java - How to inject Spring Bean for factory method requiring MyClass.class parameter -

-

i'm trying inject java.util.prefs.preferences bean in master controller. controller looks like:

@controller class mycontroller {     @autowired     private preferences preferences; }

the application-context.xml file creates bean java.util.prefs.preferences. uses factory method have following entry creating bean:

<bean id="preferences" class="java.util.prefs.preferences" factory-method="usernodeforpackage" />

preferences.usernodeforpackage(param) takes parameter class related preference. in case spring needs create bean performing call: 

preferences.usernodeforpackage(mycontroller.class);

how can class passed in spring bean instantiated factory method? thanks

environment information:

java 7 spring 3.1

you can specify constructor-arg element

<bean id="preferences" class="java.util.prefs.preferences" factory-method="usernodeforpackage">     <constructor-arg type="java.lang.class" value="com.path.mycontroller" /> </bean>

this explained in official documentation here, section 5.4.1.

arguments static factory method supplied via elements, same if constructor had been used. type of class being returned factory method not have of same type class contains static factory method, although in example is. instance (non-static) factory method used in identical fashion (aside use of factory-bean attribute instead of class attribute), details not discussed here.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
