Java Code Examples for org.springframework.core.Conventions

The following examples show how to use org.springframework.core.Conventions. These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

Example 1

			"cannot both be declared with an async type wrapper. " +
			"Either declare the @ModelAttribute without an async wrapper type or " +
			"handle a WebExchangeBindException error signal through the async type.");
