大体步骤:
(1)创建Maven web project;
(2)在pom.xml文件添加依赖;
(3)配置application.properties支持jsp
(4)编写测试Controller
(5)编写JSP页面
(6)编写启动类Application.Java
1,FreeMarker
2,Groovy
3,Thymeleaf (spring 官网使用这个)
4,Velocity
5,JSP (貌似Spring Boot官方不推荐,STS创建的项目会在src/main/resources 下有个templates 目录,这里就是让我们放模版文件的,然后并没有生成诸如 SpringMVC 中的webapp目录)
不过本文还是选择大家都熟悉的JSP来举例,因为使用JSP与默认支持的模版需要特殊处理,所以拿来举例更好。
(1)创建Maven web project
使用Eclipse新建一个Maven Web Project ,项目取名为:
spring-boot-jsp
(2)在pom.xml文件添加依赖

(3)application.properties配置
上面说了spring-boot 不推荐JSP,想使用JSP需要配置application.properties。
添加src/main/resources/application.properties内容:

# 页面默认前缀目录 spring.mvc.view.prefix=/WEB-INF/jsp/ # 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 Angel From application |
(4)编写测试Controller

package com.example.jsp.controller; import java.util.Map; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class HelloController { //从application中读取配置,如取不到默认值为hello jack @Value ( "${application.hello:hello jack}" ) private String hello; @RequestMapping ( "/helloJsp" ) public String helloJsp(Map<String, Object> map){ System.out.println( "HelloController.helloJsp().hello=" +hello); map.put( "hello" , hello); return "helloJsp" ; } } |
(5)编写JSP页面
在 src/main 下面创建 webapp/WEB-INF/jsp 目录用来存放我们的jsp页面:helloJsp.jsp

右键Run As Java Application访问:http://127.0.0.1:8080/helloJsp 可以访问到:
helloJsp
Hello Angel From application
