<security:authorize access="hasPermission('or','formDialog:edit')">其中的hasPermission如何调用自定义的 MyPermissionEvaluator方法

要使用自定义的 MyPermissionEvaluator 方法，需要在 Spring Security 的配置文件中配置一个 bean，用于指定自定义的 PermissionEvaluator 实现。

例如，假设 MyPermissionEvaluator 的实现类名为 CustomPermissionEvaluator，那么在 Spring Security 的配置文件中，可以这样配置：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    ...

    @Bean
    public CustomPermissionEvaluator customPermissionEvaluator() {
        return new CustomPermissionEvaluator();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/admin/**").hasRole("ADMIN")
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .logout()
                .logoutUrl("/logout")
                .permitAll();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
                .withUser("user").password("{noop}password").roles("USER")
                .and()
                .withUser("admin").password("{noop}password").roles("USER", "ADMIN");
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web
            .ignoring()
                .antMatchers("/resources/**");
    }

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

    @Bean
    public UserDetailsService userDetailsService() {
        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(User.withUsername("user").password("{noop}password").roles("USER").build());
        manager.createUser(User.withUsername("admin").password("{noop}password").roles("USER", "ADMIN").build());
        return manager;
    }

    @Bean
    public PermissionEvaluator permissionEvaluator() {
        return new CustomPermissionEvaluator();
    }
}

然后在权限表达式中，就可以使用自定义的 hasPermission 表达式了：

<security:authorize access="hasPermission('or','formDialog:edit')">...</security:authorize>
