Spring : how to replace constructor-arg by annotation? [duplicate]

Answer 1

I think what you are after is this:

@Component
public class MyBean {
    private String xmlFile;
    private String xsdFile;

    @Autowired
    public MyBean(@Value("$MYDIR/myfile.xml") final String xmlFile,
            @Value("$MYDIR/myfile.xsd") final String xsdFile) {
        this.xmlFile = xmlFile;
        this.xsdFile = xsdFile;
    }

    //methods
}

You also might want these files to be configurable via system properties. You can use the @Value annotation to read system properties using the PropertyPlaceholderConfigurer, and the ${} syntax.

To do this, you can use different String values in your @Value annotation:

@Value("${my.xml.file.property}")
@Value("${my.xsd.file.property}")

but you will also need these properties in your system properties:

my.xml.file.property=$MYDIR/myfile.xml
my.xsd.file.property=$MYDIR/myfile.xsd
