Using conditions to dynamically exclude POJO property in Jackson json serialization

让人想犯罪 __ 提交于 2019-11-27 19:32:28
问题 I have a requirement to dynamically exclude certain property within a List of a defined POJO. The main POJO to be serialized is: public class Foo { List<Bar> bar; public void setBar(List<Bar> bar) { this.bar = bar; } public List<Bar> getBar() { return this.bar; } public static class Bar { private int id; private boolean ignoreId; private String name; public void setId(int id) { this.id = id; } public int getId() { return this.id; } public void setIgnoreId(boolean ignoreId) { this.ignoreId =

How can I generate entity (POJO) from database model using IntelliJ IDEA 10. I create "Data source" in IntelliJ but I have not any idea how can I generate the POJO. UPDATE: In IntelliJ 16 this feature in now implemented. The steps to do it are: 1. Database view context menu 2. Scripted Extensions 3. Generate POJOs You can read more here: Feature request: allow "generate classes from database schema" for plain-JDBC developers First you need tell intelliJ that you are using Hibernate (I guess you are if you need the orm pojo of the table) Go to "Project structure" ( alt + ctrl + shift + s ) In

Why shouldn't I use immutable POJOs instead of JavaBeans?

好久不见. 提交于 2019-11-27 16:55:28
I have implemented a few Java applications now, only desktop applications so far. I prefer to use immutable objects for passing the data around in the application instead of using objects with mutators (setters and getters ), also called JavaBeans. But in the Java world, it seems to be much more common to use JavaBeans, and I can't understand why I should use them instead. Personally the code looks better if it only deals with immutable objects instead of mutate the state all the time. Immutable objects are also recommended in Item 15: Minimize mutability , Effective Java 2ed . If I have an

POJO's versus Cursors in Android

孤街醉人 提交于 2019-11-27 10:19:45
问题 I usually tend to define the model layer of my apps using POJO's, such as Article, Comment, etc. I was about to implement an AlphabetIndexer in the adapter of one of my ListViews. Right now this adapter accepts a Collection of Articles, which I normally get from my wrapper around an SQLiteDatabase. The signature of the AlphabetIndexer constructer is as follows: public AlphabetIndexer (Cursor cursor, int sortedColumnIndex, CharSequence alphabet) Since this doesn't accept a Collection or

getters and setters performing additional logic

浪子不回头ぞ 提交于 2019-11-27 03:08:05
问题 I have a Java class which represents the correlation between two elements (typical POJO): public class Correlation { private final String a; private final String b; private double correlation; public Correlation(String a, String b) { this.a = a; this.b = b; } public double getCorrelation() { return correlation; } public void setCorrelation(double correlation) { this.correlation = correlation; } } To follow the correct correlation logic if a equals b then the correlation value should be ALWAYS

Is it possible to bind a StringProperty to a POJO's String in JavaFX?

末鹿安然 提交于 2019-11-27 02:58:04
问题 I'm creating an application using JavaFX 2. I intend to isolate the UI from data and logics. Considering that, I have a lot of data objects like this: public class Entity { private String m_Value; public Entity(String value) { m_Value = value; } public String getValue() { return m_Value; } public void setValue(String value) { m_Value = value; } } I'm having a hard time creating a binding between the m_Value attribute and the textProperty of a Label, for instance.

How can I iterate over a map of <String, POJO>?

I've got a Map<String, Person> (actually I'm using a more complex POJO but simplifying it for the sake of my question) Person looks like : class Person { String name; Integer age; //accessors } How can I iterate through this map, printing out the key, then the person name, then the person age such as : System.out.println(String.format("Key : %s Name : %s Age : %s", a, b, c)); A being the key from Map< String , Person> B being the name from Person.getName() C being the age from Person.getAge() I can pull all of the values from the map using .values() as detailed in the HashMap docs , but I'm a

What is POJO & DOJO in JAVA? [closed]

问题 I have many doubts in POJO. And seek for a clear definition with a tiny example. 回答1: POJO Plain Old Java Object. Basically a class with attributes and it's getters and setters. public class User{ private String name; private int age; public void setName(String name){ this.name = name; } public String getName(){ return this.name; } //same for age } DOJO haven't heard of it. A JavaScript framework. :) 回答2: pojo : plain old java object dojo : http://dojotoolkit.org/ A javascript ajax framework

What's the advantage of POJO?

为君一笑 提交于 2019-11-27 01:53:32
In my project I have a small data structure Key . public class Key implements Serializable { private static final long serialVersionUID = 1L; public String db; public String ref; public Object id; protected Key() { } public Key(String db, String ref, Object id) { this.db = db; this.ref = ref; this.id = id; } } Yes this class is simple and every field is publicly accessible. But someone has suggested I use POJO style classes instead but when I asked why they were unable to tell me. In my opinion , calling getters and setters is slower than direct access to a field. So why I must use POJO
