java - How to work with annotation based properties in Spring -

i use 'someotherproperty' value inside someifacedaoimpl

but when debug, it's null, inside bean definition , inside bean constructor well. tried use @value annotation inside class not work either.

however, database values works fine , available inside jdbctemplate bean.

my properties file contains

database.url=jdbc:mysql://localhost:3306/databasename database.username=root database.password=password someotherproperty=helloworld 

my configuration class:

@configuration @profile("production") @componentscan(basepackages = { "com.packagename" }) @propertysource({"classpath:packagename.properties"}) public class contextconfig {     @value("${database.url}")     private string url;     @value("${database.username}")     private string username;     @value("${database.password}")     private string password;       @value("${someotherproperty}")     private string someotherproperty;      @bean(name = "jdbctemplate")     public jdbctemplate jdbctemplate() {         jdbctemplate jdbctemplate = new jdbctemplate();         basicdatasource datasource = new basicdatasource();         datasource.seturl(stringutil.appendobjects(url, "?",     "useserverprepstmts=false&rewritebatchedstatements=true"));         datasource.setdriverclassname("com.mysql.jdbc.driver");         datasource.setusername(username);         datasource.setpassword(password);         jdbctemplate.setdatasource(datasource);         return jdbctemplate;     }      @bean     public isomeifacedao isomeifacedao() {         return new isomeifacedaoimpl(); //<---- have someotherproperty value here or inside constructor     }  } 

thank you.

you should able use 'someotherproperty' directly in bean method there's no misconfiguration in property file. better approach avoid having multiple fields annotated @value using environment abstraction

@configuration @profile("production") @componentscan(basepackages = { "com.packagename" }) @propertysource({"classpath:packagename.properties"}) public class contextconfig {    @autowired   private environment env;    @bean   public isomeifacedao isomeifacedao() {     return new isomeifacedaoimpl(env.getrequiredproperty("someotherproperty"));   } }
