Java implements the function of exporting the object array through Excel

1、 Import the relevant jar packages. POM dependencies are as follows:

2、 Start code

1. If the export function is used more, it can be made into a tool class to transform the code posted below

2. After the "tool class" is written, we will start to use it. From the function parameters above, we need to pass two objects. One is the output stream OutputStream, which wants excel to the browser through the stream,

The other is the object array we need to export. Well, don't explain too much. Look at the code. (the following method is written in the action layer and can be downloaded through struts.xml configuration access)

3、 Development (detailed tool development)

If you think what is written above is too simple, you can continue to read it. I sorted it out a "universal" tool class for your reference.

This part is rough, but the implementation is more detailed. It is for reference only. You can slightly transform it into your own unique utils.

The above is the whole content of this article. I hope the content of this article can bring some help to your study or work. At the same time, I also hope to support a lot of programming tips!
