1.要返回jsp頁面需要以下配置：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>2.在application.yml裏配置如下信息：
#路徑名稱按自己需要命名,在WEB-INF下新建文件夾page
spring:
mvc:
view:
prefix: /WEB-INF/page/
suffix: .jsp3.在Controller裏沒什麼變化
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/index")
public class IndexController {
@RequestMapping("/page")
public String indexPage(ModelMap model) {
model.addAttribute("hello", "13212");
return "hello";
}
}4.jsp內容：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
