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
