Question

将spring从2.0.8升级到2.1.2（使用JDK 8）时，应用程序启动并运行正常，但由于__urlencode()而导致测试失败。

我正在使用某些测试可以扩展的抽象类。

java.lang.IllegalStateException: Failed to load ApplicationContext

EnvironmentalProperties类是用于类型安全配置属性（Doc）的类

在可以进行升级之前，提供了一类EnvironmentalProperty，但是现在我得到了

@SpringBootTest
@RunWith(SpringRunner.class)
public abstract class AbstractTestkonfiguration {

  @TestConfiguration
  static class TestEnvironmentConfiguration {
    @Component
    @PropertySource(value = "classpath:my-test.properties")
    @ConfigurationProperties(prefix = "my")
    public static class MyTestProperties extends EnvironmentalProperties {
    }
  }

}

这是否与嵌套配置类检测（Upgrading to Spring Framework 5.x）中的更改有关？如果是这样，如何配置仅用于测试的EnvironmentalProperties Bean？

更新：即使按以下方式使用也不起作用（结果相同）。

[...]

您需要进行一些更改。

您尚未通过@EnableConfigurationProperties启用配置属性
属性源需要在测试类中注入
删除@Component批注

这是一个可行的示例；

src/test/resources/my-test.properties

my.server.name=foo
my.server=test

和

src/main/resources/application.properties

my.name=production

生产配置。

@ConfigurationProperties(prefix = "my")
@PropertySource(value = "classpath:application.properties")
public class EnvironmentalProperties {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(final String name) {
        this.name = name;
    }
}

@SpringBootTest
@TestPropertySource(value = {"classpath:my-test.properties", "classpath:application.properties"})
@RunWith(SpringRunner.class)
public class AbstractTestkonfiguration {
    @Autowired
    private MyTestProperties myTestProperties;


    @TestConfiguration
    @EnableConfigurationProperties(MyTestProperties.class)
    public static class TestEnvironmentConfiguration {
        @ConfigurationProperties(prefix = "my")
        public static class MyTestProperties  extends EnvironmentalProperties {
            private String server;

            public String getServer() {
                return server;
            }

            public void setServer(final String server) {
                this.server = server;
            }
        }
    }

    @Test
    public void check_configuration () {
        Assert.assertEquals(myTestProperties.getServer(), "test");
        Assert.assertEquals(myTestProperties.getName(), "production");
    }

这适用于Java 11和spring-boot 2.1.2.RELEASE。请注意，这仅是示例。您将不得不正确地使其适应您的项目。
