一、Spring Security介绍
1、框架介绍
Spring 是一个非常流行和成功的 Java 应用开发框架。Spring Security 基于 Spring 框架，提供了一套 Web 应用安全性的完整解决方案。一般来说，Web 应用的安全性包括用户认证（Authentication）和用户授权（Authorization）两个部分。
（1）用户认证指的是：验证某个用户是否为系统中的合法主体，也就是说用户能否访问该系统。用户认证一般要求用户提供用户名和密码。系统通过校验用户名和密码来完成认证过程。
（2）用户授权指的是验证某个用户是否有权限执行某个操作。在一个系统中，不同用户所具有的权限是不同的。比如对一个文件来说，有的用户只能进行读取，而有的用户可以进行修改。一般来说，系统会为不同的用户分配不同的角色，而每个角色则对应一系列的权限。
Spring Security其实就是用filter，多请求的路径进行过滤。
（1）如果是基于Session，那么Spring-security会对cookie里的sessionid进行解析，找到服务器存储的sesion信息，然后判断当前用户是否符合请求的要求。
（2）如果是token，则是解析出token，然后将当前请求加入到Spring-security管理的权限信息中去
2、认证与授权实现思路
如果系统的模块众多，每个模块都需要就行授权与认证，所以我们选择基于token的形式进行授权与认证，用户根据用户名密码认证成功，然后获取当前用户角色的一系列权限值，并以用户名为key，权限列表为value的形式存入redis缓存中，根据用户名相关信息生成token返回，浏览器将token记录到cookie中，每次调用api接口都默认将token携带到header请求头中，Spring-security解析header头获取token信息，解析token获取当前用户名，根据用户名就可以从redis中获取权限列表，这样Spring-security就能够判断当前请求是否有权限访问
二、整合Spring Security
1、在common下创建spring_security模块
2、在spring_security引入相关依赖
com.royal
common_utils
0.0.1-SNAPSHOTorg.springframework.boot
spring-boot-starter-security
io.jsonwebtoken
jjwt
3、在service_acl引入spring_security依赖
com.royal
spring_security
0.0.1-SNAPSHOT
代码结构说明：
serurity
----config
--------TokenWebSecurityConfig #核心配置类
----entity
--------SecurityUser #相关实体类
--------User
----filter
--------TokenAuthenticationFilter #授权过滤
--------TokenLoginFilter #认证过滤器
----security
--------DefaultPasswordEncoder #密码处理
--------TokenLogoutHandler #退出处理器
--------TokenManager #token操作工具类
--------UnauthorizedEntryPoint #未授权統-处理类
4、创建spring security核心配置类
Spring Security的核心配置就是继承WebSecurityConfigurerAdapter并注解@EnableWebSecurity的配置。
这个配置指明了用户名密码的处理方式、请求路径的开合、登录登出控制等和安全相关的配置
import com.royal.serurity.filter.TokenAuthenticationFilter;
import com.royal.serurity.filter.TokenLoginFilter;
import com.royal.serurity.security.DefaultPasswordEncoder;
import com.royal.serurity.security.TokenLogoutHandler;
import com.royal.serurity.security.TokenManager;
import com.royal.serurity.security.UnauthorizedEntryPoint;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
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;
/**
*
* Security配置类
*
*/
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class TokenWebSecurityConfig extends WebSecurityConfigurerAdapter {
private UserDetailsService userDetailsService;
private TokenManager tokenManager;
private DefaultPasswordEncoder defaultPasswordEncoder;
private RedisTemplate redisTemplate;
@Autowired
public TokenWebSecurityConfig(UserDetailsService userDetailsService, DefaultPasswordEncoder defaultPasswordEncoder,
TokenManager tokenManager, RedisTemplate redisTemplate) {
this.userDetailsService = userDetailsService;
this.defaultPasswordEncoder = defaultPasswordEncoder;
this.tokenManager = tokenManager;
this.redisTemplate = redisTemplate;
}
/**
* 配置设置
* @param http
* @throws Exception
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
http.exceptionHandling()
.authenticationEntryPoint(new UnauthorizedEntryPoint())
.and().csrf().disable()
.authorizeRequests()
.anyRequest().authenticated()
.and().logout().logoutUrl("/admin/acl/index/logout")
.addLogoutHandler(new TokenLogoutHandler(tokenManager,redisTemplate)).and()
.addFilter(new TokenLoginFilter(authenticationManager(), tokenManager, redisTemplate))
.addFilter(new TokenAuthenticationFilter(authenticationManager(), tokenManager, redisTemplate)).httpBasic();
}
/**
* 密码处理
* @param auth
* @throws Exception
*/
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(defaultPasswordEncoder);
}
/**
* 配置哪些请求不拦截
* @param web
* @throws Exception
*/
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/api/**",
"/swagger-resources/**", "/webjars/**", "/v2/**", "/swagger-ui.html/**"
);
}
}
5、创建认证授权相关的工具类
（1）DefaultPasswordEncoder：密码处理的方法
package com.royal.serurity.security;
import com.royal.commonutils.utils.MD5;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;
/**
*
* 密码的处理方法类型
*
*/
@Component
public class DefaultPasswordEncoder implements PasswordEncoder {
public DefaultPasswordEncoder() {
this(-1);
}
/**
* @param strength
* the log rounds to use, between 4 and 31
*/
