代碼如下：

@RestControllerpublic class DataController { @RequestMapping('/d') public String test(Model model){Bean b = new Bean();b.setAge(18);b.setName('李四');model.addAttribute('bean',b);return 'index'; }}

請問是有什么依賴或者語句錯誤嗎？

問題解答

你應該用@Controller而不是@RestController

pom.xml中配置依賴了嗎？

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId></dependency>回答3：

1、確認一些依賴的配置是否完整2、報錯中有一句是2017-06-12 13:12:49.468 WARN 6804 --- [ main] .t.AbstractTemplateResolverConfiguration : Cannot find template location: /templates/ (please add some templates or check your Thymeleaf configuration)，不知道有沒有關系3、看看會不會是依賴之間的版本有問題

我也是剛學，希望對你有幫助
