这似乎是一个平庸的解决方案，似乎是一个常见的问题，但它确实有效。在swagger配置中启用此filterClass：

package com.example;

import io.swagger.v3.core.filter.AbstractSpecFilter;
import io.swagger.v3.oas.models.OpenAPI;
import io.swagger.v3.oas.models.PathItem;
import io.swagger.v3.oas.models.Paths;

import java.util.List;
import java.util.Map;
import java.util.Map.Entry;
import java.util.Optional;

public class PathSpecFilter extends AbstractSpecFilter {
    private static final String PUBLIC_PATH = "/thePublicApiPrefix";

    @Override
    public Optional<OpenAPI> filterOpenAPI(final OpenAPI openAPI, final Map<String, List<String>> params, final Map<String, String> cookies, final Map<String, List<String>> headers) {
        final Optional<OpenAPI> opt = super.filterOpenAPI(openAPI, params, cookies, headers);
        return opt.map(openapi -> {
            openapi.setPaths(fix(openapi.getPaths()));
            return openapi;
        });
    }

    private Paths fix(final Paths paths) {
        final Paths next = new Paths();

        for (final Entry<String, PathItem> entry : paths.entrySet()) {
            final String key = entry.getKey().startsWith(PUBLIC_PATH)
                    ? entry.getKey().substring(PUBLIC_PATH.length())
                    : entry.getKey();
            next.put(key, entry.getValue());
        }

        return next;
    }
}
