springboot第一章09---添加jsp支持

操作步骤：

1.创建Maven Web Project

2.在pom.xml中添加依赖

3.配置application.properties支持jsp

4.编写测试controller

5.编写jsp页面

6.编写启动类App.java

第一步：略过

第二步：pom.xml

   <!-- spring-boot父节点依赖，相关的引入就不需要添加version配置，spring boot会选择最合适的版本进行添加  -->
	<parent>

	    <!-- 指定jdk为1.8，默认为1.6 -->
	    <java.version>1.8</java.version>
	  </properties>
	  
  <dependencies>
  
  	<!-- 由于上面spring-boot-starter-parent已经指定了版本号，系统会自动选择合适的版本号，不需要再添加 -->

	<!-- servlet依赖 -->

    </dependency>
  </dependencies>
  <build>
    <finalName>spring-boot-jsp</finalName>
  </build>
</project>

第三步：application.properties

##访问jsp资源的前缀
spring.mvc.view.prefix = /WEB-INF/jsp/
##后缀
spring.mvc.view.suffix = .jsp

第四步：JspTestController.java

第五步：index.jsp 

第六步：编写App.java并启动

第七步：测试
