Spring boot 框架构建jsp web应用

Spring boot支持将web项目打包成一个可执行的jar包，内嵌tomcat服务器，独立部署

为支持jsp，则必须将项目打包为war包

pom.xml中设置打包方式

<packaging>war</packaging>

依赖包导入

Srping boot web项目原本会包含依赖项（starter-web模块内部依赖包含了spring-boot-starter-tomcat模块）

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

增加如下依赖

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

注意：若使用intellij作为集成开发环境，则scope需要设置为compile <scope>compile</scope>

参考

I can confirm that the IntelliJ error happens for me when I try to run a @SpringBootApplication class directly (without using maven/gradle). It happens in both versions on IntelliJ.

It is fixed temporarily if you follow the instructions @xilin, but these changes are overridden anytime the Gradle project is reimported (and it's annoying to have to tell new devs to do this).

建立jsp文件目录

在main目录下与resources同级别，建立目录webapp/WEB-INF/jsp/，所有jsp文件将放置与此目录中
配置ViewResolver，指定jsp目录

	/**
	 * Created by Ant on 2015/4/11.
	 * QQ:517377100
	 */
	@Configuration
	public class JspConfiguration {
	    @Bean
	    InternalResourceViewResolver internalResourceViewResolver () {
	        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
	        viewResolver.setPrefix("/WEB-INF/jsp/");
	        viewResolver.setSuffix(".jsp");
	        return viewResolver;
	    }
	}

资源目录

资源目录直接位于webapp目录下，如图片目录为 webapp/imgs/

假设目录结构如下，welcome.jsp中以 <img src="imgs/spring.jpg" /> 引用图片资源

webapp/
	imgs/
		spring.jpg
	WEB-INF/
		jsp/
			welcome.jsp
	

启动服务

通过 mvn package 完成编译打包，target目录中将生成可执行的xx.war文件

通过 java -jar xx.war 启动服务
