springboot项目整合jsp

技术2026-03-04 12

用的工具是eclipse的sts。前因：由于要springboot项目需要接入支付宝的接口，而支付宝的demo又是jsp文件，所以研究了一下如何在springboot中支持jsp文件。本文只适用于springboot+jsp，不支持springboot+jsp+html！！

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

首先在pom.xml文件中引入这2个依赖其次创建目录结构如图。具体为在main下new folder，把所有文件夹都new出来然后在webapp那里右键 build path–>use as source folder搞定！！或者在项目右键build path–>configure build path 点击add folder 打钩，完成！！！在application.yml中配置jsp视图解析器前缀后缀

#server server: port: 80 #HikariCp spring: mvc: view: prefix: /WEB-INF/jsp/ suffix: .jsp

application.properties（二选一）中则是

spring.mvc.view.prefix=/WEB-INF/jsp/ spring.mvc.view.suffix=.jsp

jsp文件夹下创建show1.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html> <html> <head> <meta charset="ISO-8859-1"> <title>Insert title here</title> </head> <body> <h1>spring to jsp but conflict with html</h1> </body> </html>

创建控制层

@Controller public class FirstController { @RequestMapping("/show") @ResponseBody public String show() { return "hello world!"; } @RequestMapping("/show1") public String show1() { //return "/WEB-INF/jsp/show1.jsp"; return "show1"; } }

localhost/show 就可以访问jsp了再次提醒：只适用于springboot+jsp，不适合springboot+jsp+html 因为在html与jsp共同存在下，系统默认jsp访问的是html 要实现springboot+jsp+html目前可实现方法 1 配置双视图解析器
