本文介绍了Spring-boot结合Shrio实现JWT的方法，分享给大家，具体如下：
关于验证大致分为两个方面：
主要解决方法：使用自定义的Shiro Filter
项目搭建：
这是一个spring-boot 的web项目，不了解spring-boot的项目搭建，请google。
pom.mx引入相关jar包
<!-- shiro 权限管理 --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>${shiro.version}</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>${shiro.version}</version> </dependency> <!-- JWT --> <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt</artifactId> <version>0.9.0</version> </dependency>Shrio 的相关配置
划重点！！自定义了一个Filter
filterMap.put("JWTFilter", new JWTFilter());@Configurationpublic class ShiroConfig { @Bean public ShiroFilterFactoryBean getShiroFilterFactoryBean(SecurityManager securityManager) { ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean(); shiroFilterFactoryBean.setSecurityManager(securityManager); // 添加自己的过滤器并且取名为JWTFilter Map<String, Filter> filterMap = new HashMap<>(); filterMap.put("JWTFilter", new JWTFilter()); shiroFilterFactoryBean.setFilters(filterMap); /* * 自定义url规则 * http://shiro.apache.org/web.html#urls- */ Map<String, String> filterChainDefinitionMap = shiroFilterFactoryBean.getFilterChainDefinitionMap(); filterChainDefinitionMap.put("/**", "JWTFilter"); shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap); return shiroFilterFactoryBean; } /** * securityManager 不用直接注入shiroDBRealm，可能会导致事务失效 * 解决方法见 handleContextRefresh * http://www.debugrun.com/a/NKS9EJQ.html */ @Bean("securityManager") public DefaultWebSecurityManager securityManager(TokenRealm tokenRealm) { DefaultWebSecurityManager manager = new DefaultWebSecurityManager(); manager.setRealm(tokenRealm); /* * 关闭shiro自带的session，详情见文档 * http://shiro.apache.org/session-management.html#SessionManagement-StatelessApplications%28Sessionless%29 */ DefaultSubjectDAO subjectDAO = new DefaultSubjectDAO(); DefaultSessionStorageEvaluator defaultSessionStorageEvaluator = new DefaultSessionStorageEvaluator(); defaultSessionStorageEvaluator.setSessionStorageEnabled(false); subjectDAO.setSessionStorageEvaluator(defaultSessionStorageEvaluator); manager.setSubjectDAO(subjectDAO); return manager; } @Bean public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() { return new LifecycleBeanPostProcessor(); } @Bean(name = "TokenRealm") @DependsOn("lifecycleBeanPostProcessor") public TokenRealm tokenRealm() { return new TokenRealm(); } @Bean @DependsOn("lifecycleBeanPostProcessor") public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() { DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator(); // 强制使用cglib，防止重复代理和可能引起代理出错的问题 // https://zhuanlan.zhihu.com/p/29161098 defaultAdvisorAutoProxyCreator.setProxyTargetClass(true); return defaultAdvisorAutoProxyCreator; } @Bean public AuthorizationAttributeSourceAdvisor getAuthorizationAttributeSourceAdvisor(SecurityManager securityManager) { AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor(); authorizationAttributeSourceAdvisor.setSecurityManager(securityManager); return new AuthorizationAttributeSourceAdvisor(); }}自定义Shrio filter
执行顺序：preHandle -> doFilterInternal -> executeLogin -> onLoginSuccess
主要判断是不是登录请求的是 doFilterInternal
public class JWTFilter extends BasicHttpAuthenticationFilter { /** * 自定义执行登录的方法 */ @Override protected boolean executeLogin(ServletRequest request, ServletResponse response) throws IOException { HttpServletRequest httpServletRequest = (HttpServletRequest) request; UsernamePasswordToken usernamePasswordToken = JSON.parseObject(httpServletRequest.getInputStream(), UsernamePasswordToken.class); // 提交给realm进行登入，如果错误他会抛出异常并被捕获 Subject subject = this.getSubject(request, response); subject.login(usernamePasswordToken); return this.onLoginSuccess(usernamePasswordToken, subject, request, response); //错误抛出异常 } /** * 最先执行的方法 */ @Override protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception { return super.preHandle(request, response); } /** * 登录成功后登录的操作 * 加上jwt 的header */ @Override protected boolean onLoginSuccess(AuthenticationToken token, Subject subject, ServletRequest request, ServletResponse response) { HttpServletResponse httpServletResponse = (HttpServletResponse) response; String jwtToken = Jwts.builder() .setId(token.getPrincipal().toString()) .setExpiration(DateTime.now().plusMinutes(30).toDate()) .signWith(SignatureAlgorithm.HS256, JWTCost.signatureKey) .compact(); httpServletResponse.addHeader(AUTHORIZATION_HEADER, jwtToken); return true; } /** * 登录以及校验的主要流程 * 