SpringSecurity实现匿名访问的方式如下

/**
 * spring security配置
 * {@link EnableGlobalMethodSecurity } 如果想要启用spring方法级安全时，使用这个注解
 *
 * @author ruoyi
 */
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {  
    
    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity                
                .authorizeRequests()
                // 对于登录login 验证码captchaImage 允许匿名访问
                .antMatchers("/login", "/captchaImage").anonymous();
    }
}

如果有很多个路径都需要匿名访问，那岂不是要在 antMatchers 加很多路径？这样太繁琐

使用注解方式实现匿名访问，步骤如下:

• 先定义一个注解

/**
 * Security允许匿名访问
 */
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface AnonymousAccess {
}

• 修改 security 配置类

/**
 * spring security配置
 * {@link EnableGlobalMethodSecurity } 如果想要启用spring方法级安全时，使用这个注解
 *
 * @author ruoyi
 */
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {  
    
    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity                
                .authorizeRequests()
                // 对于登录login 验证码captchaImage 允许匿名访问
                .antMatchers("/login", "/captchaImage").anonymous()
                // 所有加 AnonymousAccess 注解的请求都允许匿名访问
                .antMatchers(getAnonymousUrls()).anonymous();
    }

    /**
     * 获取标有注解 AnonymousAccess 的访问路径
     */
    private String[] getAnonymousUrls() {
        // 获取所有的 RequestMapping
        Map<RequestMappingInfo, HandlerMethod> handlerMethods = SpringUtils.getBean(RequestMappingHandlerMapping.class).getHandlerMethods();
        Set<String> allAnonymousAccess = new HashSet<>();
        // 循环 RequestMapping
        for (Map.Entry<RequestMappingInfo, HandlerMethod> infoEntry : handlerMethods.entrySet()) {
            HandlerMethod value = infoEntry.getValue();
            // 获取方法上 AnonymousAccess 类型的注解
            AnonymousAccess methodAnnotation = value.getMethodAnnotation(AnonymousAccess.class);
            // 如果方法上标注了 AnonymousAccess 注解，就获取该方法的访问全路径
            if (methodAnnotation != null) {
                allAnonymousAccess.addAll(infoEntry.getKey().getPatternsCondition().getPatterns());
            }
        }
        return allAnonymousAccess.toArray(new String[0]);
    }
}

• 使用

@RestController
@RequestMapping("/consignment")
public class RmbssDcDepotController extends BaseController {

    @Autowired
    private IRmbssDcDepotService rmbssDcDepotService;

    /**
     * 查询所有有效的代储车间
     * @AnonymousAccess 允许匿名访问的注解
     */
    @AnonymousAccess 
    @GetMapping("/plantList")
    public AjaxResult plantList(RmbssDcDepot rmbssDcDepot) {
        return AjaxResult.success(rmbssDcDepotService.selectDcPlantList(rmbssDcDepot));
    }
}
