如何通过eclipse搜索和替换2行（一起）？ [英] How can one search and replace 2 lines (together) via eclipse?

问题描述

我想通过eclipse搜索以下两行的多个文件：

I would like to search multiple files via eclipse for the following 2 lines:

@Length(max = L_255)
private String description;

并将其替换为这两个：

@Length(max = L_255, message="{validator.description.len}")
private String description;

推荐答案

在Eclipse中，默认情况下，搜索是多行的正在使用正则表达式：

Search are multi-line by default in Eclipse when you are using regex:

(\@Length\(max = L_255)\)([\r\n\s]+private)

我想添加私人字符串描述;

I would like to add "private String description;"

(\@Length\(max = L_255)\)([\r\n\s]+private\s+?String\s+description\s*?;)

替换为：

\1, message="{validator.description.len}")\2

它在由 CTRL - H 。

如 Tika 的 answer ，您可以直接复制在包含文本字段中选择的两行：：这些行将被转换为正则表达式 Eclipse。

As mentioned in Tika's answer, you can directly copy the two lines selected in the "Containing Text" field: those lines will be converted as a regexp for you by Eclipse.