public DefaultPasswordEncoder(int strength) {
}
public String encode(CharSequence rawPassword) {
return MD5.encrypt(rawPassword.toString());
}
public boolean matches(CharSequence rawPassword, String encodedPassword) {
return encodedPassword.equals(MD5.encrypt(rawPassword.toString()));
}
}
（2）TokenManager：token操作的工具类
import io.jsonwebtoken.CompressionCodecs;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.springframework.stereotype.Component;
import java.util.Date;
/**
*
* token管理
*
*/
@Component
public class TokenManager {
private long tokenExpiration = 24*60*60*1000;
private String tokenSignKey = "123456";
public String createToken(String username) {
String token = Jwts.builder().setSubject(username)
.setExpiration(new Date(System.currentTimeMillis() + tokenExpiration))
.signWith(SignatureAlgorithm.HS512, tokenSignKey).compressWith(CompressionCodecs.GZIP).compact();
return token;
}
public String getUserFromToken(String token) {
String user = Jwts.parser().setSigningKey(tokenSignKey).parseClaimsJws(token).getBody().getSubject();
return user;
}
public void removeToken(String token) {
//jwttoken无需删除，客户端扔掉即可。
}
}
（3）TokenLogoutHandler：退出实现
import com.royal.commonutils.R;
import com.royal.commonutils.utils.ResponseUtil;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.logout.LogoutHandler;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
*
* 登出业务逻辑类
*
*/
public class TokenLogoutHandler implements LogoutHandler {
private TokenManager tokenManager;
private RedisTemplate redisTemplate;
public TokenLogoutHandler(TokenManager tokenManager, RedisTemplate redisTemplate) {
this.tokenManager = tokenManager;
this.redisTemplate = redisTemplate;
}
@Override
public void logout(HttpServletRequest request, HttpServletResponse response, Authentication authentication) {
String token = request.getHeader("token");
if (token != null) {
tokenManager.removeToken(token);
//清空当前用户缓存中的权限数据
String userName = tokenManager.getUserFromToken(token);
redisTemplate.delete(userName);
}
ResponseUtil.out(response, R.ok());
}
}
（4）UnauthorizedEntryPoint：未授权统一处理
import com.royal.commonutils.R;
import com.royal.commonutils.utils.ResponseUtil;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.AuthenticationEntryPoint;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
*
* 未授权的统一处理方式
*
*/
public class UnauthorizedEntryPoint implements AuthenticationEntryPoint {
@Override
public void commence(HttpServletRequest request, HttpServletResponse response,
AuthenticationException authException) throws IOException, ServletException {
ResponseUtil.out(response, R.error());
}
}
6、创建认证授权实体类
（1）SecutityUser
import lombok.Data;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.util.StringUtils;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
/**
*
* 安全认证用户详情信息
*
*/
@Data
@Slf4j
public class SecurityUser implements UserDetails {
//当前登录用户
private transient User currentUserInfo;
//当前权限
private List permissionValueList;
public SecurityUser() {
}
public SecurityUser(User user) {
if (user != null) {
this.currentUserInfo = user;
}
}
@Override
public Collection extends GrantedAuthority> getAuthorities() {
Collection authorities = new ArrayList();
for(String permissionValue : permissionValueList) {
if(StringUtils.isEmpty(permissionValue)) continue;
SimpleGrantedAuthority authority = new SimpleGrantedAuthority(permissionValue);
authorities.add(authority);
}
return authorities;
}
@Override
public String getPassword() {
return currentUserInfo.getPassword();
}
@Override
public String getUsername() {
return currentUserInfo.getUsername();
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return true;
}
}
(2）User
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import java.io.Serializable;
/**
*
* 用户实体类
*
*/
@Data
@ApiModel(description = "用户实体类")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
@ApiModelProperty(value = "微信openid")
private String username;
@ApiModelProperty(value = "密码")
private String password;
@ApiModelProperty(value = "昵称")
private String nickName;
@ApiModelProperty(value = "用户头像")
private String salt;
@ApiModelProperty(value = "用户签名")
