Question

在spring boot 1.4中，在主类中我有一个导入xml资源的配置类。

@ImportResource("classpath:app-config-c3p0.xml")

在src/test/resources/application.properties我提供了

的属性

datasource.database.master.pool-size=1

但我仍然面临问题，我尝试添加订单，@PropertySource也@TestPropertySource，但都没有。

以下是例外

Caused by: org.springframework.beans.TypeMismatchException: Failed to convert property value of type [java.lang.String] to required type [int] for property 'maxPoolSize'; nested exception is java.lang.NumberFormatException: For input string: "${datasource.database.master.pool-size}"

当没有运行测试时，它工作正常，因为从spring cloud配置服务器读取属性。

以下是测试用例

@WebMvcTest(VCController.class)
@RunWith(SpringRunner.class)
@TestPropertySource("classpath:test.properties")
public class VCControllerTest {

    @MockBean
    private VCGateway vCGateway;

    @Autowired
    private MockMvc mvc;

    @Test
    public void testCreateVoucher() throws Exception {
        int timeout = 10;
        CreateVC createVC = new CreateVC(timeout);
        CreatedVCModel createdVCModel = new CreatedVCModel();

        given(vCGateway.create(createVC)).willReturn(createdVCModel);


        mvc.perform(post("/v1/vc")
                .content(json(createVC))
                .accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isCreated());
    }



}

Answer 1

您是否尝试将class CGeneralContainer bean添加到java配置中以解析@Value注释中的$ {...}表达式。

添加此内部类：

PropertySourcesPlaceholderConfigurer

如果需要将@ContextConfiguration（loader = AnnotationConfigContextLoader.class）添加到@Configuration public static class TestContext{ @Bean public static PropertySourcesPlaceholderConfigurer properties(){ return new PropertySourcesPlaceholderConfigurer(); } }测试类以加载@Configuration类。

Answer 2

当属性未解析时，通常会发生此错误。

在resources下为您的测试属性添加src/test/resources目录，该目录应该有效。

在测试中的xml资源之前读取spring属性源
