这是为什么呢？理论上前缀和后缀是可以自动帮我们补全的，为什么不行，也不知道。

WebMvcConfig:

package liangliang.bigdata.config;
    
    import org.springframework.beans.BeansException;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.ApplicationContextAware;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
    import org.thymeleaf.spring4.SpringTemplateEngine;
    import org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver;
    import org.thymeleaf.spring4.view.ThymeleafViewResolver;
    
    @Configuration
    //帮助我们获取spring的上下文
    public class WebMvcConfig extends WebMvcConfigurerAdapter implements ApplicationContextAware {
        //私有化一个类
        private ApplicationContext applicationContext;
        @Override
        public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
            this.applicationContext = applicationContext;
        }
        /**
         * 对模板资源进行解析
         * 模板资源解析器
         */
        @Bean
        //做一个前缀绑定，否则找不到路径
        @ConfigurationProperties(prefix = "spring.thymeleaf")
        public SpringResourceTemplateResolver templateResolver (){
            //实例化一个
            SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
            //设置spring的上下文
            templateResolver.setApplicationContext(this.applicationContext);
            return templateResolver;
        }
        /**
         * Thymeleaf标准方言解析器
         */
        @Bean
        public SpringTemplateEngine templateEngine(){
            SpringTemplateEngine templateEngine = new SpringTemplateEngine();
            //配置资源解析器的引擎
            templateEngine.setTemplateResolver(templateResolver());
            //设置支持EL表达式
            templateEngine.setEnableSpringELCompiler(true);
            return templateEngine;
        }
        /**
         * 视图解析器
         */
        @Bean
        public ThymeleafViewResolver viewResolver(){
            ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
            //配置Thymeleaf标准方言解析器
            viewResolver.setTemplateEngine(templateEngine());
            return viewResolver;
        }
    
    
    
    }

我发现上面补全themplates是假的，卧槽：

**application.properties:**

spring.profiles.active=dev
    
    #帮助我们在开发过程中执行的时候jpa我们执行的sql的语句
    spring.jpa.show-sql=true
    #hibernate 执行只进行sql的验证，不会对sql做一些增删改的操作的
    spring.jpa.hibernate.ddl-auto=validate
    
    #sql打印级别设置为debug
    logging.level.org.hibernate.SQL = debug
    
    #设置session会话存储的类型
    spring.session.store-type = hash_map
    #关闭http基本验证
    security.basic.enabled=false
    
    #thymeleaf
    spring.thymeleaf.mode=HTML
    #spring.thymeleaf.suffix=.html
    #spring.thymeleaf.prefix=classpath:/templates/

**解决办法，加上前缀和后缀就可以解决了！！！**
