SpringSecurity配置,简单梳理

生活加油:摘一句子:

“我希望自己能写这样的诗。我希望自己也是一颗星星。如果我会发光，就不必害怕黑暗。如果我自己是那么美好，那么一切恐惧就可以烟消云散。于是我开始存下了一点希望—如果我能做到，那么我就战胜了寂寞的命运。”

嗯,刚学的时候,一大堆,明白是配置了啥,不知道为啥那么配,嗯,今天把配置思想和小伙伴分享,是很简单的那种,不足之处请留言.

SpringSecurity的配置基于WebSecurityConfigurerAdapter的实现类,我们这里主要讲基本配置,即configure(HttpSecurity http)方法的配置,其实大都有默认值,我们可以直接用默认值,也可以自己设置.

私以为简单配置三点:

• 认证(SpringSecurity在第一次登录做认证,这时候只进行认证,不进行授权(鉴权处理))
• 表单认证:涉及到的配置包括前端登录请求的url,登录失败,登录成功返回的页面url,已及表单返回字段的用户名密码K的设置,还有登陆成功回调处理和登录失败回调处理.这里要注意登录数据是通过key/value的形式来传递.
• 自定义认证,(验证码):自定义验证采用,在自定义过滤器的方式,在最开始插入一个过滤器链,需要自定义异常,自定义失败登录失败处理器,注意这里的失败处理器要和表单登录使用同一个失败处理器.
• 授权(基于RBAC权限控制):
  • 授权这样分析基于RBAC的权限控制,即用户分配角色,角色分配权限.需要配置根据访问路径得到需要的角色的处理类(FilterlnvocationSecurityrMetadataSource),根据返回角色进行鉴权处理类(AccessDecisionManager) , 同时判断是否登录,还需要配置认证失败的处理器.
• 注销登录
  • 注销登录默认的url为"/logout".需要配置,注销登录处理器

 下面就上面讲的代码分析

一．认证:

１．configure(HttpSecurity http)方法的配置:

    }
    @Bean

    }
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(hrService);
    }
    /**
     * @Author Liruilong
     * @Description  放行的请求路径
     * @Date 19:25 2020/2/7
     * @Param [web]
     * @return void
     **/
    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/auth/code","/login","/css/**","/js/**", "/index.html", "/img/**", "/fonts/**","/favicon.ico");
    }
}

２.失败处理器定义:

package com.liruilong.hros.config;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.liruilong.hros.Exception.ValidateCodeException;
import com.liruilong.hros.model.RespBean;
import org.springframework.context.annotation.Bean;
import org.springframework.security.authentication.*;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

/**
 * @Description :
 * @Author: Liruilong
 * @Date: 2020/2/11 23:08
 */
@Component
public class MyAuthenticationFailureHandler implements AuthenticationFailureHandler {
    @Override
    public void onAuthenticationFailure(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AuthenticationException e) throws IOException, ServletException {
        httpServletResponse.setContentType("application/json;charset=utf-8");
        PrintWriter out = httpServletResponse.getWriter();
        RespBean respBean = RespBean.error(e.getMessage());
           // 验证码自定义异常的处理
        if (e instanceof ValidateCodeException){
            respBean.setMsg(e.getMessage());
            //Security内置的异常处理
        }else if (e instanceof LockedException) {
            respBean.setMsg("账户被锁定请联系管理员!");
        } else if (e instanceof CredentialsExpiredException) {
            respBean.setMsg("密码过期请联系管理员!");
        } else if (e instanceof AccountExpiredException) {
            respBean.setMsg("账户过期请联系管理员!");
        } else if (e instanceof DisabledException) {
            respBean.setMsg("账户被禁用请联系管理员!");
        } else if (e instanceof BadCredentialsException) {
            respBean.setMsg("用户名密码输入错误,请重新输入!");
        }
        //将hr转化为Sting
        out.write(new ObjectMapper().writeValueAsString(respBean));
        out.flush();
        out.close();
    }
    @Bean
    public  MyAuthenticationFailureHandler getMyAuthenticationFailureHandler(){
        return new MyAuthenticationFailureHandler();
    }
}

