大綱

（1）建立Maven web project；

（2）在pom.xml檔案添加依賴

（3）配置application.properties支援jsp

（4）編寫測試Controller

（5）編寫JSP頁面

（6）編寫啟動類App.java

建立Maven web project

使用Eclipse建立一個Maven Web Project ，項目取名為： spring-boot-jsp

在pom.xml檔案添加依賴

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.1.RELEASE</version>
</parent>

<java.version>1.8</java.version>

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

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>

JSTL（JSP Standard Tag Library，JSP標準標籤庫)是一個不斷完善的開放原始碼的JSP標籤庫，是由apache的jakarta小組來維護的。
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>

<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>

application.properties配置

添加src/main/resources/application.properties：

# 頁面預設首碼目錄
spring.mvc.view.prefix=/WEB-INF/jsp/
# 響應頁面預設尾碼
spring.mvc.view.suffix=.jsp
# 自訂屬性，可以在Controller中讀取
application.hello=Hello Angel From application

編寫測試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";
}
}

編寫JSP頁面

在 src/main 下面建立 webapp/WEB-INF/jsp 目錄用來存放我們的jsp頁面：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>

編寫啟動類

@SpringBootApplication
public class App {

public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}

代碼如下：

pom.xml

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.kfit</groupId>  <artifactId>spring-boot-jsp</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>spring-boot-jsp Maven Webapp</name>  <url>http://maven.apache.org</url>    <!-- spring boot parent節點，引入這個之後，在下面和spring boot相關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 ，這裡我們使用jdk 1.8 ,預設是1.6 -->    <java.version>1.8</java.version>  </properties>      <dependencies>        <!-- web支援: 1、web mvc; 2、restful; 3、jackjson支援; 4、aop ........ -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>                <!-- servlet 依賴. -->        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>javax.servlet-api</artifactId>            <scope>provided</scope>        </dependency>                <!--                 JSTL（JSP Standard Tag Library，JSP標準標籤庫)是一個不斷完善的開放原始碼的JSP標籤庫，是由apache的jakarta小組來維護的。         -->        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>jstl</artifactId>        </dependency>                        <!-- tomcat 的支援.-->        <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></project>

Controller類

package com.kfit;import java.util.Map;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class HelloController {        @RequestMapping("/index")    public String index(Map<String,Object> map){        map.put("name", "Andy");        return "index";    }}

配置類

spring.mvc.view.prefix=/WEB-INF/jsp/ spring.mvc.view.suffix=.jsp

啟動類

package com.kfit;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class App {    public static void main(String[] args) {        SpringApplication.run(App.class, args);    }}
