在閱讀本文之前可以先看看springsecurity的基本執行流程,下面我展示一些核心配置文件,后面給出完整的整合代碼到git上面,有興趣的小伙伴可以下載進行研究
使用maven工程構建項目,首先需要引入最核心的依賴,
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency>
由於這里我們整合的項目進行了前后端分離,所以我們首先需要自定義登錄成功和失敗,登出成功的自定義處理類
其實就是實現不同的handler即可:1.首先我們來看登錄成功的處理類
/** * 處理登錄驗證成功的類 * @author zhoukebo * @date 2018/9/4 */ @Component public class FuryAuthSuccessHandler implements AuthenticationSuccessHandler { /**Json轉化工具*/ @Autowired private ObjectMapper objectMapper; @Override public void onAuthenticationSuccess(HttpServletRequest request,HttpServletResponse response, Authentication authentication) throws IOException{ SysUser userDetails = (SysUser)authentication.getPrincipal(); System.out.println("管理員 " + userDetails.getUsername() + " 登錄"); Map<String,String> map=new HashMap<>(2); map.put("code", "200"); map.put("msg", "登錄成功"); response.setContentType("application/json;charset=UTF-8"); response.getWriter().write(objectMapper.writeValueAsString(map)); } }
2.登錄驗證失敗的類
/** * 處理登錄驗證失敗的類 * @author zhoukebo * @date 2018/9/4 */ @Component public class FuryAuthFailureHandler implements AuthenticationFailureHandler { @Autowired private ObjectMapper objectMapper; @Override public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException { System.out.println("登錄驗證失敗"); Map<String,String> map=new HashMap<>(2); map.put("code", "10001"); map.put("msg", exception.getMessage()); response.setContentType("application/json;charset=UTF-8"); response.getWriter().write(objectMapper.writeValueAsString(map)); } }
3.自定義處理注銷成功的類
/** * 處理注銷成功 * @author zhoukebo * @date 2018/9/4 */ @Component public class MyLogoutSuccessHandler implements LogoutSuccessHandler { /**Json轉化工具*/ @Autowired private ObjectMapper objectMapper; @Override public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException{ Map<String,String> map=new HashMap<>(2); map.put("code", "200"); map.put("msg", "登出成功"); response.setContentType("application/json;charset=UTF-8"); response.getWriter().write(objectMapper.writeValueAsString(map)); } }
4.自定義沒有權限的處理類
/** * 處理沒有權限的類 * @author zhoukebo * @date 2018/9/5 */ @Component public class RestAuthAccessDeniedHandler implements AccessDeniedHandler { @Autowired private ObjectMapper objectMapper; @Override public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException e) throws IOException, ServletException { Map<String,String> map=new HashMap<>(2); map.put("code", "403"); map.put("msg", e.getMessage()); response.setContentType("application/json;charset=UTF-8"); response.getWriter().write(objectMapper.writeValueAsString(map)); } }
然后對springsecurity進行詳細的配置需要繼承WebSecurityConfigurerAdapter類,下面是配置文件的詳情
/** * spring Security配置安全控制中心 * * @author zhoukb */ @Configuration @EnableWebSecurity @EnableGlobalMethodSecurity(prePostEnabled = true) public class WebSecurityConfig extends WebSecurityConfigurerAdapter { /** * 依賴注入自定義的登錄成功處理器 */ @Autowired private FuryAuthSuccessHandler furyAuthSuccessHandler; /** * 依賴注入自定義的登錄失敗處理器 */ @Autowired private FuryAuthFailureHandler furyAuthFailureHandler; /** * 依賴注入自定義的注銷成功的處理器 */ @Autowired private MyLogoutSuccessHandler myLogoutSuccessHandler; /** * 注冊沒有權限的處理器 */ @Autowired private RestAuthAccessDeniedHandler restAuthAccessDeniedHandler; /***注入自定義的CustomPermissionEvaluator*/ @Bean public DefaultWebSecurityExpressionHandler webSecurityExpressionHandler() { DefaultWebSecurityExpressionHandler handler = new DefaultWebSecurityExpressionHandler(); handler.setPermissionEvaluator(new CustomPermissionEvaluator()); return handler; } /***注入我們自己的登錄邏輯驗證器AuthenticationProvider*/ @Autowired private AuthenticationProvider authenticationProvider; @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { //這里可啟用我們自己的登陸驗證邏輯 auth.authenticationProvider(authenticationProvider); } /** * 配置spring security的控制邏輯 */ @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() //"/login"不進行權限驗證 .antMatchers("/login").permitAll() .antMatchers("/favicon.ico").permitAll() .anyRequest().authenticated() //其他的需要登陸后才能訪問 .and() .formLogin() //loginProcessingUrl用於指定前后端分離的時候調用后台登錄接口的名稱 .loginProcessingUrl("/login") //配置登錄成功的自定義處理類 .successHandler(furyAuthSuccessHandler) //配置登錄失敗的自定義處理類 .failureHandler(furyAuthFailureHandler) .and() //loginProcessingUrl用於指定前后端分離的時候調用后台注銷接口的名稱 .logout().logoutUrl("/logout") .logoutSuccessHandler(myLogoutSuccessHandler) .and() //配置沒有權限的自定義處理類 .exceptionHandling().accessDeniedHandler(restAuthAccessDeniedHandler) .and() .cors()//新加入 .and() .csrf().disable();// 取消跨站請求偽造防護 } }
