Question

想知道是否有任何方法可以重用某些Java反射API / SOAP / Web服务内部函数或外部API来实现：

拥有一个对象列表，通过线路获取方法
Via config包含与这些对象相对应的类列表
一个pojo，其属性必须填充1

是否有通用的+几行方式？

实施例

void process(Object pojoToFill, Class[] classesOfSetters, Objects[] values) {
         //what to do here to fill up pojoToFill with values using classesOfSetters, in a generic way?
}

void sample() {
    Object []objects;// filled with values that are needed by Person class, sent over the wire, setters
    Class []propertyClasses = new Class[String.class, Address.class]//from config
    Person person = new Person();
    process(person, propertyClasses, objects);

}


public class Person {
    private String name;
    private Address address;// etc
    // getters and setters

}

class Address {
    private String line1;// other properties and getters and setters
}

Answer 1

这应该可以通过java反射API实现。

为每个setter类

传递setter方法名称

void process(Object pojoToFill, Class[] classesOfSetters, String[] setterMethods, Objects[] values) {
 for (int i=0; i < classesOfSetters.length; i++){
Method methodToSetValue = classesOfsetter.getMethod(setterMethods[i]);
methodToSetValue.invoke (pojoToFill, Objects[i]);
}        
}

正在使用javabeans（getter / setter方法）;您也可以使用Bean introspection in Java API。

自动铸造和填充POJO
