添加freemarker的shiro标签

上次写的集成shiro的标签是直接通过maven导入的jar包，但是发现引入了很多无用的jar。现在直接通过代码导入shiro的标签。shiro标签可以在http://download.csdn.net/detail/nightliar/9838637处下载。

1.首先新建一个BaseFreemarkView.java类，继承freemarker的视图类FreeMarkerView。

package com.business.util;
    
    import java.util.Map;
    
    import javax.servlet.http.HttpServletRequest;
    
    import org.springframework.web.servlet.view.freemarker.FreeMarkerView;
    
    import com.business.shiro.freemarker.ShiroTags;
    import com.common.web.util.RequestUtils;
    
    public class BaseFreemarkView extends FreeMarkerView {
    
    	@Override
    	protected void exposeHelpers(Map<String, Object> model,HttpServletRequest request) throws Exception {
            model.put("base", RequestUtils.getDomain(request));
            model.put(Constant.IMAGE_DOMAIN, Configurer.getProperty(Constant.IMAGE_DOMAIN));
            model.put(Constant.FRONT_DOMAIN, Configurer.getProperty(Constant.FRONT_DOMAIN));
            model.put(Constant.DOWNLOAD_DOMAIN, Configurer.getProperty(Constant.DOWNLOAD_DOMAIN));
            model.put("base", RequestUtils.getDomain(request));
            model.put("shiro", new ShiroTags());//shiro标签
    		super.exposeHelpers(model, request);
    	}
    }

2.在spring-mvc-servlet.xml中修改freemarker的配置，将BaseFreemarkView配置进去。

<bean id="freeMarkerConfigurer" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
                    <property name="templateLoaderPath" value="/WEB-INF/template/" />
                    <property name="freemarkerSettings">
                            <props>
                                    <prop key="template_update_delay">0</prop>
                                    <prop key="defaultEncoding">UTF-8</prop>
                                    <prop key="url_escaping_charset">UTF-8</prop>
                                    <prop key="locale">zh_CN</prop>
                                    <prop key="boolean_format">true,false</prop>
                                    <prop key="date_format">yyyy-MM-dd</prop>
                                    <prop key="time_format">HH:mm:ss</prop>
                                    <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>
                                    <prop key="number_format">#.##</prop>
                                    <prop key="whitespace_stripping">true</prop>
                                    <prop key="classic_compatible">true</prop>
                                    <prop key="template_exception_handler">ignore</prop>
                            </props>
                    </property>
            </bean>
    
            
            <bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
                    <property name="viewClass" value="com.business.util.BaseFreemarkView" />
                    <property name="cache" value="true" />
                    <property name="order" value="0" />
                    <property name="prefix" value="" />
                    <property name="suffix" value=".html" />
                    <property name="contentType" value="text/html;charset=UTF-8" />
                    <property name="requestContextAttribute" value="request" />
                    <property name="exposeSpringMacroHelpers" value="true" />
                    <property name="exposeRequestAttributes" value="true" />
                    <property name="exposeSessionAttributes" value="true" />
            </bean>

这个和以前配置的不一样，这里只是在视图里面配置，所以只会再视图里显示，在shiro的那篇文章中是在全局配置的。这里还在BaseFreemarkView里加入了一些通用的全局变量。
