Converting Boolean bean creation to boolean using Spring

Question

So, I have something like this in one of my java files:

@Resource(name = "initializationCache")
Boolean initializationCache;

In a config file, I have this:

<bean id="initializationCache" class="java.lang.Boolean">
    <constructor-arg value="${initialization.cache}" />
</bean>

How would I go about making this work using a primitive boolean?

Answer 1

In Spring 3 you can do it without intermediate bean using @Value:

@Value("${initialization.cache}")
boolean initializationCache;

Answer 2

I guess one way to go would be to declare a setter of Boolean type and let it assign the value to a field of boolean type, i.e.

boolean initializationCache;

@Resource(name = "initializationCache")
public void setInitializationCache(Boolean b) {
  this.initializationCache = b;
}

I haven't tested it though.
