篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了每天学点Shiro-集成spring相关的知识，希望对你有一定的参考价值。
首先用Maven构建Javaweb工程，然后按下面的步骤进行：
1. 第一步肯定是pom.xml中添加依赖，包括spring,springmvc,shiro
<!-- spring + springmvc--> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <!--shiro--> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-all</artifactId> <version>${shiro.version}</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>net.sf.ehcache</groupId> <artifactId>ehcache-core</artifactId> <version>${ehcache.version}</version> </dependency>
<properties> <spring.version>4.3.11.RELEASE</spring.version> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.12</log4j.version> <shiro.version>1.3.2</shiro.version> <ehcache.version>2.6.11</ehcache.version> </properties>
这里的shiro.version不能为1.4.0，否则会部署一直报错
2. 配置web.xml
<!-- Shiro Filter is defined in the spring application context: --> <filter> <filter-name>shiro-filter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiro-filter</filter-name> <servlet-name>spring-mvc-servlet</servlet-name> </filter-mapping> <!--spring + springmvc--> <servlet> <servlet-name>spring-mvc-servlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>spring-mvc-servlet</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-context.xml</param-value> </context-param>
3. spring-mvc.xml配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <mvc:annotation-driven/> <context:component-scan base-package="com.pawn.shiro.controller"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="redirectContextRelative" value="true"/> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
4. spring-context.xml配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <import resource="spring-context-shiro.xml"/> </beans>
5. spring-context-shiro.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!-- ========================================================= Shiro Core Components - Not Spring Specific ========================================================= --> <!-- Shiro‘s main business-tier object for web-enabled applications (use DefaultSecurityManager instead when there is no web environment)--> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="cacheManager" ref="cacheManager"/> <property name="realm" ref="jdbcRealm"/> </bean> <!-- Let‘s use some enterprise caching support for better performance. You can replace this with any enterprise caching framework implementation that you like (Terracotta+Ehcache, Coherence, GigaSpaces, etc --> <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager"> <!-- Set a net.sf.ehcache.CacheManager instance here if you already have one. If not, a new one will be creaed with a default config: <property name="cacheManager" ref="ehCacheManager"/> --> <!-- If you don‘t have a pre-built net.sf.ehcache.CacheManager instance to inject, but you want a specific Ehcache configuration to be used, specify that here. If you don‘t, a default will be used.:--> <property name="cacheManagerConfigFile" value="classpath:ehcache-config.xml"/> </bean> <!-- Used by the SecurityManager to access security data (users, roles, etc).

6. ehcache-config.xml文件
<!-- ~ Hibernate, Relational Persistence for Idiomatic Java ~ ~ License: GNU Lesser General Public License (LGPL), version 2.1 or later. ~ See the lgpl.txt file in the root directory or <http://www.gnu.org/licenses/lgpl-2.1.html>. --> <ehcache> <!-- Sets the path to the directory where cache .data files are created. If the path is a Java System Property it is replaced by its value in the running VM. The following properties are translated: user.home - User‘s home directory user.dir - User‘s current working directory java.io.tmpdir - Default temp file path --> <diskStore path="java.io.tmpdir"/> <!--Default Cache configuration. These will applied to caches programmatically created through the CacheManager. The following attributes are required for defaultCache: maxInMemory - Sets the maximum number of objects that will be created in memory eternal - Sets whether elements are eternal. If eternal, timeouts are ignored and the element is never expired. timeToIdleSeconds - Sets the time to idle for an element before it expires. Is only used if the element is not eternal. Idle time is now - last accessed time timeToLiveSeconds - Sets the time to live for an element before it expires. Is only used if the element is not eternal. TTL is now - creation time overflowToDisk - Sets whether elements can overflow to disk when the in-memory cache has reached the maxInMemory limit. --> <defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" /> <!--Predefined caches. Add your cache configuration settings here.

On a standard Linux system this will be /tmp" --> <cache name="sampleCache1" maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="300" timeToLiveSeconds="600" overflowToDisk="true" /> <!-- Sample cache named sampleCache2 This cache contains 1000 elements.

They are not expired. --> <cache name="sampleCache2" maxElementsInMemory="1000" eternal="true" timeToIdleSeconds="0" timeToLiveSeconds="0" overflowToDisk="false" /> --> <!-- Place configuration for your caches following --> </ehcache>
7. 生成MyRealm.java文件
public class MyRealm implements Realm { @Override public String getName() { return null; } @Override public boolean supports(AuthenticationToken authenticationToken) { return false; } @Override public AuthenticationInfo getAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { return null; } }
