springboot同时支持jsp和html

默认情况下,springboot是不支持jsp的访问的。那么本项目提供以下支持:

  • SpringBoot同时访问html和jsp
  • SpringBoot以jar包运行
  • SpringBoot支持thymeleaf

页面跳转逻辑层

package org.dreams.forepart.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class IndexController {

    @RequestMapping("/jsp")
    public String jsp(Model model) {
        model.addAttribute("message", "this is index jsp page!");
        return "index";
    }

    @GetMapping("/html")
    public String testThemleaf(Model model) {
        model.addAttribute("message", "this is index html page!");
        return "html/index";
    }
}

jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<img src="/img/orcHome.png"/>
${message}
</body>
</html>

html页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<span th:text="${message}"></span>
</body>
</html>

运行入口

package org.dreams.forepart;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
