shiro集成SSM
1.導入POM文件
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.4.0</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>1.4.0</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.4.0</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.4.0</version>
</dependency>
2. web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<display-name>Archetype Created Web Application</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<--! DelegatingFilterProxy 做用是自動到 Spring容器查找名字爲 shiroFilter（filter-name）
的 bean 並把全部 Filter的操做委託給它 -->
<filter>
<filter-name>shiroFilter</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>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
注：DelegatingFilterProxy的filter-name要和spring-shiro中的shiroFilterFactoryBean中的id相同，不然報錯，或者使用如下方法（在DelegatingFilterProxy中加入<init-param>）java
<filter>
<filter-name>shiroFilter</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>
<init-param>
<param-name>targetBeanName</param-name>
<param-value>name</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
此時spring-shiro中的shiroFilterFactoryBean中的id和param-value相同，即nameweb

4.Controller
@RequestMapping("/doLogin")
public String doLogin(String username, String password) {
System.out.println("doLogin.............");
Subject subject= SecurityUtils.getSubject();
if(!subject.isAuthenticated()){
UsernamePasswordToken token=new UsernamePasswordToken(username,password,true);
try {
subject.login(token);
} catch (AuthenticationException e) {
System.out.println("認證失敗。");
}
}
return "redirect:success";
}
5.realm
public class FirstRealm extends AuthorizingRealm{
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
UsernamePasswordToken uptoken=(UsernamePasswordToken) token;
String username = uptoken.getUsername();
String credentials=null;
if("zhangsan".equals(username)){
credentials="2a0d136ceacafe198ea64ac09daaf1b6";
}else if("lisi".equals(username)){
credentials = "8c702ae443795331c91cfab48f3f3833";
}
ByteSource byteSource=new ByteSource.Util().bytes(username);
AuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(username, credentials, byteSource, getName());
// new SimpleAuthenticationInfo(principal, credentials, credentialsSalt, realmName);
return authenticationInfo;
}
public static void main(String[] args) {
String hashAlgorithmName = "MD5";
Object credentials = "123456";
Object salt = ByteSource.Util.bytes("lisi");;
int hashIterations = 1024;
Object result = new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations);
System.out.println(result);
}
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
System.out.println("FirstRealm..2222.........");
Object primaryPrincipal = principals.getPrimaryPrincipal();
Set<String> roles = new HashSet<>();
if("zhangsan".equals(primaryPrincipal)){
roles.add("user");
roles.add("vip");
}else if("abc".equals(primaryPrincipal)){
roles.add("user");
}
SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
simpleAuthorizationInfo.addRoles(roles);
return simpleAuthorizationInfo;
}
}
public class SecondRealm extends AuthorizingRealm{
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
UsernamePasswordToken uptoken=(UsernamePasswordToken) token;
String username = uptoken.getUsername();
String credentials=null;
if("abc".equals(username)){
credentials="31420b87dd2e42f39d7dc7bdc3a7ee12e4053de8";
}else if("qwe".equals(username)){

ByteSource byteSource=new ByteSource.Util().bytes(username);

// new SimpleAuthenticationInfo(principal, credentials, credentialsSalt, realmName);
return authenticationInfo;
}
public static void main(String[] args) {
String hashAlgorithmName = "SHA1";
Object credentials = "123";
Object salt = ByteSource.Util.bytes("qwe");;
int hashIterations = 1024;
Object result = new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations);
System.out.println(result);
}
@Override

System.out.println("secondRealm...。。。..........");
Object primaryPrincipal = principals.getPrimaryPrincipal();
Set<String> roles = new HashSet<>();
if("zhangsan".equals(primaryPrincipal)){

}
SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo(roles);
return simpleAuthorizationInfo;
}
}
- 自定義的realm繼承AuthorizingRealm就能夠實現認證和受權方法，AuthorizingRealm繼承自AuthenticatingRealm，AuthenticatingRealm中有doGetAuthenticationInfo方法，AuthorizingRealm中有doGetAuthorizationInfo
-
realm的認證策略：算法
- FirstSuccessfulStrategy：只要有一個 Realm 驗證成功便可，只返回第一個 Realm 身份驗證成功的認證信息，其餘的忽略；
- AtLeastOneSuccessfulStrategy：只要有一個Realm驗證成功便可，和FirstSuccessfulStrategy 不一樣，將返回全部Realm身份驗證成功的認證信息；（默認策略）
- AllSuccessfulStrategy：全部Realm驗證成功纔算成功，且返回全部Realm身份驗證成功的認證信息，若是有一個失敗就失敗了。
- 由於緩存：先去第一個realm尋找role，若是第一個realm有放入當前頁面的權限就不繼續訪問下一個realm，當繼續訪問其餘頁面而第一個realm沒有放入當前頁面的role，則去第二個realm尋找。（不會重複訪問，不配置緩存就會重複訪問）
- filterChainDefinitionMap工廠（filterChainDefinitionMap和filterChainDefinitions只能存在一個）
public class FilterChainDefinitionMapFactory {
public LinkedHashMap<String,String> buildFilterChainDefinitionMap(){
LinkedHashMap<String, String> map = new LinkedHashMap<>();
map.put("/doLogin", "anon");
map.put("/logout", "logout");
map.put("/admin", "authc,roles[admin]");
map.put("/user", "roles[user]");
map.put("/test", "user");
map.put("/vip", "user");
map.put("/success", "user");
map.put("/**", "authc");
return map;
}
}
rememberMe功能若是要認證才能夠操做的的除了加權限還要加authc 例如：map.put("/admin", "authc,roles[admin]");不然能夠經過記住我直接訪問/adminspring
shiro權限註解
- @RequiresAuthentication：表示當前Subject已經經過login進行了身份驗證；即 Subject. isAuthenticated() 返回 true
- @RequiresUser：表示當前 Subject 已經身份驗證或者經過記住我登陸的。
- @RequiresGuest：表示當前Subject沒有身份驗證或經過記住我登陸過，便是遊客身份。
- @RequiresRoles(value={「admin」, 「user」}, logical= Logical.AND)：表示當前 Subject 須要角色 admin 和user，@RequiresRoles(value={「admin」, 「user」}, logical= Logical.OR)：表示當前 Subject 須要角色 admin 或user中的其中一個
- @RequiresPermissions (value={「user:a」, 「user:b」}, logical= Logical.OR)：表示當前 Subject 須要權限 user:a 或user:b。
@RequiresRoles(value = {"admin","vip"},logical = Logical.AND)
@RequestMapping(value = {"/testAnnotation2"})
public String testAnnotation2(){
System.out.println("testAnnotation2222。");
return "success";
}
若是要在Controller層使用註解，要在springmvc.xml中添加apache
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
<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>
若是要在service中使用，在spring-shiro中便可緩存
httpsession和SecurityUtils.getSubject().getSession()能夠互相改，能夠在service調用sessioncookie
session也有會話監聽器用於監聽會話建立、過時及中止事件onStart，onStop，onexpirationsession
