一、简介

Web应用的安全管理，主要包括两个方面的内容：身份认证、用户授权，此处使用spring-cloud-security来说明。

二、依赖管理


    org.springframework.cloud
    spring-cloud-starter-security


   org.thymeleaf.extras
   thymeleaf-extras-springsecurity4

三、安全策略配置

Spring Security已经大体实现了，我们这里只是需要一些配置与引用。

package com.example.demo.config;

import com.example.demo.utils.security.CustomUserService;

import com.example.demo.utils.security.LoginSuccessHandler;

import com.example.demo.utils.security.MyFilterSecurityInterceptor;

import com.example.demo.utils.security.SecuritySettings;

import org.apache.commons.lang3.StringUtils;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;

import org.springframework.security.config.annotation.web.builders.HttpSecurity;

import org.springframework.security.config.annotation.web.builders.WebSecurity;

import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;

import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

import org.springframework.security.core.userdetails.UserDetailsService;

import org.springframework.security.web.access.intercept.FilterSecurityInterceptor;

import org.springframework.security.web.authentication.AuthenticationSuccessHandler;

import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;

/**

* Security安全配置

*

* @Author: 我爱大金子

* @Description: Security安全配置

* @Date: Create in 15:20 2017/7/5

*/

@Configuration

@EnableWebSecurity

public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired

private CustomFilterSecurityInterceptor customFilterSecurityInterceptor; // 权限管理过滤器

@Autowired

private SecuritySettings securitySettings; // 自定义安全配置类

/**注册UserDetailsService的bean*/

@Bean

public UserDetailsService customUserService(){

return new CustomUserService();

}

/**登录认证*/

@Override

protected void configure(AuthenticationManagerBuilder auth) throws Exception {

auth.userDetailsService(customUserService()); //userDetailsService验证

}

/***设置不拦截规则*/

@Override

public void configure(WebSecurity web) throws Exception {

web.ignoring().antMatchers("/js/**", "/css/**", "/images/**", "/druid/**");

}

/**安全策略配置*/

@Override

protected void configure(HttpSecurity http) throws Exception {

// 设置游客可以访问的URI

if (StringUtils.isNotBlank(securitySettings.getPermitall())) {

http.authorizeRequests().antMatchers(securitySettings.getPermitall().split(",")).permitAll();

}

http.authorizeRequests()

.anyRequest().authenticated() //任何请求,登录后可以访问

// 配置登录URI、登录失败跳转URI与登录成功后默认跳转URI

.and().formLogin().loginPage("/login").failureUrl("/login?error").permitAll().defaultSuccessUrl("/", true).successHandler(loginSuccessHandler())

// 注销行为任意访问

.and().logout().permitAll()

// 设置拒绝访问的提示URI

.and().exceptionHandling().accessDeniedPage("/login?illegal")

;

http.addFilterBefore(myFilterSecurityInterceptor, FilterSecurityInterceptor.class);

}

/**登录成功处理器*/

private AuthenticationSuccessHandler loginSuccessHandler() {

return new LoginSuccessHandler();

}

说明：

loginPage：设置一个实验自定义的登录URI

loginSuccessHandler：设置自定义的登录处理器

permitAll：是允许访问

accessDeniedPage：配置拒绝访问的提示URI

antMatchers：对URI的配置

了解springcloud架构可以加求求：三五三六二四七二五九

假设我要管理员才可以访问admin文件夹下的内容，如：.antMatchers("/admin/**").hasRole("ROLE_ADMIN")，

也可以设置admin文件夹下的文件可以有多个角色来访问，如：.antMatchers("/admin/**").hasAnyRole("ROLE_ADMIN","ROLE_USER")

也可以通过hasIpAddress来指定某一个ip可以访问该资源,写法如下.antMatchers("/admin/**").hasIpAddress("210.210.210.210")

3.1、自定义安全配置类

为是更方便的使用springSecurity，我们自定义一个权限的配置类，如配置登录的URI、游客访问的URI等配置项

package com.example.demo.utils.security;

import org.springframework.boot.context.properties.ConfigurationProperties;

import org.springframework.context.annotation.Configuration;

/**

* 自定义安全配置类

*

* @Author: 我爱大金子

* @Description: 自定义安全配置类

* @Date: Create in 9:45 2017/7/6

*/

@Configuration

@ConfigurationProperties(prefix = "securityConfig")

public class SecuritySettings {

/**允许访问的URL，多个用逗号分隔*/

private String permitall;

public String getPermitall() {

return permitall;

}

public void setPermitall(String permitall) {

this.permitall = permitall;

