spring-security登录和权限管理

spring security

spring security 主要的两个功能是认证和授权
认证的大概流程：
Username password AuthenticationFilter（自定义usernamepassword拦截器）
UserDetailService （查询用户密码的service接口）
Userdetails (用户类接口)
AuthenticationProvide （为认证管理器AuthenticationManager 提供验证组件AuthenticationProvider）
授权的大概流程：
（extends）AbstractsecurityInterceptor +（implements）Filter（资源访问过滤器，拦截访问请求，封装成安全对象FilterInvocation，调用前两个实例进行鉴权）
FilterInvocationSecurityMetadataSource（自定义权限数据源，提供所有URL资源与对应角色权限的映射集合）
AccessDecisionManager （自定义鉴权管理器，根据URL资源权限和用户角色权限进行鉴权）

用户登陆
会被AuthenticationProcessingFilter拦截，调用AuthenticationManager的实现，而且AuthenticationManager会调用ProviderManager来获取用户验证信息（不同的Provider调用的服务不同，因为这些信息可以是在数据库上，可以是在LDAP服务器上，可以是xml配置文件上等），如果验证通过后会将用户的权限信息封装一个User放到spring的全局缓存SecurityContextHolder中，以备后面访问资源时使用。
访问资源（即授权管理）
访问url时，会通过AbstractSecurityInterceptor拦截器拦截，其中会调用FilterInvocationSecurityMetadataSource的方法来获取被拦截url所需的全部权限，在调用授权管理器AccessDecisionManager，这个授权管理器会通过spring的全局缓存SecurityContextHolder获取用户的权限信息，还会获取被拦截的url和被拦截url所需的全部权限，然后根据所配的策略（有：一票决定，一票否定，少数服从多数等），如果权限足够，则返回，权限不够则报错并调用权限不足页面。

model:
Permission

package com.example.arcgisdemo.model;import com.sun.javafx.beans.IDProperty;import javax.persistence.*;
import java.util.List;@Entity
@Table(name = "SYS_PERMISSION")
public class Permission {@Id@GeneratedValue(strategy = GenerationType.AUTO)@Column(name = "ID")private int id;@Column(name = "NAME")private String name;@Column(name = "DESCRIPTION")private String description;@Column(name = "URL")private String url;@Column(name = "PID")private String pid;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getDescription() {return description;}public void setDescription(String description) {this.description = description;}public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}public String getPid() {return pid;}public void setPid(String pid) {this.pid = pid;}}

User:
这里是在User中实现了UserDetails

}

也可以在页面上设置权限，让没有权限的用户看不到该功能

<div sec:authorize="hasRole('ADMIN')"><!--设置权限--><ul class="layui-nav layui-layout-left"><li class="layui-nav-item"><a href="">控制台</a></li><li class="layui-nav-item"><a href="">管理</a></li><li class="layui-nav-item"><a href="/user">用户</a></li><li class="layui-nav-item"><a href="javascript:;">其它系统</a><dl class="layui-nav-child"><dd><a href="">邮件管理</a></dd><dd><a href="">消息管理</a></dd><dd><a href="">授权管理</a></dd></dl></li></ul></div>

在这里遇到个问题 刚开始的时候没有效果，经过找资料需要将spring 版本降到2.0.7以下
再加上：

<htmlxmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

pom.xml 需要配置secutiry扩展包

<dependency><groupId>org.thymeleaf.extras</groupId><artifactId>thymeleaf-extras-springsecurity4</artifactId><version>3.0.2.RELEASE</version></dependency>
