1.maxThreads：设定处理客户请求的线程的最大数目，这个值也决定了服务器可以同时响应客户请求的最大数目，默认值为200.
2.minSpareThreads：设置Tomcat初始化时创建的socket 线程数，默认值为4.
3.maxSpareThreads:设置Tomcat连接器最大空闲socket 线程数，默认值为150.
4.enableLookup：如果设为true,表示支持域名解析，可以把IP地址解析为主机名。Web应用调用request、getRemostltost方法将返回客户的主机名，默认属性是为true。
5.redirectPort：指定转发端口。
6.acceptCount：设定在监听端口队列中的最大客户请求数，默认值为100，如果队列已满客户请求将被拒绝。
7.connectionTimeout：定义建立客户连接超时的时间，默认这为20000毫秒。如果为-1，表示不限制建立客户连接的时间。
8.minProcessors：服务器启动时创建的最小处理线程数，即使没有任何HTTP请求，Tomcat也要保持至少这么多线程以等待处理。
9.maxProcessors：同时最大的处理线程数，如果系统中已经有这个数字的线程，那么更多的连接请求将进入排队。
10.useBodyEncodingForURI：表示是否用request.setCharacterEncoding参数对URL提交的数据和表单中GET方式提交的数据进行重新编码，默认值是false.
