【问题描述】：
我已经阅读过类似的问题，但我没有找到解决方案。我对 Thymeleaf 有一些问题，因为这段代码与 jsp 一起工作。但是使用 Thymeleaf 它找不到我的查看页面。
这是一个 WebConfig 类
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = " namePackage.controller;")
public class WebConfig implements WebMvcConfigurer
@Autowired
private ApplicationContext applicationContext;
/*
* STEP 1 - Create SpringResourceTemplateResolver
* */
@Bean
public SpringResourceTemplateResolver templateResolver() {
SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
templateResolver.setApplicationContext(applicationContext);
templateResolver.setPrefix("src/main/webapp/WEB-INF/views/");
templateResolver.setSuffix(".html");
return templateResolver;
}
/*
* STEP 2 - Create SpringTemplateEngine
* */
@Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.setTemplateResolver(templateResolver());
templateEngine.setEnableSpringELCompiler(true);
return templateEngine;
}
/*
* STEP 3 - Register ThymeleafViewResolver
* */
public void configureViewResolvers(ViewResolverRegistry registry) {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
registry.viewResolver(resolver);
}
}
这是一个简单的控制器
@Controller
@RequestMapping("/")
public class BenvenutoController {
@GetMapping("/ciao")
public String ciao(Model model) {
model.addAttribute("mex", "Hello");
return "welcome";
}
}
这是 html 页面（名为“欢迎”的视图）
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Hi</title>
</head>
<body>
<div >
<h1>Hello</h1>
<p th:text="${mex}"></p>
</div>
</body>
</html>org.springframework.web.util.NestedServletException：处理程序调度失败；嵌套异常是 java.lang.Error：未解决的编译问题： 类型Model中的addAllAttributes(Collection>)方法不适用于参数(String, String)
所以它找不到我的视图页面，但它的路径是正确的。 我正在使用 Spring Tool Suite，就像一个 idee。
所有堆栈跟踪错误：

【问题讨论】：
-
src目录不是有效的运行时位置。试试templateResolver.setPrefix("/WEB-INF/views/");，另见FileNotFoundException while using multiple folders for Thymeleaf 3 template resolver。 -
@andrewjames 谢谢。我解决问题。如果我这样写，Java 找不到文件：setPrefinx("/WEB-INF/**)，但如果我这样写，java 会找到文件：setPrefix("WEB-INF/**)跨度>

好消息。您可以将其写为答案，以供将来的访问者使用。您也可以接受自己的答案。

@andrewjames 您可以在 2 天内接受自己的答案
