- 一，序
- 二，样例代码
- 1，代码结构
- 2，完整代码备份
- 三，准备工作
- 1. pom.xml 引入组件
- 2. application.yml 指定jsp配置
- 四，war方式运行
- 1. 修改pom.xml文件
- 2. mvn执行打包
- 五，jar方式运行
- 1. 修改pom-jsp-jar.xml文件
- 2. 修改 spring-boot-maven-plugin添加版本号
- 3. 添加资源文件配置（`Jar运行必须`）
- 4. mvn执行打包
- 六，war、jar方式运行配置文件区别
一，序
Spring Boot 官方不推荐使用JSP来作为视图，但是仍有部分项目使用了JSP视图，Springboot JSP项目运行方式有war、Jar两种方式。
二，样例代码
1，代码结构
2，完整代码备份
如何使用下面的备份文件恢复成原始的项目代码，请移步查阅：神奇代码恢复工具

</body>
</html>三，准备工作
1. pom.xml 引入组件
<!-- JSTL 支持，按需引入 --><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId></dependency><!-- JSP 编译支持，必须引入--><dependency><groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-jasper</artifactId><scope>provided</scope></dependency>
2. application.yml 指定jsp配置
application.yml
spring:mvc:view:prefix: /WEB-INF/viewssuffix: .jsp
四，war方式运行
1. 修改pom.xml文件
<packaging>war</packaging>
2. mvn执行打包
mvn clean package
执行后会在target目录生成war包，拷贝出来后运行
java -jar docker-demo-0.0.1.war
浏览器访问： http://127.0.0.1:8080/user/ 界面如下：
五，jar方式运行
复制 pom.xml重命名为 pom-jsp-jar.xml
1. 修改pom-jsp-jar.xml文件
<packaging>jar</packaging>
2. 修改 spring-boot-maven-plugin添加版本号
注意只能使用1.4.2.RELEASE，其他版本不行
<plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>1.4.2.RELEASE</version></plugin>
3. 添加资源文件配置（Jar运行必须）
<resources><resource><directory>src/main/java</directory><excludes><exclude>**/*.java</exclude></excludes></resource><resource><directory>src/main/resources</directory><includes><include>**/**</include></includes></resource><resource><directory>src/main/webapp</directory><includes><include>**/**</include></includes><targetPath>META-INF/resources</targetPath></resource></resources>
4. mvn执行打包
mvn clean package -f pom-jsp-jar.xml
执行后会在target目录生成 jar包，拷贝出来后运行
java -jar docker-demo-0.0.1.jar
六，war、jar方式运行配置文件区别
有任何问题和建议，都可以向我提问讨论,大家一起进步，谢谢!
