Question

我正在开发一个Spring Boot应用程序，我最近从Spring 3升级到Spring 4（spring-boot-starter-parent 1.3.5.RELEASE到1.4.6.RELEASE）。

我在src/main/resources/templates目录中有一个html模板（称为'test-template.html'），我一直用它来创建HTML电子邮件内容，使用Thymeleaf的TemplateEngine。（在升级到版本4之前，此工作正常。）

我目前遇到的问题是，在使用Maven构建时，在服务器上的WEB-INF内（或“目标”内的相关目录内）没有创建“模板”目录。结果，我得到以下内容：

java.io.FileNotFoundException：无法打开ServletContext资源[/WEB-INF/templates/test-template.html]

以下是Thymeleaf的配置类。（我使用手动配置，因为我只使用Thymeleaf进行电子邮件模板处理，因此不希望Spring Boot配置Thymeleaf视图解析器。但是，我在自动配置时会遇到相同的错误。）

@Configuration
public class ThymeleafConfig implements ApplicationContextAware {

    private static final Logger logger = LoggerFactory.getLogger(ThymeleafConfig.class);

    private ApplicationContext applicationContext;

    public void setApplicationContext(ApplicationContext applicationContext) {
        this.applicationContext = applicationContext;
    }

    @Bean
    public SpringTemplateEngine templateEngine() {
        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.setEnableSpringELCompiler(true);
        engine.setTemplateResolver(templateResolver());
        return engine;
    }

    private ITemplateResolver templateResolver() {
        SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
        resolver.setApplicationContext(applicationContext);
        resolver.setPrefix("/WEB-INF/templates/");
        resolver.setSuffix(".html");
        resolver.setTemplateMode(TemplateMode.HTML);
        return resolver;
    }

}

Answer 1

将/WEB-INF/templates/更改为classpath:/template/。在类路径上，在Web上下文路径上没有必要的意思。
