【springboot】org.aspectj.lang.ProceedingJoinPoint獲取返回類型、參數名稱/值等

 

1、參數值

Object[] args = joinPoint.getArgs();

 

 2、參數名稱

Signature signature = joinPoint.getSignature();
if (signature instanceof MethodSignature) {
    MethodSignature methodSignature = (MethodSignature) signature;
    String[] properties = methodSignature.getParameterNames();
}

 

3、返回類型

Signature signature = joinPoint.getSignature();
if (signature instanceof MethodSignature) {
    MethodSignature methodSignature = (MethodSignature) signature;
    // 被切的方法
    Method method = methodSignature.getMethod();
    // 返回類型
    Class<?> methodReturnType = method.getReturnType();
    // 實例化
    Object o = methodReturnType.newInstance();
}

 

4、全限定類名

Signature signature = joinPoint.getSignature();
signature.getDeclaringTypeName()

 

5、方法名

Signature signature = joinPoint.getSignature();
signature.getName()

 

 

工具類方法

/**
 * 獲取方法和參數內容
 *
 * @param className 類名 非必填
 * @param mothodName 方法名 必填
 * @param properties 參數名稱列表
 * @param agrs 參數列表
 * @return
 */
public static String getMothodPropertion(String className, String mothodName, String[] properties, Object ... agrs) {
    StringBuilder sb = new StringBuilder();
    if(null != className) {
        sb.append("類名:[").append(className).append("],");
    }
    sb.append("方法:[").append(mothodName).append("]");
    if (null == agrs) {
        return sb.toString();
    }
    boolean flag = null != properties;
    int propertiesLength = properties.length;
    Object obj;
    for(int i = 0, length = agrs.length; i < length; i++) {
        obj = agrs[i];
        sb.append("\r\n參數索引:[").append(i).append("],");
        if (flag && i < propertiesLength) {
            sb.append("參數名稱:[").append(properties[i]).append("],");
        }
        if(null == obj) {
            sb.append("為null");
            continue;
        }
        sb.append("類型:[").append(obj.getClass().getName()).append("],");
        if(obj instanceof Collection) {
            Collection collection = (Collection)obj;
            sb.append("長度:[").append(collection.size()).append("],內容:[").append(collection);
        } else if(obj instanceof Map) {
            Map map = (Map)obj;
            sb.append("長度:[").append(map.size()).append("],內容:[").append(map);
        } else if(obj instanceof Object[]) {
            Object[] objects = (Object[])obj;
            sb.append("長度:[").append(objects.length).append("],內容:[").append(Arrays.asList(objects));
        } else if(obj instanceof String) {
            sb.append("內容:[").append(obj);
        } else {
            sb.append("內容:[").append(String.valueOf(obj));
        }
        sb.append("]");
    }
    return sb.toString();
}

效果如下
