Question

I have two constructors:

ctor(String a, String b, char[] c)

ctor(String a, String b, File c)

Now, she I do sth like

<bean id="myBean"  class="myClass">
    <constructor-arg value="string1" />
    <constructor-arg value="string2" />
    <constructor-arg value="toCharArray" />

this is resolved using File constructor by spring… any ideas how to stop this?

Answer 1

You can resolve this in adding the type information to the constructor-arg element using the type attribute. See the chapter 4.4.1.1 Constructor-based dependency injection in the Spring documentation for further details.

<bean id="myBean" class="myClass">
  <constructor-arg type="java.lang.String" value="string1" />
  <constructor-arg type="java.lang.String" value="string2" />
  <constructor-arg type="char[]" value="toCharArray" />
</bean>
