用httpclient实现的忽视ssl的java代码

好的，下面是使用 Apache HttpClient 实现忽略 SSL 验证的 Java 代码示例：

import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContexts;

import javax.net.ssl.SSLContext;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;

public class HttpUtils {

    public static String sendGet(String url) throws Exception {
        SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, (certificate, authType) -> true).build();
        SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE);

        HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslConnectionSocketFactory).build();

        HttpGet request = new HttpGet(url);

        BufferedReader in = new BufferedReader(new InputStreamReader(httpClient.execute(request).getEntity().getContent()));

        String inputLine;
        StringBuilder response = new StringBuilder();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        return response.toString();
    }
}

使用示例：

String url = "https://api.example.com/data";
String response = HttpUtils.sendGet(url);
System.out.println(response);

这是一个简单的使用 Apache HttpClient 实现忽略 SSL 验证的 http 工具类。你可以根据自己的需要进行修改或扩展。
