Spring Boot 其默认是集成web容器的，启动方式由像普通Java程序一样，main函数入口启动。其内置Tomcat容器或Jetty容器，具体由配置来决定（默认Tomcat）。当然你也可以将项目打包成war包，放到独立的web容器中（Tomcat、weblogic等等），当然在此之前你要对程序入口做简单调整。

项目构建我们使用Maven或Gradle，这将使项目依赖、jar包管理、以及打包部署变的非常方便。

### 一、内嵌 Server 配置 ###

Spring Boot将容器内置后，它通过配置文件的方式类修改相关server配置。  
先看一下下面的图，为关于server的配置列项：  
![配置][20160126173131054]  
![配置][20160126173159436]

其中常用的配置只有少数几个，已经用紫色标记起来。红框圈起来的部分，看名称分类就可以明白其作用。  
对server的几个常用的配置做个简单说明：

# 项目contextPath，一般在正式发布版本中，我们不配置
    server.context-path=/myspringboot
    # 错误页，指定发生错误时，跳转的URL。请查看BasicErrorController源码便知
    server.error.path=/error
    # 服务端口
    server.port=9090
    # session最大超时时间(分钟)，默认为30
    server.session-timeout=60
    # 该服务绑定IP地址，启动服务器时如本机不是该IP地址则抛出异常启动失败，只有特殊需求的情况下才配置
    # server.address=192.168.16.11

Tomcat 
    Tomcat为Spring Boot的默认容器，下面是几个常用配置：

1.  1.  \# tomcat最大线程数，默认为200 
    2.  server.tomcat.max-threads=800 
    3.  \# tomcat的URI编码
    4.  **server.tomcat.uri-encoding=UTF-8** 
    5.  \# **存放Tomcat的日志、Dump等文件的临时文件夹，默认为系统的tmp文件夹**（如：C:\\Users\\Shanhy\\AppData\\Local\\Temp）
    6.  **server.tomcat.basedir**=H:/springboot-tomcat-tmp
    7.  \# 打开Tomcat的Access日志，并可以设置日志格式的方法：
    8.  \#server.tomcat.access-log-enabled=true 
    9.  \#server.tomcat.access-log-pattern=
    10. \# accesslog目录，默认在basedir/logs
    11. \#server.tomcat.accesslog.directory=
    12. \# 日志文件目录
    13. logging.path=H:/springboot-tomcat-tmp
    14. \# 日志文件名称，默认为spring.log
    15. logging.file=myapp.log
