Example 1 with HandlerExceptionResolver

use of org.springframework.web.servlet.HandlerExceptionResolver in project spring-boot by spring-projects.

the class WebMvcAutoConfigurationTests method testLogResolvedExceptionCustomization.

private void testLogResolvedExceptionCustomization(final boolean expected) {
    HandlerExceptionResolver exceptionResolver = this.context.getBean(HandlerExceptionResolver.class);
    assertThat(exceptionResolver).isInstanceOf(HandlerExceptionResolverComposite.class);
    List<HandlerExceptionResolver> delegates = ((HandlerExceptionResolverComposite) exceptionResolver).getExceptionResolvers();

Example 2 with HandlerExceptionResolver

use of org.springframework.web.servlet.HandlerExceptionResolver in project spring-framework by spring-projects.

the class WebMvcConfigurationSupport method handlerExceptionResolver.

/**
	 * Returns a {@link HandlerExceptionResolverComposite} containing a list
	 * of exception resolvers obtained either through
	 * {@link #configureHandlerExceptionResolvers(List)} or through
	 * {@link #addDefaultHandlerExceptionResolvers(List)}.
	 * <p><strong>Note:</strong> This method cannot be made final due to CGLib
	 * constraints. Rather than overriding it, consider overriding
	 * {@link #configureHandlerExceptionResolvers(List)}, which allows
	 * providing a list of resolvers.