3.前端将JSON数据转换为K-V形式:

//post请求的封装K-v形式
let base = '';
export const postKeyValueRequest = (url, params) => {
    return axios({
        method: 'post',
        url: `${base}${url}`,
        data: params,
        transformRequest: [function (data) {
            let ret = ''
            for (let it in data) {
                ret += encodeURIComponent(it) + '=' + encodeURIComponent(data[it]) + '&'
            }

            return ret
        }],
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded',
        }
    });
}

4.自定义过滤器:

package com.liruilong.hros.filter;

import com.liruilong.hros.Exception.ValidateCodeException;
import com.liruilong.hros.config.MyAuthenticationFailureHandler;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.core.AuthenticationException;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**
 * @Description :
 * @Author: Liruilong
 * @Date: 2020/2/7 19:39
 */
@Component
public class VerifyCodeFilter extends OncePerRequestFilter {

    @Bean
    public VerifyCodeFilter getVerifyCodeFilter() {
        return new VerifyCodeFilter();
    }
    @Autowired
    MyAuthenticationFailureHandler myAuthenticationFailureHandler;
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {

        if (StringUtils.equals("/doLogin", request.getRequestURI())
                && StringUtils.equalsIgnoreCase(request.getMethod(), "post")) {
            // 1. 进行验证码的校验
            try {
            String requestCaptcha = request.getParameter("code");
                if (requestCaptcha == null) {
                    throw new ValidateCodeException("验证码不存在");
                }
            String code = (String) request.getSession().getAttribute("yanzhengma");
                if (StringUtils.isBlank(code)) {
                    throw new ValidateCodeException("验证码过期！");
                }
            code = code.equals("0.0") ? "0" : code;
            logger.info("开始校验验证码，生成的验证码为：" + code + " ，输入的验证码为：" + requestCaptcha);
                if (!StringUtils.equals(code, requestCaptcha)) {
                    throw new ValidateCodeException("验证码不匹配");
                }
            } catch (AuthenticationException e) {
                // 2. 捕获步骤1中校验出现异常，交给失败处理类进行进行处理
                myAuthenticationFailureHandler.onAuthenticationFailure(request, response, e);
            } finally {
                filterChain.doFilter(request, response);
            }
        } else {
            filterChain.doFilter(request, response);
        }

    }

}

5.自定义异常:

package com.liruilong.hros.Exception;

import org.springframework.security.core.AuthenticationException;

/**
 * @Description :
 * @Author: Liruilong
 * @Date: 2020/2/8 7:24
 */

public class ValidateCodeException extends AuthenticationException  {

    public ValidateCodeException(String msg) {
        super(msg);
    }

}

 二．授权:

RBAC模型实体图

１．开发者自定义 FilterlnvocationSecurityrMetadataSource

package com.liruilong.hros.config;

import com.liruilong.hros.mapper.MenuMapper;
import com.liruilong.hros.model.Menu;
import com.liruilong.hros.model.Role;
import com.liruilong.hros.service.MenuService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.ConfigAttribute;
import org.springframework.security.access.SecurityConfig;
import org.springframework.security.web.FilterInvocation;
import org.springframework.security.web.access.intercept.FilterInvocationSecurityMetadataSource;
import org.springframework.stereotype.Component;
import org.springframework.util.AntPathMatcher;

import java.util.Collection;
import java.util.List;

/**
 * @Description : 权限处理,根据请求,分析需要的角色,该类的主要功能就是通过当前的请求地址，获取该地址需要的用户角色
 * @Author: Liruilong
 * @Date: 2019/12/24 12:17
 */
@Component
public class CustomFilterInvocationSecurityMetadataSource implements FilterInvocationSecurityMetadataSource {
    @Autowired
    MenuService menuService;
    //路径比较工具
    AntPathMatcher antPathMatcher = new AntPathMatcher();
    /**
     * @return java.util.Collection<org.springframework.security.access.ConfigAttribute>

