With controller:

@RestController
public class PredictionApiController {

    private static final Logger log = LoggerFactory
            .getLogger(PredictionApiController.class);

    @Inject
    private EventClient eventClient;
    @Inject
    private EngineClient engine;

    @RequestMapping(method=RequestMethod.POST, value="/recipe_recommendations/randomize")
    public ResponseEntity<String> randomizeRecipeRecommendations(@RequestParam("personId") String personId) 
            throws JsonProcessingException, IOException, ExecutionException, InterruptedException {
        Preconditions.checkArgument(!Strings.isNullOrEmpty(personId), "personId is required");
        final JsonNode recipesJson = new ObjectMapper().readTree(PredictionApiController.class.getResource("/recipes.json"));
        final ImmutableList<String> recipeIds = FluentIterable.from(recipesJson.get("recipes")).transform(it -> it.get("id").asText()).toList();
        for (int i = 0; i < 10; i++) {
            final String recipeId = recipeIds.get(RandomUtils.nextInt(0, recipeIds.size()));
            log.debug("{} liking recipe {}", personId, recipeId);
            eventClient.setUser(personId, ImmutableMap.of());
            eventClient.setItem("Recipe_" + recipeId, ImmutableMap.of("pio_itypes", "Recipe"));
            final String userActionItem = eventClient.userActionItem("like", personId, "Recipe_" + recipeId, ImmutableMap.of());
            log.debug("userActionItem: {}", userActionItem);
        }
        return new ResponseEntity<>("randomized", HttpStatus.CREATED);
    }

}

And unit test:

@RunWith(SpringJUnit4ClassRunner.class)
//@EnableAutoConfiguration(exclude=CrshAutoConfiguration.class) //http://stackoverflow.com/questions/26698071/how-to-exclude-autoconfiguration-classes-in-spring-boot-junit-tests
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
public class PredictionApiControllerTest {

    private static final Logger log = LoggerFactory
            .getLogger(PredictionApiControllerTest.class);

    @Inject
    WebApplicationContext wac;

    MockMvc mockMvc;

    @Before
    public void setUp() throws Exception {
        mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }

    @Test
    public void randomizeRecipeRecommendationsHendy() throws Exception {
        ResultActions actions = mockMvc.perform(post("/recipe_recommendations/randomize")
                .param("personId", "hendy")
                //.header("Host", "tuneeca")
                .accept(MediaTypes.HAL_JSON));
        MvcResult result = actions.andReturn();
        log.info("Status: {} {}", result.getResponse().getStatus(), result.getResponse().getErrorMessage());
        log.info("Type: {}", result.getResponse().getContentType());
        log.info("Content: {}", result.getResponse().getContentAsString());
        actions.andExpect(status().isCreated());
    }

}

ThymeleafAutoConfiguration throws IllegalStateException below, even though the method returns ResponseEntity so Thymeleaf isn't required at all in this case.

I believe that the ThymeleafAutoConfiguration kicks in before MVC annotations are evaluated so it's not aware of the ResponseEntity return type. It's simply say you have thymeleaf on your classpath but you don't have a /templates folder.

You can set spring.thymeleaf.check-template-location=false in your application.properties if you don't want that check.

Add check-template-location properties to appendix

Some were missing, some were named incorrectly.

I notices that we were missing that key from the documentation so I've updated that.

Thanks for the doc update!

I've to add that this error didn't happen if the method returns an object (which will be formatted as JSON) even when templates/ didn't exist.

Anyway as you say this is intended behavior.

I changed my application.properties file only like spring.thymeleaf.check-template-location=false and i customised my TemplateConfiguration class is :

@Configuration
public class TemplateConfiguration {

    @Bean
    public ServletContextTemplateResolver servletContextTemplateResolver() {
        ServletContextTemplateResolver servletContextTemplateResolver =
                new ServletContextTemplateResolver();
        servletContextTemplateResolver.setPrefix("classpath:/views");
        servletContextTemplateResolver.setSuffix(".html");
        servletContextTemplateResolver.setTemplateMode("HTML5");
        return servletContextTemplateResolver;
    }

    @Bean
    public SpringTemplateEngine springTemplateEngine() {
        SpringTemplateEngine springTemplateEngine = new SpringTemplateEngine();
        springTemplateEngine.setTemplateResolver(servletContextTemplateResolver());
        return springTemplateEngine;
    }

    @Bean
    public ThymeleafViewResolver thymeleafViewResolver() {
        ThymeleafViewResolver thymeleafViewResolver =
                new ThymeleafViewResolver();
        thymeleafViewResolver.setTemplateEngine(springTemplateEngine());
        thymeleafViewResolver.setOrder(1);
        return thymeleafViewResolver;
    }
}

i still have an error when i send a new request and also i have home.html file in views file:

@semihokanpehlivan The property you have configured disables a check for their being a folder named templates on the classpath. That check happens during startup. The failure you're seeing is at runtime so, as you've observed, the property won't have any effect.

This issue's closed and, from the information you've provided, it's impossible to tell if you've found a bug or your problem's due to user error. I'd recommend posting a question of Stack Overflow with a minimal, complete, verifiable example of the problem. We monitor the spring-boot tag regularly and can always open another issue if it turns out that there is a problem in Boot.
