Spring Security3简单应用(权限设备在文件中)
添加时间:2013-5-10 点击量:1、权限既然写在设备文件中,那么数据库中只须要三个表即可。
1)t_user 用户表
2)t_role 角色表
3)t_user_role 用户角色表
2、对应的范畴实体
1)用户
package cn.luxh.app.domain;
/
用户
@author Luxh
/
public class User {
private Integer id;
/帐号/
private String account;
/暗码/
private String password;
@Override
public int hashCode() {
return account.hashCode();
}
@Override
public boolean equals(Object obj) {
User user = (User) obj;
return this.account.equals(user.getAccount());
}
//getter setter
//...
}2)角色
package cn.luxh.app.domain;
/
角色
@author Luxh
/
public class Role {
private Integer id;
/角色名称/
private String name;
//getter setter
//...
}3)用户-角色
package cn.luxh.app.domain;
/
用户角色
@author Luxh
/
public class UserRole {
private Integer id;
/用户id/
private Integer userId;
/角色id/
private Integer roleId;
//getter setter
//...
}3、设备文件
在web.xml文件中加上如下内容:
<!-- SpringSecurity权限框架 -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>
org.springframework.web.filter.DelegatingFilterProxy
</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>
<!-- 获取Spring Security session的生命周期-->
<listener>
<listener-class>
org.springframework.security.web.session.HttpSessionEventPublisher
</listener-class>
</listener>当然设备spring器的时辰得把springsecurity的权限设备文件给加载进去:
<!-- 设备Spring器 -->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml,classpath:application-security.xml</param-value>
</context-param>权限设备文件内容如下:
<?xml version=1.0 encoding=UTF-8?>

<!-- 登录页面不阻碍 -->

<!-- 资料文件不阻碍 -->
<http pattern=/resources/ security=none />
<http auto-config=true use-expressions=true access-denied-page=/denied>
<!-- default-target-url 指定了从登录页面登录掉队行跳转的页面 always-use-default-target true默示登录成功后强迫跳转
authentication-failure-url 默示验证失败掉队入的页面 login-processing-url 设置验证登录验证地址,若是不设置,默认是j_spring_security_check

default-target-url=/user/home -->
<form-login login-page=/login

<!-- 经管员和通俗用户可以接见 -->

<!-- 经管员和通俗用户可以接见 -->
<intercept-url pattern=/common access=hasAnyRole(ROLE_ADMIN,ROLE_USER) />
<!-- 只有经管员可以接见 -->
<intercept-url pattern=/admin access=hasAnyRole(ROLE_ADMIN) />
<!-- 退出后到登岸页面 -->
<logout logout-success-url=/login />
<!-- error-if-maximum-exceeded 后登岸的账号会挤掉第一次登岸的账号
session-fixation-protection
防止捏造sessionid进击. 用户登录成功后会烧毁用户当前的session.

