轻松上手SpringBoot+SpringSecurity+JWT实RESTfulAPI权限控制实战

前言

我们知道在项目开发中，后台开发权限认证是非常重要的，springboot 中常用熟悉的权限认证框架有，shiro,还有就是springboot 全家桶的 security当然他们各有各的好处，但是我比较喜欢springboot自带的权限认证框架

<!--springboot 权限认证-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>


与springboot天然集成，功能强大

快速上手

主要实现 Spring Security 的安全认证，结合 RESTful API 的风格，使用无状态的环境。

主要实现是通过请求的 URL ，通过过滤器来做不同的授权策略操作，为该请求提供某个认证的方法，然后进行认证，授权成功返回授权实例信息，供服务调用。

基于Token的身份验证的过程如下:

用户通过用户名和密码发送请求。

程序验证。

程序返回一个签名的token 给客户端。

客户端储存token,并且每次用于每次发送请求。

服务端验证token并返回数据。

每一次请求都需要token，所以每次请求都会去验证用户身份，所以这里必须要使用缓存，

添加Spring Security和JWT依赖项

<!--springboot 权限认证-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<!--jwt 认证-->
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt</artifactId>
</dependency>


生成JWT toke

因为要生成JWT toke 所以就写了一个工具类JwtTokenUtil

package cn.soboys.kmall.security.utils;import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.stereotype.Component;import java.io.Serializable;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import java.util.function.Function;/**
* @author kenx
* @version 1.0
* @date 2021/8/5 22:28
* @webSite https://www.soboys.cn/
*/
@Component
public class JwtTokenUtil implements Serializable { private static final long serialVersionUID = -2550185165626007488L; public static final long JWT_TOKEN_VALIDITY = 7*24*60*60; private String secret="TcUF7CC8T3txmfQ38pYsQ3KY"; public String getUsernameFromToken(String token) {
return getClaimFromToken(token, Claims::getSubject);
} public String generateToken(String username) {
Map<String, Object> claims = new HashMap<>();
return doGenerateToken(claims, username);
} public Boolean validateToken(String token, UserDetails userDetails) {
final String username = getUsernameFromToken(token);
return (username.equals(userDetails.getUsername()) && !isTokenExpired(token));
} public <T> T getClaimFromToken(String token, Function<Claims, T> claimsResolver) {
final Claims claims = getAllClaimsFromToken(token);
return claimsResolver.apply(claims);
} private Claims getAllClaimsFromToken(String token) {
return Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody();
} private Boolean isTokenExpired(String token) {
final Date expiration = getExpirationDateFromToken(token);
return expiration.before(new Date());
} public Date getExpirationDateFromToken(String token) {
return getClaimFromToken(token, Claims::getExpiration);
} private String doGenerateToken(Map<String, Object> claims, String subject) {
return Jwts.builder().setClaims(claims).setSubject(subject).setIssuedAt(new Date(System.currentTimeMillis()))
.setExpiration(new Date(System.currentTimeMillis() + JWT_TOKEN_VALIDITY*1000)).signWith(SignatureAlgorithm.HS512, secret).compact();
}
}

注入数据源

这里我们使用数据库作为权限控制数据保存，所以就要注入数据源，进行权限认证

Spring Security提供了 UserDetailsService接口 用于用户身份认证,和UserDetails实体类，用于保存用户信息，（用户凭证，权限等）

看源码

package org.springframework.security.core.userdetails;public interface UserDetailsService {
UserDetails loadUserByUsername(String var1) throws UsernameNotFoundException;
}


package org.springframework.security.core.userdetails;
public interface UserDetails extends Serializable {
Collection<? extends GrantedAuthority> getAuthorities(); String getPassword(); String getUsername(); boolean isAccountNonExpired(); boolean isAccountNonLocked(); boolean isCredentialsNonExpired(); boolean isEnabled();
}


所以我们分为两步走:

