SpringSecurity自定义成功失败处理器的示例代码
1.新建SpringBoot工程
2.项目依赖
org.springframework.boot spring-boot-starter-security org.springframework.boot spring-boot-starter-thymeleaf org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-tomcat provided org.projectlombok lombok org.springframework.boot spring-boot-starter-test
3.定义登录成功处理器
- 新建一个类实现AuthenticationSuccessHandler
- 重写onAuthenticationSuccess方法
packagezw.springboot.controller; importlombok.SneakyThrows; importorg.json.JSONObject; importorg.springframework.security.core.Authentication; importorg.springframework.security.web.authentication.AuthenticationSuccessHandler; importorg.springframework.stereotype.Component; importjavax.servlet.ServletException; importjavax.servlet.http.HttpServletRequest; importjavax.servlet.http.HttpServletResponse; importjava.io.IOException; importjava.io.PrintWriter; /** *@classNameLoginSuccessHandler *@description登录成功处理器 *@author周威 *@date2020-09-0313:50 **/ @Component publicclassLoginSuccessHandlerimplementsAuthenticationSuccessHandler { @SneakyThrows @Override publicvoidonAuthenticationSuccess(HttpServletRequestrequest,HttpServletResponseresponse,Authenticationauthentication)throwsIOException,ServletException { //设置response缓冲区字符集 response.setCharacterEncoding("UTF-8"); //定义一个JSONObject对象 JSONObjectobject=newJSONObject(); //填写登录成功响应信息 object.put("code",1); object.put("msg","登录成功"); //设置响应头 response.setContentType("application/json;charset=utf-8"); //获得打印输出流 PrintWriterpw=response.getWriter(); //向客户端写入一个字符串 pw.print(object.toString()); //关闭流资源 pw.close(); } }
4.定义登录失败处理器新建一个类实现AuthenticationFailureHandler接口重写onAuthenticationFailure方法
packagezw.springboot.controller; importlombok.SneakyThrows; importorg.json.JSONObject; importorg.springframework.security.core.AuthenticationException; importorg.springframework.security.web.authentication.AuthenticationFailureHandler; importorg.springframework.stereotype.Component; importjavax.servlet.ServletException; importjavax.servlet.http.HttpServletRequest; importjavax.servlet.http.HttpServletResponse; importjava.io.IOException; importjava.io.PrintWriter; /** *@classNameLoginErrorHandler *@description登录失败处理器 *@author周威 *@date2020-09-0313:57 **/ @Component publicclassLoginErrorHandlerimplementsAuthenticationFailureHandler { @SneakyThrows @Override publicvoidonAuthenticationFailure(HttpServletRequestrequest,HttpServletResponseresponse,AuthenticationExceptionauthenticationException)throwsIOException,ServletException { //设置response缓冲区字符集 response.setCharacterEncoding("UTF-8"); //定义一个JSONObject对象 JSONObjectobject=newJSONObject(); //填写登录失败响应信息 object.put("code",-1); object.put("msg","登录失败"); //设置响应头 response.setContentType("application/json;charset=utf-8"); //获得打印输出流 PrintWriterpw=response.getWriter(); //向客户端写入一个字符串 pw.print(object.toString()); //关闭流资源 pw.close(); } }
5.安全认证配置类
packagezw.springboot.config; importorg.springframework.beans.factory.annotation.Autowired; importorg.springframework.context.annotation.Bean; importorg.springframework.security.config.annotation.web.builders.HttpSecurity; importorg.springframework.security.config.annotation.web.configuration.EnableWebSecurity; importorg.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; importorg.springframework.security.core.userdetails.User; importorg.springframework.security.core.userdetails.UserDetailsService; importorg.springframework.security.crypto.bcrypt.BCryptPasswordEncoder; importorg.springframework.security.crypto.password.PasswordEncoder; importorg.springframework.security.provisioning.InMemoryUserDetailsManager; importorg.springframework.security.web.authentication.AuthenticationFailureHandler; importorg.springframework.security.web.authentication.AuthenticationSuccessHandler; /** *@classNameSpringSecurityConfig *@description安全人认证配置类 *@author周威 *@date2020-09-0313:42 **/ @EnableWebSecurity publicclassSpringSecurityConfigextendsWebSecurityConfigurerAdapter { @Autowired privateAuthenticationSuccessHandlerloginSuccessHandler; @Autowired privateAuthenticationFailureHandlerloginErrorHandler; //定义用户信息服务 @Bean @Override protectedUserDetailsServiceuserDetailsService() { InMemoryUserDetailsManagermanager=newInMemoryUserDetailsManager(); //模拟两个用户身份 manager.createUser(User.withUsername("admin").password(passwordEncoder().encode("123456")).authorities("p1").build()); manager.createUser(User.withUsername("user").password(passwordEncoder().encode("654321")).authorities("p2").build()); returnmanager; } //定义密码加密器 @Bean publicPasswordEncoderpasswordEncoder() { returnnewBCryptPasswordEncoder(); } //定义拦截机制 @Override protectedvoidconfigure(HttpSecurityhttp)throwsException { http .authorizeRequests() //设置哪些请求需要认证 .antMatchers("/**").authenticated() .and() //启用表单登录认证 .formLogin() //指定登录成功处理器 .successHandler(loginSuccessHandler) //指定登录失败处理器 .failureHandler(loginErrorHandler); } }
6.项目运行测试
7.登录成功测试
8.登录失败测试