     * @Param [object]
     **/
    @Override
    public Collection<ConfigAttribute> getAttributes(Object object) throws IllegalArgumentException {
        //获取当前请求路径
        String requestUrl = ((FilterInvocation) object).getRequestUrl();
        //获取所有的菜单url路径
        List<Menu> menus = menuService.getAllMenusWithRole();
        for (Menu menu : menus) {
            if (antPathMatcher.match(menu.getUrl(), requestUrl)) {
                //拥有当前菜单权限的角色
                List<Role> roles = menu.getRoles();
                String[] strings = new String[roles.size()];
                for (int i = 0; i < roles.size(); i++) {
                    strings[i] = roles.get(i).getName();
                }
                return SecurityConfig.createList(strings);
            }
        }
        // 没匹配上的资源都是登录
        return SecurityConfig.createList("ROLE_LOGIN");
    }
    @Override
    public Collection<ConfigAttribute> getAllConfigAttributes() {
        return null;
    }

    @Override
    public boolean supports(Class<?> clazz) {
        return true;
    }
}

２.自定义 AccessDecisionManager

package com.liruilong.hros.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.AccessDecisionManager;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.access.ConfigAttribute;
import org.springframework.security.authentication.AnonymousAuthenticationToken;
import org.springframework.security.authentication.InsufficientAuthenticationException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.stereotype.Component;

import java.util.Collection;

/**
 * @Description : 判断当前用户是否具备菜单访问，当一个请求走完 FilterlnvocationSecurityMetadataSource 中的 getAttributes 方法后，接下来就会 来到 AccessDecisionManager 类中进行角色信息的比对
 * @Author: Liruilong
 * @Date: 2019/12/24 19:12
 */
@Component
public class CustomUrlDecisionManager implements AccessDecisionManager {

    /**
     * @return void
     * @Author Liruilong
     * @Description decide 方法有三个参数， 第一个参数包含当前登录用户的信息；
     * 第二个参数则是一个 Filterlnvocation 对 象 ，可以 获 取当前请求对 象等；
     * 第 三个参 数就是 FilterlnvocationSecurityMetadataSource 中的 getAttributes 方法的返回值， 即当前请求 URL 所 需要的角色。
     * @Date 18:28 2020/2/13
     * @Param [authentication, object, configAttributes]
     **/

    @Override
    public void decide(Authentication authentication, Object object, Collection<ConfigAttribute> configAttributes)
            throws AccessDeniedException, InsufficientAuthenticationException {
        for (ConfigAttribute configAttribute : configAttributes) {
            String needRole = configAttribute.getAttribute();
            if ("ROLE_LOGIN".equals(needRole)) {
                //判断用户是否登录
                if (authentication instanceof AnonymousAuthenticationToken) {
                    throw new AccessDeniedException("尚未登录，请登录!");
                } else {
                    return;
                }
            }
            Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();
            for (GrantedAuthority authority : authorities) {
                if (authority.getAuthority().equals(needRole)) {
                    return;
                }
            }
        }
        throw new AccessDeniedException("权限不足，请联系管理员!");
    }

    @Override
    public boolean supports(ConfigAttribute attribute) {
        return true;
    }

    @Override
    public boolean supports(Class<?> clazz) {
        return true;
    }
}
// authorities.stream().anyMatch((authority) ->authority.getAuthority().equals(attribute));

RBAC模型分析

３. 当然还需要用户类去实现UserDatails接口

package com.liruilong.hros.model;

import com.fasterxml.jackson.annotation.JacksonInject;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonIgnoreType;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

public class Hr implements UserDetails {
    private Integer id;

    private String name;

    private String phone;

    private String telephone;

    private String address;

    private Boolean enabled;

    private String username;

    private String password;

    private String userface;

    private String remark;

    private List<Role> roles;

    public Integer getId() {
        return id;
