SpringSecurity介绍
SpringSecurity是一个用于Java 企业级应用程序的安全框架,主要包含用户认证和用户授权两个方面,相比较Shiro而言,Security功能更加的强大,它可以很容易地扩展以满足更多安全控制方面的需求,但也相对它的学习成本会更高,两种框架各有利弊。实际开发中还是要根据业务和项目的需求来决定使用哪一种.
JWT的认证传输协议
JWT是在Web应用中安全传递信息的规范,从本质上来说是Token的演变,是一种生成加密用户身份信息的Token,特别适用于分布式单点登陆的场景,无需在服务端保存用户的认证信息,而是直接对Token进行校验获取用户信息,使单点登录更为简单灵活。

开发核心类
编写JWT工具类
@Slf4j
public class JWTTokenUtil
/**
* 生成Token
* @Param selfUserEntity 用户安全实体
* @Return Token
*/
public static String createAccessToken(SelfUserEntity selfUserEntity)
// 登陆成功生成JWT
String token = Jwts.builder()
// 放入用户名和用户ID
.setId(selfUserEntity.getUserId()+"")
// 主题
.setSubject(selfUserEntity.getUsername())
// 签发时间
.setIssuedAt(new Date())
// 签发者
.setIssuer("sans")
// 自定义属性 放入用户拥有权限
.claim("authorities", JSON.toJSONString(selfUserEntity.getAuthorities()))
// 失效时间
.setExpiration(new Date(System.currentTimeMillis() + JWTConfig.expiration))
// 签名算法和密钥
.signWith(SignatureAlgorithm.HS512, JWTConfig.secret)
.compact();
return token;
无权限处理类
@Component
public class UserAuthAccessDeniedHandler implements AccessDeniedHandler
/**
* 暂无权限返回结果
*/
@Override
public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException exception)
ResultUtil.responseJson(response,ResultUtil.resultCode(403,"未授权"));
用户未登录处理类
/**
* 用户未登录处理类
*/
@Component
public class UserAuthenticationEntryPointHandler implements AuthenticationEntryPoint
@Override
public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception)
ResultUtil.responseJson(response,ResultUtil.resultCode(401,"未登录"));
登录失败处理类
@Slf4j
@Component
public class UserLoginFailureHandler implements AuthenticationFailureHandler
/**
* 登录失败返回结果
* @Author Sans
* @CreateTime 2019/10/3 9:12
*/
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception)
// 这些对于操作的处理类可以根据不同异常进行不同处理
if (exception instanceof UsernameNotFoundException)
log.info("【登录失败】"+exception.getMessage());
ResultUtil.responseJson(response,ResultUtil.resultCode(500,"用户名不存在"));
if (exception instanceof LockedException)
log.info("【登录失败】"+exception.getMessage());
ResultUtil.responseJson(response,ResultUtil.resultCode(500,"用户被冻结"));
if (exception instanceof BadCredentialsException)
log.info("【登录失败】"+exception.getMessage());
ResultUtil.responseJson(response,ResultUtil.resultCode(500,"用户名password不正确"));
ResultUtil.responseJson(response,ResultUtil.resultCode(500,"登录失败"));
登录成功处理类
@Slf4j
@Component
public class UserLoginSuccessHandler implements AuthenticationSuccessHandler
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication)
// 组装JWT
SelfUserEntity selfUserEntity = (SelfUserEntity) authentication.getPrincipal();
String token = JWTTokenUtil.createAccessToken(selfUserEntity);
token = JWTConfig.tokenPrefix + token;
// 封装返回参数
Map<String,Object> resultData = new HashMap<>();
resultData.put("code","200");
resultData.put("msg", "登录成功");
resultData.put("token",token);
ResultUtil.responseJson(response,resultData);
登出成功处理类
@Component
public class UserLogoutSuccessHandler implements LogoutSuccessHandler
@Override
public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication)
Map<String,Object> resultData = new HashMap<>();
resultData.put("code","200");
resultData.put("msg", "登出成功");
SecurityContextHolder.clearContext();
ResultUtil.responseJson(response,ResultUtil.resultSuccess(resultData));
编写Security核心类
自定义登录验证
@Component
public class UserAuthenticationProvider implements AuthenticationProvider
@Autowired
private SelfUserDetailsService selfUserDetailsService;
@Autowired
private SysUserService sysUserService;
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException
// 获取表单输入中返回的用户名
String userName = (String) authentication.getPrincipal();
// 获取表单中输入的password
String password = (String) authentication.getCredentials();
// 查询用户是否存在
SelfUserEntity userInfo = selfUserDetailsService.loadUserByUsername(userName);
if (userInfo == null)
throw new UsernameNotFoundException("用户名不存在");
// 还要判断password是否正确,这里我们的password使用BCryptPasswordEncoder进行加密的
