springboot+websocket實現點對點聊天

說明:在群聊的基礎上進行改進，點對點要建立在Security的基礎上

websocket配置文件中

 

 security配置文件中

@Configuration
public class WebSecurity extends WebSecurityConfigurerAdapter {

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

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("duanbochao")
                .password("123")
                .roles("admin")
                .and()
                .withUser("lizi")
                .password("123")
                .roles("duan");
    }
    @Override
    public void configure(org.springframework.security.config.annotation.web.builders.WebSecurity web) throws Exception {
        super.configure(web);
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .anyRequest().authenticated()
                .and()
                .formLogin().permitAll();
    }
}

創建一個bean

 

 controller中

 

 index.html文件中

 

 登錄后測試，當前用戶lizi

 

 

 

 更換其他人則不能正常發送！

至此，ok.
