springboot集成shiro 实现权限控制（转）
shiro
apache shiro 是一个轻量级的身份验证与授权框架，与spring security 相比较，简单易用，灵活性高，springboot本身是提供了对security的支持，毕竟是自家的东西。springboot暂时没有集成shiro，这得自己配。
shiro 内置过滤器
请看博文：
http://blog.csdn.net/hxpjava1/article/details/7035724
本文实现：
本文实现从数据库读取用户信息，获取当前用户的权限或角色，通过配置文件过滤用户的角色或权限。拥有相应的角色或者相应的权限的用户可以访问相应的url。
数据库设计
1. 添加依赖
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.2.5</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.2.5</version>
</dependency>
<dependency>
<groupId>com.github.theborakompanioni</groupId>
<artifactId>thymeleaf-extras-shiro</artifactId>
<version>1.2.1</version>
</dependency>2. 添加shiro 配置
package com.us.shiro;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.spring.LifecycleBeanPostProcessor;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;

@Configuration
public class ShiroConfiguration {
/**

* 主要是AuthorizingRealm类的子类，以及EhCacheManager类。
*/
@Bean(name = "lifecycleBeanPostProcessor")
public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
return new LifecycleBeanPostProcessor();
}
/**
* HashedCredentialsMatcher，这个类是为了对密码进行编码的，
* 防止密码在数据库里明码保存，当然在登陆认证的时候，
* 这个类也负责对form里输入的密码进行编码。
*/
@Bean(name = "hashedCredentialsMatcher")
public HashedCredentialsMatcher hashedCredentialsMatcher() {
HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
credentialsMatcher.setHashAlgorithmName("MD5");
credentialsMatcher.setHashIterations(2);
credentialsMatcher.setStoredCredentialsHexEncoded(true);
return credentialsMatcher;
}
/**ShiroRealm，这是个自定义的认证类，继承自AuthorizingRealm，

// */

// @DependsOn("lifecycleBeanPostProcessor")
// public EhCacheManager ehCacheManager() {
// return new EhCacheManager();

// */

securityManager.setRealm(shiroRealm());
// securityManager.setCacheManager(ehCacheManager());
return securityManager;
}
/**
* ShiroFilterFactoryBean，是个factorybean，为了生成ShiroFilter。
* 它主要保持了三项数据，securityManager，filters，filterChainDefinitionManager。
*/
@Bean(name = "shiroFilter")
public ShiroFilterFactoryBean shiroFilterFactoryBean() {
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
shiroFilterFactoryBean.setSecurityManager(securityManager());
Map<String, Filter> filters = new LinkedHashMap<>();
LogoutFilter logoutFilter = new LogoutFilter();
logoutFilter.setRedirectUrl("/login");
// filters.put("logout",null);

Map<String, String> filterChainDefinitionManager = new LinkedHashMap<String, String>();
filterChainDefinitionManager.put("/logout", "logout");
filterChainDefinitionManager.put("/user/**", "authc,roles[ROLE_USER]");//用户为ROLE_USER 角色可以访问。由用户角色控制用户行为。
filterChainDefinitionManager.put("/events/**", "authc,roles[ROLE_ADMIN]");
// filterChainDefinitionManager.put("/user/edit/**", "authc,perms[user:edit]");// 这里为了测试，固定写死的值，也可以从数据库或其他配置中读取，此处是用权限控制
filterChainDefinitionManager.put("/**", "anon");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionManager);
shiroFilterFactoryBean.setSuccessUrl("/");
shiroFilterFactoryBean.setUnauthorizedUrl("/403");
return shiroFilterFactoryBean;
}
/**
* DefaultAdvisorAutoProxyCreator，Spring的一个bean，由Advisor决定对哪些类的方法进行AOP代理。
*/
@Bean
@ConditionalOnMissingBean

*/
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor() {

aASA.setSecurityManager(securityManager());
return aASA;
}
}3. 添加Realm 验证
package com.us.shiro;
import com.us.bean.Permission;
import com.us.bean.Role;
import com.us.bean.User;
import com.us.dao.PermissionDao;
import com.us.dao.UserDao;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.PrincipalCollection;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
/**
* Created by cdyoue on 2016/10/21.
*/
public class ShiroRealm extends AuthorizingRealm {
private Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private UserDao userService;
@Autowired
private PermissionDao permissionService;
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
logger.info("doGetAuthorizationInfo+"+principalCollection.toString());
User user = userService.getByUserName((String) principalCollection.getPrimaryPrincipal());
//把principals放session中 key=userId value=principals
SecurityUtils.getSubject().getSession().setAttribute(String.valueOf(user.getId()),SecurityUtils.getSubject().getPrincipals());
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//赋予角色
for(Role userRole:user.getRoles()){
info.addRole(userRole.getName());
}
//赋予权限
for(Permission permission:permissionService.getByUserId(user.getId())){
// if(StringUtils.isNotBlank(permission.getPermCode()))
info.addStringPermission(permission.getName());
}
//设置登录次数、时间
// userService.updateUserLogin(user);
return info;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
logger.info("doGetAuthenticationInfo +" + authenticationToken.toString());
UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
String userName=token.getUsername();
logger.info(userName+token.getPassword());
User user = userService.getByUserName(token.getUsername());
if (user != null) {
// byte[] salt = Encodes.decodeHex(user.getSalt());
// ShiroUser shiroUser=new ShiroUser(user.getId(), user.getLoginName(), user.getName());
//设置用户session
Session session = SecurityUtils.getSubject().getSession();
session.setAttribute("user", user);
return new SimpleAuthenticationInfo(userName,user.getPassword(),getName());
} else {
return null;
}
// return null;
}
}
4. 添加controller
package com.us.controller;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.*;
import java.util.HashMap;
import java.util.Map;
/**
* Created by cdyoue on 2016/10/21.
* 登陆控制器
*/
@RestController
public class LoginController {
private Logger logger = LoggerFactory.getLogger(this.getClass());
@RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(
@RequestParam(value = "username", required = true) String userName,
@RequestParam(value = "password", required = true) String password,
@RequestParam(value = "rememberMe", required = true, defaultValue = "false") boolean rememberMe
) {
logger.info("==========" + userName + password + rememberMe);
Subject subject = SecurityUtils.getSubject();
UsernamePasswordToken token = new UsernamePasswordToken(userName, password);
token.setRememberMe(rememberMe);
try {
subject.login(token);
} catch (AuthenticationException e) {
e.printStackTrace();
// rediect.addFlashAttribute("errorText", "您的账号或密码输入错误!");
return "{\"Msg\":\"您的账号或密码输入错误\",\"state\":\"failed\"}";
}
return "{\"Msg\":\"登陆成功\",\"state\":\"success\"}";
}
@RequestMapping("/")
@ResponseBody
public String index() {
return "no permission";
}
}
此处代码不全，只是写了springboot 整合的主要类，如果需要全部代码请移步。。。
