compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"connectionTimeout="20000"URIEncoding="utf-8"acceptCount="1000"redirectPort="8443"disableUploadTimeout="true"/>参数说明:
Protocol  采用的协议//可将HTTP/1.1改为org.apache.coyote.http11.Http11NioProtocol 启动NIO模式
maxHttpHeaderSize 代表请求和响应的HTTP首部的最大长度，单位是字节。如果不指定，该属性将被设为4096(4K)。
maxThreads 客户请求最大线程数 minSpareThreads Tomcat初始化时创建的 socket 线程数 maxSpareThreads Tomcat连接器的最大空闲 socket 线程数 enableLookups 若设为true, 则支持域名解析，可把 ip 地址解析为主机名 redirectPort 在需要基于安全通道的场合，把客户请求转发到基于SSL 的 redirectPort 端口 acceptAccount 监听端口队列最大数，满了之后客户请求会被拒绝（不能小于maxSpareThreads ） connectionTimeout 连接超时 minProcessors 服务器创建时的最小处理线程数 maxProcessors 服务器同时最大处理线程数 URIEncoding URL统一编码
compression 打开压缩功能 compressionMinSize 启用压缩的输出内容大小，这里面默认为2KB compressableMimeType 压缩类型 connectionTimeout 定义建立客户连接超时的时间. 如果为 -1, 表示不限制建立客户连接的时间
