基本配置和配置自定义过滤器

package com.study.auth.config.core; import com.study.auth.config.core.authentication.AccountAuthenticationProvider;import com.study.auth.config.core.authentication.MailAuthenticationProvider;import com.study.auth.config.core.authentication.PhoneAuthenticationProvider;import com.study.auth.config.core.filter.CustomerUsernamePasswordAuthenticationFilter;import com.study.auth.config.core.handler.CustomerAuthenticationFailureHandler;import com.study.auth.config.core.handler.CustomerAuthenticationSuccessHandler;import com.study.auth.config.core.handler.CustomerLogoutSuccessHandler;import com.study.auth.config.core.observer.CustomerUserDetailsService;import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Bean;import org.springframework.security.authentication.AuthenticationManager;import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;import org.springframework.security.config.annotation.web.builders.HttpSecurity;import org.springframework.security.config.annotation.web.builders.WebSecurity;import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;import org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter;import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter; /** * @Package: com.study.auth.config * @Description: <> * @Author: milla * @CreateDate: 2020/09/04 11:27 * @UpdateUser: milla * @UpdateDate: 2020/09/04 11:27 * @UpdateRemark: <> * @Version: 1.0 */@Slf4j@EnableWebSecuritypublic class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private AccountAuthenticationProvider provider; @Autowired private MailAuthenticationProvider mailProvider; @Autowired private PhoneAuthenticationProvider phoneProvider; @Autowired private CustomerUserDetailsService userDetailsService; @Autowired private CustomerAuthenticationSuccessHandler successHandler; @Autowired private CustomerAuthenticationFailureHandler failureHandler; @Autowired private CustomerLogoutSuccessHandler logoutSuccessHandler; /** * 配置拦截器保护请求 * * @param http * @throws Exception */ @Override protected void configure(HttpSecurity http) throws Exception { //配置HTTP基本身份验证//使用自定义过滤器-兼容json和表单登录 http.addFilterBefore(customAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class).httpBasic().and().authorizeRequests()//表示访问 /setting 这个接口，需要具备 admin 这个角色.antMatchers('/setting').hasRole('admin')//表示剩余的其他接口，登录之后就能访问.anyRequest().authenticated().and().formLogin()//定义登录页面，未登录时，访问一个需要登录之后才能访问的接口，会自动跳转到该页面.loginPage('/noToken')//登录处理接口-登录时候访问的接口地址.loginProcessingUrl('/account/login')//定义登录时,表单中用户名的 key，默认为 username.usernameParameter('username')//定义登录时,表单中用户密码的 key，默认为 password.passwordParameter('password')////登录成功的处理器//.successHandler(successHandler)////登录失败的处理器//.failureHandler(failureHandler)//允许所有用户访问.permitAll().and().logout().logoutUrl('/logout')//登出成功的处理.logoutSuccessHandler(logoutSuccessHandler).permitAll(); //关闭csrf跨域攻击防御 http.csrf().disable(); } /** * 配置权限认证服务 * * @param auth * @throws Exception */ @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { //权限校验-只要有一个认证通过即认为是通过的(有一个认证通过就跳出认证循环)-适用于多登录方式的系统// auth.authenticationProvider(provider);// auth.authenticationProvider(mailProvider);// auth.authenticationProvider(phoneProvider); //直接使用userDetailsService auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder()); } /** * 配置Spring Security的Filter链 * * @param web * @throws Exception */ @Override public void configure(WebSecurity web) throws Exception { //忽略拦截的接口 web.ignoring().antMatchers('/noToken'); } /** * 指定验证manager * * @return * @throws Exception */ @Override @Bean public AuthenticationManager authenticationManagerBean() throws Exception { return super.authenticationManagerBean(); } /** * 注册自定义的UsernamePasswordAuthenticationFilter * * @return * @throws Exception */ @Bean public AbstractAuthenticationProcessingFilter customAuthenticationFilter() throws Exception { AbstractAuthenticationProcessingFilter filter = new CustomerUsernamePasswordAuthenticationFilter(); filter.setAuthenticationSuccessHandler(successHandler); filter.setAuthenticationFailureHandler(failureHandler); //过滤器拦截的url要和登录的url一致，否则不生效 filter.setFilterProcessesUrl('/account/login'); //这句很关键，重用WebSecurityConfigurerAdapter配置的AuthenticationManager，不然要自己组装AuthenticationManager filter.setAuthenticationManager(authenticationManagerBean()); return filter; }}自定义过滤器

