在类路径中找不到 xslt 文件

Question

尝试使用包含规则的 XSLT 文件将一个 xml 转换为另一个 xml

使用 xslt 存在于 src/main/resources/test.xslt 中从输入文件夹中读取转换，并将输出存储在 F 驱动器的输出文件夹中

 @Component
  public class MyRoute extends RouteBuilder {
    @Override
    public void configure() throws Exception {
        from("file:F:\\input")
        .to("xslt:file:///springApp/test.xslt")
        .to("file:F:\\output");
        
}

pom.xml

错误：-

尝试改变路径 -

@Component
public class MyRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("file:F:\\input")
        .to("xslt:springApp/src/main/resources/test.xslt")
        .to("file:C:\\output");

}

遇到错误

Answer 1

您只需要类路径中的相对路径，这将是：

to("xslt:test.xslt")
