spring-boot项目打jar包访问jsp 时报404错误

最近在做项目的迁移重构工作，将原来的ssh 框架的web 项目改造成spring boot 的项目，放到云上docker容器中运行，在改造的过程中一路坎坷，遇到了各种坑，各种奇怪的问题，首先我们来说一下本地启动没问题，服务器启动访问jsp 报404 的问题。
我的pom.xml 文件如下：

数据库配置这里就不贴出来了，本地利用eclipse运行正常，没有任何报错，正常也访问，然后打成jar 包丢到服务器上运行 java -jar cc.jar  
结果报错：

这个就比较郁闷了，本地没有任何报错，丢服务器上就出现问题，应该是缺少jar 包的原因，百度了一下，竟然没有任何有价值的信息，然后再一篇国外的网址张看到这样一篇信息
![在这里插入图片描述](https://img-blog.csdnimg.cn/20190719135545396.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTQ1MjAwMDY=,size_16,color_FFFFFF,t_70)

在pom中引入如下两个jar包，后程序正常启动，访问也正常

jsf-impl jsf-impl 0.9.0 system ${basedir}/src/main/webapp/WEB-INF/lib/jsf-impl.jar

	
		jsf-api
		jsf-api
		0.9.0
		system
		${basedir}/src/main/webapp/WEB-INF/lib/jsf-api.jar
		
	

 总结一下，有几点需要注意一下：
 1. spring-boot-maven-plugin 打包插件版本非常重要，不能高于1.4.2.RELEASE版本
 2. 打jar包后的jsp文件路径是否正确 
 

        
			src/main/webapp
			META-INF/resources
			
				**/**
			
		

 3. 配置文件中的jsp 配置

spring:
mvc:
view:
prefix: /
suffix: .jsp
