resin jsp auto-compile

因为resin的自动编译及热部署的特性颇受大家的欢喜，这里总结一下resin2.x下关于自动编译的问题


Resin中 “resin.conf” 自动编译的设置：

1.class-update-interval
  检测servlet更新的时间间隔，默认值2秒
  使用：在  <http-server>标签下：
  <class-update-interval>2s</class-update-interval>
 
2.config-update-interval
  检测配置文件configuration更新的时间间隔，默认值为class-update-interval指定的值 
  使用：在  <http-server>标签下：
  <config-update-interval>2s</config-update-interval> 
 
3.jsp-update-interval
  检测jsp文件的更新时间：默认值为class-update-interval指定的值 
  使用：
  <jsp jsp-update-interval='300s' precompile='true' static-encoding='true' recompile-on-error='true'/>
  其中： precompile 预编译
         static-encoding  允许静态字符编码，默认为true

一般来讲生产环境还是要加大resin对class文件的变化检测的时间间隔，或者干脆不允许扫描。
如果以上方法都无效的话，只能使出俺的必杀技--在jsp标签中添加这句话 auto-compile='false' ，意为不允许编译！

具体请见resin的官网相关介绍！

auto-compile

<jsp auto-compile='false' jsp-update-interval='300s' precompile='true' static-encoding='true' recompile-on-error='true'/>

class-update-interval
    Resin 1.1
Interval in seconds between checking for servlet updates. For development, this can be set to 0 or to a small number to pick up new servlet versions quickly. For deployment, class-update-interval can be large to avoid the overhead of checking for updates.
The default value is 2 seconds.

config-update-interval
    Resin 2.0

Interval in seconds between checking for configuration updates. For development, this can be set to 0 or to a small number to pick up new configuration file versions quickly. For deployment, config-update-interval can be large to avoid the overhead of checking for updates.

The default value is the value of class-update-interval.
