processRequest

public RewrittenUrl processRequest(javax.servlet.http.HttpServletRequest hsRequest,
                                   javax.servlet.http.HttpServletResponse hsResponse)
                            throws java.io.IOException,
                                   javax.servlet.ServletException,
                                   java.lang.reflect.InvocationTargetException

Helpful for testing but otherwise, don't use.

参数:

hsRequest - HttpServletRequest

hsResponse - HttpServletResponse

返回:

RewrittenUrl

抛出:

java.io.IOException - IOException

javax.servlet.ServletException - ServletException

java.lang.reflect.InvocationTargetException - InvocationTargetException

processRequest

public boolean processRequest(javax.servlet.http.HttpServletRequest hsRequest,
                              javax.servlet.http.HttpServletResponse hsResponse,
                              javax.servlet.FilterChain parentChain)
                       throws java.io.IOException,
                              javax.servlet.ServletException

The main method called for each request that this filter is mapped for.

参数:

hsRequest - The request to process.

hsResponse - HttpServletResponse

parentChain - FilterChain

返回:

returns true when response has been handled by url rewriter false when it hasn't.

抛出:

java.io.IOException - IOException

javax.servlet.ServletException - ServletException

getPathWithinApplication

public java.lang.String getPathWithinApplication(javax.servlet.http.HttpServletRequest request)

参数:

request - HttpServletRequest

返回:

String

getContextPath

public java.lang.String getContextPath(javax.servlet.http.HttpServletRequest request)

参数:

request - HttpServletRequest

返回:

String

decodeRequestString

public java.lang.String decodeRequestString(javax.servlet.http.HttpServletRequest request,
                                            java.lang.String source)

参数:

request - HttpServletRequest

source - String

返回:

String

handleInvocationTargetException

public RewrittenUrl handleInvocationTargetException(javax.servlet.http.HttpServletRequest hsRequest,
