spring boot 集成shiro的配置

        spring boot提供了一个自带的认证框架，同时也提供自定义的javaconfig配置扩展，spring-sercurity同样也是优秀的框架，但是习惯了用apache shiro框架，而且原项目就是集成的shiro框架，到网上找了一下配置方式，没找到完全配置的方法，因此决定自己动手，丰衣足食！

        要在spring boot上集成其他框架，首先要会spring javaconfig方法，利用此方法同样可以配置其他模块，废话少说，开始。。。

        开始前需要导入maven依赖（shiro-web可选）：

                <dependency>
			<groupId>org.apache.shiro</groupId>
			<artifactId>shiro-core</artifactId>
			<version>${shiro.version}</version>
		</dependency>
		<dependency>
			<groupId>org.apache.shiro</groupId>
			<artifactId>shiro-web</artifactId>
			<version>${shiro.version}</version>
		</dependency>
		<dependency>
			<groupId>org.apache.shiro</groupId>
			<artifactId>shiro-spring</artifactId>
			<version>${shiro.version}</version>
		</dependency>
		<dependency>
			<groupId>org.apache.shiro</groupId>
			<artifactId>shiro-ehcache</artifactId>
			<version>${shiro.version}</version>
		</dependency>

        原shiro集成spring的配置拿出来，如下：

/sa/** = authc
/** = anon
</value>
</property>
</bean>
<!-- 用户授权/认证信息Cache, 采用EhCache 缓存 -->
<bean id="shiroEhcacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManagerConfigFile" value="classpath:ehcache-shiro.xml" />
</bean>
<!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />
<!-- AOP式方法级权限检查 -->
<!-- Enable Shiro Annotations for Spring-configured beans. Only run after -->
<!-- the lifecycleBeanProcessor has run: -->
<bean
class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
depends-on="lifecycleBeanPostProcessor">
<property name="proxyTargetClass" value="true" />
</bean>
<bean
class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager" />
</bean>
</beans> 

好多类啊，没办法一个一个配置，javaconfig文件如下：

import java.util.LinkedHashMap;
import java.util.Map;

import org.apache.shiro.cache.ehcache.EhCacheManager;
import org.apache.shiro.spring.LifecycleBeanPostProcessor;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class ShiroConfiguration {

	private static Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();

	@Bean(name = "ShiroRealmImpl")
	public ShiroRealmImpl getShiroRealm() {
		return new ShiroRealmImpl();
	}

	@Bean(name = "shiroEhcacheManager")
	public EhCacheManager getEhCacheManager() {
		EhCacheManager em = new EhCacheManager();
		em.setCacheManagerConfigFile("classpath:ehcache-shiro.xml");
		return em;
	}

	@Bean(name = "lifecycleBeanPostProcessor")
	public LifecycleBeanPostProcessor getLifecycleBeanPostProcessor() {
		return new LifecycleBeanPostProcessor();
	}

	@Bean
	public DefaultAdvisorAutoProxyCreator getDefaultAdvisorAutoProxyCreator() {
		DefaultAdvisorAutoProxyCreator daap = new DefaultAdvisorAutoProxyCreator();
		daap.setProxyTargetClass(true);
		return daap;
	}

	@Bean(name = "securityManager")
	public DefaultWebSecurityManager getDefaultWebSecurityManager() {
		DefaultWebSecurityManager dwsm = new DefaultWebSecurityManager();
		dwsm.setRealm(getShiroRealm());
		dwsm.setCacheManager(getEhCacheManager());
		return dwsm;
	}

	@Bean
	public AuthorizationAttributeSourceAdvisor getAuthorizationAttributeSourceAdvisor() {
		AuthorizationAttributeSourceAdvisor aasa = new AuthorizationAttributeSourceAdvisor();
		aasa.setSecurityManager(getDefaultWebSecurityManager());
		return new AuthorizationAttributeSourceAdvisor();
	}

	@Bean(name = "shiroFilter")
	public ShiroFilterFactoryBean getShiroFilterFactoryBean() {
		ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
		shiroFilterFactoryBean
				.setSecurityManager(getDefaultWebSecurityManager());
		shiroFilterFactoryBean.setLoginUrl("/login");
		shiroFilterFactoryBean.setSuccessUrl("/sa/index");
		filterChainDefinitionMap.put("/sa/**", "authc");
		filterChainDefinitionMap.put("/**", "anon");
		shiroFilterFactoryBean
				.setFilterChainDefinitionMap(filterChainDefinitionMap);
		return shiroFilterFactoryBean;
	}

}

注意点：最后一个是filterChainDefinitionMap的初始化，Map用的是LinkedHashMap来初始化的，各位应用的时候将其配置成properties文件，然后初始化就ok了，改写好后直接启动Ok，搬运到spring boot应该是OK的。

别忘了在ehcache-shiro.xml

<ehcache updateCheck="false" name="shiroCache">

    <defaultCache
            maxElementsInMemory="10000"
            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            overflowToDisk="false"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"
            />
</ehcache>

备注：ShiroRealmImpl类请参考官方文档
