IDE创建Maven项目

MVC展示层模板Spring Boot官方不推荐使用JSP，
但是像我这有已经用惯了JSP，再换FreeMarker/Velocity学习成本有点大。
还用JSP，有两块需要注意的地方。

需要创建Maven web项目，在IDE中创建maven项目时，ArtifactId选maven-archtype-webapp

需要在src/main/resources目录下的核心配置文件application.properties中追加如下配置
application.properties

spring.mvc.view.prefix=/WEB-INF/views/spring.mvc.view.suffix=.jsp

最简单pom依赖

    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.5.6.RELEASE</version>    </parent>    <dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>javax.servlet-api</artifactId>            <scope>provided</scope>        </dependency>        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>jstl</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-tomcat</artifactId>            <scope>provided</scope>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-tomcat</artifactId>            <scope>provided</scope>        </dependency>        <dependency>            <groupId>org.apache.tomcat.embed</groupId>            <artifactId>tomcat-embed-jasper</artifactId>            <scope>provided</scope>        </dependency>     </dependencies>

JSP页面开发

新建源文件夹src/main/webapp
在src/main/webapp下创建WEB-INF/views文件夹
tt.jsp内容如下

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><!DOCTYPE html><html lang="zh"><head>    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>    <title>Full Layout - jQuery EasyUI Demo</title></head><body>    <input type="button" value="点我" onclick="f()"/>    <input type="text" style="height:100px;width:90%" id="input"/></body></html>

Java后端代码

driver.TesterMan.java

package driver;import java.util.Map;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@EnableAutoConfiguration@Controllerpublic class TesterMan{    public static void main(String[] args) throws Exception {        SpringApplication.run(TesterMan.class, args);        System.out.println("spring boot running ...");    }      @RequestMapping("/tt")    public String index(Map<String,Object> ){        return "/tt";    }}

测试

以java application运行程序
在浏览器访问localhost:8080/tt
看到一个按钮控件、一个文本框控件,说明Spring Boot + Jsp整合成功
