springboot整合spring security 实现用户登录注册与鉴权全记录

首先，你需要在pom.xml文件中添加以下依赖项来引入Spring Boot和Spring Security：

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-securityartifactId>
dependency>

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-data-jpaartifactId>
dependency>

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-webartifactId>
dependency>

接下来，你需要创建一个实体类来表示用户信息，并使用JPA来持久化用户数据。

@Entity
@Table(name = "users")
public class User implements UserDetails {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(unique = true)
    private String username;

    private String password;

    // getter and setter methods

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return Collections.singleton(new SimpleGrantedAuthority("ROLE_USER"));
    }

    @Override
    public String getPassword() {
        return password;
    }

    @Override
    public String getUsername() {
        return username;
    }

    // other methods from UserDetails interface
}

然后，你需要创建一个实现了UserDetailsService接口的类来处理用户认证。

@Service
public class CustomUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userRepository.findByUsername(username);
        if (user == null) {
            throw new UsernameNotFoundException("User not found");
        }
        return user;
    }
}

接下来，你需要创建一个控制器类来处理用户注册和登录的请求。

@RestController
public class AuthController {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private CustomUserDetailsService userDetailsService;

    @PostMapping("/register")
    public ResponseEntity<?> registerUser(@RequestBody User user) {
        // 在这里你可以添加验证逻辑，如检查用户名是否已存在等
        userDetailsService.save(user);
        return ResponseEntity.ok("User registered successfully");
    }

    @PostMapping("/login")
    public ResponseEntity<?> authenticateUser(@RequestBody LoginForm loginForm) {
        Authentication authentication = authenticationManager.authenticate(
                new UsernamePasswordAuthenticationToken(loginForm.getUsername(), loginForm.getPassword()));
        SecurityContextHolder.getContext().setAuthentication(authentication);
        return ResponseEntity.ok("User authenticated successfully");
    }
}

最后，你需要配置Spring Security来限制访问和处理认证请求。

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private CustomUserDetailsService userDetailsService;

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

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

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

以上就是整合Spring Security实现用户登录注册和鉴权的示例代码。你可以根据实际需求进行适当的调整和扩展。
