Springboot 不建議使用ＪＳＰ
原因;
- 在tomcat上，jsp不能在嵌套的tomcat容器解析即不能在打包成可執行的jar的情況下解析
- Jetty 嵌套的容器不支持jsp
- Undertow
官方推薦使用模版引擎，thymelef。
下面是JSP總結
1、創建MAVEN工程要用ＪＳＰ必須要用war包
Pom.xml 引入相關依賴
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

<artifactId>spring-boot-starter-tomcat</artifactId>

<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
</dependencies>
//這裏是因爲創建的<packaging>war</packaging> Pom.xml 有紅叉叉，加入下面代碼就可以了。
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
</project>
創建controller層
package thymelef.com.Coutroller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class CoutrollerTest {
@RequestMapping("/index")
public String index(Model model){
model.addAttribute("name", "fujiashi");
return"index";
}
}
創建啓動類
package thymelef.com.Test;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
@Controller
@SpringBootApplication(scanBasePackages={"thymelef.com.Coutroller"})
public class JspTest {
public static void main(String[] args) {
SpringApplication.run(JspTest.class, args);
}
}
創建jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
${name}
</body>
</html>
需要建立application.properties
spring.mvc.view.prefix=/jsp/ 前綴
spring.mvc.view.suffix=.jsp 後綴
最後訪問
http://localhost:8080/index
