| 147 | + <title>Support for injection against non-standard JavaBeans setters</title> |
| 148 | + <para>Prior to Spring 3.1, in order to inject against a property method it had to |
| 149 | + conform strictly to JavaBeans property signature rules, namely that any 'setter' |
| 150 | + method must be void-returning. It is now possible in Spring XML to specify |
| 151 | + setter methods that return any object type. This is useful when considering |
| 152 | + designing APIs for method-chaining, where setter methods return a reference to |
| 153 | + 'this'.</para> |
