如何在Spring OAuth中相对重定向到授权端点？

@Bean
public AuthorizationEndpoint authorizationEndpoint() {
    AuthorizationEndpoint authorizationEndpoint = new AuthorizationEndpoint();
    // 设置授权端点的URL路径
    authorizationEndpoint.setBaseUri("/oauth/authorize");
    return authorizationEndpoint;
}

@Controller
public class RedirectController {

    @GetMapping("/redirect")
    public RedirectView redirectToAuthorizationEndpoint() {
        RedirectView redirectView = new RedirectView();
        // 设置相对重定向的URL路径
        redirectView.setUrl("/oauth/authorize");
        return redirectView;
    }
}

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/oauth/authorize").authenticated()
                .anyRequest().permitAll()
                .and()
            .formLogin()
                .and()
            .csrf().disable();
    }
}
