java - Spring: use properties read from a file -

i'm new spring framework , i'm having problems trying read , use properties file.

to summarize, want define class stores properties read, second class uses properties , third class uses results.

the class stores properties is:

@configuration public class propertyclass {     @value("${propertyname")     private integer propertyname;      @bean(name = "propertyname")     public integer getpropertyname() {         return propertyname;     } } 

the class reads , uses properties:

@component public class propertyreader {     private integer myproperty;      @autowire     @qualifier("propertyname")     public void setmyproperty(         integer myproperty) {         this.myproperty = myproperty;     }        public integer getvalue() {         //do myproperty         return result;     } } 

and class uses propertyreader:

public class utilizer {     private propertyreader getpropertyreader() {         applicationcontext context = new annotationconfigapplicationcontext(propertyreader.class);         propertyreader reader = (bakerstorageclassconfighelper)context.getbean("propertyreader");         return reader;     } } 

i've registered classes beans in application-config.xml file:

<bean class="property.class.package.propertyclass" depends-on="environment" /> <bean class="reader.class.package.propertyreader" /> 

and have environment.xml file "environment" bean defined location rules find property files.

now happens in class "utilizer" when try "applicationcontext" object exception thrown:

org.springframework.beans.factory.beancreationexception: error creating bean name 'propertyreader':  injection of autowired dependencies failed; nested exception org.springframework.beans.factory.beancreationexception:  not autowire method: public void reader.class.package.propertyreader.setmyproperty(java.lang.integer);  nested exception org.springframework.beans.factory.nosuchbeandefinitionexception: no qualifying bean of type [java.lang.integer]  found dependency: expected @ least 1 bean qualifies autowire candidate dependency. dependency annotations: {} 

i've tried change annotation of propertyreader class @repository or @service , tried add @componentscan propertyclass package specified none of worked me..

could give me advices?
thank you!

i not quite why need declare propertyname integer. if need properties file, can define propertiesfactorybean , autowire other beans like.

let's have myvalues.properties file containing values:

key1=value1 key2=value2  

define bean:

@bean(name = "myproperties") public propertiesfactorybean detailqueriesfactorybean() {     propertiesfactorybean pfb = new propertiesfactorybean();     pfb.setlocation(new classpathresource("com/xxx/myvalues.properties"));     return pfb; } 

now wherever need it, do:

@autowired @qualifier("myproperties") private properties myvaluescontainer;  public void mymethod(){   //this "value1"   string value1 = myvaluescontainer.getproperty("key1"); } 

hope works you.

if in application context, can use @value inject value directly in propertyreader , add getter/setter them. no need propertyclass, right?

or can add @postconstruct method propertyreader. inside method, can retrieve values need existing context.

@postcontstruct public void extractvalues(){     //retrieve value context , assign whichever var. }
