generated by itself, not by the CA-certified organization. So the server doesn't agree with him. Intercepted it. So the SSL link has an error. So here's the problem ... Test in the test environment again. However, there is no certificate of CA certification in the production environment. How about that. Find some good posts. Solved the problem. Controlling in code, skipping SSL validation Creates a new proxy class. The checksum method used to override SSL is to make the method empty, Getaccep

In the process of developing or using SSL, many software require us to provide Java KeyStore, especially some java-based middleware products. Our usual practice is to do the JDK's own tool command (Keytool), for example, the following exampleKeytool-import-v-alias entrust2048-file D:\certs\EnTrust2048.cer-keystore D:\certs\test.jksKeytool-import-v-alias Entrustcertificationauthorityl1c-file D:\
