Question

我正在尝试运行一个简单的测试来检查属性文件中的值，该文件已保存在我的Maven项目的src / test / resources文件夹中，但JUnit测试失败了。我的测试是拿起文件确定但它没有返回预期的值，因为文件看起来不像它被加载。其他人有类似的问题吗？我的代码/测试如下：

我的应用程序上下文文件：

<bean id="myProps" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="location" value="classpath:test.properties"/>
</bean>

我的代码：

@Resource(name = "myProps") private Properties myProps;
@Value("#{myProps['totalNumberOfChanges']}") private String totalNumberOfChangesStr;
@Value("#{myProps['delayTime']}") private String delayTimeStr;

    public void parseAttributesFromConfigFile() {
        String methodName = "parsePropertyAttributesFromConfigFile";
        try {
            totalNumberOfChanges = Integer.parseInt(totalNumberOfChangesStr);
            delayTime = Integer.parseInt(delayTimeStr);
            numEntriesToIterateThru = (totalNumberOfChanges / delayTime);
        } catch (NumberFormatException nfe) {
            LOGGER.error(methodName, "", "Number Format Exception Occured" + nfe.getMessage());
        }
    }

我的Junit测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:META-INF/spring/Testpu.xml" })
public class ConfigPropertiesTest {
    private final int NUM_ENTRIES_TO_ITERATE_THRU = 100;
    private final int TOTAL_NUMBER_OF_CHANGES = 100000;
    private final int DELAY_TIME = 1000;

    private ConfigProperties configProperties;

    @Before
    public void setUp() throws Exception {
        configProperties = new ConfigProperties();
    }

    @Test
    public final void testParseAttributesFromConfigFileIsCalled() {
        configProperties.parseAttributesFromConfigFile();

        int numEntriesToIterateOver = configProperties.getNumEntriesToIterateThru();
        assertEquals(numEntriesToIterateOver, NUM_ENTRIES_TO_ITERATE_THRU);

        int numberOfChanges = configProperties.getTotalNumberOfChanges();
        assertEquals(numberOfChanges, TOTAL_NUMBER_OF_CHANGES);

        int delayTime = configProperties.getDelayTime();
        assertEquals(delayTime, DELAY_TIME);
    }
}

您正在ConfigProperties方法中创建Before课程。如果希望Spring基于注释填充值，则必须将bean创建为Spring上下文的一部分。如果您的Spring上下文中有ConfigProperties的实例，请使用@Autowired将该实例加载到您的测试中

Junit Test无法加载属性文件
