ResourceServerConfigurerAdapter 与 WebSecurityConfigurerAdapter

使用Spring Security来保护应用程序的资源和提供身份验证和授权是一项重要的任务。在Spring Security中，有两个主要的配置类，分别是ResourceServerConfigurerAdapter和WebSecurityConfigurerAdapter。这两个类允许我们通过编写自定义配置来保护我们的应用程序，并根据需要进行身份验证和授权。

java
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
    
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/api/**").authenticated()
                .anyRequest().permitAll();
    }
}

java
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/admin/**").hasRole("ADMIN")
                .antMatchers("/user/**").hasRole("USER")
                .anyRequest().permitAll()
                .and()
            .formLogin()
                .loginPage("/login")
                .defaultSuccessUrl("/home")
                .permitAll()
                .and()
            .logout()
                .logoutUrl("/logout")
                .permitAll();
    }
    
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
                .withUser("admin").password("{noop}admin123").roles("ADMIN")
                .and()
                .withUser("user").password("{noop}user123").roles("USER");
    }
}

java
@Configuration
@EnableResourceServer
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter implements ResourceServerConfigurer {
    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        resources.resourceId("my-resource-id");
    }
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/api/**").authenticated()
                .antMatchers("/admin/**").hasRole("ADMIN")
                .antMatchers("/user/**").hasRole("USER")
                .anyRequest().permitAll()
                .and()
            .formLogin()
                .loginPage("/login")
                .defaultSuccessUrl("/home")
                .permitAll()
                .and()
            .logout()
                .logoutUrl("/logout")
                .permitAll();
    }
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
                .withUser("admin").password("{noop}admin123").roles("ADMIN")
                .and()
                .withUser("user").password("{noop}user123").roles("USER");
    }
}
