speingboot使用jsp

1.在src/main目录下新建webapp目录

2.在项目结构把新建的webapp作为Web的资源目录

3.添加依赖

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
    <scope>provided</scope>
</dependency>

4.build标签下添加

<!--指定jsp编译后存放的目录-->
        <resources>
            <resource>
                <!--jsp原来的目录-->
                <directory>src/main/webapp</directory>
                <!--指定编译后的存放目录-->
                <targetPath>META-INF/resources</targetPath>
                <!--指定处理的目录和文件-->
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
        </resources>

5.编辑application.properties文件

#设置端口号
#设置项目端口号
server.port=8080
#设置项目上下文根
server.servlet.context-path=/myWeb

#配置视图解析器
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

6.控制类

@Controller
public class MyController {
    @RequestMapping("/hello")
    public String doSome(Model model) {
        model.addAttribute("data", "SpringBoot使用jsp");
        return "hello";
    }
}

7.前端代码

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%
    String base = request.getContextPath() + "/";
    String url = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + base;
%>
<html>
<head>
    <base href="<%=url%>">
    <title>Title</title>
</head>
<body>
    <h3>hello:${data}</h3>
</body>
</html>
