springboot2.0整合springsecurity前后端分离进行自定义权限控制
在阅读本文之前可以先看看springsecurity的基本执行流程，下面我展示一些核心配置文件，后面给出完整的整合代码到git上面，有兴趣的小伙伴可以下载进行研究
使用maven工程构建项目，首先需要引入最核心的依赖，
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
由于这里我们整合的项目进行了前后端分离，所以我们首先需要自定义登录成功和失败，登出成功的自定义处理类
其实就是实现不同的handler即可：1.首先我们来看登录成功的处理类
/**
* 处理登录验证成功的类
* @author zhoukebo
* @date 2018/9/4
*/
@Component
public class FuryAuthSuccessHandler implements AuthenticationSuccessHandler {
/**Json转化工具*/
@Autowired
private ObjectMapper objectMapper;
@Override
public void onAuthenticationSuccess(HttpServletRequest request,HttpServletResponse response, Authentication authentication) throws IOException{
SysUser userDetails = (SysUser)authentication.getPrincipal();
System.out.println("管理员 " + userDetails.getUsername() + " 登录");
Map<String,String> map=new HashMap<>(2);
map.put("code", "200");
map.put("msg", "登录成功");
response.setContentType("application/json;charset=UTF-8");
response.getWriter().write(objectMapper.writeValueAsString(map));
}
}
2.登录验证失败的类
/**
* 处理登录验证失败的类
* @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("登录验证失败");
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.自定义处理注销成功的类
/**
* 处理注销成功
* @author zhoukebo
* @date 2018/9/4
*/
@Component
public class MyLogoutSuccessHandler implements LogoutSuccessHandler {
/**Json转化工具*/
@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.自定义没有权限的处理类
/**
* 处理没有权限的类
* @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));
}
}
然后对springsecurity进行详细的配置需要继承WebSecurityConfigurerAdapter类，下面是配置文件的详情
/**
* spring Security配置安全控制中心
*
* @author zhoukb
*/
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
/**
* 依赖注入自定义的登录成功处理器
*/
@Autowired
private FuryAuthSuccessHandler furyAuthSuccessHandler;
/**
* 依赖注入自定义的登录失败处理器
*/
@Autowired
private FuryAuthFailureHandler furyAuthFailureHandler;
/**
* 依赖注入自定义的注销成功的处理器
*/
@Autowired
private MyLogoutSuccessHandler myLogoutSuccessHandler;
/**
* 注册没有权限的处理器
*/
@Autowired
private RestAuthAccessDeniedHandler restAuthAccessDeniedHandler;
/***注入自定义的CustomPermissionEvaluator*/
@Bean
public DefaultWebSecurityExpressionHandler webSecurityExpressionHandler() {
DefaultWebSecurityExpressionHandler handler = new DefaultWebSecurityExpressionHandler();
handler.setPermissionEvaluator(new CustomPermissionEvaluator());
return handler;
}
/***注入我们自己的登录逻辑验证器AuthenticationProvider*/
@Autowired
private AuthenticationProvider authenticationProvider;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
//这里可启用我们自己的登陆验证逻辑
auth.authenticationProvider(authenticationProvider);
}
/**
* 配置spring security的控制逻辑
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
//"/login"不进行权限验证
.antMatchers("/login").permitAll()
.antMatchers("/favicon.ico").permitAll()
.anyRequest().authenticated() //其他的需要登陆后才能访问
.and()
.formLogin()
//loginProcessingUrl用于指定前后端分离的时候调用后台登录接口的名称
.loginProcessingUrl("/login")
//配置登录成功的自定义处理类
.successHandler(furyAuthSuccessHandler)
//配置登录失败的自定义处理类
.failureHandler(furyAuthFailureHandler)
.and()
//loginProcessingUrl用于指定前后端分离的时候调用后台注销接口的名称
.logout().logoutUrl("/logout")
.logoutSuccessHandler(myLogoutSuccessHandler)
.and()
//配置没有权限的自定义处理类
.exceptionHandling().accessDeniedHandler(restAuthAccessDeniedHandler)
.and()
.cors()//新加入
.and()
.csrf().disable();// 取消跨站请求伪造防护
}
}
上面我们配置了自定义的登录逻辑的验证MyAuthenticationProvider，和自定义的权限验证CustomPermissionEvaluator代码如下
/**
* 实现自己的AuthenticationProvider类，用来自定义用户校验机制
* @author zhoukebo
* @date 2018/9/5
*/
@Component
public class MyAuthenticationProvider implements AuthenticationProvider {
@Autowired
private CustomerDetailService customerDetailService;
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
// 获取表单输入中返回的用户名;
String userName = (String) authentication.getPrincipal();
// 获取表单中输入的密码；
String password = (String) authentication.getCredentials();
// 这里调用我们的自己写的获取用户的方法；
UserDetails userInfo = customerDetailService.loadUserByUsername(userName);
if (userInfo == null) {
throw new BadCredentialsException("用户名不存在");
}
// 这里我们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
if (!new BCryptPasswordEncoder().matches(password, userInfo.getPassword())) {
throw new BadCredentialsException("密码不正确");
}
// 这里还可以加一些其他信息的判断，比如用户账号已停用等判断。
Collection<? extends GrantedAuthority> authorities = userInfo.getAuthorities();
// 构建返回的用户登录成功的token
return new UsernamePasswordAuthenticationToken(userInfo, password, authorities);
}
@Override
public boolean supports(Class<?> authentication) {
// 这里直接改成retrun true;表示是支持这个执行
return true;
}
}
/**
* 我们需要自定义对hasPermission()方法的处理，
* 就需要自定义PermissionEvaluator，创建类CustomPermissionEvaluator，实现PermissionEvaluator接口。
* @author zhoukebo
* @date 2018/9/5
*/
@Component
public class CustomPermissionEvaluator implements PermissionEvaluator {
/**
* 自定义验证方法
* @param authentication 登录的时候存储的用户信息
* @param targetDomainObject @PreAuthorize("hasPermission('/hello/**','r')") 中hasPermission的第一个参数
* @param permission @PreAuthorize("hasPermission('/hello/**','r')") 中hasPermission的第二个参数
* @return
*/
@Override
public boolean hasPermission(Authentication authentication, Object targetDomainObject, Object permission) {
// 获得loadUserByUsername()方法的结果
SysUser user = (SysUser)authentication.getPrincipal();
// 获得loadUserByUsername()中注入的权限
Collection<? extends GrantedAuthority> authorities = user.getAuthorities();
// 遍历用户权限进行判定
for(GrantedAuthority authority : authorities) {
UrlGrantedAuthority urlGrantedAuthority = (UrlGrantedAuthority) authority;
String permissionUrl = urlGrantedAuthority.getPermissionUrl();
// 如果访问的Url和权限用户符合的话，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：上面的自定义权限要生效还需要在WebSecurityConfig上面加上注解@EnableGlobalMethodSecurity(prePostEnabled = true)
完成登录逻辑还需要我们实现UserDetailsService接口，以便系统能够根据用户名去获取用户的信息，里面还可加上自己的逻辑
/**
* 需要自定义UserDetailsService实现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("用户名不存在");
}
List<SysRole> roles = user.getRoles();
//将所有的角色对应的资源权限全部放入user对应的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中包含两种自定义权限验证，有兴趣的小伙伴可以自行在github上面下载下来研究，不懂得可以交流，代码有什么不妥的地方也望大家互相指教
