This question already has answers here :
Base on this you can try:
@Value("#{new Boolean('${app.settings.value1}')}")
private Boolean value1;
But the real problem is here:
exception is java.lang.IllegalArgumentException: Invalid boolean value [**${app.settings.value1}**]. It pass not the value but the label, that cannot be parsed as boolean.
YAML not parsed correctly when using @PropertySource � Issue , YAML not parsed correctly when using @PropertySource #15400 did not work either as Spring (Boot?) does not parse the configuration correctly. foo with an empty string and a property bar with the string value of qux . @Value. Configuration is an important topic of every application which has more than a couple of hundred lines of code. In case you are using Spring, you would typically use Spring’s @Value annotation to load values from a Java properties file.
Also it can be primitive:
@Value("${app.settings.value1:false}")
private boolean value1;
Spring - ${} is not working in @Value, But the property placeholder ${} is unable to resolve in @Value , if print out the driver variable, it will display string ${db.driver} directly, instead� @Configuration @PropertySource("classpath:db.properties") public class AppConfig { @Value("${db.driver}") private String driver; But the property placeholder ${} is unable to resolve in @Value, if print out the driver variable, it will display string ${db.driver} directly, instead of “oracle.jdbc.driver.OracleDriver”.
You can try the following ways:
//If you need a Boolean object
@Value("#{new Boolean('${app.settings.value1}")
private Boolean value1;
OR
//If you need a primitive boolean
@Value("${app.settings.value1:true}")
private boolean value1;
Please check boolean values in Spring application.properties file?
The @Value Annotation in Spring, Value is a Java annotation used at the field or method/constructor level. The main focus of this article is to help you understand how Spring's @Value annotation naming conventions - Spring searches for us and assigns the correct value. We also need to be aware that not everything that looks simple is also very good� Spring @Value – Spring Environment Property @Value("${APP_NAME_NOT_FOUND}") private String defaultAppName; If the key is not found in the spring environment properties, then the property value will be ${APP_NAME_NOT_FOUND}. We can assign a default value that will get assigned if the key is missing from spring environment properties.
Please try this code:
@Value("${app.settings.value1}")
private Boolean value1;
Spring Boot Features, If the SpringApplication defaults are not to your taste, you can instead create a If the application context has started successfully, Spring Boot assumes that the Property values can be injected directly into your beans by using the @Value the brackets need to be surrounded by quotes for the keys to be parsed properly. @PropertySource(value=”file:W:\myHome\Env\conf, W:\myHome\Env\conf\spring) I am only providing the path & under that path are various properties file which I would like to load. Also in application.properties I did this spring.config.location=file:W:\myHome\Env\conf, W:\myHome\Env\conf\spring But it is not working. Could you please suggest
8. Spring Expression Language (SpEL), Most Spring users will not need to deal with this infrastructure and will instead The interface ExpressionParser is responsible for parsing an expression string. In the last line, the value of the string variable name will be set to "Nikola Tesla". SpEL and the conversion service will // correctly recognize that it needs to be a � Spring's @Value annotation provides a convenient way to inject property values into components. It's also quite useful to provide sensible defaults for cases where a property may not be present . That's what we're going to be focusing on in this article – how to specify a default value for the @Value Spring annotation.
Properties with Spring and Spring Boot, Tutorial for how to work with properties files and property values in Spring. < property-placeholder> will not expose the properties to the Spring Environment Working with the PropertyPlaceholderConfigurer gives us full control over the Hey Anup – so let me see if I understand your usecase correctly. This tutorial shows you the way to inject Properties from Properties File using @Value Annotation with Java Configuration and @PropertySource.. You will also know how to use SourcesPlaceHolder and ConversionService for specific cases including: List/Arrays, special types (DateTime, Pattern), when a value that should be treated as null or a placeholder fails to resolve.
Spring Expression Language Guide, This article explores Spring Expression Language (SpEL), In the example above, assume someProperty has value 2, so resulting expression would be The matches operator can be used to check whether or not a string At times, we may want to parse expressions outside the context of configuration. Injecting a Property or a System Property using spring @Value annotation. The spring @Value annotation can be placed on fields, methods and method/constructor parameters to specify a default value. In this example we are first loading a property from the application.properties file. Then we also load a system property both using the spring
Comments can you format the yaml a little better For non String values , you can try @Value("#{new Boolean('${app.settings.value1}") @Value("#{new Boolean('${app.settings.value1:true}") OR @Value("'${app.settings.value1}") private boolean value1 ; //Note the use of primitive the link which you have shared trying to convert 1 to boolean, where as in my case it is not reading the value and It is trying to convert whatever present inside @Value("") . As a note, @ConfigurationProperties classes are almost always preferable to @Value in Boot.
