我的src / main / resources目录下有我的XML文件。我的春天代码看起来像
import java.io.IOException;
import java.util.concurrent.atomic.AtomicLong;
import com.google.common.base.Charsets;
import com.google.common.io.Files;
import org.springframework.core.io.ClassPathResource;
import org.springframework.integration.xml.transformer.XsltPayloadTransformer;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class BdeApplicationController {
@GetMapping("/ping")
@ResponseBody
public String ping(@RequestParam(name="name", required=false, defaultValue="Stranger") String name) {
return myFlow();
}
private String myFlow() {
XsltPayloadTransformer transformer = getXsltTransformer();
return transformer.transform(buildMessage(getXMLFileString())).toString();
}
private String getXMLFileString() {
try {
return Files.toString(new ClassPathResource("XML1.xml").getFile(), Charsets.UTF_8);
} catch (IOException e) {
e.printStackTrace();
}
return "";
}
private XsltPayloadTransformer getXsltTransformer() {
return new XsltPayloadTransformer(new ClassPathResource("XSLT1.xsl"));
}
protected Message<?> buildMessage(Object payload) {
return MessageBuilder.withPayload(payload).build();
}
}
运行此代码后,我收到以下异常: -
java.io.FileNotFoundException:类路径资源[XML1.xml]无法解析为绝对文件路径,因为它不驻留在文件系统中:jar:file:/ Users / user / Documents / project / target / bde -0.0.1-SNAPSHOT.jar!/ BOOT-INF /类!/XML1.xml
你能否建议我如何解决这个问题?
答案 0 :(得分:4)
当你使用resource.getFile()时,你在文件系统中查找文件,这就是为什么当你以jar形式运行时它不起作用。
尝试使用InputStream
String data = "";
ClassPathResource resource = new ClassPathResource("/XML1.xml");
try {
byte[] dataArr = FileCopyUtils.copyToByteArray(resource.getInputStream());
data = new String(dataArr, StandardCharsets.UTF_8);
} catch (IOException e) {
// do whatever
}
