Spring Boot 整合 Spring Security(配置登录/登出)

Spring Boot 整合 Spring Security ,配置登录/登出,如:登录接口,登录成功或失败后的响应等。

1 创建工程

创建 Spring Boot 项目 spring-boot-springsecurity-login ,添加 Web/Spring Security 依赖,如下:

最终的依赖如下:

<dependencies>
    <dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-securityartifactId>
    dependency>
    <dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-webartifactId>
    dependency>

    <dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-testartifactId>
        <scope>testscope>
        <exclusions>
            <exclusion>
                <groupId>org.junit.vintagegroupId>
                <artifactId>junit-vintage-engineartifactId>
            exclusion>
        exclusions>
    dependency>
    <dependency>
        <groupId>org.springframework.securitygroupId>
        <artifactId>spring-security-testartifactId>
        <scope>testscope>
    dependency>
dependencies>

2 配置 Spring Security

新增 SecurityConfig 配置类,如下:

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Bean
    PasswordEncoder passwordEncoder() {
//        return NoOpPasswordEncoder.getInstance();// 密码不加密
        return new BCryptPasswordEncoder();// 密码加密
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        // 在内存中配置 2 个用户
        /*auth.inMemoryAuthentication()
                .withUser("admin").password("123456").roles("admin")
                .and()
                .withUser("user").password("123456").roles("user");// 密码不加密*/

        auth.inMemoryAuthentication()
                .withUser("admin").password("$2a$10$fB2UU8iJmXsjpdk6T6hGMup8uNcJnOGwo2.QGR.e3qjIsdPYaS4LO").roles("admin")
                .and()
                .withUser("user").password("$2a$10$3TQ2HO/Xz1bVHw5nlfYTBON2TDJsQ0FMDwAS81uh7D.i9ax5DR46q").roles("user");// 密码加密
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // 开启登录配置
        http.authorizeRequests()
                // 表示 admin 角色能访问
                .antMatchers("/admin/**").hasRole("admin")
                // 表示 admin 或 user 角色都能访问
                // .antMatchers("/user/**").hasAnyRole("admin", "user")
                // 表示 admin 或 user 角色都能访问
                .antMatchers("/user/**").access("hasAnyRole('admin','user')")
                // 表示剩余的其他接口,登录之后就能访问
                .anyRequest().authenticated()
                .and()
                .formLogin()
                // 表示登录页的地址,例如当你访问一个需要登录后才能访问的资源时,系统就会自动给你通过【重定向】跳转到这个页面上来
                .loginPage("/login")
                // 表示处理登录请求的接口地址,默认为 /login
                .loginProcessingUrl("/doLogin")
                // 定义登录时,用户名的 key,默认为 username
                .usernameParameter("uname")
                // 定义登录时,密码的 key,默认为 password
                .passwordParameter("passwd")
                // 登录成功的处理器
                .successHandler(new AuthenticationSuccessHandler() {
                    @Override
                    public void onAuthenticationSuccess(HttpServletRequest req, HttpServletResponse resp, Authentication authentication) throws IOException, ServletException {
                        resp.setContentType("application/json;charset=utf-8");
                        PrintWriter out = resp.getWriter();
                        Map<String, Object> map = new HashMap<>();
                        map.put("status", 200);
                        map.put("msg", authentication.getPrincipal());
                        out.write(new ObjectMapper().writeValueAsString(map));
                        out.flush();
                        out.close();
                    }
                })
                // 登录失败的处理器
                .failureHandler(new AuthenticationFailureHandler() {
                    @Override
                    public void onAuthenticationFailure(HttpServletRequest req, HttpServletResponse resp, AuthenticationException e) throws IOException, ServletException {
                        resp.setContentType("application/json;charset=utf-8");
                        PrintWriter out = resp.getWriter();

