在 formLogin這里還可以配置詳細(xì)一點(diǎn)

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("yzn").password("123").roles("admin")
                .and()
                .withUser("test").password("123").roles("user");
    }

    @Bean
    PasswordEncoder passwordEncoder(){
        return NoOpPasswordEncoder.getInstance();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin/**").hasRole("admin")
                .antMatchers("/user/**").hasAnyRole("admin", "user")
                .anyRequest().authenticated()
                .and()
                .formLogin()
                // 登錄處理接口
                .loginProcessingUrl("/doLogin")
                // 定義登錄頁(yè)面，未登錄時(shí)，訪問(wèn)一個(gè)需要登錄之后才能訪問(wèn)的接口，會(huì)自動(dòng)跳轉(zhuǎn)到該頁(yè)面
                .loginPage("/login")
                //定義登錄時(shí)，用戶名的 key，默認(rèn)為 username
                .usernameParameter("uname")
                //定義登錄時(shí)，用戶密碼的 key，默認(rèn)為 password
                .passwordParameter("passwd")
                //登錄成功的處理器
                .successHandler(new AuthenticationSuccessHandler() {
                    @Override
                    public void onAuthenticationSuccess(HttpServletRequest req, HttpServletResponse res, Authentication authentication) throws IOException, ServletException {
                        res.setContentType("application/json;charset=utf-8");
                        PrintWriter out = res.getWriter();
                        out.write("success");
                        out.flush();
                    }
                })
                .failureHandler(new AuthenticationFailureHandler() {
                    @Override
                    public void onAuthenticationFailure(HttpServletRequest req, HttpServletResponse res, AuthenticationException e) throws IOException, ServletException {
                        res.setContentType("application/json;charset=utf-8");
                        PrintWriter out = res.getWriter();
                        out.write("fail");
                        out.flush();
                    }
                })
                //和表單登錄相關(guān)的接口統(tǒng)統(tǒng)都直接通過(guò)
                .permitAll()
                .and()
                .csrf().disable();
    }
}

@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!!!";
    }
}

利用postman測(cè)試

注銷表單配置
