可以在DocumentBuilder上设置超时。DocumentBuilder是一个用于解析XML文档的Java类,它提供了一系列的方法来创建和配置DOM解析器。在使用DocumentBuilder解析XML文档时,可以通过设置超时来限制解析器的解析时间,以防止潜在的安全风险和性能问题。
以下是如何在DocumentBuilder上设置超时的示例代码:
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
public class DocumentBuilderTimeoutExample {
public static void main(String[] args) {
try {