}

3.2、登录成功处理器

登录成功后，如果需要对用户的行为做一些记录或者执行其它操作，则可以使用登录成功处理器。

package com.example.demo.utils.security;

import com.example.demo.pojo.SysUser;

import org.springframework.security.core.Authentication;

import org.springframework.security.core.userdetails.User;

import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

/**

* 登录成功处理器

*

* @Author: 我爱大金子

* @Description: 登录成功处理器

* @Date: Create in 11:35 2017/7/6

*/

public class LoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {

@Override

public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {

User userDetails = (User) authentication.getPrincipal();

System.out.println("登录用户：username=" + userDetails.getUsername() + ", uri=" + request.getContextPath());

super.onAuthenticationSuccess(request, response, authentication);

}

3.3、springMVC 配置（访问 /login 转向 login.html 页面）

package com.example.demo.config;

import org.springframework.context.annotation.Configuration;

import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

/**

* springMVC 配置（注册访问 /login 转向 login.html 页面）

*

* @Author: 我爱大金子

* @Description: springMVC 配置（注册访问 /login 转向 login.html 页面）

* @Date: Create in 16:24 2017/7/5

*/

@Configuration

public class WebMvcConfig extends WebMvcConfigurerAdapter {

@Override

public void addViewControllers(ViewControllerRegistry registry) {

registry.addViewController("/login").setViewName("login");

}

四、登录认证

在安全策略配置代码中有，主要看自定义的CustomUserService，此类实现了UserDetailsService接口，重写了loadUserByUsername方法

package com.example.demo.utils.security;

import com.example.demo.dao.SysPermissionDao;

import com.example.demo.dao.SysUserDao;

import com.example.demo.pojo.SysPermission;

import org.springframework.security.core.userdetails.User;

import com.example.demo.pojo.SysUser;

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 java.util.ArrayList;

import java.util.List;

/**

* 自定义UserDetailsService,将用户权限交给springsecurity进行管控

*

* @Author: 我爱大金子

* @Description: 将用户权限交给Springsecurity进行管控

* @Date: Create in 16:19 2017/7/5

*/

public class CustomUserService implements UserDetailsService {

@Autowired

private SysUserDao sysUserDao;

@Autowired

private SysPermissionDao sysPermissionDao;

@Override

public UserDetails loadUserByUsername(String username) {

SysUser user = sysUserDao.findByUserName(username);

if (user != null) {

List permissions = sysPermissionDao.findByAdminUserId(user.getId());

List grantedAuthorities = new ArrayList <>();

for (SysPermission permission : permissions) {

if (permission != null && permission.getName()!=null) {

GrantedAuthority grantedAuthority = new SimpleGrantedAuthority(permission.getName());

//1：此处将权限信息添加到 GrantedAuthority 对象中，在后面进行全权限验证时会使用GrantedAuthority 对象。

grantedAuthorities.add(grantedAuthority);

}

return new User(user.getUsername(), user.getPassword(), grantedAuthorities);

} else {

throw new UsernameNotFoundException("admin: " + username + " do not exist!");

}

五、权限管理

在Security安全配置类中使用了权限管理过滤器CustomFilterSecurityInterceptor

package com.example.demo.utils.security;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.security.access.SecurityMetadataSource;

import org.springframework.security.access.intercept.AbstractSecurityInterceptor;

import org.springframework.security.access.intercept.InterceptorStatusToken;

import org.springframework.security.web.FilterInvocation;

import org.springframework.stereotype.Service;

import java.io.IOException;

/**

* 权限管理过滤器

*

* @Author: 我爱大金子

* @Description: 权限管理过滤器

* @Date: Create in 17:16 2017/7/5

*/

@Service

public class CustomFilterSecurityInterceptor extends AbstractSecurityInterceptor implements Filter {

@Autowired

private CustomFilterInvocationSecurityMetadataSource customFilterInvocationSecurityMetadataSource; // 权限配置资源管理器

/**权限管理决断器*/

@Autowired

public void setMyAccessDecisionManager(CustomAccessDecisionManager customAccessDecisionManager) {

super.setAccessDecisionManager(customAccessDecisionManager);

}

@Override

public void init(FilterConfig filterConfig) throws ServletException {

}

@Override

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

FilterInvocation fi = new FilterInvocation(request, response, chain);

invoke(fi);

}

public void invoke(FilterInvocation fi) throws IOException, ServletException {

//fi里面有一个被拦截的url

//里面调用MyInvocationSecurityMetadataSource的getAttributes(Object object)这个方法获取fi对应的所有权限

//再调用MyAccessDecisionManager的decide方法来校验用户的权限是否足够

InterceptorStatusToken token = super.beforeInvocation(fi);

try {

//执行下一个拦截器

fi.getChain().doFilter(fi.getRequest(), fi.getResponse());

} finally {

super.afterInvocation(token, null);

}

@Override

public void destroy() {

}

@Override

public Class getSecureObjectClass() {

return FilterInvocation.class;

