WebClient.builder() VS WebClient.create()

The choice between WebClient.builder() and WebClient.create() depends on the level of customization required for the WebClient instance.

 

• WebClient.create():

  This static factory method provides a quick way to create a WebClient instance with default settings. It can also accept a base URL as an argument, simplifying the creation of clients for a specific endpoint. Use this when minimal configuration is needed.
• WebClient.builder():

  This method returns a WebClient.Builder instance, offering extensive customization options. It allows for configuring various aspects of the WebClient, such as:

  • baseUrl(): Setting a base URL for all requests made by this client.
  • defaultHeader(): Adding default headers to all requests.
  • filter(): Applying custom filters for request/response modification.
  • clientConnector(): Customizing the underlying HTTP client (e.g., configuring timeouts, SSL).
  • codecs(): Adjusting codec settings, such as maxInMemorySize.

Conclusion:

 

• Use WebClient.create() for simple scenarios where default configurations suffice or only a base URL is required.
• Use WebClient.builder() when fine-grained control over the WebClient's behavior is necessary, enabling advanced configurations like timeouts, custom headers, or client connectors.