1. 自己的User实体类继承Spring SecurityUserDetails 保存相关权限信息

package cn.soboys.kmall.security.entity;import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import com.fasterxml.jackson.annotation.JsonIgnore;
import lombok.Data;
import lombok.EqualsAndHashCode;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;import java.io.Serializable;
import java.time.LocalDateTime;
import java.util.*;/**
* <p>
* 用户表
* </p>
*
* @author kenx
* @since 2021-08-06
*/
@Data
@EqualsAndHashCode(callSuper = false)
@TableName("t_user")
public class User implements Serializable, UserDetails { private static final long serialVersionUID = 1L; /**
* 用户ID
*/
@TableId(value = "USER_ID", type = IdType.AUTO)
private Long userId; /**
* 用户名
*/
@TableField("USERNAME")
private String username; /**
* 密码
*/
@TableField("PASSWORD")
private String password; /**
* 部门ID
*/
@TableField("DEPT_ID")
private Long deptId; /**
* 邮箱
*/
@TableField("EMAIL")
private String email; /**
* 联系电话
*/
@TableField("MOBILE")
private String mobile; /**
* 状态 0锁定 1有效
*/
@TableField("STATUS")
private String status; /**
* 创建时间
*/
@TableField("CREATE_TIME")
private Date createTime; /**
* 修改时间
*/
@TableField("MODIFY_TIME")
private Date modifyTime; /**
* 最近访问时间
*/
@TableField("LAST_LOGIN_TIME")
private Date lastLoginTime; /**
* 性别 0男 1女 2保密
*/
@TableField("SSEX")
private String ssex; /**
* 是否开启tab，0关闭 1开启
*/
@TableField("IS_TAB")
private String isTab; /**
* 主题
*/
@TableField("THEME")
private String theme; /**
* 头像
*/
@TableField("AVATAR")
private String avatar; /**
* 描述
*/
@TableField("DESCRIPTION")
private String description; @TableField(exist = false)
private List<Role> roles; @TableField(exist = false)
private Set<String> perms; /**
* 用户权限
*
* @return
*/
/*@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
List<GrantedAuthority> auths = new ArrayList<>();
List<Role> roles = this.getRoles();
for (Role role : roles) {
auths.add(new SimpleGrantedAuthority(role.getRolePerms()));
}
return auths;
}*/
@Override
@JsonIgnore
public Collection<? extends GrantedAuthority> getAuthorities() {
List<GrantedAuthority> auths = new ArrayList<>();
Set<String> perms = this.getPerms();
for (String perm : perms) {
//这里perms值如果为空或空字符会报错
auths.add(new SimpleGrantedAuthority(perm));
}
return auths;
} @Override
@JsonIgnore
public boolean isAccountNonExpired() {
return true;
} @Override
@JsonIgnore
public boolean isAccountNonLocked() {
return true;
} @Override
@JsonIgnore
public boolean isCredentialsNonExpired() {
return true;
} @Override
@JsonIgnore
public boolean isEnabled() {
return true;
}
}

注意这里有一个问题 登录用户时，总提示 User account is locked

是因为用户实体类实现UserDetails这个接口时，我默认把所有抽象方法给自动实现了，而自动生成下面这四个方法，默认返回false，

@Override
public boolean isAccountNonExpired() {
return false;
} @Override
public boolean isAccountNonLocked() {
return false;
} @Override
public boolean isCredentialsNonExpired() {
return false;
} @Override
public boolean isEnabled() {
return false;
}


问题原因就在这里，只要把它们的返回值改成true就行。

UserDetails 中几个字段的解释：

//返回验证用户密码,无法返回则NULL

String getPassword();
String getUsername();


账户是否过期,过期无法验证

boolean isAccountNonExpired();


指定用户是否被锁定或者解锁,锁定的用户无法进行身份验证

boolean isAccountNonLocked()；


指示是否已过期的用户的凭据(密码),过期的凭据防止认证

boolean isCredentialsNonExpired();


是否被禁用,禁用的用户不能身份验证

boolean isEnabled();


1. 实现接口中loadUserByUsername方法注入数据验证就可以了

自己IUserService用户接口类继承Spring Security提供了 UserDetailsService接口

public interface IUserService extends IService<User>, UserDetailsService { User getUserByUsername(String username); /* *//**
* 获取用户所有权限
*
* @param username
* @return
*//*
Set<String> getUserPerms(String username);*/}


并且加以实现

@Service
@RequiredArgsConstructor
@Slf4j
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements IUserService {
private final RoleMapper roleMapper; @Override
public User getUserByUsername(String username) {
return this.baseMapper.selectOne(new QueryWrapper<User>().lambda()
.eq(User::getUsername, username));
} /**
* 对用户提供的用户详细信息进行身份验证时
*
* @param username
* @return
* @throws UsernameNotFoundException
*/
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = this.getUserByUsername(username); if (StrUtil.isBlankIfStr(user)) {
throw new UsernameNotFoundException("User not found with username: " + username);
} //获取用户角色信息
List<Role> roles = roleMapper.findUserRolePermsByUserName(username);
user.setRoles(roles); List<String> permList = this.baseMapper.findUserPerms(username); //java8 stream 便利
Set<String> perms = permList.stream().filter(o->StrUtil.isNotBlank(o)).collect(Collectors.toSet());
user.setPerms(perms); //用于添加用户的权限。只要把用户权限添加到authorities 就万事大吉。
// List<SimpleGrantedAuthority> authorities = new ArrayList<>(); //用于添加用户的权限。只要把用户权限添加到authorities 就万事大吉。
/*for (Role role : roles) {
authorities.add(new SimpleGrantedAuthority(role.getRolePerms()));
log.info("loadUserByUsername: " + user);
}*/
//user.setAuthorities(authorities);//用于登录时 @AuthenticationPrincipal 标签取值
return user;
}}


