Using shiro tags in freemarker

Inherit the FreeMarkerConfigurer class and override the afterPropertiesSet() method;

import com.jagregory.shiro.freemarker.ShiroTags;
import freemarker.template.TemplateException;
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;

import java.io.IOException;

/**
 * 继承FreeMarkerConfigurer类,重写afterPropertiesSet()方法；
 * 集成shiroTags标签
 * Created by zsc on 2016/1/5.
 */
public class ShiroTagFreeMarkerConfigurer extends FreeMarkerConfigurer {

    @Override
    public void afterPropertiesSet() throws IOException, TemplateException {
        super.afterPropertiesSet();
        this.getConfiguration().setSharedVariable("shiro", new ShiroTags());
    }

}

Need to add jar package     shiro-freemarker-tags-0.1-SNAPSHOT.jar

<bean
		class="com.shiro.shiro.ShiroTagFreeMarkerConfigurer">
		<property name="templateLoaderPath" value="/WEB-INF/page/" />
		<property name="freemarkerSettings">
			<props>
				<prop key="defaultEncoding">UTF-8</prop>
			</props>
		</property>
	</bean>

If you have previously configured

<bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer" Change this class to

ShiroTagFreeMarkerConfigurer

This class will do

Then call directly in the foreground:

    guest tag: verify whether the current user is a "guest", that is, an unauthenticated (including unremembered) user; shiro tag: <shiro:guest></shiro:guest>; in freemark: <@shiro.guest> </ @shiro.guest> 
    user tag: authenticated or remembered user shiro tag: <shiro:user> </shiro:user> ; in freemark: <@shiro.user> </@shiro.user> 
    authenticated tag: An authenticated user. Remembered users are not included, which is the difference from the user tag. shiro tag: <shiro:authenticated> </shiro:authenticated>; in freemark: <@shiro.authenticated></@shiro.authenticated>
    notAuthenticated tag: unauthenticated users. Opposite of authenticated tag. shiro tag: <shiro:notAuthenticated> </shiro:notAuthenticated>; in freemark: <@shiro.notAuthenticated></@shiro.notAuthenticated>
    principal tag: output current user information, usually login account information shiro tag: Hello, < @shiro.principal property="name" /> ; in freemarker: Hello, <@shiro.     
    hasRole tag: Verify whether the current user belongs to this role, shiro tag: <shiro:hasRole name="administrator"> Administer the system </shiro:hasRole> ; in freemarker: <@shiro.hasRole name=”admin”>Hello admin !</@shiro.hasRole> 
    hasAnyRoles tag: Verify that the current user belongs to any of these roles, separated by commas, shiro tags: <shiro:hasAnyRoles name="admin,user,operator"> Administer the system < /shiro:hasAnyRoles> ; in freemarker: <@shiro.hasAnyRoles name="admin,user,operator">Hello admin!</@shiro.hasAnyRoles>
    hasPermission tag: verify whether the current user has this permission, shiro tag: <shiro :hasPermission name="/order:*"> Order</shiro:hasPermission> ; in freemarker: <@shiro.hasPermission name="/order:*">Order/@shiro.hasPermission> 
    lacksRole tag: Verify that the current user does not Belong to this role, contrary to the hasRole tag, the shiro tag: <shiro:hasRole name=" admin">  Administer the system </shiro:hasRole> ；freemarker中：<@shiro.hasRole name="admin">Hello admin!</@shiro.hasRole> 
    lacksPermission tag: Verify that the current user does not have a certain permission, which is relative to the hasPermission tag, shiro tag: <shiro:lacksPermission name="/order:*"> trade </shiro:lacksPermission> ; in freemarker: <@shiro. lacksPermission name="/order:*">trade</@shiro.lacksPermission>
