Spring velocity

默认情况下，velocity macro文件修改没有被应用服务器检测，必须重启才能生效。





Spring web.xml contextConfigLocation配置包含属性文件mvc-config.xml



<servlet>

<servlet-name>dispatcherServlet</servlet-name>    

<servlet-class> org.springframework.web.servlet.DispatcherServlet       </servlet-class>     

<init-param>         

<param-name>contextConfigLocation</param-name>        

<param-value>

/WEB-INF/mvc-config.xml

/WEB-INF/alert-config.xml

</param-value>  

</init-param> 

<load-on-startup>1</load-on-startup> 

</servlet>





mvc-config.xml部分内容如下：



             <bean id="velocityConfigurer"                        class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">

             <property name="resourceLoaderPath">

            <value>WEB-INF/velocity/</value> 

             </property>

             <property name="velocityProperties">

                    <props>

                    <prop key="input.encoding">gb2312</prop>

                    <prop key="output.encoding">gb2312</prop>

                    <prop key="contentType">text/html;charset=gb2312</prop>

                    <prop key="file.resource.loader.cache">false</prop>

                    <prop key="file.resource.loader.modificationCheckInterval">1</prop>

                    <prop key="velocimacro.library.autoreload">true</prop>

                   <prop key="velocimacro.library">templates.vm</prop>

                    <prop key="runtime.log.logsystem.class">org.apache.velocity.runtime.log.SimpleLog4JLogSystem</prop>

                    <prop key="runtime.log">com.ali</prop>

                    <prop key="runtime.log.error.stacktrace">true</prop>

                    <prop key="runtime.log.warn.stacktrace">true</prop>

                    <prop key="runtime.log.info.stacktrace">false</prop>

                    <prop key="runtime.log.invalid.reference">true</prop>

            </props>

             </property>



      </bean>

     

       <bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">

         <property name="suffix"><value>.vm</value></property>

                    <property name="exposeSpringMacroHelpers"><value>true</value></property>

                    <property name="exposeRequestAttributes"><value>true</value></property>

                    <property name="exposeSessionAttributes"><value>true</value></property>

                    <property name="contentType" value="text/html;charset=gb2312" />

                    <property name="dateToolAttribute">

     <value>dateTool</value>

         </property>

       </bean>







Velocity文件包括库文件templates.vm都放在WEB-INF/velocity/

确保velocity文件被修改都立即重新扫描，关键的参数：

<prop key="file.resource.loader.cache">false</prop>

                    <prop key="file.resource.loader.modificationCheckInterval">1</prop>

                    <prop key="velocimacro.library.autoreload">true</prop>





在index.vm上通过：

#parse("templates.vm")引入velocity模版。
