Question

背景：我想自动针对架构验证XML文件。为此，我在XMLValidator创建了一个maven项目和一个src/main/java - 类。

要运行测试，我在XMLValidatorTest中创建了src/test/java。我的想法是将我要验证的XML和XSD文件放入src/test/resources文件夹，并按文件名“抓取”它们。但是当我运行mvn test时，找不到文件。

我的测试班：

public class XMLValidatorTest {

  XMLValidator xmlvalidator;

  // XSD is in src\test\resources\XSD\myXSD.xsd
  String xsdFileNameWithPath = "XSD\\myXSD.xsd";

  @Before
  public void setup() {
    xmlvalidator = new XMLValidator();
  }

  @Test
  public void testValidate() {

    // XML is in src\test\resources\XML\test001.xml
    String xmlFileNameWithPath = "XML\\test001.xml";


    assertTrue(xmlvalidator.validate(xmlFileNameWithPath, xsdFileNameWithPath));
  } 
}

当我运行mvn test时，我收到了一个未找到文件的例外情况，例如java.io.FileNotFoundException: D:\workspace_eclipse\XSDTester\XSD\myXSD.xsd - 它在资源文件夹中是正确的。

我尝试通过<testresources> - 代码复制文件，从Maven (surefire): copy test resources from src/test/java开始尝试解决方案，但它没有效果。

<build>
  <testResources>
    <testResource>
      <directory>${project.basedir}/src/test/resources</directory>
    </testResource>
  </testResources>
</build>

有任何建议吗？

P.S。在我的XMLValidator中，我尝试通过以下方式使用给定的文件：

Source xmlFile = new StreamSource(new File(xmlFileNameWithPath));
Source xsdFile = new StreamSource(new File(xsdFileNameWithPath));

修改

我再次尝试使用this.getClass().getResourceAsStream()来实施Michele Sacchetti建议。

因此，为了检索XML文件，我试试这个

validate (String xmlFileNameWithPath, String xsdFileNameWithPath) {

  Source xmlFile;
  try {
    // give systemid according to: https://stackoverflow.com/questions/10997453/java-xml-validation-does-not-work-when-schema-comes-from-classpath
    xmlFile = new StreamSource(getClass().getResourceAsStream(xmlFileNameWithPath), getClass().getResource(xsdFileNameWithPath).toString());
  } catch (Exception e) {
    System.out.println("XML is null");
    return false;   
  } 

  // ...  further steps, trying to get the XSD and validate them
}

并通过（正如Michele Sacchetti所说的省略src\test\resources）

来调用该函数

// XSD is in src\test\resources\XSD\myXSD.xsd
String xsdFileNameWithPath = "XSD\\myXSD.xsd";

// XML is in src\test\resources\XML\test001.xml
String xmlFileNameWithPath = "XML\\test001.xml";

validate(xmlFileNameWithPath, xsdFileNameWithPath);

但我总是得到一个NPE，然后尝试获取该文件的StreamSource。

不要尝试通过文件名访问文件，而是使用this.getClass().getResourceAsStream()方法通过CLASSPATH访问它们（您必须省略开始/src/test/resources）

样本bleow文件中的

位于

下

src/test/resources/test/test.properties

的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

测试源

package test;

import java.io.IOException;
import java.net.URISyntaxException;
import org.junit.Test;

public class ReadFileTest {


    @Test
    public void readTest() throws IOException, URISyntaxException{
        System.out.println(ReadFileTest.class.getResource("test.properties").toURI());
    }

}

mvn clean test output

请注意，返回路径正确地进入目标文件夹而不是src中

如何在测试期间使用test / resources文件夹中的文件进行验证？