<session-management invalid-session-url=/login?error=3

</authentication-manager>

<!-- 登录成功营业处理惩罚 -->

</beans:bean>
<!-- 登录失败营业处理惩罚 -->
<beans:bean id=failureHandler class=cn.luxh.app.security.LoginAuthenticationFailureHandler/>
</beans:beans>4、权限设备文件顶用到的类
1)UserDetailsServiceImpl
package cn.luxh.app.security;
import java.util.Collection;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import cn.luxh.app.domain.Role;
import cn.luxh.app.domain.User;
import cn.luxh.app.persistence.RoleMapper;
import cn.luxh.app.persistence.UserMapper;
public class UserDetailsServiceImpl implements UserDetailsService{
private static Logger log = LoggerFactory.getLogger(UserDetailsServiceImpl.class);
@Autowired
private UserMapper userMapper;
@Autowired
private RoleMapper roleMapper;
/
@param account 登录帐号
/
public UserDetails loadUserByUsername(String account)
throws UsernameNotFoundException {
log.info(登录账号:+account);
org.springframework.security.core.userdetails.User userDetails = null;
User user = userMapper.ByAccount(account);
//账号暗码错误,可以在这熟步履抛出异常,让验证失败处理惩罚器AuthenticationFailureHandler进行处理惩罚
Collection<GrantedAuthority> grantedAuthorities = getGrantedAuthorities(user);
boolean enables = true;
boolean accountNonExpired = true;
boolean credentialsNonExpired = true;
boolean accountNonLocked = true;
userDetails = new org.springframework.security.core.userdetails.User(user.getAccount(), user.getPassword(), enables, accountNonExpired, credentialsNonExpired, accountNonLocked, grantedAuthorities);
return userDetails;
}
/
按照用户获取该用户拥有的角色
@param user
@return
/
private Set<GrantedAuthority> getGrantedAuthorities(User user) {
Set<GrantedAuthority> grantedAuthorities = new HashSet<GrantedAuthority>();
List<Role> roles = roleMapper.ByUserId(user.getId());
if(roles != null) {
for(Role role : roles) {
grantedAuthorities.add(new SimpleGrantedAuthority(role.getName()));
}
}
return grantedAuthorities;
}
}UserMapper和RoleMapper是我应用MyBatis接见数据库的接口。
2)LoginAuthenticationSuccessHandler
package cn.luxh.app.security;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
/
登录验证成功处理惩罚器
@author Luxh
/
public class LoginAuthenticationSuccessHandler implements AuthenticationSuccessHandler{
private static Logger log = LoggerFactory.getLogger(LoginAuthenticationSuccessHandler.class);
//登录验证成功后须要跳转的url
private String url;
public void onAuthenticationSuccess(HttpServletRequest request,
HttpServletResponse response, Authentication authentication) throws IOException,
ServletException {
log.info(登录验证成功:+request.getContextPath()+url);
//response.sendRedirect(request.getContextPath()+url);
request.getRequestDispatcher(url).forward(request, response);
}
public void setUrl(String url) {
this.url = url;
}
}3)LoginAuthenticationFailureHandler
package cn.luxh.app.security;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
/
登录验证失足处理惩罚
@author Luxh
/
public class LoginAuthenticationFailureHandler implements AuthenticationFailureHandler {
@Override
public void onAuthenticationFailure(HttpServletRequest request,
HttpServletResponse response, AuthenticationException ae)
throws IOException, ServletException {
//按照AuthenticationException异常的类型
//进行失足营业逻辑处理惩罚
//...
response.sendRedirect(request.getContextPath()+/login);
}
}5、SpringMVC的Controller
1)LoginController
package cn.luxh.app.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
@Controller
public class LoginController {
private static Logger log = LoggerFactory.getLogger(LoginController.class);
/
登录进口
/
@RequestMapping(value={/,/login})
public String login(@RequestParam(required=false) String error) {
log.info(login......);
if(1.equals(error)) {
log.info(验证失败!);
}else if(2.equals(error)) {
log.info(你的帐号已登录,不容许反复登岸!);
}else if(3.equals(error)) {
log.info(会话超时!);
}
return login;
}
/
没有权限接见跳转url
/
@RequestMapping(value=/denied)
public String denied(){
log.info(denied......);
return denied;
}
/
超时跳转url
/
@RequestMapping(value=/timeout)
public String timedout(){
log.info(timeout......);
return timedout;
}
}2)IndexController
package cn.luxh.app.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class IndexController {
private static Logger log = LoggerFactory.getLogger(IndexController.class);
/
经管员和通俗用户可以接见
/
@RequestMapping(value=/index)
public String index(){
log.info(index.......);
return index;
}
/
经管员和通俗用户可以接见
/
@RequestMapping(value=/common)
public String myJsp(){
log.info(common.......);
return common;
}
/
经管员可以接见
/
@RequestMapping(value=/admin)
public String admin(){
log.info(admin.......);
return admin;
}

无论对感情还是对生活,“只要甜不要苦”都是任性而孩子气的,因为我们也不完美,我们也会伤害人。正因为我们都不完美,也因为生活从不是事事如意,所以对这些“瑕疵”的收纳才让我们对生活、对他人的爱变得日益真实而具体。—— 汪冰《世界再亏欠你,也要敢于拥抱幸福》
