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：
- 用户登录时的验证；
- 用户登录后每次访问时的权限认证
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。
