pom.mx引入相关jar包
org.apache.shiro shiro-spring ${shiro.version} org.apache.shiro shiro-core ${shiro.version} io.jsonwebtoken jjwt 0.9.0
Shrio 的相关配置
划重点！！自定义了一个Filter
filterMap.put("JWTFilter", new JWTFilter());@Configuration
public 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 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 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
@RestControllerAdvice
public 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
*/
@RestController
public 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());
}
}springboot是什么
springboot一种全新的编程规范，其设计目的是用来简化新Spring应用的初始搭建以及开发过程，SpringBoot也是一个服务于框架的框架，服务范围是简化配置文件。