                        map.put("status", 401);
                        if (e instanceof LockedException) {
                            map.put("msg", "账户被锁定,登录失败!");
                        } else if (e instanceof BadCredentialsException) {
                            map.put("msg", "用户名或密码输入错误,登录失败!");
                        } else if (e instanceof DisabledException) {

                        } else if (e instanceof AccountExpiredException) {
                            map.put("msg", "账户过期,登录失败!");
                        } else if (e instanceof CredentialsExpiredException) {
                            map.put("msg", "密码过期,登录失败!");
                        } else {
                            map.put("msg", "登录失败!");
                        }
                        out.write(new ObjectMapper().writeValueAsString(map));
                        out.flush();
                        out.close();
                    }
                })
                // 和表单登录相关的接口统统都直接通过
                .permitAll()
                .and()
                .logout()
                .logoutUrl("/logout")
                // 登出成功的处理器
                .logoutSuccessHandler(new LogoutSuccessHandler() {
                    @Override
                    public void onLogoutSuccess(HttpServletRequest req, HttpServletResponse resp, Authentication authentication) throws IOException, ServletException {
                        resp.setContentType("application/json;charset=utf-8");
                        PrintWriter out = resp.getWriter();
                        Map<String, Object> map = new HashMap<>();
                        map.put("status", 200);
                        map.put("msg", "注销登录成功!");
                        out.write(new ObjectMapper().writeValueAsString(map));
                        out.flush();
                        out.close();
                    }
                })
                .permitAll()
                .and()
                .csrf().disable()
                .exceptionHandling()
                // 无访问权限的处理器
                .accessDeniedHandler(new AccessDeniedHandler() {
                    @Override
                    public void handle(HttpServletRequest req, HttpServletResponse resp, AccessDeniedException e) throws IOException, ServletException {
                        resp.setContentType("application/json;charset=utf-8");
                        PrintWriter out = resp.getWriter();
                        Map<String, Object> map = new HashMap<>();
                        map.put("status", 403);
                        map.put("msg", "无访问权限!");
                        out.write(new ObjectMapper().writeValueAsString(map));
                        out.flush();
                        out.close();
                    }
                })
                // 默认情况下用户直接访问一个需要认证之后才可以访问的请求时,会被重定向到.loginPage("/login"),前后端分离时会导致跨域。
                // 增加如下配置后,就不会发生重定向操作了,服务端会直接给浏览器一个 JSON 提示
                .authenticationEntryPoint(new AuthenticationEntryPoint() {
                    @Override
                    public void commence(HttpServletRequest req, HttpServletResponse resp, AuthenticationException authException) throws IOException, ServletException {
                        resp.setContentType("application/json;charset=utf-8");
                        PrintWriter out = resp.getWriter();
                        Map<String, Object> map = new HashMap<>();
                        map.put("status", 401);
                        if (authException instanceof InsufficientAuthenticationException) {
                            map.put("msg", "访问失败,请先登录!");
                        } else {
                            map.put("msg", "访问失败!");
                        }
                        out.write(new ObjectMapper().writeValueAsString(map));
                        out.flush();
                        out.close();
                    }
                });
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        // 配置不需要拦截的请求地址,即该地址不走 Spring Security 过滤器链
        web.ignoring().antMatchers("/vercode");
    }
}

3 测试

新增 HelloController 测试类,如下:

@RestController
public class HelloController {
    @GetMapping("/hello")
    public String hello() {
        return "hello";
    }

    @GetMapping("/admin/hello")
    public String admin() {
        return "hello admin";
    }

    @GetMapping("/user/hello")
    public String user() {
        return "hello user";
    }

    @GetMapping("/login")
    public String login() {
        return "please login";
    }
}

项目启动之后,用 Postman 完成测试,如下:

访问 /hello 接口,提示先登录。

访问 /doLogin 接口登录失败,因为 key 不对。

用自定义的 key 访问 /doLogin 接口登录成功。

再访问 /hello 接口,返回正常。
