资源既没有源路径也没有目标路径。无法将其添加到捆绑包中
Resource does not have neither a source nor a target path. Impossible to add it to the bundle
我正在尝试使用 kie api 6 读取包含规则的 .xlsx 文件。
但是我得到这个例外
java.lang.RuntimeException: Resource does not have neither a source nor a target path. Impossible to add it to the bundle. P
lease set either the source or target name of the resource before adding it.null

代码如下所示
try {
KieServices ks = KieServices.Factory.get();
KieFileSystem kfs = ks.newKieFileSystem();
kfs.write(ks.getResources().newInputStreamResource(Files.newInputStream(p, StandardOpenOption.READ)));
KieBuilder kb = ks.newKieBuilder(kfs);
if (kb.getResults().getMessages(Level.ERROR).size() != 0) {
logger.lifecycle("Invalid file: {}.", kb.getResults().getMessages());
return false;
}
} catch (Exception e) {
logger.lifecycle("UNEXPECTED ERROR DURING VALIDATION -------------- ", e);
return false;
}
logger.lifecycle("Valid file: {}.", p);
return true;
}
顺便说一句，它在 kfs.write 上失败了。
我还通过在控制台中显示来检查文件路径
Attempt to process rule file: D:\PROJECT_FOLDER\project\src\testInteg\resources\rules\rule.xlsx
这是一条正确的道路。
有什么问题？我正在使用 6.3 Final 版本。
我推荐这个咒语，假设你的String p包含如下所示的路径名：
FileInputStream fis = new FileInputStream( p );
kfs.write( "src/main/resources/rule.xslx",
kieServices.getResources().newInputStreamResource( fis ) );
write到KieFileSystem还有一些其他形式，但我发现这个很容易使用。您可以从 p 派生 rule.xslx，使用 Java 的 API 作为路径名。
