You can use HTMLin JLabels. To use it, your text has to start with <html>.
您可以HTML在JLabels. 要使用它，您的文本必须以<html>.
Set your text to "<html>This is<br>a multi-line string"and it should work.
将您的文本设置为"<html>This is<br>a multi-line string"，它应该可以工作。
See Swing Tutorial: JLabeland Multiline label (HTML)for more information.

JLabel can accept html code. Maybe you can try to use the <br>tag.
JLabel 可以接受 html 代码。也许你可以尝试使用<br>标签。
Example:
例子：
JLabel myLabel = new JLabel();
myLabel.setText("<html> This is a <br> multi-line string </html>");

The direct procedure of writing a multi-line text in a jlabel is:
在 jlabel 中写入多行文本的直接过程是：
JLabel label = new JLabel("<html>First Line<br>Second Line</html>");

Another easy way (but changes the text style a bit) is to use a <pre></pre>html block.
另一种简单的方法（但稍微改变了文本样式）是使用<pre></pre>html 块。
This will persist any formatting the user entered if the string you are using came from a user input box.
如果您使用的字符串来自用户输入框，这将保留用户输入的任何格式。
Example:
例子：
JLabel label = new JLabel("<html><pre>First Line\nSecond Line</pre></html>");

The problem with using html in JLabelor any Swing component is that you then have to style it as html, not with the usual setFont, setForeground, etc. If you're ok with that, fine.
在使用HTML的问题JLabel或任何Swing组件是，你再要的风格为HTML，不跟平时setFont，setForeground等等。如果你真行与精细。
Otherwise you can use something like MultilineLabelfrom JIDE, which extends JTextArea. It's part of their open source Commom Layer.
否则，您可以使用JIDE 中的MultilineLabel 之类的东西，它扩展了JTextArea. 这是他们开源Commom Layer的一部分。

public class JMultilineLabel extends JTextArea{
private static final long serialVersionUID = 1L;
public JMultilineLabel(String text){
super(text);
setEditable(false);
setCursor(null);
setOpaque(false);
setFocusable(false);
setFont(UIManager.getFont("Label.font"));
setWrapStyleWord(true);
setLineWrap(true);
//According to Mariana this might improve it
setBorder(new EmptyBorder(5, 5, 5, 5));
setAlignmentY(JLabel.CENTER_ALIGNMENT);
}
}
It totally looks the same for me, but its ugly
对我来说完全一样，但它丑陋
