一、返回html

（1）添加maven依赖

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

（2）thymeleaf模板默认寻找resources下，templates文件夹放html页面，static文件夹放css及js

（3）引入js，需要使用如下格式

<html lang="en" xmlns:th="http://www.thymeleaf.org">
    <script type="text/javascript" th:src="@{/js/jquery/jquery.min.js}"></script>
    <script type="text/javascript" th:src="@{/js/jquery/jquery.easyui.min.1-7-5.js}"></script>
    <script type="text/javascript" th:src="@{/js/jquery/easyui-lang-zh_CN.js}"></script>
    <script type="text/javascript" th:src="@{/js/index.js}"></script>
    <body>
    <h2>Hello World!</h2>
    </body>
    </html>

（4）controller代码如下

package springboot.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class HtmlController {
        @RequestMapping("/show")
        public String show() {
            return "aaa";
        }
    }

二、返回jsp

（1）添加jsp的maven依赖

<dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
    </dependency>

注：返回jsp需要把spring-boot-starter-thymeleaf注释掉

（2）在controller里添加寻找jsp页面的视图解析器

@Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

（3）controller代码如下

package springboot.controller;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.view.InternalResourceViewResolver;
    
    @Controller
    public class JspController {
        @RequestMapping("/test")
        public String index() {
            return "home";
        }
        @Bean
        public InternalResourceViewResolver viewResolver() {
            InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
            viewResolver.setPrefix("/WEB-INF/");
            viewResolver.setSuffix(".jsp");
            return viewResolver;
        }
    }

注：返回html和jsp时使用@Controller注解
