备忘：在web.xml中使用org.springframework.js.resource.ResourceServlet的配置对静态资源的访问

查询了org.springframework.js.resource.ResourceServlet的源程序，发现需要使用这个servlet类时应该可以对以下这些参数进行设置：

gzipEnabled

allowedResourcePaths

compressedMimeTypes

jarPathPrefix

cacheTimeout

我们项目中的使用：

1）将静态内容放入一个单独的project的META-INF目录下，此project将生成jar供其它project调用

2）在web项目的web.xml加入以下配置：

<servlet>

<servlet-name>Resource Servlet</servlet-name>

<servlet-class>org.springframework.js.resource.ResourceServlet</servlet-class>

<init-param>

<param-name>allowedResourcePaths</param-name>

<param-value>

/**/*.css,

/**/*.gif,

/**/*.ico,

/**/*.jpeg,

/**/*.jpg,

/**/*.js,

/**/*.png,

/**/*.html,

META-INF/**/*.css,

META-INF/**/*.gif,

META-INF/**/*.ico,

META-INF/**/*.jpeg,

META-INF/**/*.jpg,

META-INF/**/*.js,

META-INF/**/*.png,

META-INF/**/*.html

</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>Resource Servlet</servlet-name>

<url-pattern>/resources/*</url-pattern>

</servlet-mapping>

3）这样在访问静态页面
META-INF/html/xx.html

时可以通过http://<host>/<context path>/resource/html/xx.html来访问此页面了

4）当想简化以上URL，把resource/html/改为html/时，我加了以下配置，主要是加了
jarPathPrefix

的参数：

<servlet>

<servlet-name>HTML Resource Servlet</servlet-name>

<servlet-class>org.springframework.js.resource.ResourceServlet</servlet-class>

<init-param>

<param-name>allowedResourcePaths</param-name>

<param-value>

/**/*.html,

META-INF/**/*.html

</param-value>

</init-param>

<init-param>

<param-name>jarPathPrefix </param-name>

<param-value>META-INF/html</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>HTML Resource Servlet</servlet-name>

<url-pattern>/html/*</url-pattern>

</servlet-mapping>
