# Spring Boot 2.X整合JSP #

> 虽然Spring Boot官方不推荐使用JSP技术，但是对于一些小公司或者ZF网站，还是有必要的。本文将简单介绍Spring Boot 2.X如何整合JSP实现快速开发。

## 新建项目 ##

这里可以用 **Spring Initializr** 快速创建一个`Spring Boot`项目，修改打包方式位`war`：  
![packaging][]  
或者修改`pom.xml`中的`packaging`属性为`war`:

## 添加依赖 ##

`pom.xml`：

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

## 新建目录 ##

新建`src/main/webapp/WEB-INF/views`目录用于存放`jsp`资源文件：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0UwOTYyMDEyNg_size_16_color_FFFFFF_t_70]

## 修改配置 ##

修改`application.yml` / `application.properties`文件：

spring:
      mvc:
        view:
          prefix: /WEB-INF/views/
          suffix: .jsp

## 编写代码 ##

*  创建`index.jsp`:

<%--
      Created by IntelliJ IDEA.
      User: xudc
      Date: 2018/12/11
      Time: 21:24
      To change this template use File | Settings | File Templates.
    --%>
    <%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>Title</title>
    </head>
    <body>
    <h3>Welcome,${name}!</h3>
    
    This is a jsp page.<br/>
    
    </body>
    </html>

*  新建`controller`

/** * @author xudc * @date 2018/12/11 21:19 */
    @Controller
    public class IndexController { 
    
        @GetMapping("/")
        public String index(Model model){ 
            model.addAttribute("name","xudc");
            return "index";
        }
    }

## 启动运行 ##

*  配置外部Tomcat、Jetty等Web容器运行：  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0UwOTYyMDEyNg_size_16_color_FFFFFF_t_70 1]
 *  以Maven Plugins的spring-boot:run运行;  
    切换到对应目录，直接在命令行输入以下命令启动：

mvn spring-boot:run

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0UwOTYyMDEyNg_size_16_color_FFFFFF_t_70 2]

## 访问测试 ##

浏览器打开[http://localhost:8080/][http_localhost_8080]：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0UwOTYyMDEyNg_size_16_color_FFFFFF_t_70 3]  
OK.至此，`Spring Boot 2`就简单的实现对`JSP`的支持了。

> 这里还是推荐大家用Spring Boot 官方推荐的模板引擎，比如：thymeleaf、freemarker等.
