SpringBoot（二）spring-boot-web-jsp
柳杰
springboot中使用jsp作为展示层的示例，其实这个东西 只要你自己愿意看文档 很好学的 ，大家都是边学边研究，
不会了看下官方的文档
官方文档地址：
http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#using-boot-running-your-application
官方还提供了直接生成项目的地址：https://start.spring.io/
本次使用的是自己通过myeclipse创建的maven项目，通过官方的文档将项目跑起来
具体如下maven的配置文件pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

上述配置 如果不想使用 war的形式运行 可以改为jar的形式
启动类SampleWebJspApplication.java SampleWebJspApplication.java
package com.julongtech.action;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
/**
* 主程序启动类 SpringBootServletInitializer web程序需要继承
* @author julong
* @date 2017-8-22 上午11:51:18
*/
@SpringBootApplication
public class SampleWebJspApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SampleWebJspApplication.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(SampleWebJspApplication.class, args);
}
}
package com.julongtech.action;
import java.util.Date;
import java.util.Map;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* 页面跳转类
* @author julong
* @date 2017-8-22 上午11:52:23
*/
@Controller
public class WelcomeController {
@Value("${application.message:Hello World}")
private String message = "Hello World";
@GetMapping("/")
public String welcome(Map<String, Object> model) {
model.put("time", new Date());
model.put("message", this.message);
return "welcome";
}
@RequestMapping("/foo")
public String foo(Map<String, Object> model) {
throw new RuntimeException("Foo");
}
@RequestMapping("/foot")
public String foot(Map<String, Object> model) {
System.out.println("123");
model.put("time", new Date());
model.put("message", this.message);
return "welcome";
}
}
你还需要在 src/main/resource/application.properties创建 application.properties文件 如果你使用的是 spring官方提供的工具生成的项目可以忽略此，只需要在文件中添加配置即可 ：有人说 使用“：” 有人说使用“=” 其实两个都可以 我试过了 ，官方的示例是 ： 文档中是 =
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
application.message: Hello julong
jsp页面 welcome.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html lang="en">
<body>
<c:url value="/resources/text.txt" var="url"/>
<spring:url value="/resources/text.txt" htmlEscape="true" var="springUrl" />
Spring URL: ${springUrl} at ${time}
<br>
JSTL URL: ${url}
<br>
Message: ${message}
</body>
</html>
书写完毕后 点击项目 运行 ，本文使用的jdk1.7
启动后如下：
