我想每個寫項目的人，都肯定會遇到控制權限這個問題.
例如這個這個鏈接只能管理員訪問，那個鏈接丫只能超級管理員訪問等等，實現方式也有多種多樣，控制的粒度也不一樣。
以前剛學的時候，不會框架，大都是手寫注解+過濾器來進行權限的控制，但這樣增加了過濾器的負擔。用起來也會稍微有些麻煩，粒度不太好控制。

用框架的話，就是封裝了更多的操作，讓一切更簡單吧。當然不局限于Security，還有像Shiro安全框架，這兩種非常常見。
一起加油吧！！！
先看個圖舒緩一下，準備開始吧

SpringBoot整合Security實現權限控制框架(案例詳解)

下面就開始吧！！！

一、前言

介紹：

Spring Security是一個能夠為基于Spring的企業應用系統提供聲明式的安全訪問控制解決方案的安全框架。它提供了一組可以在Spring應用上下文中配置的Bean，充分利用了Spring IoC，DI（控制反轉Inversion of Control ,DI:Dependency Injection 依賴注入）和AOP（面向切面編程）功能，為應用系統提供聲明式的安全訪問控制功能，減少了為企業系統安全控制編寫大量重復代碼的工作。

官網：

SpringSecurity 最新

SpringSecurity 5.0.6版本

優缺點：

優點

Spring Boot 官方提供了大量的非常方便的開箱即用的 Starter ，包括 Spring Security 的 Starter ，使得在 Spring Boot 中使用 Spring Security 變得更加容易。
Spring Security功能強大，比較好用。

缺點

Spring Security 是一個重量級的安全管理框架，
Spring Security概念復雜，配置繁瑣（這個確實，沒法逃開）

案例

我們在訪問一個網站時，大都都會設置普通用戶能有的權限，然后管理員有的權限，再就是超級管理員等等，這次就是實現這樣一個案例。

二、環境準備

2.1、數據庫表

CREATE TABLE `account`  (
  `id` int(10) NOT NULL AUTO_INCREMENT,
  `username` varchar(25) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `password` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `role` varchar(25) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 5 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

INSERT INTO `account` VALUES (1, "user", "$2a$10$1MHNdZS.oCICxLRVbnNBZe4CRn9Rk1MVQhasSMhHr0G4BCNQjPpna", "ROLE_USER");
INSERT INTO `account` VALUES (2, "admin", "$2a$10$dKkrkgVzaCPX74TvxOjwNuFJjIRJeAuDPKFntwNwRvRHkwIAHV5Q6", "ROLE_ADMIN");
INSERT INTO `account` VALUES (3, "super_admin", "$2a$10$CqOXnSp6oks9UTvsops4U.0vMGbUE2Bp28xKaPmlug4W8Mk59Sj8y", "ROLE_SUPER_ADMIN");
INSERT INTO `account` VALUES (4, "test", "$2a$10$SQsuH1XfxHdsVmf2nE75wOAE6GHm1nd/xDp/08KYJmtbzJt2J6xIG", "TEST");

        String role = "";
        // 因為在JwtUser中存了權限信息，可以直接獲取，由于只有一個角色就這么干了

        response.setContentType("application/json;charset=utf-8");
        PrintWriter writer = response.getWriter();
        writer.write(new ObjectMapper().writeValueAsString(user));

        PrintWriter writer = response.getWriter();
        writer.write(new ObjectMapper().writeValueAsString( "登錄失敗，賬號或密碼錯誤"));
    }
}

2.6、Security授權

import com.crush.security.utils.JwtTokenUtils;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.web.authentication.www.BasicAuthenticationFilter;

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

/**
 * 處理HTTP請求的BASIC授權標頭，然后將結果放入SecurityContextHolder 。
 */
public class JwtAuthorizationFilter extends BasicAuthenticationFilter {

    public JwtAuthorizationFilter(AuthenticationManager authenticationManager) {
        super(authenticationManager);
    }

    @Override
    protected void doFilterInternal(HttpServletRequest request,
                                    HttpServletResponse response,
                                    FilterChain chain) throws IOException, ServletException {

        String tokenHeader = request.getHeader(JwtTokenUtils.TOKEN_HEADER);
        // 如果請求頭中沒有Authorization信息則直接放行了
        if (tokenHeader == null || !tokenHeader.startsWith(JwtTokenUtils.TOKEN_PREFIX)) {
            chain.doFilter(request, response);
            return;
        }
        // 如果請求頭中有token，則進行解析，并且設置認證信息
        SecurityContextHolder.getContext().setAuthentication(getAuthentication(tokenHeader));
        super.doFilterInternal(request, response, chain);
    }

    /** * 這里從token中獲取用戶信息并新建一個token*/
    private UsernamePasswordAuthenticationToken getAuthentication(String tokenHeader) {
        String token = tokenHeader.replace(JwtTokenUtils.TOKEN_PREFIX, "");
        String username = JwtTokenUtils.getUsername(token.trim());
        String role = JwtTokenUtils.getUserRole(token);
        if (username != null) {
            return new UsernamePasswordAuthenticationToken(username, null,
                    Collections.singleton(new SimpleGrantedAuthority(role))
            );
        }
        return null;
    }
}

2.7、UserDetailsService

UserDetailServiceImpl 實現了UserDetailsService,用來加載用戶特定數據的核心接口。

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.crush.security.entity.MyUser;
import com.crush.security.service.IMyUserService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

