基于配置的权限控制

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private JwtAuthenticationTokenFilter jwtAuthenticationTokenFilter;

    @Autowired
    private AuthenticationEntryPoint authenticationEntryPoint;

    @Autowired
    private AccessDeniedHandler accessDeniedHandler;

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

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // 关闭csrf
        http.csrf().disable()
                // 不通过session获取SecurityContext
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                // 对于登录接口,允许匿名访问
                .antMatchers("/user/login").anonymous()
                // 配置test接口的权限
                .antMatchers("/test").hasAuthority("system:dept:list")
                // 除上面外的所有请求全部需要鉴权认证
                .anyRequest().authenticated();

        // 配置认证过滤器在UsernamePasswordAuthenticationFilter之前
        http.addFilterBefore(jwtAuthenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);

        http.exceptionHandling()
                // 认证失败处理器
                .authenticationEntryPoint(authenticationEntryPoint)
                // 授权异常处理器
                .accessDeniedHandler(accessDeniedHandler);

        // 允许跨域
        http.cors();
    }

}

经过测试发现，如果同时使用了上面的类配置权限和使用@PreAuthorize注解，注解配置的优先生效。推荐使用注解进行权限控制。
