spring-boot - Spring Boot 在流程完成之前返回响应

Question

我正在使用 Spring Boot 来处理证书和客户端postman以与服务交互，假设privatekey，publickey并且certificate已经处理decrypted，然后使用CertificateHelper getCertificate()函数来parseX509Certificate

private List<Certificate> getCA(X509Certificate cert, Date tsp) {
    Security.addProvider(new BouncyCastleProvider());
    try {
        String cnIssuer = X500Name.asX500Name(cert.getIssuerX500Principal()).getCommonName();
        int xTry = 0;
        while ((resultCA == null || resultCA_C5 == null || resultCA_C3 == null || resultCA_v1 == null) && xTry <= 3) {
            LOGGER.info(LogSystem.getLog("TRY                :" + xTry, tsp, "LOG"));
            try {
                loadCAinit();
            } catch (KeyManagementException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (UnrecoverableKeyException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (CertificateException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (KeyStoreException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (NoSuchAlgorithmException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (NoSuchProviderException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            xTry++;
        }

        if (xTry > 3) {
            return null;
        }

        for (int i = 0; i < 4; i++) {
            List<Certificate> CACheck;
            if (i == 0) {
                CACheck = resultCA;
            } else if (i == 1) {
                CACheck = resultCA_C3;
            } else if (i == 2) {
                CACheck = resultCA_C5;
            } else {
                CACheck = resultCA_v1;
            }
            LOGGER.info(LogSystem.getLog("CA CHECK : " + CACheck.get(0).toString(), tsp, "LOG"));

            X509Certificate  certCA;
            try {
                LogSystem.info("Process getcertificate on certificate helper");
                certCA = (X509Certificate) CertificateHelper.getCertificate(CACheck.get(0).getCertificateData());
                LogSystem.info("End process getcertificate on certificate helper");

                String cnIssuerCheck = X500Name.asX500Name(certCA.getSubjectX500Principal()).getCommonName();
                System.out.println("         CA CN: " + cnIssuerCheck);
                System.out.println("User Issuer CN: " + cnIssuer);
                if (cnIssuer.equals(cnIssuerCheck)) {
                    LOGGER.info(LogSystem.getLog("DN CA:" + certCA.getSubjectDN().toString() + ", SN: " + certCA.getSerialNumber().toString(16).toUpperCase(), tsp, "LOG"));
                    LOGGER.info(LogSystem.getLog("DN User:" + cert.getSubjectDN().toString() + ", SN: " + cert.getSerialNumber().toString(16).toUpperCase(), tsp, "LOG"));
                    return CACheck;

                }
            } catch (CertificateException e) {
                // TODO Auto-generated catch block
                LOGGER.info(LogSystem.getLog("      CATCH 1", tsp,"LOG"));
                e.getCause();
                e.printStackTrace();
                System.out.println("asas");
            }

        }
        LOGGER.info(LogSystem.getLog("Issuer " + cnIssuer + " not found : " + cert.getIssuerDN(), tsp, "LOG"));
        System.out.println("asas");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        LOGGER.info(LogSystem.getLog("      CATCH 2", tsp,"LOG"));
        e.printStackTrace();
        System.out.println("asas");
    }
    LOGGER.info(LogSystem.getLog("      RETURN NULL", tsp,"LOG"));
    System.out.println("asas");
    return null;
}

getCertificate()课堂上的功能CertificateHelper

package org.ejbca.core.protocol.ws.common;

import java.security.cert.Certificate;
import java.security.cert.CertificateException;
import org.cesecore.util.Base64;
import org.cesecore.util.CertTools;

public class CertificateHelper {
    public static final String RESPONSETYPE_CERTIFICATE = "CERTIFICATE";
    public static final String RESPONSETYPE_PKCS7 = "PKCS7";
    public static final String RESPONSETYPE_PKCS7WITHCHAIN = "PKCS7WITHCHAIN";
    public static final int CERT_REQ_TYPE_PKCS10 = 0;
    public static final int CERT_REQ_TYPE_CRMF = 1;
    public static final int CERT_REQ_TYPE_SPKAC = 2;
    public static final int CERT_REQ_TYPE_PUBLICKEY = 3;

    public CertificateHelper() {
    }

    public static Certificate getCertificate(byte[] certificateData) throws CertificateException {
        Certificate retval = CertTools.getCertfromByteArray(Base64.decode(certificateData), Certificate.class);
        return retval;
    }

    public static byte[] getPKCS7(byte[] pkcs7Data) {
        return Base64.decode(pkcs7Data);
    }
}

ongetCertificate()函数调用另一个类CertTools函数getCertfromByteArray()

 public static <T extends Certificate> T getCertfromByteArray(byte[] cert, Class<T> returnType) throws CertificateParsingException {
        return getCertfromByteArray(cert, "BC", returnType);
    }

和详细功能getCertfromByteArray()

public static <T extends Certificate> T getCertfromByteArray(byte[] cert, String provider, Class<T> returnType) throws CertificateParsingException {
        T ret = null;
        String prov = provider;
        if (provider == null) {
            prov = "BC";
        }

        if (returnType.equals(X509Certificate.class)) {
            ret = parseX509Certificate(prov, cert);
        } else if (returnType.equals(CardVerifiableCertificate.class)) {
            ret = parseCardVerifiableCertificate(prov, cert);
        } else {
            try {
                ret = parseX509Certificate(prov, cert);
            } catch (CertificateParsingException var8) {
                try {
                    ret = parseCardVerifiableCertificate(prov, cert);
                } catch (CertificateParsingException var7) {
                    throw new CertificateParsingException("No certificate could be parsed from byte array. See debug logs for details.");
                }
            }
        }

        return (Certificate)ret;
    }

• 在第 779 行处理获取日志打印
• 第 780 行的进程无法执行，然后客户端得到返回的响应http code 200
• 第 781 行的散文没有执行，因为第 780 行

任何建议为什么从第 780 行以空正文和 http 代码成功 200 回复我的邮递员？
