SPRINGMVC Configuration Multi-view Jsp+freemarker, Practice success! (Many pits on the net)

Today, I configured a SPRINGMVC multi-view, this thought is very simple, after practice found a variety of problems, on-line search a lot of information, finally chose to see the source, finally know why failed, the following introduction.

Failed configuration! Success just changed a few small places.

The above is the most of the configuration I found on the Internet, the problem is, with the JSP configuration as an example:

<property name= "Viewnames" value= "*.jsp"/> <property name= "suffix" value= ". jsp"/> <property Name= "Order" value= "1"/>

First: Some people say that the order attribute does not work, I see the source debug when it is useful, he will specify which configuration to create the view, (the smaller the number the higher the priority), for example: Most of your project is a JSP is very rarely a part of the FTL or other views, If there is no special requirement, the JSP priority level should be higher, so that he will directly match the JSP view, and the match will not be looking for the FTL view.

The following goes to the point, is also the problem of the place,

Viewnames: Property represents the name of your return view. The file name must be suffixed so that spring goes back to determine if it ends with a. jsp.

If you do return the file name + suffix name, but suffix: the attribute will add a suffix to your view before creating it. JSP, so spring will help you add it again. JSP, which is sure to end up with an exception to the file that cannot be found.

Part of the source code:

Public static boolean simplematch (STRING PATTERN, STRING STR)  {if  ( pattern == null | |  str == null)  {return false;} Int firstindex = pattern.indexof (' * ');if  (firstindex == -1)  {return  Pattern.equals (str);} if  (firstindex == 0)  {if  (Pattern.length ()  == 1)  {return true;} Int nextindex = pattern.indexof (' * ',  firstindex + 1);if  (nextIndex ==  -1)  {return str.endswith (pattern.substring (1));} String part = pattern.substring (1, nextindex); Int partindex = str.indexof ( part);while  (partindex != -1)  {if  (SimpleMatch (pattern.substring (nextindex),  Str.substring (Partindex + part.length ())))  {return true;} Partindex = str.indexof (part, partindex + 1);} Return false;} return  (Str.length ()  >= firstindex &&pattern.substring (0, firstindex). Equals ( Str.substring (0, firstindex))  &&simplematch (pattern.substring (firstIndex),  Str.substring (FirstIndex)));}

The correct configuration is

<property name= "Viewnames" value= "*.jsp"/> <property name= "suffix" value= "/>

Java:

return "/jsp.jsp";

If you return without a suffix name,

<property name= "viewnames" value= "/> <property name=" suffix "value=". jsp "/>

Java:

return "/jsp";

I do not know so people will understand, these 2 properties can not be set, Spring automatically help you find the view you want, do not have to re-implement the Viewresolver interface, there are special circumstances can implement their own logic,
