java - 测试期间未正确读取 MessageSource

Question

我已经检查过大多数类似的问题，但找不到有用的答案。

我正在使用 Maven v3.3.9 通过 JHipster 创建一个 WebApplication。除其他事项外，还发生了 PDF 生成。该网络应用程序是多语言的，并使用

/resources/i18n/..

不同翻译的资源文件。在现场测试中，一切都完美无缺，没有任何问题或错误。

我现在正在尝试创建一个测试，该测试将生成 PDF 并将其与现有 PDF 进行比较，以便继续开发。问题是，无论我使用哪种语言环境进行测试，我都会得到相同的错误:

我不确定错误的原因是什么。由于消息在那里并且在实时测试期间它们完美地工作。

测试代码如下:

    File f1 = new File("../PDFData/testPDF.pdf");
    File f2 = new File("../PDFData/testPDF2.pdf");

    boolean areSame = FileUtils.contentEquals(f1, f2);
    System.out.println("Files were compared...");
    assertTrue(areSame);

}


}

PDFGenerator 创建并保存 testPDF2.pdf 文件。

更新添加:

@PropertySource("classpath:/src/main/resources/i18n/messages_de.properties")

对配置没有做太多。我还从

更改了语言环境

String locale = "de"

到

Locale locale = Locale.GERMAN;

然后我加入了行:

System.out.println(messageSource.getMessage("pdf.klasse", null, this.locale));

直接在测试的开始。我犯了同样的错误。看来问题不在于找到文件，而在于阅读文件。

在你的配置中你需要:

@Bean
public ResourceBundleMessageSource messageSource() {
    ResourceBundleMessageSource source = new ResourceBundleMessageSource();
    source.setBasenames("i18n/messages");
    return source;
}

我的测试是

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class Test1 {

    @Autowired
    private MessageSource messageSource;

    @Test
    public void test1() {
        assertNotNull(messageSource);
        assertEquals("test greg de", messageSource.getMessage("pdf.klasse", null, Locale.GERMANY));
    }
}
