这篇文章主要介绍springboot如何返回html和jsp,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
springboot是什么
springboot一种全新的编程规范,其设计目的是用来简化新Spring应用的初始搭建以及开发过程,SpringBoot也是一个服务于框架的框架,服务范围是简化配置文件。
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><h3>Hello World!</h3></body></html>
(4)controller代码如下
package springboot.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic 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
@Beanpublic 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;@Controllerpublic 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
