Company c = new Company(); BeanWrapper bwComp = BeanWrapperImpl(c); // setting the company name... bwComp.setPropertyValue("name", "Some Company Inc."); // ... can also be done like this: PropertyValue v = new PropertyValue("name", "Some Company Inc."); bwComp.setPropertyValue(v);
// ok, let's create the director and tie it to the company: Employee jim = new Employee(); BeanWrapper bwJim = BeanWrapperImpl(jim); bwJim.setPropertyValue("name", "Jim Stravinsky"); bwComp.setPropertyValue("managingDirector", jim);
// retrieving the salary of the managingDirector through the company Float salary = (Float)bwComp.getPropertyValue("managingDirector.salary"); 看起来麻烦了许多，但是这样spring就可以使用统一的方式来管理bean的属性了。
