIs are especially beneficial when configuring or setting up objects, as they allow for a clear, linear progression of method calls. They reduce cognitive load, enhance code readability, and can lead to more concise code.

Fluent API Design with UriComponentsBuilder

One of the distinctive features of UriComponentsBuilder is its adoption of the builder pattern, which results in a fluent API design. Let’s examine this with a concrete example.

Imagine you’re constructing a URI for a RESTful service endpoint that fetches details about a book based on its ISBN. The book details are available in various formats, such as JSON, XML, and HTML. You want the constructed URI to be flexible enough to accommodate different book ISBNs and response formats.

Using UriComponentsBuilder, you can achieve this with a clear, linear flow:

public class BookServiceUriConstructor {

    private static final String BASE_URL = "https://www.bookapi.com";

    public String constructBookDetailUri(String isbn, String format) {
        return UriComponentsBuilder.fromHttpUrl(BASE_URL)
            .queryParam("format", format)
    public static void main(String[] args) {
        BookServiceUriConstructor constructor = new BookServiceUriConstructor();
        String jsonUri = constructor.constructBookDetailUri("1234567890", "json");
        System.out.println(jsonUri);  // Outputs: https://www.bookapi.com/api/book/1234567890?format=json
        String xmlUri = constructor.constructBookDetailUri("0987654321", "xml");
        System.out.println(xmlUri);  // Outputs: https://www.bookapi.com/api/book/0987654321?format=xml

In this example, the fluent design of the API allows for a seamless chaining of methods. The chainable approach reduces the need for intermediate variables or disjointed operations. The result is a smooth, logical progression from the start to the end of the URI construction process, exemplifying the strengths of a fluent API design in action.

Built-In Support for Encoding and Special Characters

A prominent feature of the UriComponentsBuilder is its built-in support for URI encoding, ensuring that all special characters in the URI components are correctly escaped:

String specialCharacterUri = UriComponentsBuilder.fromHttpUrl("https://www.sample.com/search")
    .queryParam("query", "Spring Boot & Framework")

System.out.println(specialCharacterUri);  // Yields: https://www.sample.com/search?query=Spring%20Boot%20%26%20Framework

In the example above, the ampersand (&) and spaces in the query parameter are correctly escaped to %26 and %20 respectively. This ensures that the URI remains valid and interpretable by web servers and clients.

Moreover, this automatic encoding saves developers from manually escaping characters, preserving the URI’s integrity and readability.

Testability of UriComponentsBuilder

One of the most valuable aspects of UriComponentsBuilder is its ability to enhance testability in URI construction. Let’s delve into this with an example.

Suppose you have a service that constructs URIs for accessing user profiles in a web application:

public class UserProfileUriService {

    public String constructUserProfileUri(String userId) {
        return UriComponentsBuilder.fromHttpUrl("https://www.example.com")
            .queryParam("details", "full")

To ensure that the constructUserProfileUri method is working as expected, you’d want to write a unit test. Given the methodological approach of UriComponentsBuilder, this becomes straightforward:

import static org.assertj.core.api.Assertions.assertThat;

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;

public class UserProfileUriServiceTest {

    private UserProfileUriService userProfileUriService;

    public void setup() {
        userProfileUriService = new UserProfileUriService();

    public void testConstructUserProfileUri() {
        String userId = "12345";
        String expectedUri = "https://www.example.com/api/users/12345?details=full";
        String actualUri = userProfileUriService.constructUserProfileUri(userId);

The predictability of UriComponentsBuilder means that you can confidently assert the expected outcome in your tests. Moreover, should the URI construction logic change in the future, adjusting and extending the tests becomes a simpler task.

In essence, the clear segmentation of URI components facilitated by UriComponentsBuilder not only improves code readability but also enhances test clarity and reliability.

Dive into Practical Demonstrations

Constructing a Basic URI

For a head start, let’s craft a simple URI:

import org.springframework.web.util.UriComponentsBuilder;

public class BasicUriExample {
    public static void main(String[] args) {
        String uriOutput = UriComponentsBuilder.newInstance()
        System.out.println(uriOutput); // Displays: https://www.samplewebsite.com/api/books

This example establishes the foundation for creating a URI using UriComponentsBuilder.

