Java calls Google Analytics API for website statistics

First, apply for a Google account and Google Analytics service, and put the statistics code into the website you want to count for a period of time to ensure that your Google Analytics has data.

In Google Analytics, go to your configuration file modification page and write down the red-marked number. This is your "Table ID ".

The following code is a piece of code that I modified and commented out according to the official Google Documents to collect statistics on access traffic and other information.

Finally, call the myTest () method of this class in any way (main () or servlet.

Note:

1. Add "ga:" before the number of Table ID, for example, ga: 47778978
2. The dimensions and metrics to be obtained must be set in query. setDimensions () and query. setMetrics (). See the preceding example.
3. For more information about dimensions and metrics, see the official Google documentation: http://code.google.com/intl/zh-CN/apis/analytics/docs/gdata/gdataReferenceDimensionsMetrics.html.
