限制URL列表的JSON格式可以根据您的需求进行定义。以下是一个示例：

{ "restrictions": [ { "url": "/api/endpoint1", "params": { "param1": "value1", "param2": "value2" } }, { "url": "/api/endpoint2", "params": { "param3": "value3" } } ] }

在上述示例中，"restrictions"是一个包含限制URL的数组。每个限制URL对象都具有"url"和"params"属性。"url"表示要限制的URL路径，"params"是一个包含参数和值的对象。您可以根据需要添加更多的限制URL对象。

在Spring Boot框架中，您可以使用拦截器（Interceptor）来控制限制URL列表。下面是一个简单的示例：

首先，创建一个拦截器类，实现`HandlerInterceptor`接口。在`preHandle`方法中，您可以读取限制URL列表的JSON文件，并在请求到达时进行匹配检查。如果匹配成功，您可以执行相应的操作，例如拒绝请求或执行其他逻辑。

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.List;
import java.util.Map;public class RestrictionInterceptor implements HandlerInterceptor {private static final String RESTRICTION_FILE_PATH = "/path/to/restriction.json";@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {// Read the restriction JSON fileString restrictionJson = new String(Files.readAllBytes(Paths.get(RESTRICTION_FILE_PATH)));// Parse the JSON into a list of restrictionsList<Map<String, Object>> restrictions = new ObjectMapper().readValue(restrictionJson, new TypeReference<List<Map<String, Object>>>() {});// Get the request URL and parametersString requestUrl = request.getRequestURI();Map<String, String[]> requestParams = request.getParameterMap();// Check if the request matches any restrictionfor (Map<String, Object> restriction : restrictions) {String restrictionUrl = (String) restriction.get("url");Map<String, Object> restrictionParams = (Map<String, Object>) restriction.get("params");// Check if the request URL matches the restriction URLif (requestUrl.equals(restrictionUrl)) {// Check if the request parameters match the restriction parametersboolean paramsMatch = true;for (Map.Entry<String, Object> paramEntry : restrictionParams.entrySet()) {String paramName = paramEntry.getKey();Object paramValue = paramEntry.getValue();if (!requestParams.containsKey(paramName) || !requestParams.get(paramName)[0].equals(paramValue)) {paramsMatch = false;break;}}// If both URL and parameters match, allow the requestif (paramsMatch) {return true;}}}// If no restriction match found, reject the requestresponse.sendError(HttpServletResponse.SC_FORBIDDEN, "Access denied");return false;}@Overridepublic void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {// This method is called after the handler is executed}@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {// This method is called after the complete request is finished}
}

然后，将拦截器注册到Spring Boot应用程序中。在您的配置类（通常是一个继承自`WebMvcConfigurerAdapter`的类）中，重写`addInterceptors`方法，并添加您的拦截器。

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(new RestrictionInterceptor()).addPathPatterns("/**");}
}

在上述示例中，`RestrictionInterceptor`是您创建的拦截器类。通过调用`addInterceptor`方法将其添加到`InterceptorRegistry`中，并使用`addPathPatterns`方法指定要拦截的URL模式（在此示例中，拦截所有URL）。

这样，当请求到达时，拦截器将会被触发，并根据限制URL列表进行匹配检查。根据匹配结果，您可以执行相应的操作。

请注意，上述示例是一个简化的实现，仅用于演示目的。您可以根据实际需求进行修改和扩展。另外，您需要根据实际情况替换`RESTRICTION_FILE_PATH`为限制URL列表的JSON文件路径。
