英文:
Cannot read value using @Value() in application.yml
问题
我只是尝试设置环境变量的默认值，如下所示：
app:
security:
testUser: ${TEST_USER:spring}
testPassword: ${TEST_PASSWORD:secret}
我尝试读取这些值：
@Value("${TEST_USER}")
private String testUser;
@Value("${TEST_PASSWORD}")
private String testPassword;
然而，在运行应用程序时，它没有读取默认值并抛出错误：> 无法解析占位符 'TEST_USER' 在值 "${TEST_USER}"我也尝试过：
testUser: ${TEST_USER:#{spring}}
但仍然出现相同的错误。那么，如何解决这个问题？
英文:
I am simply trying to set default values for environment variables as shown below:
app:security:testUser: ${TEST_USER:spring}testPassword: ${TEST_PASSWORD:secret}
I am trying to read this values:
@Value("${TEST_USER}")private String testUser;@Value("${TEST_PASSWORD}")private String testPassword;
However, when running app, it does not read the default values and throws error:
> Could not resolve placeholder 'TEST_USER' in value "${TEST_USER}"
I also tried as:
testUser: ${TEST_USER:#{spring}}
But still the same error. So, how to solve this?

你需要说 @Value("${app.security.testUser}")。它将从TEST_USER环境变量中获取值，如果不存在这样的环境变量，则默认为 spring。
英文:
You need to say @Value("${app.security.testUser}"). It will take the value from TEST_USER environment variable or default to spring if such an environment variable does not exist
