方法1:项目引用classlibrary,建一个common方法用于公用
方法2:建一个basecontroller:Controller,其余的controller:basecontroller。basecontroller中写公共方法
1.概述现在的项目使用的权限控制系统是spring security 3.因为项目的框架使用spring,就顺便使用了。最近研究了一下spring
side4,推荐使用shiro。照着示例做了一遍。在原有的spring web工程中。步骤如下。
2.引进包,maven设置
[html] view plaincopy
org.apache.shiro
shiro-all
1.2.1
jar
compile
3.实现Controller层
主要是登陆url和几个掩饰url
[java] view plaincopy
@Controller
public class AdminController {
@RequestMapping(value = "/admin/index", method = RequestMethod.GET)
public String index(Model model) {
return "admin/index"
}
@RequestMapping(value = "/admin/login", method = RequestMethod.GET)
public String login(Model model) {
logger.info("login get")
return "admin/login"
}
@RequestMapping(value = "/admin/login", method = RequestMethod.POST)
public String doLogin(Model model) {
logger.info("login post")
return "admin/login"
}
@RequiresRoles("user")
@RequestMapping(value = "/admin/user", method = RequestMethod.GET)
public String shiroUser(Model model) {
return "admin/index"
}
@RequiresRoles("admin")
@RequestMapping(value = "/admin/admin", method = RequestMethod.GET)
public String shiroAdmin(Model model) {
return "admin/index"
}
Logger logger = LoggerFactory.getLogger(AdminController.class)
}
4.实现权限验证
继承shiro的AuthorizingRealm
[java] view plaincopy
public class ShiroDbRealm extends AuthorizingRealm {
protected AccountService accountService
@Autowired
public void setAccountService(AccountService accountService) {
this.accountService = accountService
}
/**
* 授权查询回调函数, 进行鉴权但缓存中无用户的授权信息时调用.
*/
@SuppressWarnings("unused")
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection p)
{
logger.info("授权认证:" + p.getRealmNames())
ShiroUser shiroUser = (ShiroUser) p.getPrimaryPrincipal()
&nbsnbspUser user =
accountService.findUserByLoginName(shiroUser.loginName)
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo()
for (Role role : user.getRoleList()) {
//基于Role的权限信息
info.addRole(role.getName())
//基于Permission的权限信息
info.addStringPermission(role.getPermissions())
}
return info
}
/**
* 认证回调函数,登录时调用.
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(
AuthenticationToken authcToken) throws AuthenticationException {
logger.info("authc pass:")
UsernamePasswordToken token = (UsernamePasswordToken) authcToken
logger.info("authc name:" + token.getUsername())
User user = accountService.findUserByLoginName(token.getUsername())
if (user != null) {
if (user.getStatus().equals("disabled")) {
throw new DisabledAccountException()
}
logger.info("authc name:" + token.getUsername() + " user:"
+ user.getLoginName() + " pwd:" + user.getPassword()
+ "getname:" + getName())
// byte[] salt = Encodes.decodeHex(user.getSalt())
return new SimpleAuthenticationInfo(new ShiroUser(user.getLoginName(),
user.getName()),
user.getPassword(), getName())
}
return null
}
/**
* 自定义Authentication对象,使得Subject除了携带用户的登录名外还可以携带更多信息.
*/
public static class ShiroUser implements Serializable {
private static final long serialVersionUID = -1373760761780840081L
public String loginName
public String name
public ShiroUser(String loginName, String name) {
this.loginName = loginName
this.name = name
}
public String getName() {
return loginName
}
/**
* 本函数输出将作为默认的输出.
*/
@Override
public String toString() {
return loginName
}
/**
* 重载hashCode,只计算loginName
*/
@Override
public int hashCode() {
return Objects.hashCode(loginName)
}
/**
* 重载equals,只计算loginName
*/
@Override
public boolean equals(Object obj) {
if (this == obj)
return true
if (obj == null)
return false
if (getClass() != obj.getClass())
return false
ShiroUser other = (ShiroUser) obj
if (loginName == null) {
if (other.loginName != null)
return false
} else if (!loginName.equals(other.loginName))
return false
return true
}
}
Logger logger = LoggerFactory.getLogger(ShiroDbRealm.class)
}
自定义的类ShiroUser是为了,可以多传输一些内容,供后面验证时使用,例子中只用了一个loginName,一般可以用String
传输就够了。
登陆时用doGetAuthenticationInfo()函数获得相关信息。
登陆后访问url 使用doGetAuthorizationInfo()获得用户的权限。
5.配置文件shiro部分
将controller的url纳入权限验证范围。
[html] view plaincopy
<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-3.2.xsd"
default-lazy-init="true">
Shiro安全配置
/admin/login = authc
/admin/logout = logout
/static/** = anon
/admin/** = authc
主要内容是shiroFilter的定义。
loginUrl:登陆页面,用户登陆不成功,自动返回此页面。
successUrl:登陆成功后跳转此页面
unauthorizedUrl:用户访问无权限的链接时跳转此页面
filterChainDefinitions:设置url的访问权限。anon表示不用验证,都可以访问。anthc:authc filter
监听,不登陆不能访问。logout:logout filter监听。没有列出的常用配置:perms["remote:invoke"] :需要角色romote
和权限invoke才能访问。roles["admin"]需要角色admin才能访问。设置可用“,”隔开,如:
/admin/test = authc,roles[admin]
关于filter的列表:
Filter NameClass
anonorg.apache.shiro.web.filter.authc.AnonymousFilter
