[原創]Spring boot 框架構建jsp web應用

說明

Spring boot支持將web項目打包成一個可執行的jar包，內嵌tomcat服務器，獨立部署

為支持jsp，則必須將項目打包為war包

pom.xml中設置打包方式

<packaging>war</packaging>

依賴包導入

Srping boot web項目原本會包含依賴項（starter-web模塊內部依賴包含了spring-boot-starter-tomcat模塊）

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

增加如下依賴

<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作為集成開發環境，則scope需要設置為compile <scope>compile</scope>

參考

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文件目錄

在main目錄下與resources同級別，建立目錄webapp/WEB-INF/jsp/，所有jsp文件將放置與此目錄中
配置ViewResolver，指定jsp目錄

	/**
	 * 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;
	    }
	}

資源目錄

資源目錄直接位於webapp目錄下，如圖片目錄為 webapp/imgs/

假設目錄結構如下，welcome.jsp中以 <img src="imgs/spring.jpg" /> 引用圖片資源

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

啟動服務

通過 mvn package 完成編譯打包，target目錄中將生成可執行的xx.war文件

通過 java -jar xx.war 啟動服務
