Spring @Value Set Default values

The role of @Value Needless to say, we all know. Read Profile injection property values in annotation mode

　　

/**
* MQ Address
*/
@Value ("${namesrvaddr}")
Private String namesrvaddr;

Above is a marked @Value annotation

If the configuration file is not set up namesrvaddr Spring will tell you the error when it starts.

Setting default values is simple

@Value ("${namesrvaddr:192.168.0.1}")

Private String namesrvaddr;

Benefits of setting default values

Reduces the data that configuration files need to be configured and simplifies

Ps:

Why write a separate post?

Accidental Baidu over this problem, then the answer is almost no, or is not simple enough to write clear.
