spring boot项目eclipse中启动访问jsp/html问题，这个问题困惑了小编好长时间，也在百度中看到了好多大牛的讲解，可是这始终是别人的，照搬过来不适合自己，然后我根据自己的项目，不断尝试，最终得到如下解决办法。

1.首先是需要一个视图解析工具类

	package com.asphalt;
	
	import org.springframework.context.annotation.Bean;
	import org.springframework.context.annotation.ComponentScan;
	import org.springframework.context.annotation.Configuration;
	import org.springframework.web.servlet.ViewResolver;
	import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
	import org.springframework.web.servlet.config.annotation.EnableWebMvc;
	import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
	import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
	import org.springframework.web.servlet.view.InternalResourceViewResolver;
	import org.thymeleaf.spring5.SpringTemplateEngine;
	import org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver;
	import org.thymeleaf.spring5.view.ThymeleafViewResolver;
	import org.thymeleaf.templateresolver.ITemplateResolver;
	
	@Configuration
	public class ViewResolverConfiguration {
	
    @Configuration//用来定义 DispatcherServlet 应用上下文中的 bean
    @EnableWebMvc
    @ComponentScan("com.asphalt.controller")
    public class WebConfig implements WebMvcConfigurer {
        @Bean
        public ViewResolver viewResolver() {
            InternalResourceViewResolver resolver = new InternalResourceViewResolver();
            resolver.setPrefix("/WEB-INF/vm/");
            resolver.setSuffix(".jsp");
            resolver.setViewNames("*");
            resolver.setOrder(2);
            return resolver;
        }

        @Bean
        public ITemplateResolver templateResolver() {
            SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
            templateResolver.setTemplateMode("HTML5");
            templateResolver.setPrefix("/WEB-INF/html/");
            templateResolver.setSuffix(".html");
            templateResolver.setCharacterEncoding("utf-8");
            templateResolver.setCacheable(false);
            return templateResolver;
        }

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

        @Bean
        public ThymeleafViewResolver viewResolverThymeLeaf() {
            ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
            viewResolver.setTemplateEngine(templateEngine());
            viewResolver.setCharacterEncoding("utf-8");
            viewResolver.setOrder(1);
            viewResolver.setViewNames(new String[]{"/*"});
            return viewResolver;
        }

        @Override
        public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
            configurer.enable();
        }

        @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) {
            registry.addResourceHandler("/img/**").addResourceLocations("/img/");
            registry.addResourceHandler("/css/**").addResourceLocations("/css/");
            registry.addResourceHandler("/js/**").addResourceLocations("/js/");
            registry.addResourceHandler("/static/**").addResourceLocations("/WEB-INF/" + "/static/");
        }
    }
}

注意：

1. ComponentScan配置的是你的controller所在的文件路径地址。 此视图解析类位于controller的上一级节点上。
2. jsp和html的路径问题（viewResolver(jsp配置) 和 templateResolver(配置html)/viewResolverThymeLeaf(配置html)）
3. 静态资源路径问题(addResourceHandlers() )
4. 这里的文件结构是我的项目文件结构
   

2 . pom.xml文件添加的配置

		<!-- jsp需要jar -->
		<!-- jstl标签 -->
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>jstl</artifactId>
		</dependency>
		<!--用于编译jsp -->
		<dependency>
			<groupId>org.apache.tomcat.embed</groupId>
			<artifactId>tomcat-embed-jasper</artifactId>
		</dependency>

这里的pom.xml注释讲解的很清楚了，我就不在描述