@Slf4j
@Service
public class UserDetailServiceImpl implements UserDetailsService {

    final
    IMyUserService userService;

    public UserDetailServiceImpl(IMyUserService userService) {
        this.userService = userService;
    }

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        MyUser user = userService.getOne(new QueryWrapper<MyUser>().eq("username", username));
        return user;
    }
}

2.7、MacLoginUrlAuthenticationEntryPoint

/**
 * 
 * 身份驗證沒有通過回調
 */
@Component
public class MacLoginUrlAuthenticationEntryPoint implements AuthenticationEntryPoint {
    @Override
    public void commence(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AuthenticationException e) throws IOException, ServletException {
        httpServletResponse.setStatus(HttpServletResponse.SC_FORBIDDEN);
        httpServletResponse.setContentType("application/json;charset=utf-8");
        PrintWriter writer = httpServletResponse.getWriter();
        writer.write(new ObjectMapper().writeValueAsString("未登錄！"));
    }
}

2.8、MyAccessDeniedHandler

/**
 * 權限不足回調
 */
@Component
public class MyAccessDeniedHandler implements AccessDeniedHandler {

    @Override
    public void handle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AccessDeniedException e) throws IOException, ServletException {
        httpServletResponse.setContentType("application/json;charset=utf-8");
        httpServletResponse.setStatus(HttpServletResponse.SC_FORBIDDEN);
        PrintWriter writer = httpServletResponse.getWriter();
        writer.write(new ObjectMapper().writeValueAsString("不好意思，你的權限不足！"));
    }
}

2.9、MyLogoutSuccessHandler

/**
 * 退出回調
 */
@Component
public class MyLogoutSuccessHandler implements LogoutSuccessHandler {
    @Override
    public void onLogoutSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
        httpServletResponse.setStatus(HttpServletResponse.SC_OK);
        httpServletResponse.setContentType("application/json;charset=utf-8");
        PrintWriter writer = httpServletResponse.getWriter();
        writer.write(new ObjectMapper().writeValueAsString( "退出成功"));
    }
}

2.10、JWT的工具類

生成token

package com.crush.security.utils;

import io.jsonwebtoken.Claims;
import io.jsonwebtoken.ExpiredJwtException;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

import java.util.Date;
import java.util.HashMap;

public class JwtTokenUtils {

    public static final String TOKEN_HEADER = "Authorization";
    public static final String TOKEN_PREFIX = "Bearer ";

    private static final String SECRET = "jwtsecretdemo";
    private static final String ISS = "echisan";

    /**
     * 過期時間是3600秒，既是1個小時
     */
    private static final long EXPIRATION = 3600L;

    /**
     * 選擇了記住我之后的過期時間為7天
     */
    private static final long EXPIRATION_REMEMBER = 604800L;

    // 添加角色的key
    private static final String ROLE_CLAIMS = "rol";

    /**
     * 修改一下創建token的方法
     *
     * @param username
     * @param role
     * @param isRememberMe
     * @return
     */
    public static String createToken(String username, String role, boolean isRememberMe) {
        String token = null;
        try {
            long expiration = isRememberMe ? EXPIRATION_REMEMBER : EXPIRATION;
            HashMap<String, Object> map = new HashMap<>();
            map.put(ROLE_CLAIMS, role);
            token = Jwts.builder()
                    .signWith(SignatureAlgorithm.HS512, SECRET)
                    // 這里要早set一點，放到后面會覆蓋別的字段
                    .setClaims(map)
                    .setIssuer(ISS)
                    .setSubject(username)
                    .setIssuedAt(new Date())
                    .setExpiration(new Date(System.currentTimeMillis() + expiration * 1000))
                    .compact();
        } catch (ExpiredJwtException e) {
            e.getClaims();
        }
        return token;
    }


    /**
     * 從token中獲取用戶名
     *
     * @param token
     * @return
     */
    public static String getUsername(String token) {
        return getTokenBody(token).getSubject();
    }

    /**
     * 從token中獲取roles
     *
     * @param token
     * @return
     */
    public static String getUserRole(String token) {
        return (String) getTokenBody(token).get(ROLE_CLAIMS);
    }

    /**
     * 是否已過期
     *
     * @param token
     * @return
     */
    public static boolean isExpiration(String token) {
        return getTokenBody(token).getExpiration().before(new Date());
    }

    private static Claims getTokenBody(String token) {
        return Jwts.parser()
                .setSigningKey(SECRET)
                .parseClaimsJws(token)
                .getBody();
    }

    public static void main(String[] args) {
        BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
        String user = encoder.encode("test");
        System.out.println(user);
    }
}

弄完上面這些，相關配置就都搞定了，剩下就是最簡單的編碼啦。

三、代碼 entity

@Data
@EqualsAndHashCode(callSuper = false)
@TableName("account")
public class MyUser implements Serializable, UserDetails {

    private static final long serialVersionUID = 1L;

    private int id;

    private String username;

    private String password;

    // 1:啟用 ， 0：禁用
    @TableField(exist = false)
    private Integer enabled = 1;

    // 1：鎖住 ， 0：未鎖
    @TableField(exist = false)
    private Integer locked = 0;

    private String role;

    @TableField(exist = false)
    private String token;

    //授權
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        List<SimpleGrantedAuthority> authorities = new ArrayList<>();
        SimpleGrantedAuthority authority = new SimpleGrantedAuthority(role);
        authorities.add(authority);
        return authorities;
    }

    @Override
    public boolean isAccountNonExpired() { return true; }
