方法详细资料

• setRedirectPatterns

  public void setRedirectPatterns​(String... redirectPatterns)

  Configure one more simple patterns (as described in PatternMatchUtils.simpleMatch(java.lang.String, java.lang.String)) to use in order to recognize custom redirect prefixes in addition to "redirect:".

  Note that simply configuring this property will not make a custom redirect prefix work. There must be a custom View that recognizes the prefix as well.

  从以下版本开始:

  The configured redirect patterns, if any.

  public boolean supportsReturnType​(MethodParameter returnType)

  参数:

  returnType - the method return type to check

  webRequest - the current request

  抛出:

  Exception - if the return value handling results in an error
