大家好，我是雄雄，欢迎关注微信公众号【雄雄的小课堂】。

前言

大家在写springboot的时候不知道你们遇没遇到过这样的问题，当我们满怀信心的在浏览器中输入：localhost://8080/default，然后回车的时候，期待的页面没有显示出来，而是浏览器将你期待的页面作为一个文件在本地下载下来了？？？今天，我们就来看看出现此问题之后怎么解决。

# 01 #

发现Bug

如前言所述，我将springboot与sringmvc以及mybatis结合的时候，出现的问题，控制器编写正常，返回的是index.jsp，在application.properties中也对页面默认的前缀后缀配置，不可能出现问题，然而运行的时候并未正常显示页面，而是将页面以文件的形式下载下来。

如图所示：

解决Bug

出现该问题的原因我们很容易就能联想到是jsp页面解析的问题，浏览器未编译和解析jsp，导致以文件的形式加载，所以当我们访问的时候，就会变成下载。

解决该问题我们只需要在pom文件中加以下代码即可：

<dependency>
                <groupId>org.apache.tomcat.embed</groupId>
                <artifactId>tomcat-embed-jasper</artifactId>
            </dependency>
            <dependency>
                <groupId>org.apache.tomcat</groupId>
                <artifactId>tomcat-jsp-api</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
                <scope>provided</scope>
            </dependency>

该依赖就是编译解析jsp页面的。
