movies表description字段GUI文本域显示格式异常求助

Hey there, let's tackle this textarea display problem you're facing!

The root issue here is that your description field doesn't contain explicit newline characters (\n) that textarea components rely on to break content into lines. Your earlier code using replaceAll("\r\n", "...") didn't work because your original text doesn't have \r\n line breaks in the first place—those only exist in the working version you tested.

Here are targeted solutions based on your text pattern:

1. Replace paragraph separators with newlines #

From your example, it looks like paragraphs are separated by a period followed by a space (. ). You can convert these to newline characters so the textarea recognizes line breaks:

// Replace ". " with ".\n" to add a newline after each sentence/paragraph
bean.setDescription(movie.getDescription().replaceAll("\\. ", ".\n"));

Note: We escape the . with \\ because it's a special character in regular expressions.

2. Target specific paragraph starts #

If your text consistently starts new paragraphs with phrases like "The best scene is...", you can directly insert a newline before that phrase:

// Insert a newline before "The best scene" (only if it's not already preceded by a newline)
bean.setDescription(movie.getDescription().replaceAll("(?<!\\n) The best scene", "\nThe best scene"));

The (?<!\\n) part is a negative lookbehind—it ensures we don't add extra newlines if one already exists.

3. Verify your raw text first #

Before implementing replacements, it's a good idea to print out the raw description content to confirm the exact structure:

System.out.println("Raw description: " + movie.getDescription());

This will help you identify the exact separator pattern (e.g., multiple spaces, different punctuation) if the above solutions don't cover your case.

Once you add the proper \n characters, your textarea should render the content with proper line breaks just like your test version did.
