-oriented programming language is still used, the underlying database is still used, and the ORM tool is indispensable in the middle. With the ORM framework, the program is no longer directly accessing the database, but the object-oriented operation of persistent objects (such as additions and deletions), and the ORM framework is to translate these object-oriented operations into the underlying SQL operations. the ORM definition: ORM: Object-Relational Mapping (English: Relational Mapping) is a
pay attention to in IOC. For example, Spring provides three injection methods. However, normal people only use one method (although hibernatetemple seems to have been implemented in all three methods ), we only use one method, Set Value injection, that is, get and set method injection. Here, my thoughts are divided into two parts: I. Logic (CODE) Ii. Spring or struts configuration section. IOC requires us to know the class to be initialized in advance, First, let's take a look at two sections o

You can use the following file by default! # HostKey/etc/ssh/ssh_host_key # private key used by SSH version 1 # HostKey/etc/ssh/ssh_host_rsa_key # RSA private key used by SSH version 2 #
Always want to transfer their server SSH authentication mode from user name password mode to RSA and DSA authentication protocol, through the release of OpenSSH 4.2, today wrote a configuration process and collected some reference articles on RSA and DSA.Idea Finishing:Has not understood the authentication process in the public key mode, here summarizes the method of making and placing the public key and the secret key. The following assumptions are g

SSH is a secure channel protocol that is used primarily for remote logins. In the Rhel 5 system, the OPENSSH server is provided by software packages such as OpenSSH, Openssh-server, which are installed by default, and the sshd is added as a standard system service. Use the following methods: $ SSH Host $ ssh Username@host $
1.SSH Remote ManagementSSH (Secure Sheel) is a secure channel protocol, which is mainly used to realize remote login of character interface, and so on. The SSH protocol encrypts the data transmitted by both parties, including the user's password. Applications such as the early Telnet (telnet, tcp23 port), RSH (remote sheel, remotely execute command), RCP (remote file copy, long-range files replication) pres

SSH to the 192.168.88.61 machine requires a password, which is inconvenient for some scripts because of the need for a password, which requires manual intervention.

SSH to the 163 host requires a password, which is inconvenient for some scripts because the password is required, that is, manual intervention is required. The method used previously was to copy the authorized_keys file (I can't remember it, I used it before). Recently, I found a command ssh-copy-ID is very convenient. I tried it and it really worked well. It was recorded below: On 192.168.42.142 1) Run
