Java gets all get methods and set methods in an object, reads the names of all variables under a class

 

All get methods and set methods 
public void getMethod (Object obj) { 
    Class clazz = obj.getClass (); // Get entity class name 
    Field [] fields = obj.getClass (). GetDeclaredFields (); // Get properties 
    // Get all methods in Object object 
    for (Field field: fields) ( 
        PropertyDescriptor pd = new PropertyDescriptor (field.getName (), clazz); 
        Method getMethod = pd.getReadMethod (); // Get get method 
        //getMethod.invoke ( obj); // Here is the get method of executing the Object object 
        Method setMethod = pd.getWriteMethod (); // Get the set method     
        //setMethod.invoke(obj,"parameter");//Here is to execute the Object The set method of the object 
    } 
} 

Read the names of all variables under a class 
public void getMethod (Class clz) { 
	// Get all the attribute fields in the corresponding class of the f object 
	Field [] fields = clz.getDeclaredFields ();
	for (int i = 0, len = fields.length; i <len; i ++) { 
		// For each attribute, get the attribute name 
		String varName = fields [i] .getName (); 
		System.out.println ("variable The name is: "+ varName); 
	} 
}

All get methods and set methods 
public void getMethod (Object obj) { 
    Class clazz = obj.getClass (); // Get entity class name 
    Field [] fields = obj.getClass (). GetDeclaredFields (); // Get properties 
    // Get all methods in Object object 
    for (Field field: fields) ( 
        PropertyDescriptor pd = new PropertyDescriptor (field.getName (), clazz); 
        Method getMethod = pd.getReadMethod (); // Get get method 
        //getMethod.invoke ( obj); // Here is the get method of executing the Object object 
        Method setMethod = pd.getWriteMethod (); // Get the set method     
        //setMethod.invoke(obj,"parameter");//Here is to execute the Object The set method of the object 
    } 
}
