Spring Security 自定义登录页怎么验证

• 1、Spring Security配置
• 2、登录页 login.html

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    UserServiceImpl userService;

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userService).passwordEncoder(passwordEncoder());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()     
                .formLogin()
                .loginPage("/login")
                .loginProcessingUrl("/authentication/form")
                .permitAll()
                .and()
                .csrf().disable();
    }
}

.loginPage()：中的url是自己写的login.html页面

  
   
          
      
      登录
  

这里的action与配置类的 .loginProcessingUrl必须对应
该接口不用自己写，Spring Security会自行完成登录验证。
