禁用URL Spring Security JAVA配置的X-FrameOptions响应标头

Question

I am trying to disable or set the XFrameOptions header to SAME_ORIGIN for a particular URL in my Spring Boot project with Spring Security. I am pasting the code below,

@Configuration
@EnableWebSecurity    
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {    
    @Override
    protected void configure(HttpSecurity http) throws Exception {            
        RequestMatcher matcher = new AntPathRequestMatcher("**/course/embed/**");

        DelegatingRequestMatcherHeaderWriter headerWriter =
                new DelegatingRequestMatcherHeaderWriter(matcher,new XFrameOptionsHeaderWriter());

        http.headers()
                .frameOptions().sameOrigin()
                .addHeaderWriter(headerWriter);
    }    
}

I am using AntRequestMatcher but that does not work, it instead disabled the XFrameOptions header for all the responses. Is there a better way to do this? Please help.

You need to configure multiple HttpSecurity instances. The key is to extend the WebSecurityConfigurationAdapter multiple times. For example, the following is an example of having a different configuration for URL's that match with **/course/embed/** . If matches X-Frame-Options will be SAMEORIGIN, otherwise DENY.

@EnableWebSecurity
public class WebMVCSecurity {
    //Configure Authentication as normal, optional, showing just as a sample to indicate you can add other config like this
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("user").password("password").roles("USER").and()
                .withUser("admin").password("password").roles("USER", "ADMIN");
    }

    // Create an instance of WebSecurityConfigurerAdapter that contains @Order to specify which WebSecurityConfigurerAdapter should be considered first.
    @Configuration
    @Order(1)
    public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
        protected void configure(HttpSecurity http) throws Exception {
            // The http.antMatcher states that this HttpSecurity will only be applicable to URLs that match with **/course/embed/**
            http.antMatcher("**/course/embed/**").headers().frameOptions().sameOrigin();
        }
    }

    // Create another instance of WebSecurityConfigurerAdapter. 
    // If the URL does not match with **/course/embed/** this configuration will be used. 
    // This configuration is considered after ApiWebSecurityConfigurationAdapter since it has an @Order value after 1 (no @Order defaults to last).
    @Configuration
    public static class FormLoginWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests()
                    .anyRequest().authenticated()
                    .and()
                    .formLogin();

            //bla bla bla ...
        }
    }
}
