我建议将完整的AspectJ与
set()切入点结合使用，以获得有效的解决方案。但是，如果您不介意使用缓慢而丑陋的解决方案来进行反射，那么您也可以执行以下操作：
package de.scrum_master.app;public class Person { private int id; private String firstName; private String lastName; public Person(int id, String firstName, String lastName) { this.id = id; this.firstName = firstName; this.lastName = lastName; } public int getId() { return id; } public String getFirstName() { return firstName; } public String getLastName() { return lastName; } public void setId(int id) { this.id = id; } public void setFirstName(String firstName) { this.firstName = firstName; } public void setLastName(String lastName) { this.lastName = lastName; } @Override public String toString() { return "Person [" + id + ", " + firstName + " " + lastName + "]"; } public static void main(String[] args) { Person albert = new Person(1, "Albert", "Camus"); Person audrey = new Person(2, "Audrey", "Hepburn"); System.out.println(albert); System.out.println(audrey); System.out.println(); albert.setId(8); albert.setLastName("Einstein"); audrey.setId(9); audrey.setLastName("Tautou"); System.out.println(); System.out.println(albert); System.out.println(audrey); }}package de.scrum_master.aspect;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.SoftException;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;@Aspectpublic class SetterInterceptor { @Before("execution(* set*(*)) && target(instance) && args(newValue)") public void beforeSetterCalled(JoinPoint thisJoinPoint, Object instance, Object newValue) { String methodName = thisJoinPoint.getSignature().getName(); try { System.out.println( methodName.substring(3) + ": " + instance .getClass() .getMethod(methodName.replaceFirst("set", "get")) .invoke(instance) + " -> " + newValue ); } catch (Exception e) { throw new SoftException(e); } }}控制台日志：
