Easily complete java database operation, must-see series white

Today to talk about the java connection with the operation of the JDBC driver to connect to the database. This article takes only five minutes can finish up in.

First, a new package lib in our code block, FIG.

Then download the corresponding mysql database-driven, in general, because I use the MySQL database version, database-driven corresponding number 5.7 is 5.1.46, as my next good database, if you download the corresponding database-driven, official website a more detailed version of the match, so the download time to remember under the corresponding on it.

The drive to copy the package inside our lib

Then tap and hold to copy the mysql-connector-java-5.1.46.jar, right, build path

Then it points add to build path, so that the later described FIG becomes successful driving added

And then copy the following code to your program inside, you have won. Of course, you need to pay attention to is that you have to be built in the mysql database, such as database name me the following code is nz2001, the name of the database to write your own, you have that into your own. The following code, I want to connect to the database is nz2001, the database user name is root, password is 123456, and then you also need to have their own data table, for example, I want to connect the table below is a person, the code does my job is to insert the user name and password
