添加JSP支持

 
 
pom.xml文件添加依赖
<!-- spring boot parent节点,引入这个之后,在下面和spring boot相关的就不需要引入版本了; -->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.1.RELEASE</version>
</parent>
 
 
 
<properties>
<!-- 指定一下jdk的版本 ,这里我们使用jdk 1.8 ,默认是1.6 -->
<java.version>1.8</java.version>
</properties>
 
 
<dependencies>
<!-- web支持: 1、web mvc; 2、restful; 3、jackjson支持; 4、aop ........ -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
 
<!-- servlet 依赖. -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
 
<!--
JSTL(JSP Standard Tag Library,JSP标准标签库)是一个不断完善的开放源代码的JSP标签库,是由apache的jakarta小组来维护的。
-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
 
 
<!-- tomcat 的支持.-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
 
 
</dependencies>
<build>
<finalName>spring-boot-jsp</finalName>
</build>
 
3application.properties配置
添加src/main/resources/application.properties
# 页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/jsp/
# 响应页面默认后缀
spring.mvc.view.suffix=.jsp
# 自定义属性,可以在Controller中读取
application.hello=Hello Angel From application
 
4)编写测试Controller
@Controller
public class HelloController {
private String hello;   
 
  @RequestMapping("/helloJsp")
  public String helloJsp(Map<String,Object> map){
  System.out.println("HelloController.helloJsp().hello=hello");
  map.put("hello", hello);
  return "helloJsp";
  }
}
 
 
5)编写JSP页面
在 src/main 下面创建 webapp/WEB-INF/jsp 目录用来存放我们的jsp页面:helloJsp.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>
•  helloJsp
•  <hr>
•  ${hello}
• 
•</body>
•</html>
 
 
6)编写启动类
@SpringBootApplication
public class App {
 
  public static void main(String[] args) {
  SpringApplication.run(App.class, args);
  }
}
 
 
特别说明:针对el表达式,类似${hello} 这个对于servlet的版本是有限制的,2.4版本版本以下是不支持的,是无法进行识别的,请注意。
