Could not resolve placeholder in string value

Question

I am trying to use properties from a  properties file  but it doesn t seem to work   Here is my code    Service  ServiceFTP    Transactional public class ServiceFTPImpl implements ServiceFTP     Value    project ftp adresse    private String adresse    Value    project ftp login    private String compte    Value    project ftp password    private String motDePasse    Value    project ftp root    private String ROOT              This class uses  Value annotations to get the properties  It is also declared as a Spring Service and is linked to my infraContext xml file     lt  xml version  1 0

does make sense  right    But when I try to launch my project  Tomcat throw this exception        ERROR  context ContextLoader initWebApplicationContext    Context initialization failed org

In your configuration you have 2 PropertySourcesPlaceholderConfigurer instances   applicationContext xml   lt bean class  org springframework context support PropertySourcesPlaceholderConfigurer  gt       lt property name  environment  gt           lt bean class  org springframework web context support StandardServletEnvironment   gt       lt  property gt   lt  bean gt    infraContext xml   lt context property-placeholder location  classpath context-core properties   gt    By default a PlaceholderConfigurer is going to fail-fast  so if a placeholder cannot be resolved it will throw an exception  The instance from the applicationContext xml file has no properties and as such will fail on all placeholders   Solution  Remove the one from applicationContext xml as it doesn t add anything it only breaks things

I  m frequently running into this issue on some custom properties that could not be found using IntelliJ IDEA - likely after changing branches  What helpes in my case is  File - gt  Invalidate Caches   Restart  I had the assumption that it is more likely a Gradle caching issue than an IDE issue  but   gradle clean did not help

This Issue occurs if the application is unable to access the some file name properties file Make sure that the properties file is placed under resources folder in spring   Trouble shooting Steps  1  Add the properties file under the resource folder   2  If you don t have a resource folder  Create one by navigating new by Right click on the project new   Source Folder  name it as resource and place your properties file under it   For annotation based Implementation  Add  PropertySource ignoreResourceNotFound   true  value    classpath some file name properties    Add it before using the place holder  Example   Assignment1Controller Java   PropertySource ignoreResourceNotFound   true  value    classpath assignment1 properties    RestController   public class Assignment1Controller         Autowired     Assignment1Services assignment1Services       Value    app title        private String appTitle        RequestMapping value     hello             public String getValues                return appTitle                    assignment1 properties  app title Learning Spring

In my case  I was careless while merging the application yml file  and I ve unnecessary indented my properties to the right   I ve indented it like this   spring      application         name  applicationName                                  myProperties         property1  property1value   While the code expected it to be like this   spring      application          name  applicationName                               myProperties      property1  property1value

You can also try default values  spring-value-annotation  Default values can be provided for properties that might not be defined  In this example the value    some default    will be injected    Value    unknown param some default    private String someDefault    If the same property is defined as a system property and in the properties file  then the system property would be applied

This error appears because the spring project doesn t read the file properties  bootstrap yml or application yml   In order to resolve this  you must add dependency in your pom xml     lt dependency gt           lt groupId gt org springframework cloud lt  groupId gt           lt artifactId gt spring-cloud-context lt  artifactId gt       lt  dependency gt
