springMVC+velocity配置

闲话不多说，以下是本人整合springMVC+velocity的一些心得和体会

tool.xml和velocity.properties 两个文件，在jar包中都可以找到的

velocity.jar velocity.properties -->> org.apache.velocity.runtime.defaults.velocity.properties

velocity-tool.jar tools.xml -->> org\apache\velocity\tools\generic\tools.xml 记得改下标签。

velocity.properties要改一下

velocimacro.library = /macros.vm

velocimacro.library = /macros.vm

input.encoding=UTF-8 output.encoding=UTF-8

input.encoding=UTF-8
output.encoding=UTF-8

macros.vm这个随你自己想不想要，反正默认也是会加载好多spring的宏的。编码是一定要设置的。

这些设置完了，还有一点非常重要，这点纠结了我很久 。

就是你明明已经都配置好了，自己都觉得没问题了，action都进了，最后跳到模板引擎去加载模板的时候，告诉你这个模板找不到！！

经过我仔细排查，是velocity.properties多了句配置，自己需要注释一下。

view plaincopyprint?





#file.resource.loader.path = .

#file.resource.loader.path = .

将这句配置注释，这是说，路径为properties文件路径，但如果你的properties跟你的templates不在一个目录，这时候就会出问题了。我调进去看过，它默认就是templates目录，上面宏的地址，也是相对于templates的目录。