if (!new BCryptPasswordEncoder().matches(password, userInfo.getPassword()))
throw new BadCredentialsException("password不正确");
// 还可以加一些其他信息的判断,比如用户账号已停用等判断
if (userInfo.getStatus().equals("PROHIBIT"))
throw new LockedException("该用户已被冻结");
// 角色集合
Set<GrantedAuthority> authorities = new HashSet<>();
// 查询用户角色
List<SysRoleEntity> sysRoleEntityList = sysUserService.selectSysRoleByUserId(userInfo.getUserId());
for (SysRoleEntity sysRoleEntity: sysRoleEntityList)
authorities.add(new SimpleGrantedAuthority("ROLE_" + sysRoleEntity.getRoleName()));
userInfo.setAuthorities(authorities);
// 进行登录
return new UsernamePasswordAuthenticationToken(userInfo, password, authorities);
@Override
public boolean supports(Class<?> authentication)
return true;
自定义PermissionEvaluator注解验证
自定义权限注解验证
@Component
public class UserPermissionEvaluator implements PermissionEvaluator
@Autowired
private SysUserService sysUserService;
/**
* hasPermission鉴权方法
* 这里仅仅判断PreAuthorize注解中的权限表达式
* 实际中可以根据业务需求设计数据库通过targetUrl和permission做更复杂鉴权
* @Param authentication 用户身份
* @Param targetUrl 请求路径
* @Param permission 请求路径权限
* @Return boolean 是否通过
*/
@Override
public boolean hasPermission(Authentication authentication, Object targetUrl, Object permission)
// 获取用户信息
SelfUserEntity selfUserEntity =(SelfUserEntity) authentication.getPrincipal();
// 查询用户权限(这里可以将权限放入缓存中提升效率)
Set<String> permissions = new HashSet<>();
List<SysMenuEntity> sysMenuEntityList = sysUserService.selectSysMenuByUserId(selfUserEntity.getUserId());
for (SysMenuEntity sysMenuEntity:sysMenuEntityList)
permissions.add(sysMenuEntity.getPermission());
// 权限对比
if (permissions.contains(permission.toString()))
return true;
return false;
@Override
public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission)
return false;
SpringSecurity核心配置类
/**

return handler;

// 添加JWT过滤器
http.addFilter(new JWTAuthenticationTokenFilter(authenticationManager()));
编写JWT拦截类
编写JWT接口请求校验拦截器
/**
* JWT接口请求校验拦截器
* 请求接口时会进入这里验证Token是否合法和过期
*/
@Slf4j
public class JWTAuthenticationTokenFilter extends BasicAuthenticationFilter
public JWTAuthenticationTokenFilter(AuthenticationManager authenticationManager)
super(authenticationManager);
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException
// 获得TokenHeader
String tokenHeader = request.getHeader(JWTConfig.tokenHeader);
if (null!=tokenHeader && tokenHeader.startsWith(JWTConfig.tokenPrefix))
try
// 获取请求头中JWT的Token
if (!StringUtils.isEmpty(request.getHeader(JWTConfig.tokenHeader)))
// 截取JWT前缀
String token = request.getHeader(JWTConfig.tokenHeader).replace(JWTConfig.tokenPrefix, "");
// 解析JWT
Claims claims = Jwts.parser()
.setSigningKey(JWTConfig.secret)
.parseClaimsJws(token)
.getBody();
// 获取用户名
String username = claims.getSubject();
String userId=claims.getId();
if(!StringUtils.isEmpty(username)&&!StringUtils.isEmpty(userId))
// 获取角色
List<GrantedAuthority> authorities = new ArrayList<>();
String authority = claims.get("authorities").toString();
if(!StringUtils.isEmpty(authority))
List<Map<String,String>> authorityMap = JSONObject.parseObject(authority, List.class);
for(Map<String,String> role : authorityMap)
if(!StringUtils.isEmpty(role))
authorities.add(new SimpleGrantedAuthority(role.get("authority")));
//组装参数
SelfUserEntity selfUserEntity = new SelfUserEntity();
selfUserEntity.setUsername(claims.getSubject());
selfUserEntity.setUserId(Long.parseLong(claims.getId()));
selfUserEntity.setAuthorities(authorities);
UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(selfUserEntity, userId, authorities);
SecurityContextHolder.getContext().setAuthentication(authentication);
catch (ExpiredJwtException e)
log.info("Token过期");
catch (Exception e)
log.info("Token无效");
filterChain.doFilter(request, response);
return;
权限注解和hasPermission权限扩展
Security允许我们在定义URL方法访问所应有的注解权限时使用SpringEL表达式,在定义所需的访问权限时如果对应的表达式返回结果为true,则表示拥有对应的权限,反之则没有权限,会进入到我们配置的UserAuthAccessDeniedHandler(暂无权限处理类)中进行处理.这里举一些例子,代码中注释有对应的描述.
