Introspector(内省)

class TestReflect { @Test fun testReflect() { //获取字节码对象 val clazz = Product::class.java //创建实体对象 val product = clazz.newInstance() //获取声明的字段 val fields = clazz.declaredFields /* val writeMethodName = "set${it.name.substring(0, 1).toUpperCase()}${it.name.substring(1)}" println(writeMethodName) val writeMethod = clazz.getDeclaredMethod(writeMethodName, it.type) writeMethod.invoke(product,13)*/ //通过Introspector获取javaBean信息 val beanInfo = Introspector.getBeanInfo(clazz) //通过beanInfo获取到所有的属性描述,遍历获取它们的set方法 beanInfo.propertyDescriptors.forEach { println(it.writeMethod) } }
