java - 如何打印一种 setter/getter

Question

我有如下代码:

public static void main(String[] args) throws Exception {
    printGettersSetters(PodmiotSzukajQueryFormSet.class);
}

public static void printGettersSetters(Class aClass) {
    Method[] methods = aClass.getMethods();

    for (Method method: methods) {
        if (isGetter(method)) {
            System.out.println("getter: " + method);    
        }
    }
}

public static boolean isGetter(Method method) {
    if (!method.getName().startsWith("getSomething")) {
        return false;
    }
    if (method.getParameterTypes().length != 0) return false;
    if (void.class.equals(method.getReturnType())) return false;
    return true;
}

输出:

getter: public package.package.Class package.package.Class.getSomething()

如何获得该 getter 的类型，在本例中为:“Class”，但在其他示例中为“String”、“int”等。

--编辑有可能.getModifiers() 但它返回 int。如何返回字符串？

Answer 1

想想你在寻找什么方法getReturnType()对象的 java.lang.reflect.Method

public Class getReturnType()

Returns a Class object that represents the formal return type of the method represented by this Method object.

Returns:the return type for the method this object represents