private String token;
}
7、创建认证和授权的filter
（1）TokenLoginFilter：认证的filter

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.ArrayList;
/**
*
* 登录过滤器，继承UsernamePasswordAuthenticationFilter，对用户名密码进行登录校验
*
*/
public class TokenLoginFilter extends UsernamePasswordAuthenticationFilter {
private AuthenticationManager authenticationManager;
private TokenManager tokenManager;
private RedisTemplate redisTemplate;
public TokenLoginFilter(AuthenticationManager authenticationManager, TokenManager tokenManager, RedisTemplate redisTemplate) {
this.authenticationManager = authenticationManager;
this.tokenManager = tokenManager;
this.redisTemplate = redisTemplate;
this.setPostOnly(false);
this.setRequiresAuthenticationRequestMatcher(new AntPathRequestMatcher("/admin/acl/login","POST"));
}
@Override
public Authentication attemptAuthentication(HttpServletRequest req, HttpServletResponse res)
throws AuthenticationException {
try {
User user = new ObjectMapper().readValue(req.getInputStream(), User.class);
return authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword(), new ArrayList()));
} catch (IOException e) {
throw new RuntimeException(e);
}
}
/**
* 登录成功
* @param req
* @param res
* @param chain
* @param auth
* @throws IOException
* @throws ServletException
*/
@Override
protected void successfulAuthentication(HttpServletRequest req, HttpServletResponse res, FilterChain chain,
Authentication auth) throws IOException, ServletException {
SecurityUser user = (SecurityUser) auth.getPrincipal();
String token = tokenManager.createToken(user.getCurrentUserInfo().getUsername());
redisTemplate.opsForValue().set(user.getCurrentUserInfo().getUsername(), user.getPermissionValueList());
ResponseUtil.out(res, R.ok().data("token", token));
}
/**
* 登录失败
* @param request
* @param response
* @param e
* @throws IOException
* @throws ServletException
*/
@Override
protected void unsuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response,
AuthenticationException e) throws IOException, ServletException {
ResponseUtil.out(response, R.error());
}
}
（2）TokenAuthenticationFilter：
授权filter
import com.royal.commonutils.R;
import com.royal.commonutils.utils.ResponseUtil;
import com.royal.serurity.security.TokenManager;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.GrantedAuthority;

*/
public class TokenAuthenticationFilter extends BasicAuthenticationFilter {
private TokenManager tokenManager;
private RedisTemplate redisTemplate;
public TokenAuthenticationFilter(AuthenticationManager authManager, TokenManager tokenManager,RedisTemplate redisTemplate) {
super(authManager);
this.tokenManager = tokenManager;
this.redisTemplate = redisTemplate;
}
@Override
protected void doFilterInternal(HttpServletRequest req, HttpServletResponse res, FilterChain chain)
throws IOException, ServletException {
logger.info("================="+req.getRequestURI());
if(req.getRequestURI().indexOf("admin") == -1) {
chain.doFilter(req, res);
return;
}
UsernamePasswordAuthenticationToken authentication = null;
try {
authentication = getAuthentication(req);
} catch (Exception e) {
ResponseUtil.out(res, R.error());
}
if (authentication != null) {
SecurityContextHolder.getContext().setAuthentication(authentication);
} else {
ResponseUtil.out(res, R.error());
}
chain.doFilter(req, res);
}
private UsernamePasswordAuthenticationToken getAuthentication(HttpServletRequest request) {
// token置于header里
String token = request.getHeader("token");
if (token != null && !"".equals(token.trim())) {
String userName = tokenManager.getUserFromToken(token);
List permissionValueList = (List) redisTemplate.opsForValue().get(userName);
Collection authorities = new ArrayList();
for(String permissionValue : permissionValueList) {
if(StringUtils.isEmpty(permissionValue)) continue;
SimpleGrantedAuthority authority = new SimpleGrantedAuthority(permissionValue);
authorities.add(authority);
}
if (!StringUtils.isEmpty(userName)) {
return new UsernamePasswordAuthenticationToken(userName, token, authorities);
}
return null;
}
return null;
}
}
附：ResponseUtil工具
