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。

// 还要判断密码是否正确，这里我们的密码使用BCryptPasswordEncoder进行加密的

编写JWT拦截类

*/
@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
创建账户这里用户加密使用了Security推荐的bCryptPasswordEncoder方法
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)
更换ADMIN角色进行登录并访问ADMIN接口
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
