SpringBoot集成JSP
加依赖
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<!-- 添加Servlet依赖模块 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
<!-- 添加JSTL标签库依赖模块 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!--添加Tomcat依赖模块.-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<!-- 使用JSP引擎，SpringBoot内置Tomcat没有此依赖 -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
</dependencies>
加配置
#Spring boot视图配置
spring:
mvc:
view:
prefix: /WEB-INF/pages/
suffix: .jsp
加web.xml
src/main/webapp/WEB-INF/web.xml
<web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
</web-app>
加controller
@Controller
public class DemoController {
@RequestMapping("/index")
public String index(HttpServletRequest request)
{
//将用户信息保存到Request对象中
request.setAttribute("name","张三");
//返回首页
return "index";
}
}
加jsp页面
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<title>首页</title>
</head>
<body>
<h3>使用JSP表达式：</h3>
用户姓名：<%= request.getAttribute("name") %><br/>
<h3>使用EL表达式语言：</h3>
用户姓名：${requestScope.name}<br/>
<h3>使用JSTL标签库：</h3>
用户姓名：<c:out value="${requestScope.name}" /><br/>
</body>
</html>
注意这里面的：isELIgnored="false", 否则el表达式不识别。
SpringBoot打war包
启动类继承SpringBootServletInitializer
@SpringBootApplication
public class JspApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(JspApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(JspApplication.class);
}
}
pom设置打包方式为war
<groupId>com.github.xjs</groupId>
<artifactId>springboot-jsp-demo</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