自己实现loadUserByUsername从数据库中验证用户名密码，获取用户角色权限信息

拦截器配置

Spring Security的AuthenticationEntryPoint类，它拒绝每个未经身份验证的请求并发送错误代码401

package cn.soboys.kmall.security.config;import cn.soboys.kmall.common.ret.Result;
import cn.soboys.kmall.common.ret.ResultCode;
import cn.soboys.kmall.common.ret.ResultResponse;
import cn.soboys.kmall.common.utils.ResponseUtil;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.AuthenticationEntryPoint;
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.Serializable;/**

* @webSite https://www.soboys.cn/
* 此类继承Spring Security的AuthenticationEntryPoint类，
* 并重写其commence。它拒绝每个未经身份验证的请求并发送错误代码401。
*/
@Component
public class JwtAuthenticationEntryPoint implements AuthenticationEntryPoint, Serializable { /**
* 此类继承Spring Security的AuthenticationEntryPoint类，并重写其commence。
* 它拒绝每个未经身份验证的请求并发送错误代码401
*
* @param httpServletRequest
* @param httpServletResponse
* @param e
* @throws IOException
* @throws ServletException
*/
@Override
public void commence(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AuthenticationException e) throws IOException, ServletException {
Result result = ResultResponse.failure(ResultCode.UNAUTHORIZED, "请先登录");
ResponseUtil.responseJson(httpServletResponse, result);
}
}


JwtRequestFilter 任何请求都会执行此类检查请求是否具有有效的JWT令牌。如果它具有有效的JWT令牌，则它将在上下文中设置Authentication，以指定当前用户已通过身份验证。

package cn.soboys.kmall.security.config;import cn.soboys.kmall.common.utils.ConstantFiledUtil;
import cn.soboys.kmall.security.service.IUserService;
import cn.soboys.kmall.security.utils.JwtTokenUtil;
import io.jsonwebtoken.ExpiredJwtException;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;
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;/**

* 则它将在上下文中设置Authentication，以指定当前用户已通过身份验证。
*/
@Component
@Slf4j
public class JwtRequestFilter extends OncePerRequestFilter { //用户数据源
private IUserService userService;
//生成jwt 的token
private JwtTokenUtil jwtTokenUtil; public JwtRequestFilter(IUserService userService,JwtTokenUtil jwtTokenUtil) {
this.userService = userService;
this.jwtTokenUtil = jwtTokenUtil;
} @Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
final String requestTokenHeader = request.getHeader(ConstantFiledUtil.AUTHORIZATION_TOKEN); String username = null;
String jwtToken = null;
// JWT Token is in the form "Bearer token". Remove Bearer word and get only the Token
if (requestTokenHeader != null && requestTokenHeader.startsWith("Bearer ")) {
jwtToken = requestTokenHeader.substring(7);
try {
username = jwtTokenUtil.getUsernameFromToken(jwtToken);
} catch (IllegalArgumentException e) {
log.error("Unable to get JWT Token");
} catch (ExpiredJwtException e) {
log.error("JWT Token has expired");
}
} else {
//logger.warn("JWT Token does not begin with Bearer String");
} //Once we get the token validate it.
if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) { UserDetails userDetails = this.userService.loadUserByUsername(username); // if token is valid configure Spring Security to manually set authentication
if (jwtTokenUtil.validateToken(jwtToken, userDetails)) { //保存用户信息和权限信息
UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(
userDetails, null, userDetails.getAuthorities());
usernamePasswordAuthenticationToken
.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
// After setting the Authentication in the context, we specify
// that the current user is authenticated. So it passes the Spring Security Configurations successfully.
SecurityContextHolder.getContext().setAuthentication(usernamePasswordAuthenticationToken);
}
}
filterChain.doFilter(request, response);
}
}

配置Spring Security 配置类SecurityConfig

1. 自定义Spring Security的时候我们需要继承自WebSecurityConfigurerAdapter来完成，相关配置重写对应 方法

2. 此处使用了 BCryptPasswordEncoder 密码加密

3. 通过重写configure方法添加我们自定义的认证方式。
