Spring application.properties 文件中的布尔值? [英] boolean values in Spring application.properties file?

问题描述

Spring 配置文件中是否可以有布尔值?

Is it possible to have boolean values in Spring configuration file?

我在我的 bean 中写了以下字段:

I wrote the following field in my bean:

@Value("${pdk.populatedemo}")
private boolean populateDemo;

但是如果导致以下异常:

but if causes the following exception:

Could not autowire field: private boolean com.inthemoon.pdk.data.DatabaseService.populateDemo; nested exception is org.springframework.beans.TypeMismatchException: 
Failed to convert value of type [java.lang.String] to required type [boolean]; nested exception is java.lang.IllegalArgumentException: 
Invalid boolean value [1;]

这里我试过了

pdk.populatedemo=1;

在 application.properties 中.我也试过 =true 和其他一些.

in application.properties. I also tried =true and some others.

推荐答案

布尔类型的正确值是

pdk.populatedemo=true

1 不是布尔字段的有效值，您不得在属性文件中将分号用于布尔值(正如您在错误消息中清楚地看到的那样).

1 is not a valid value for a boolean field and you must not use semicolons in your property file for a boolean value (as you clearly can see in the error message).
