Spring: Configuring Bean with a two argument setter

由 此生再无相见时 提交于 2019-12-12 08:47:17
问题 I would like to configure a HttpParams using spring setter injection but HttpParams has a two argument setter ( setParameter(String name, Object object) ). Is anyone aware of a way to configure this in spring? The closest I can think of is like you would do a List, Set, or Property configuration: http://www.mkyong.com/spring/spring-collections-list-set-map-and-properties-example/ Thanks! 回答1: Strictly speaking: A setter with two parameters is not a setter. It violates the JavaBeans convention

How to use new BeanInfo Annotations in Java 9

由 喜夏-厌秋 提交于 2019-12-12 04:32:56
问题 JEP 256: BeanInfo Annotations provides for JavaBean and BeanProperty annotations. While there is not much documentation, I have been hoping this would allow us to use annotations to designate fields on a class as being JavaBean-style properties without having to create boilerplate getter/setter accessor/mutator methods. So this: public class Person { private String name ; public String getName( ) { return this.name ; } public void setName( String nameArg ) { this.name = nameArg ; } } …would

One of the property is an object which properties are changed every view seconds. I don't want to create for this particular object new instance every time it is being updated (for the propertychangelistener to notice the change), so I wrote my own equals method where I ommit the comparation to itself. @Override public boolean equals(Object item) {
