Question

我刚刚发现Spring有一个调试模式，它可以提供有关自动配置的见解。对于服务器，可以通过将--debug作为应用程序参数传递来启用它。

有没有办法为测试启用调试模式（使用SpringJUnit4ClassRunner执行）？

如果自动配置报告正在运行，它应该打印一些输出：

=========================
AUTO-CONFIGURATION REPORT

--debug设置debug属性，然后启用自动配置报告。您可以在测试中使用，例如，在测试类上使用@TestPropertySource：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(Application.class)
@TestPropertySource(properties = "debug=true")
public class YourTests {
    // …
}

如何在测试中启用Spring的自动配置报告？
