## 一、说明
#### 1.1 项目结构
![spring-boot-servlet](D:\spring-samples-for-all\pictures\spring-boot-jsp.png)

```xml
<!--整合 jsp 依赖包-->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
<!--jsp jstl 标签支持-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
```
## 二、整合 jsp
#### 2.1 导入整合的依赖
```xml
<!--整合 jsp 依赖包-->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
<!--jsp jstl 标签支持-->
<dependency>

```yml
spring:
mvc:
view:
prefix: /WEB-INF/jsp/

```
#### 2.3 新建controller和show.jsp 测试整合是否成功
```java
@Controller
@RequestMapping("index")
public class JspController {
@RequestMapping
public String jsp(Model model){
Programmer programmer = new Programmer("heibai", 21, 1298.31f, LocalDate.now());
model.addAttribute("programmer",programmer);
return "show";
}
}
```
```jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>programmer</title>
<link rel="stylesheet" href="${pageContext.request.contextPath}/css/show.css">
</head>
<body>
<ul>
<li>姓名: ${programmer.name}</li>
<li>年龄: ${programmer.age}</li>
</ul>
</body>
</html>
