shiro学习--注解配置文件

之前我们配置shiro的配置文件时，都是通过xml中的bean来配置，今天我们利用Java的注解来实现

创建一个SecurityConfig.java来设置shiro的相关信息，以及实现rememberMe的功能，设置有效的时长

SecurityConfig.java：

import java.util.Collection;
import java.util.HashMap;
import java.util.LinkedHashMap;
import java.util.LinkedList;
import java.util.List;
import java.util.Map;

import javax.servlet.Filter;

import org.apache.shiro.mgt.RememberMeManager;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.realm.Realm;
import org.apache.shiro.session.mgt.SessionManager;
import org.apache.shiro.spring.LifecycleBeanPostProcessor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.filter.authc.AnonymousFilter;
import org.apache.shiro.web.filter.authc.FormAuthenticationFilter;
import org.apache.shiro.web.filter.authc.LogoutFilter;
import org.apache.shiro.web.mgt.CookieRememberMeManager;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.apache.shiro.web.servlet.Cookie;
import org.apache.shiro.web.servlet.SimpleCookie;
import org.apache.shiro.web.session.mgt.ServletContainerSessionManager;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.BeanCreationException;
import org.springframework.context.EnvironmentAware;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;

	    rememberMeManager.setCipherKey(Base64.decode("4AvVhdsgUs0FSA3SDFAdag=="));
            //设置cookie 
            rememberMeManager.setCookie(rememberMeCookie());
	    return rememberMeManager;
	}

	@Bean(name="rememberMeCookie")

	    return realms;
	}

	}

	@Bean(name = "shiroFilter")
	public Filter shiroFilter() {
	    ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
	    shiroFilterFactoryBean.setSecurityManager(securityManager());
            //设置登录url，通过environment这个类来实现从properties文件中读取相关的配置
	    shiroFilterFactoryBean.setLoginUrl(env.getProperty("loginURL"));
            //设置登录成功的url
            shiroFilterFactoryBean.setSuccessUrl(env.getProperty("successURL"));
            //设置没通过验证的url
            shiroFilterFactoryBean.setUnauthorizedUrl(env.getProperty("unauthorizedURL"));

	    Map filters = new HashMap();
	    filters.put("anon", new AnonymousFilter());
	    FormAuthenticationFilter formFilter = new FormAuthenticationFilter();
	    formFilter.setRememberMeParam("rememberMe");

		return (Filter) shiroFilterFactoryBean.getObject();
            } catch (Exception ex) {
		throw new BeanCreationException("shiroFilter", "FactoryBean throw exception on object creation", ex);
	}
    }
}

注意：

     1.在shiro验证用到的实体类一定要注意检查是否已序列化，实现java.io.Serializable，因为如果没有序列化，则会在shiro对其进行持久化时会出错，这个错如果没有注意会后面遇到问题时会较为难找

    出现错误的地方是：shiro包中的org.apache.shiro.io.DefaultSerializer接口中，如下：

    2.在shiro用到的实体类中包含其他的实体也得注意，也要将其序列化，不然也会出现同样的错误
