spring-boot整合jsp

spring-boot 支持多种模版引擎：

1.  FreeMarker 
2.  Groovy 
3.  Thymeleaf （Spring 官网使用这个） 
4.  Velocity 
5.  JSP （Spring Boot官方不推荐）

接下来我们教大家如何在spring-boot中使用jsp。

1、pom.xml加入支持jsp的依赖：

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

将 <packaging>jar</packaging> 改成  <packaging>war</packaging>

改完之后别忘了 maven update。

2、application.properties配置文件加入JSP支持：

# 页面默认前缀目录
    spring.mvc.view.prefix=/WEB-INF/page/
    # 响应页面默认后缀
    spring.mvc.view.suffix=.jsp
    # 自定义属性，可以在Controller中读取
    application.hello=Hello World!

3、创建webapp文件夹以及页面：

4、编写jsp页面：

<%@ 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">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>sprint-boot jsp</title>
    </head>
    <body>
        当前系统时间：<br />
        <font size=3 color=red>Time：${time }</font>
    
        <br />
        Message：${message }
    </body>
    </html>

5、编写controller代码：

package nc.edu.nuc.Test.controller;
    
    import java.util.Date;
    
    import javax.servlet.http.HttpServletRequest;
    
    import nc.edu.nuc.Test.entity.Test;
    import nc.edu.nuc.Test.service.TestService;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class TestController {
    	private static final Logger logger = LoggerFactory.getLogger(TestController.class); 
    	
    	@Autowired
    	private TestService testService;
    	
    	@RequestMapping("/test")
        @ResponseBody
        public String test(HttpServletRequest request) {
    		String name = request.getParameter("name");
    		Test findByName = testService.findByName(name);
    		logger.info("test....{}",name);
            return findByName.toString();
        }
    	
    	@RequestMapping("/testJsp")
        public String testJsp(HttpServletRequest request,Model model) {
    		String name = request.getParameter("name");
    		Test findByName = testService.findByName(name);
    		logger.info("testJsp....{}",findByName.toString());
    		
    		model.addAttribute("time", new Date());
    		model.addAttribute("message", findByName.getName());
    		
            return "index";
        }
    
    }

这里用法和springmvc的一样，支持modelView和model...