}

@Override

public SecurityMetadataSource obtainSecurityMetadataSource() {

return this.customFilterInvocationSecurityMetadataSource;

}

说明：

customFilterSecurityInterceptor：权限管理过滤器

customAccessDecisionManager：权限管理决断器

customFilterInvocationSecurityMetadataSource：权限配置资源管理器

其中过滤器在系统启动时开始工作，并同时导入权限配置资源管理器和权限管理决断器，对用户访问的资源进行管理。权限管理决断器对用户访问的资源与用户拥有的角色权限进行对比，以此来判断用户是否对某个资源具有访问权限。

5.1、权限管理过滤器

继承与AbstractSecurityInterceptor，实时监控用户的行为，防止用户访问未被授权的资源。

package com.example.demo.utils.security;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.security.access.SecurityMetadataSource;

import org.springframework.security.access.intercept.AbstractSecurityInterceptor;

import org.springframework.security.access.intercept.InterceptorStatusToken;

import org.springframework.security.web.FilterInvocation;

import org.springframework.stereotype.Service;

import java.io.IOException;

/**

* 权限管理过滤器

*

* @Author: 我爱大金子

* @Description: 权限管理过滤器

* @Date: Create in 17:16 2017/7/5

*/

@Service

public class CustomFilterSecurityInterceptor extends AbstractSecurityInterceptor implements Filter {

Logger log = LoggerFactory.getLogger(CustomFilterSecurityInterceptor.class);

@Autowired

private CustomFilterInvocationSecurityMetadataSource customFilterInvocationSecurityMetadataSource; // 权限配置资源管理器

/**权限管理决断器*/

@Autowired

public void setMyAccessDecisionManager(CustomAccessDecisionManager customAccessDecisionManager) {

super.setAccessDecisionManager(customAccessDecisionManager);

}

@Override

public void init(FilterConfig filterConfig) throws ServletException {

}

@Override

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

FilterInvocation fi = new FilterInvocation(request, response, chain);

log.info("【权限管理过滤器】请求URL：" + fi.getRequestUrl());

invoke(fi);

}

public void invoke(FilterInvocation fi) throws IOException, ServletException {

//fi里面有一个被拦截的url

//里面调用CustomFilterInvocationSecurityMetadataSource的getAttributes(Object object)这个方法获取fi对应的所有权限

//再调用CustomAccessDecisionManager的decide方法来校验用户的权限是否足够

InterceptorStatusToken token = super.beforeInvocation(fi);

try {

//执行下一个拦截器

fi.getChain().doFilter(fi.getRequest(), fi.getResponse());

} catch(Exception e) {

log.error("【权限管理过滤器】【异常】" + e.getMessage(), e);

} finally {

super.afterInvocation(token, null);

}

@Override

public void destroy() {

}

@Override

public Class getSecureObjectClass() {

return FilterInvocation.class;

}

@Override

public SecurityMetadataSource obtainSecurityMetadataSource() {

return this.customFilterInvocationSecurityMetadataSource;

}

5.2、权限管理决断器

权限管理的关键部分就是决断器，它实现了AccessDecisionManager，重写了decide方法，使用自定义的决断器，在用户访问受保护的资源时，决断器判断用户拥有的角色中是否对改资源具有访问权限，如果没有，则拒绝访问

package com.example.demo.utils.security;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.security.access.AccessDecisionManager;

import org.springframework.security.access.AccessDeniedException;

import org.springframework.security.access.ConfigAttribute;

import org.springframework.security.authentication.InsufficientAuthenticationException;

import org.springframework.security.core.Authentication;

import org.springframework.security.core.GrantedAuthority;

import org.springframework.stereotype.Service;

import java.util.Collection;

import java.util.Iterator;

/**

* 权限管理决断器

*

* @Author: 我爱大金子

* @Description: 权限管理决断器

* @Date: Create in 17:15 2017/7/5

*/

@Service

public class CustomAccessDecisionManager implements AccessDecisionManager {

Logger log = LoggerFactory.getLogger(CustomAccessDecisionManager.class);

// decide 方法是判定是否拥有权限的决策方法，

//authentication 是释CustomUserService中循环添加到 GrantedAuthority 对象中的权限信息集合.

//object 包含客户端发起的请求的requset信息，可转换为 HttpServletRequest request = ((FilterInvocation) object).getHttpRequest();

//configAttributes 为MyInvocationSecurityMetadataSource的getAttributes(Object object)这个方法返回的结果，此方法是为了判定用户请求的url 是否在权限表中，如果在权限表中，则返回给 decide 方法，用来判定用户是否有此权限。如果不在权限表中则放行。

@Override

public void decide(Authentication authentication, Object object, Collection configAttributes) throws AccessDeniedException, InsufficientAuthenticationException {

if(null== configAttributes || configAttributes.size() <=0) {

return;

}

ConfigAttribute c;

String needRole;
