setPathPrefix

public void setPathPrefix(String pathPrefix)

Set the prefix for all paths. This is useful if you want to apply the filter to something other then /*, perhaps because you are merging this filter into a larger web application. For example, if web.xml specifies:

 <filter-mapping>
  <filter-name>SolrRequestFilter</filter-name>
  <url-pattern>/xxx/*</url-pattern>
 </filter-mapping>
 

Make sure to set the PathPrefix to "/xxx" either with this function or in web.xml.

 <init-param>
  <param-name>path-prefix</param-name>
  <param-value>/xxx</param-value>
 </init-param>
 

getPathPrefix

public String getPathPrefix()
