springboot以其高效的開發效率越來越多的用在中小項目的開發，並且在分布式開發中的使用也很廣泛，springboot官方推薦的前端架構卻是thymeleaf,並且預設不支援jsp，而大部分java開發人員最熟悉的前端開發工具卻是jsp，自己在工作中就遇到這樣的情況，因此在網上找一些整合的demo，但是依然踩了很多坑，記錄下來以供學習。
代碼及配置如下：
1、pom.xml，這個是本人整合中遇到的最大的坑，主要是spring-boot-starter-parent的版本，自己先去官網查，官方文檔給的是2.0.3，然而試了下視圖解析器根本不起作用，然後又試了1.3.5和1.5.2，這兩個版本主要是SpringBootServletInitializer類的包位置變了，重新導一下包之後項目正常運行了，也能訪問到頁面，最後又試了下2.0.1版本，SpringBootServletInitializer類位置一樣，所有配置不變，項目就正常了，個人也不知道最新的springboot版本2.0.3為什麼不可以，所以推薦後續整合jsp的同學使用2.0.1版本。

2、SpringbootJspApplication
package com.example.demo;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.builder.SpringApplicationBuilder;import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;@SpringBootApplicationpublic class SpringbootJspApplication extends SpringBootServletInitializer{@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder application) {return application.sources(SpringbootJspApplication.class);}public static void main(String[] args) {SpringApplication.run(SpringbootJspApplication.class, args);}}
3、IndexController
package com.example.demo;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;@Controllerpublic class IndexController {@RequestMapping(value="/index",method=RequestMethod.GET)public String index() {return "index";}}
4、application.properties
spring.mvc.view.prefix= /WEB-INF/jsp/spring.mvc.view.suffix= .jsp
5、在main目錄下建立webapp/WEB-INF/jsp目錄，添加index.jsp
<!DOCTYPE html><%@page contentType="text/html; charset=UTF-8" language="java"%><html lang="en"><head><title>title</title></head><body>this is index jsp</body></html>
項目目錄結構如下，本人使用的是STS：
在STS中啟動項目，訪問localhost:8080/index,效果如下：