判断是否是登录，或者是登陆后普通的一次请求 */ @Override public void doFilterInternal(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest; HttpServletResponse httpServletResponse = (HttpServletResponse) servletResponse; String servletPath = httpServletRequest.getServletPath(); if (StringUtils.equals(servletPath, "/login")) { //执行登录 this.executeLogin(servletRequest, servletResponse); } else { String authenticationHeader = httpServletRequest.getHeader(AUTHORIZATION_HEADER); if (StringUtils.isNotEmpty(authenticationHeader)) { Claims body = Jwts.parser() .setSigningKey(JWTCost.signatureKey) .parseClaimsJws(authenticationHeader) .getBody(); if (body != null) { //更新token body.setExpiration(DateTime.now().plusMinutes(30).toDate()); String updateToken = Jwts.builder().setClaims(body).compact(); httpServletResponse.addHeader(AUTHORIZATION_HEADER, updateToken); //添加用户凭证 PrincipalCollection principals = new SimplePrincipalCollection(body.getId(), JWTCost.UserNamePasswordRealm);//拼装shiro用户信息 WebSubject.Builder builder = new WebSubject.Builder(servletRequest, servletResponse); builder.principals(principals); builder.authenticated(true); builder.sessionCreationEnabled(false); WebSubject subject = builder.buildWebSubject(); //塞入容器，统一调用 ThreadContext.bind(subject); filterChain.doFilter(httpServletRequest, httpServletResponse); } } else { httpServletResponse.setStatus(HttpStatus.FORBIDDEN.value()); } } }}登录失败处理
处理Shrio异常
@RestControllerAdvicepublic class GlobalControllerExceptionHandler { @ExceptionHandler(value = Exception.class) public Object allExceptionHandler(HttpServletRequest request, HttpServletResponse response, Exception exception) { String message = exception.getCause().getMessage(); LogUtil.error(message); return new ResultInfo(exception.getClass().getName(), message); } /*=========== Shiro 异常拦截==============*/ @ExceptionHandler(value = IncorrectCredentialsException.class) public String IncorrectCredentialsException(HttpServletRequest request, HttpServletResponse response, Exception exception) { response.setStatus(HttpStatus.FORBIDDEN.value()); return "IncorrectCredentialsException"; } @ExceptionHandler(value = UnknownAccountException.class) public String UnknownAccountException(HttpServletRequest request, HttpServletResponse response, Exception exception) { response.setStatus(HttpStatus.FORBIDDEN.value()); return "UnknownAccountException"; } @ExceptionHandler(value = LockedAccountException.class) public String LockedAccountException(HttpServletRequest request, HttpServletResponse response, Exception exception) { response.setStatus(HttpStatus.FORBIDDEN.value()); return "LockedAccountException"; } @ExceptionHandler(value = ExcessiveAttemptsException.class) public String ExcessiveAttemptsException(HttpServletRequest request, HttpServletResponse response, Exception exception) { response.setStatus(HttpStatus.FORBIDDEN.value()); return "ExcessiveAttemptsException"; } @ExceptionHandler(value = AuthenticationException.class) public String AuthenticationException(HttpServletRequest request, HttpServletResponse response, Exception exception) { response.setStatus(HttpStatus.FORBIDDEN.value()); return "AuthenticationException"; } @ExceptionHandler(value = UnauthorizedException.class) public String UnauthorizedException(HttpServletRequest request, HttpServletResponse response, Exception exception) { response.setStatus(HttpStatus.FORBIDDEN.value()); return "UnauthorizedException"; }}处理JWT异常
这是个坑，因为是在filter内发生的异常，@ExceptionHandler是截获不到的。
/** * 截获spring boot Error页面 */@RestControllerpublic class GlobalExceptionHandler implements ErrorController { @Override public String getErrorPath() { return "/error"; } @RequestMapping(value = "/error") public Object error(HttpServletRequest request, HttpServletResponse response) throws Exception { // 错误处理逻辑 Exception exception = (Exception) request.getAttribute("javax.servlet.error.exception"); Throwable cause = exception.getCause(); if (cause instanceof ExpiredJwtException) { response.setStatus(HttpStatus.GATEWAY_TIMEOUT.value()); return new ResultInfo("ExpiredJwtException", cause.getMessage()); } if (cause instanceof MalformedJwtException) { response.setStatus(HttpStatus.FORBIDDEN.value()); return new ResultInfo("MalformedJwtException", cause.getMessage()); } return new ResultInfo(cause.getCause().getMessage(), cause.getMessage()); }}关于权限等授权信息，可以直接放到Redis中实现缓存。我认为也是不错的。
源码奉上：githup-shiro分支 ：温馨提示：平时测试代码可能比较乱。
