关于PKIX path building failed的问题

最近在做一个https的接口，对方说不需要证书，但是我这边链接不过去，只能自己写一个假的安全证书绕过去，代码如下：

package com.ywwy.common.service;


import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;


import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import com.icip.signature.encrypt.Encryption;
import com.ieslab.eim.common.util.FileTypeWrite;
