Angular 6和基于Spring Boot的记住我功能与基于会话的登录可以通过以下步骤来实现：

1. 在Angular 6中，您需要创建一个登录表单组件和一个记住我复选框。可以使用Angular Material库来创建漂亮的表单组件。

login.component.html:

  
    
  
  
    
  
  Remember me
  Login

login.component.ts:

import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { AuthService } from 'path-to-auth-service';

@Component({
  selector: 'app-login',
  templateUrl: './login.component.html',
  styleUrls: ['./login.component.css']
})
export class LoginComponent implements OnInit {
  loginForm: FormGroup;

  constructor(private formBuilder: FormBuilder, private authService: AuthService) { }

  ngOnInit() {
    this.loginForm = this.formBuilder.group({
      username: ['', Validators.required],
      password: ['', Validators.required],
      rememberMe: [false]
    });
  }

  login() {
    const username = this.loginForm.controls['username'].value;
    const password = this.loginForm.controls['password'].value;
    const rememberMe = this.loginForm.controls['rememberMe'].value;

    this.authService.login(username, password, rememberMe);
  }
}

2. 在Spring Boot中，您需要创建一个登录控制器和一个自定义的RememberMeServices来处理记住我功能。

RememberMeServices.java:

import org.springframework.security.core.Authentication;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.rememberme.InMemoryTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;
import org.springframework.security.web.authentication.rememberme.TokenBasedRememberMeServices;

public class RememberMeServices extends TokenBasedRememberMeServices {

  public RememberMeServices(String key, UserDetailsService userDetailsService) {
    super(key, userDetailsService);
    setTokenRepository(createTokenRepository());
  }

  private PersistentTokenRepository createTokenRepository() {
    // 如果您使用内存存储Token，请使用InMemoryTokenRepositoryImpl
    // 如果您使用数据库存储Token，请使用JdbcTokenRepositoryImpl
    return new InMemoryTokenRepositoryImpl();
  }

  @Override
  protected boolean rememberMeRequested(HttpServletRequest request, String parameter) {
    // 检查请求中是否包含记住我参数
    String rememberMe = request.getParameter(parameter);
    return rememberMe != null && rememberMe.equalsIgnoreCase("true");
  }
}

SecurityConfig.java:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

  @Value("${rememberme.key}")
  private String rememberMeKey;

  @Autowired
  private UserDetailsService userDetailsService;

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http
      .authorizeRequests()
        .antMatchers("/login").permitAll()
        .anyRequest().authenticated()
        .and()
      .formLogin()
        .loginPage("/login")
        .and()
      .rememberMe()
        .rememberMeServices(rememberMeServices())
        .key(rememberMeKey);
  }

  @Override
  protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService);
  }

  public RememberMeServices rememberMeServices() {
    return new RememberMeServices(rememberMeKey, userDetailsService);
  }
}

3. 创建一个用于处理登录请求的控制器。

LoginController.java:

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class LoginController {

  @GetMapping("/login")
  public String login() {
    return "login";
  }
}
