Answer my own question:
Since I'm sure that the pygments components is installed corrected --
for I can see it in the Admin page's plugin section.
And as I note, every Java source code file has a message on top of the
source view page.

* Property svn:mime-type set to text/plain
---------------------------------------------------------------------------------------------------------------------------
I try to update configuration in trac.ini file:
-------------------------------------------------------------------------------------------------------------------------
pygments_modes = text/x-java:java:7, text/x-chdr:h:7, text/x-csrc:c:7,
text/x-c++hdrh:h:7, text/x-c++src:cpp:7, text/x-csharp:cs:7, text/x-
python:py:7
---------------------------------------------------------------------------------------------------------------------------
change "text/x-java:java:7" to "text/plain:java:7", this told pygments
to render text/plain file using java render.
And I got the syntax highlight in the source view page.
I use Eclipse as my IDE and Subversion to add source code to the svn
server. It seems that Subversion plugin of Eclipse had set the
snv:mime-type ?? Or do anyone know how to set the svn:mime-type
property as I need?
