3-springboot项目使用jsp

1、在pom.xml文件中配置依赖项

<!--前端页面使用JSP-->
<!--引入Spring Boot内嵌的Tomcat对JSP的解析包-->
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<!--jstl标签依赖的jar包start -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
</dependency>
<!--jstl标签依赖的jar包end -->

2、在application.properties文件配置spring mvc的视图展示为jsp：

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

3、在src/main 下创建一个webapp目录，然后在该目录下新建jsp页面

4、Maven的pom.xml中配置页面编译位置

<build>
    <resources>

<resource>
    <directory>src/main/webapp</directory>
    <targetPath>META-INF/resources</targetPath>
    <includes>
        <include>**/*.*</include>
    </includes>
</resource>

 </resource>
</resources>
