SpringBoot向resources下写文件的两种方式
作者:zhou_zhao_xu
这篇文章给大家分享了两种SpringBoot向resources下写文件的方式,每种方式都有详细的代码示例,对我们的学习或工作有一定的帮助,需要的朋友可以参考下
方式一:
import java.io.File; import java.io.FileWriter; import java.io.IOException; public class WriterFileUtils { private static final String prefix = "classpath:"; public static void writeFile(String directory, String fileName, String content){ directory = prefix + directory; try { File dir = new File(directory); if (!dir.exists()){ dir.mkdir(); } String filePath = directory + fileName; File file = new File(filePath); if(!file.exists()){ file.createNewFile(); } FileWriter fw = new FileWriter(filePath); fw.write(content); fw.close(); } catch (IOException e) { throw new RuntimeException(e); } } }
方式二:
import java.io.File; import java.io.FileWriter; import java.io.IOException; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.core.io.Resource; import org.springframework.core.io.ResourceLoader; /** * @author zzx * @version : WriterFileUtils.java, v 0.1 2023年08月22日 11:24 zzx Exp $ */ public class WriterFileUtils { public static final WriterFileUtils INSTANCE = new WriterFileUtils(); @Autowired private ResourceLoader resourceLoader; private static final String prefix = "classpath:"; public void writeFile(String directory, String fileName, String content){ try { directory = prefix + directory; Resource dirResource = resourceLoader.getResource(directory); File dir = dirResource.getFile(); if (!dir.exists()){ dir.mkdir(); } String filePath = directory + fileName; Resource fileResource = resourceLoader.getResource(filePath); File file = fileResource.getFile(); if(!file.exists()){ file.createNewFile(); } FileWriter fw = new FileWriter(filePath); fw.write(content); fw.close(); } catch (IOException e) { throw new RuntimeException(e); } } }