/**
* 管理端信息
* @Return Map<String,Object> 返回数据MAP
*/
@PreAuthorize("hasRole(ADMIN)")
@RequestMapping(value = "/info",method = RequestMethod.GET)
public Map<String,Object> userLogin()
Map<String,Object> result = new HashMap<>();
SelfUserEntity userDetails = SecurityUtil.getUserInfo();
result.put("title","管理端信息");
result.put("data",userDetails);
return ResultUtil.resultSuccess(result);
/**
* 拥有ADMIN或者USER角色可以访问
* @Return Map<String,Object> 返回数据MAP
*/
@PreAuthorize("hasAnyRole(ADMIN,USER)")
@RequestMapping(value = "/list",method = RequestMethod.GET)
public Map<String,Object> list()
Map<String,Object> result = new HashMap<>();
List<SysUserEntity> sysUserEntityList = sysUserService.list();
result.put("title","拥有用户或者管理员角色都可以查看");
result.put("data",sysUserEntityList);
return ResultUtil.resultSuccess(result);
/**
* 拥有ADMIN和USER角色可以访问
* @Return Map<String,Object> 返回数据MAP
*/
@PreAuthorize("hasRole(ADMIN) and hasRole(USER)")
@RequestMapping(value = "/menuList",method = RequestMethod.GET)
public Map<String,Object> menuList()
Map<String,Object> result = new HashMap<>();
List<SysMenuEntity> sysMenuEntityList = sysMenuService.list();
result.put("title","拥有用户和管理员角色都可以查看");
result.put("data",sysMenuEntityList);
return ResultUtil.resultSuccess(result);
通常情况下使用hasRole和hasAnyRole基本可以满足大部分鉴权需求,但是有时候面对更复杂的场景上述常规表示式无法完成权限认证,Security也为我们提供了解决方案。通过hasPermission()来扩展表达式,使用hasPermission(),首先要实现PermissionEvaluator接口
自定义权限注解验证
@Component
public class UserPermissionEvaluator implements PermissionEvaluator
@Autowired
private SysUserService sysUserService;
/**
* hasPermission鉴权方法
* 这里仅仅判断PreAuthorize注解中的权限表达式
* 实际中可以根据业务需求设计数据库通过targetUrl和permission做更复杂鉴权
* 当然targetUrl不一定是URL可以是数据Id还可以是管理员标识等,这里根据需求自行设计
* @Param authentication 用户身份(在使用hasPermission表达式时Authentication参数默认会自动带上)
* @Param targetUrl 请求路径
* @Param permission 请求路径权限
* @Return boolean 是否通过
*/
@Override
public boolean hasPermission(Authentication authentication, Object targetUrl, Object permission)
// 获取用户信息
SelfUserEntity selfUserEntity =(SelfUserEntity) authentication.getPrincipal();
// 查询用户权限(这里可以将权限放入缓存中提升效率)
Set<String> permissions = new HashSet<>();
List<SysMenuEntity> sysMenuEntityList = sysUserService.selectSysMenuByUserId(selfUserEntity.getUserId());
for (SysMenuEntity sysMenuEntity:sysMenuEntityList)
permissions.add(sysMenuEntity.getPermission());
// 权限对比
if (permissions.contains(permission.toString()))
return true;
return false;
@Override
public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission)
return false;
请求方法上添加hasPermission示例
/**
* 拥有sys:user:info权限可以访问
* hasPermission 第一个参数是请求路径 第二个参数是权限表达式
* @Return Map<String,Object> 返回数据MAP
*/
@PreAuthorize("hasPermission(/admin/userList,sys:user:info)")
@RequestMapping(value = "/userList",method = RequestMethod.GET)
public Map<String,Object> userList()
Map<String,Object> result = new HashMap<>();
List<SysUserEntity> sysUserEntityList = sysUserService.list();
result.put("title","拥有sys:user:info权限都可以查看");
result.put("data",sysUserEntityList);
return ResultUtil.resultSuccess(result);
hasPermission可以也可以和其他表达式联合使用
/**
* 拥有ADMIN角色和sys:role:info权限可以访问
* @Author Sans
* @CreateTime 2019/10/2 14:22
* @Return Map<String,Object> 返回数据MAP
*/
