Spring Boot security 默认拦截静态资源的解决方法

来源：jb51　　时间：2023/3/17 8:57:30　　对本文有异议

Spring Boot security 会默认登陆之前拦截全部css， js，img等动态资源，导致我们的公开主页在登陆之前很丑陋

像这样：

网上很多解决办法都过时了比如还在使用WebSecurityConfigurerAdapte，antMatchers

public class SecurityConfigurer extends WebSecurityConfigurerAdapter {
    @Override
    public void configure(WebSecurity web) throws Exception {
    web
        .ignoring()
        .antMatchers("/resources/**");
}
}

WebSecurityConfigurerAdapter和antMatchers已经被Spring Security 6.0弃用，现最新的是使用securityFilterChain class 如下图：

public class WebSecurityConfig {
 
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests((requests) -> requests
                .requestMatchers("/", "/home").permitAll()
                .anyRequest().authenticated()
            )
            .formLogin((form) -> form
                .loginPage("/login")
                .permitAll()
            )
            .logout((logout) -> logout.permitAll());
 
        return http.build();
    }
}

这里只需要添加.requestMatchers("/resources/**").permitAll()就可以允许访问resources文件下资源

注意.antMatchers 已经弃用，用.requestMatchers代替

 public class WebSecurityConfig {
 
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests((requests) -> requests
                .requestMatchers("/", "/home").permitAll()
                 //放行静态资源
                .requestMatchers("/resources/**").permitAll()
                .anyRequest().authenticated()
            )
            .formLogin((form) -> form
                .loginPage("/login")
                .permitAll()
            )
            .logout((logout) -> logout.permitAll());
 
        return http.build();
    }
}
