idea springboot集成jsp

第一步

首先 先在pom.xml加入

<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
		<dependency>
		   <groupId>org.springframework.boot</groupId>
		   <artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>jstl</artifactId>
			<version>1.2</version>
		</dependency>
		<dependency>
			<groupId>org.apache.tomcat.embed</groupId>
			<artifactId>tomcat-embed-jasper</artifactId>
		</dependency>

并且改成war包

<packaging>war</packaging>

第二步

在入口类里继承

SpringBootServletInitializer

重写这个方法

protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {

这里先贴出我的代码

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
@ServletComponentScan
public class JspdemoApplication  extends SpringBootServletInitializer {

	public static void main(String[] args) {
		SpringApplication.run(JspdemoApplication.class, args);
	}
	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
		// 注意这里要指向原先用main方法执行的Application启动类
		return builder.sources(JspdemoApplication.class);
	}
}

第三步

在application配置文件里

spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

写好配置

第四步

在main添加webapp文件夹

在webapp文件夹下添加WEB-INF文件夹并且添加一个index.jsp

点击左上角菜单File->Project Structure->Modules 

然后点击下图的绿色加号 添加一个Web

配置如下

随后WEB-INF会自动生成web.xml文件

最后输入localhost:8080/index.jsp即可
