简单的springboot应用，日志，静态资源配置

1.新建Maven项目

2.pom文件

3.项目的结构

4.SpringbootApplication.java

 1 package com.springboot;
 2 
 3 import org.springframework.boot.SpringApplication;
 4 import org.springframework.boot.autoconfigure.SpringBootApplication;
 5 
 6 /**
 7  * @author luoxianwei
 8  * @date 2018/4/24
 9  */
10 @SpringBootApplication
11 public class SpringbootApplication {
12     public static void main(String[] args) {
13         SpringApplication.run(SpringbootApplication.class,args);
14     }
15 }

5.application.properties

1 server.port=8081
2 server.servlet-path=/
3 spring.resources.static-locations=classpath:/static/,classpath:/templates/
4 spring.mvc.view.suffix=.html
5 #配置日志
6 #配置日志在resource下的logback.xml文件中
7 #在控制台输出彩色日志
8 spring.output.ansi.enabled=always

6.日志文件配置logback.xml

29      * spring boot项目只有src目录，没有webapp目录，会将静态访问(html/图片等)映射到其自动配置的静态目录，如下
30      * /static
31      * /public
32      * /resources
33      * /META-INF/resources
34      *
35      *动态页面
36      * 动态页面需要先请求服务器，访问后台应用程序，然后再转向到页面，比如访问JSP。spring boot建议不要使用JSP，
37      * 默认使用Thymeleaf来做动态页面。
38      *  在pom.xml  中添加Thymeleaf组件
39      * templates目录为spring boot默认配置的动态页面路径。
