笔记：将Mybatis自动生成的sql查询代码转换为可直接在java中执行

笔记：将Mybatis自动生成的sql查询代码转换为可直接在java中执行

之前接了个特别的任务，要把项目里所有的sql查询要改成在代码中执行。。。。为了避免下次又遇到类似的特殊任务，先记下来。

方法也很简单：把mybatis中的代码复制到文件中，读取然后格式化即可

public class RedText {

	public static StringBuffer red(String filePath) {
		StringBuffer fileinfo = new StringBuffer();
		try {
			InputStreamReader inputStreamReader = new InputStreamReader(new FileInputStream(filePath), "utf-8");
			BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
			String lineText = null;
			int count = 0;
			while ((lineText = bufferedReader.readLine()) != null) {
				String[] line = lineText.split(" AS");
				for (int i = 0; i < line.length; i++) {
					StringBuffer linbf = new StringBuffer();
					if (i == 0) {
						linbf.append(line[i]);
						if (count == 0) {
							linbf.insert(0, """);
						} else {
							linbf.insert(0, "",");
						}
						linbf.insert(linbf.length(), " AS"+ ");
					} else {
						linbf.append(line[i].replace(",", "").replace("\", ""));
						linbf.insert(1, ""\");
						linbf.insert(linbf.length()-1, "\");
						linbf.insert(linbf.length(), ""+");
					}
					count += 1;
					fileinfo.append(linbf);
				}
			}
			bufferedReader.close();
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return fileinfo;
	}
}