上面我們配置了自定義的登錄邏輯的驗證MyAuthenticationProvider,和自定義的權限驗證CustomPermissionEvaluator代碼如下
/** * 實現自己的AuthenticationProvider類,用來自定義用戶校驗機制 * @author zhoukebo * @date 2018/9/5 */ @Component public class MyAuthenticationProvider implements AuthenticationProvider { @Autowired private CustomerDetailService customerDetailService; @Override public Authentication authenticate(Authentication authentication) throws AuthenticationException { // 獲取表單輸入中返回的用戶名; String userName = (String) authentication.getPrincipal(); // 獲取表單中輸入的密碼; String password = (String) authentication.getCredentials(); // 這里調用我們的自己寫的獲取用戶的方法; UserDetails userInfo = customerDetailService.loadUserByUsername(userName); if (userInfo == null) { throw new BadCredentialsException("用戶名不存在"); } // 這里我們還要判斷密碼是否正確,這里我們的密碼使用BCryptPasswordEncoder進行加密的 if (!new BCryptPasswordEncoder().matches(password, userInfo.getPassword())) { throw new BadCredentialsException("密碼不正確"); } // 這里還可以加一些其他信息的判斷,比如用戶賬號已停用等判斷。 Collection<? extends GrantedAuthority> authorities = userInfo.getAuthorities(); // 構建返回的用戶登錄成功的token return new UsernamePasswordAuthenticationToken(userInfo, password, authorities); } @Override public boolean supports(Class<?> authentication) { // 這里直接改成retrun true;表示是支持這個執行 return true; } }
/** * 我們需要自定義對hasPermission()方法的處理, * 就需要自定義PermissionEvaluator,創建類CustomPermissionEvaluator,實現PermissionEvaluator接口。 * @author zhoukebo * @date 2018/9/5 */ @Component public class CustomPermissionEvaluator implements PermissionEvaluator { /** * 自定義驗證方法 * @param authentication 登錄的時候存儲的用戶信息 * @param targetDomainObject @PreAuthorize("hasPermission('/hello/**','r')") 中hasPermission的第一個參數 * @param permission @PreAuthorize("hasPermission('/hello/**','r')") 中hasPermission的第二個參數 * @return */ @Override public boolean hasPermission(Authentication authentication, Object targetDomainObject, Object permission) { // 獲得loadUserByUsername()方法的結果 SysUser user = (SysUser)authentication.getPrincipal(); // 獲得loadUserByUsername()中注入的權限 Collection<? extends GrantedAuthority> authorities = user.getAuthorities(); // 遍歷用戶權限進行判定 for(GrantedAuthority authority : authorities) { UrlGrantedAuthority urlGrantedAuthority = (UrlGrantedAuthority) authority; String permissionUrl = urlGrantedAuthority.getPermissionUrl(); // 如果訪問的Url和權限用戶符合的話,返回true if(targetDomainObject.equals(permissionUrl)) { return true; } } return false; } @Override public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission) { return false; } }
注意:上面的自定義權限要生效還需要在WebSecurityConfig上面加上注解@EnableGlobalMethodSecurity(prePostEnabled = true)
完成登錄邏輯還需要我們實現UserDetailsService接口,以便系統能夠根據用戶名去獲取用戶的信息,里面還可加上自己的邏輯
/**
* 需要自定義UserDetailsService實現spring security的UserDetailsService接口
* @author zhoukebo
* @date 2018/9/4
*/
@Service
public class CustomerDetailService implements UserDetailsService {
@Autowired
SysUserRepository userRepository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
SysUser user = userRepository.findByUsername(username);
if (user == null) {
throw new UsernameNotFoundException("用戶名不存在");
}
List<SysRole> roles = user.getRoles();
//將所有的角色對應的資源權限全部放入user對應的grantedAuthority集合中
for (SysRole role : roles) {
List<SysResource> resources = role.getResources();
List<GrantedAuthority> grantedAuthorities = new ArrayList<>();
for (SysResource resource : resources) {
if (resource != null && resource.getResourceName()!=null) {
GrantedAuthority grantedAuthority = new UrlGrantedAuthority(resource.getMethodPath(),resource.getResourceName());
grantedAuthorities.add(grantedAuthority);
}
}
user.setGrantedAuthority(grantedAuthorities);
}
System.out.println("s:" + username);
return user;
}
}
以上就完成了springboot和springsecurity的整合工作,demo中包含兩種自定義權限驗證,有興趣的小伙伴可以自行在github上面下載下來研究,不懂得可以交流,代碼有什么不妥的地方也望大家互相指教