Manipulating Path and Path Segments

Modifying paths or integrating segments into the URI is a frequent requirement. Here’s how:

String uriOutput = UriComponentsBuilder.newInstance()
    .pathSegment("books", "fiction")
System.out.println(uriOutput); // Displays: https://www.samplewebsite.com/api/books/fiction

Introducing Query Parameters

Query parameters play a vital role in refining search criteria. Here’s an illustration:

String uriOutput = UriComponentsBuilder.newInstance()
    .queryParam("author", "Orwell")
    .queryParam("publishedYear", 1949)
System.out.println(uriOutput); // Displays: https://www.samplewebsite.com/api/books?author=Orwell&publishedYear=1949

Leveraging URI Templates

Dynamic URI generation becomes effortless with placeholders. Here’s a demonstration:

String uriOutput = UriComponentsBuilder.newInstance()
System.out.println(uriOutput); // Displays: https://www.samplewebsite.com/api/books/dystopian

Modifying Query Parameters

Replacing existing query parameters is a breeze:

String uriOutput = UriComponentsBuilder.newInstance()
    .queryParam("genre", "fantasy")
    .replaceQueryParam("genre", "science-fiction")
System.out.println(uriOutput); // Displays: https://www.samplewebsite.com/api/books?genre=science-fiction

Integrating Multiple Query Parameters

Combining parameters from different parts of an application:

UriComponentsBuilder primaryBuilder = UriComponentsBuilder.fromUriString("https://samplewebsite.com/api/products");
primaryBuilder.queryParam("type", "gadgets");
UriComponentsBuilder secondaryBuilder = UriComponentsBuilder.fromUriString("");
secondaryBuilder.queryParam("brand", "techcorp").queryParam("availability", "in-stock");
System.out.println("Final URI: " + primaryBuilder.toUriString());


Final URI: https://samplewebsite.com/api/products?type=gadgets&brand=techcorp&availability=in-stock

Use Case: HATEOAS URL Generation Using UriComponentsBuilder

HATEOAS (Hypermedia as the Engine of Application State) is a principle within the REST architectural style that emphasizes the importance of including hypermedia controls (like URLs) within the response payload. It guides the client about the subsequent possible interactions they can perform with the API.

A key benefit of HATEOAS is that it allows the client to navigate the API dynamically, making the API self-descriptive. The client doesn’t need to hard-code URI patterns; instead, they rely on the server to provide the necessary URIs.

UriComponentsBuilder plays an instrumental role in implementing HATEOAS, especially in the context of a Spring Boot application. The builder can dynamically generate URLs based on the current request, thus aiding in the creation of HATEOAS-compliant responses.

Example: Creating a HATEOAS Response for a Book Resource

Suppose you have a REST API that exposes a book resource, and you want to provide the client with links to read a specific book, update its information, or delete it. Using UriComponentsBuilder, you can generate these URLs dynamically:

public class BookController {

    public ResponseEntity<BookResource> getBook(@PathVariable Long id, UriComponentsBuilder builder) {
        // Fetch the book from the database (omitted for brevity)
        Book book = findBookById(id);

        // Create HATEOAS links
        UriComponents readLink = builder.cloneBuilder()
        UriComponents updateLink = builder.cloneBuilder()
            .pathSegment("{id}", "update")
        UriComponents deleteLink = builder.cloneBuilder()
            .pathSegment("{id}", "delete")

        // Create the HATEOAS resource and add links
        BookResource bookResource = new BookResource(book);
        bookResource.addLink("self", readLink.toUriString());
        bookResource.addLink("update", updateLink.toUriString());
        bookResource.addLink("delete", deleteLink.toUriString());

        return ResponseEntity.ok(bookResource);

In this example:

This dynamic URL generation approach ensures that even if the underlying URI structure changes, the HATEOAS links returned to the client will always be accurate, making the API more maintainable and robust.

In Conclusion

UriComponentsBuilder is undeniably a game-changer for developers working with the Spring Framework. It simplifies the process of crafting and manipulating URIs while ensuring they remain compliant with encoding norms. By integrating the examples provided, developers can efficiently manage URIs in their Spring-based projects, streamlining their workflows.
