Spring Security 配置多WebSecurityConfigurerAdapter

Spring Security多入口

官方爲了方便演示使用的是一個主類,兩個內部類來實現的多入口,下面的例子將其拆分爲兩個配置類,兩個用戶方便理解.

配置

@Configuration
public class FormSecurityConfig extends WebSecurityConfigurerAdapter {

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().disable()
                .csrf().disable()
                .authorizeRequests().antMatchers("/form/**")
                .hasRole("USER")
                .and()
                .formLogin().successForwardUrl("/form/index");
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .inMemoryAuthentication()
                .withUser("user")
                .password(passwordEncoder().encode("user"))
                .roles("USER");
    }
}

說明:

• 上面的配置爲系統指定了user爲默認用戶,擁有USER權限,
• 指定以form起始的路徑需要校驗USER權限
• 增加formLogin,指定/form/index爲登陸成功指向的頁面

@Order(1)
@Configuration
public class BasicSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .antMatcher("/basic/**")
                .authorizeRequests().anyRequest()
                .hasRole("BASIC")
                .and()
                .httpBasic();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .inMemoryAuthentication()
                .withUser("basic")
                .password(passwordEncoder.encode("basic"))
                .roles("BASIC");
    }
}

說明:

• 使用@Order(1)指定了加載順序
• 上面的配置爲系統指定了basic爲默認用戶,擁有BASIC權限,
• 指定以basic起始的路徑需要校驗BASIC權限
• 增加httpBasic驗證

注意事項

1. HttpSecurity配置以authorizeRequests爲起始表示針對所有請求路徑
2. HttpSecurity配置以antMatcher("/basic/**")爲新增一個入口
3. FormSecurityConfig 未寫@Order繼承WebSecurityConfigurerAdapter中註解序號爲100
4. 由於formLogin會增加默認登陸頁過濾器/login所以不能使用其它路徑作爲起始,否則會導致默認登錄頁不生效
5. 如果authorizeRequests加載順序靠前會導致後續配置的antMatcher對應的路徑失效.
