私はSpring-Securityに非常に慣れていません。JWTを実行するためにspring-bootアプリケーションに実装しようとしていますauthentication。私はサンプルコードに従いましたjwt. HttpRequestしかし、サンプル ファイルで行われた構成に従って、構成内のメモリ内データ セットを使用して入力を検証できます。しかし、 をチェックして、 に存在する値でusernameをpassword送信する方法がわかりません。私を案内してください。私の構成クラスはrequestdatabase
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable().authorizeRequests()
.antMatchers("/").permitAll()
.antMatchers(HttpMethod.POST, "/login").permitAll()
.anyRequest().authenticated()
.and()
// We filter the api/login requests
.addFilterBefore(new JWTLoginFilter("/login", authenticationManager()),
UsernamePasswordAuthenticationFilter.class)
// And filter other requests to check the presence of JWT in header
.addFilterBefore(new JWTAuthenticationFilter(),
UsernamePasswordAuthenticationFilter.class);
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// Create a default account
auth.inMemoryAuthentication()
.withUser("admin")
.password("password")
.roles("ADMIN");
}
}
ここでオーバーライドされた で、 forパスconfigure(AuthenticationManagerBuilder auth) throws Exceptionに存在する資格情報と比較される資格情報を設定できますrequest/login
