测试期间未正确读取 MessageSource

Question

我已经检查了大多数类似的问题，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，以便可以继续开发。问题是，无论我使用哪种语言环境进行测试，都会出现相同的错误：

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。

这里是测试代码：

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

}


}

PDFGenerator 创建 testPDF2.pdf 文件并保存。

更新 添加：

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

对配置没有太大作用。我还从

更改了语言环境

String locale = "de"

到

Locale locale = Locale.GERMAN;

然后我加入了：

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

直接在测试开始时。我犯了同样的错误。似乎问题不在于找到文件，而在于读取文件。

Answer 1

在您的配置中，您需要：

@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));
    }
}

Answer 2

我的解决方案。

在测试类中声明 MessageSource 并在测试类中自动装配 DelegatingMessageSource。

private MessageSource messageSource;

@Autowired
private DelegatingMessageSource delegatingMessageSource;

如下图所示创建设置

@Before
public void setUp() {
  messageSource = Mockito.mock(MessageSource.class);
  when(messageSource.getMessage(anyString(), any(Object[].class),any(Locale.class))).thenReturn("");
  delegatingMessageSource.setParentMessageSource(messageSource);
}

它应该可以正常工作。