根据ContentType是否为json进行判断，如果是就从body中读取参数，进行解析，并生成权限实体，进行权限认证

否则直接使用UsernamePasswordAuthenticationFilter中的方法

package com.study.auth.config.core.filter; import com.fasterxml.jackson.databind.ObjectMapper;import com.study.auth.config.core.util.AuthenticationStoreUtil;import com.study.auth.entity.bo.LoginBO;import lombok.extern.slf4j.Slf4j;import org.springframework.http.MediaType;import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;import org.springframework.security.core.Authentication;import org.springframework.security.core.AuthenticationException;import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter; import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.io.IOException;import java.io.InputStream; /** * @Package: com.study.auth.config.core.filter * @Description: <> * @Author: milla * @CreateDate: 2020/09/11 16:04 * @UpdateUser: milla * @UpdateDate: 2020/09/11 16:04 * @UpdateRemark: <> * @Version: 1.0 */@Slf4jpublic class CustomerUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter { /** * 空字符串 */ private final String EMPTY = ''; @Override public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException { //如果不是json使用自带的过滤器获取参数 if (!request.getContentType().equals(MediaType.APPLICATION_JSON_UTF8_VALUE) && !request.getContentType().equals(MediaType.APPLICATION_JSON_VALUE)) { String username = this.obtainUsername(request); String password = this.obtainPassword(request); storeAuthentication(username, password); Authentication authentication = super.attemptAuthentication(request, response); return authentication; } //如果是json请求使用取参数逻辑 ObjectMapper mapper = new ObjectMapper(); UsernamePasswordAuthenticationToken authRequest = null; try (InputStream is = request.getInputStream()) { LoginBO account = mapper.readValue(is, LoginBO.class); storeAuthentication(account.getUsername(), account.getPassword()); authRequest = new UsernamePasswordAuthenticationToken(account.getUsername(), account.getPassword()); } catch (IOException e) { log.error('验证失败：{}', e); authRequest = new UsernamePasswordAuthenticationToken(EMPTY, EMPTY); } finally { setDetails(request, authRequest); Authentication authenticate = this.getAuthenticationManager().authenticate(authRequest); return authenticate; } } /** * 保存用户名和密码 * * @param username 帐号/邮箱/手机号 * @param password 密码/验证码 */ private void storeAuthentication(String username, String password) { AuthenticationStoreUtil.setUsername(username); AuthenticationStoreUtil.setPassword(password); }}

其中会有body中的传参问题，所以使用ThreadLocal传递参数

PS：枚举类具备线程安全性

package com.study.auth.config.core.util; /** * @Package: com.study.auth.config.core.util * @Description: <使用枚举可以保证线程安全> * @Author: milla * @CreateDate: 2020/09/11 17:48 * @UpdateUser: milla * @UpdateDate: 2020/09/11 17:48 * @UpdateRemark: <> * @Version: 1.0 */public enum AuthenticationStoreUtil { AUTHENTICATION; /** * 登录认证之后的token */ private final ThreadLocal<String> tokenStore = new ThreadLocal<>(); /** * 需要验证用户名 */ private final ThreadLocal<String> usernameStore = new ThreadLocal<>(); /** * 需要验证的密码 */ private final ThreadLocal<String> passwordStore = new ThreadLocal<>(); public static String getUsername() { return AUTHENTICATION.usernameStore.get(); } public static void setUsername(String username) { AUTHENTICATION.usernameStore.set(username); } public static String getPassword() { return AUTHENTICATION.passwordStore.get(); } public static void setPassword(String password) { AUTHENTICATION.passwordStore.set(password); } public static String getToken() { return AUTHENTICATION.tokenStore.get(); } public static void setToken(String token) { AUTHENTICATION.tokenStore.set(token); } public static void clear() { AUTHENTICATION.tokenStore.remove(); AUTHENTICATION.passwordStore.remove(); AUTHENTICATION.usernameStore.remove(); }}实现UserDetailsService接口

至此，就可以传递Json参数了
