定义切点
public class LoggingPointcut implements Pointcut { @Override public ClassFilter getClassFilter() { return ClassFilter.TRUE; // 适用于所有类 } @Override public MethodMatcher getMethodMatcher() { return new NameMatchMethodMatcher() { @Override public boolean matches(String methodName, Class<?> targetClass) { return methodName.startsWith("get"); // 适用于所有以 "get" 开头的方法 } }; } } -
定义切面类
public class LoggingAdvisor extends DefaultPointcutAdvisor { public LoggingAdvisor() { super(new LoggingPointcut(), new LoggingAdvice()); } } -
