I am using jpos library for transaction management(Spring boot project). I am implementing ISORequestListener as below.
@Component
public class MyRequestListner implements ISORequestListener, Configurable {
protected String var1;
protected String var2;
@Override
public void setConfiguration(Configuration cfg) throws ConfigurationException {
var1 = cfg.get("var1");
var2 = cfg.get("var2");
}
@Override
public boolean process(ISOSource source, ISOMsg m) {
Context ctx = new Context();
ctx.put("ctx1", var1);
ctx.put("ctx2", var2);
return true;
}
}
On running SonarQube (code analyzing tool), I got the error message as:
Annotate global variables with "@Autowired", "@Resource", "@Inject", or "@Value", or don’t use on Spring @Component, @Controller, @Service, and @Repository classes.
Spring @Component, @Controller, @Service, and @Repository classes are singletons by default, meaning only one instance of the class is ever instantiated in the application.
Such a class might have a few static members, such as a logger, but all non-static members should be managed by Spring. That is, they should have one of these annotations: @Resource, @Inject, @Autowired or @Value.
Does this cause any concurrency issue(or thread issue) or internally handled by jpos? What could be the correct implementation if it really causes the problem?
