spring boot 框架构建jsp web应用

说明

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
