|
||||
|
||||
## 一、说明
|
||||
|
||||
#### 1.1 项目结构
|
||||
|
||||
<div align="center"> <img src="https://github.com/heibaiying/spring-samples-for-all/blob/master/pictures/spring-boot-jsp.png"/> </div>
|
||||
|
||||
#### 1.2 项目主要依赖
|
||||
|
||||
```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>
|
||||
<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>
|
||||
<groupId>javax.servlet</groupId>
|
||||
<artifactId>jstl</artifactId>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
#### 2.2 在application.yml 中指定访问视图文件的前缀和后缀
|
||||
|
||||
```yml
|
||||
spring:
|
||||
mvc:
|
||||
view:
|
||||
prefix: /WEB-INF/jsp/
|
||||
suffix: .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>
|
||||
```

|
||||
|
||||
## 二、整合 JSP
|
||||
|
||||
### 2.1 基本依赖
|
||||
|
||||
导入整合所需的依赖：
|
||||
|
||||
```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>
|
||||
<groupId>javax.servlet</groupId>
|
||||
<artifactId>jstl</artifactId>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
### 2.2 配置视图
|
||||
|
||||
在 application.yml 中指定访问视图文件的前缀和后缀 ：
|
||||
|
||||
```yml
|
||||
spring:
|
||||
mvc:
|
||||
view:
|
||||
prefix: /WEB-INF/jsp/
|
||||
suffix: .jsp
|
||||
```
|
||||
|
||||
### 2.3 整合测试
|
||||
|
||||
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>
|
||||
```
