框架类---springBoot---tomcat启动并支持跳转JSP文件

1.SpringBoot启动类继承SpringBootServletInitializer(注意如果还想在开发工具run方法启动的时候需要将继承SpringBootServletInitializer的类单独提取出来，不然报错:找不到main)

2.重写configure方法

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}

public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}

}

3.配置pom.xml文件,将打包类型改为war(tomcat支持war部署)

<packaging>war</packaging>

4.配置pom.xml文件,修改导入jar的作用域（此步骤是将tomcat相关包部部署的时候不添加到部署文件中）

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>

5.添加jsp对应的jar

<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>

6.bootstrap.properties配置文件添加

spring.mvc.view.prefix=/WEB-INF/view/
spring.mvc.view.suffix=.jsp

ps:

对于第4点，当使用的是tomcat8的时候直接用tomcat启动没有问题，然而当用tomcat7启动的时候会报错所以要添加第4点。下图是报错的截图