@PreAuthorize("hasRole(ADMIN) and hasPermission(/admin/adminRoleList,sys:role:info)")
@RequestMapping(value = "/adminRoleList",method = RequestMethod.GET)
public Map<String,Object> adminRoleList()
Map<String,Object> result = new HashMap<>();
List<SysRoleEntity> sysRoleEntityList = sysRoleService.list();
result.put("title","拥有ADMIN角色和sys:role:info权限可以访问");
result.put("data",sysRoleEntityList);
return ResultUtil.resultSuccess(result);
测试
注册用户操作
@Test
public void contextLoads()
// 注册用户
SysUserEntity sysUserEntity = new SysUserEntity();
sysUserEntity.setUsername("sans");
sysUserEntity.setPassword(bCryptPasswordEncoder.encode("123456"));
// 设置用户状态
sysUserEntity.setStatus("NORMAL");
sysUserService.save(sysUserEntity);
// 分配角色 1:ADMIN 2:USER
SysUserRoleEntity sysUserRoleEntity = new SysUserRoleEntity();
sysUserRoleEntity.setRoleId(2L);
sysUserRoleEntity.setUserId(sysUserEntity.getUserId());
sysUserRoleService.save(sysUserRoleEntity);
登录USER角色账号,登录成功后我们会获取到身份认证的Token。
登录用户操作
访问USER角色的接口,把上一步获取到的Token设置在Headers中,Key为Authorization,我们之前实现的JWTAuthenticationTokenFilter拦截器会根据请求头中的Authorization获取并解析Token。
查看用户操作
使用USER角色Token访问ADMIN角色的接口,会被拒绝,告知未授权(暂无权限会进入我们定义的UserAuthAccessDeniedHandler这个类进行处理)
查看用户操作
非主线篇
本文讲述一下如何自定义Spring Security的登录认证操作,目前大多数的项目都是基于前后端分离的,但是也有很多场景下也会存在后端模板技术,如何给出一个采用ajax的登录及返回的前后端分离方式并且兼容后端模板技术的功能代码。
AjaxAuthSuccessHandler
public class AjaxAuthSuccessHandler extends SimpleUrlAuthenticationSuccessHandler
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException
response.setStatus(HttpServletResponse.SC_OK);
AjaxAuthFailHandler
public class AjaxAuthFailHandler extends SimpleUrlAuthenticationFailureHandler
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Authentication failed");
ajax的异常处理
public class UnauthorizedEntryPoint implements AuthenticationEntryPoint
@Override
public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException
if(isAjaxRequest(request))
response.sendError(HttpServletResponse.SC_UNAUTHORIZED,authException.getMessage());
else
response.sendRedirect("/login.html");
public static boolean isAjaxRequest(HttpServletRequest request)
String ajaxFlag = request.getHeader("X-Requested-With");
return ajaxFlag != null && "XMLHttpRequest".equals(ajaxFlag);
这里我们自定义成功及失败的ajax返回,当然这里我们简单处理,只返回statusCode
security配置
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter
@Override
protected void configure(HttpSecurity http) throws Exception
http
.exceptionHandling().authenticationEntryPoint(new UnauthorizedEntryPoint())
.and()
.csrf().disable()
.authorizeRequests()
.antMatchers("/login","/css/**", "/js/**","/fonts/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login.html")
.loginProcessingUrl("/login")
.usernameParameter("name")
.passwordParameter("password")
.successHandler(new AjaxAuthSuccessHandler())
.failureHandler(new AjaxAuthFailHandler())
.permitAll()
.and()
.logout()
.logoutUrl("/logout")
.permitAll();
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception
auth
.inMemoryAuthentication()
.withUser("admin").password("admin").roles("USER");
这里有几个要注意的点:
-
permitAll:这里要添加前端资源路径,以及登陆表单请求的接口地址/login
-
loginPage:这里设置登录页面的地址,这里我们用静态页面,即static目录下的login.html
- ajax配置:将authenticationEntryPoint,successHandler,failureHandler设置为上面自定义的ajax处理类
