springboot如何返回html和jsp

ID:9631 / 打印

本篇文章给大家介绍一下springboot返回html和jsp的方法。有一定的参考价值，有需要的朋友可以参考一下，希望对大家有所帮助。

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）结构图如下

（4）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

三、加载css、js文件

放到static下
