I'm not sure if you'd consider it 'standard', but <a href="http://www.devx.com/Java/Article/42946/1954" rel="noreferrer">Project Lombok</a> addresses this problem. They use annotations to replace much of the verbosity of Java.

Some people are looking at alternative Java sibling languages, such as Groovy or Scala. I'm afraid it will take some years -if at all- before the JSR figures out a "standardized" way to "fix" this in Java proper.

blocks|key|1150951|text|Eclipse有一个上下文菜单选项，它将自动为您生成这些内容，我相信许多其他IDE都会这样做。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1150952|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I've created some annotations that are not eclipse-specific.

See <a href="http://code.google.com/p/javadude/wiki/Annotations" rel="noreferrer">http://code.google.com/p/javadude/wiki/Annotations</a>

For example:

<pre><code>package sample;

import com.javadude.annotation.Bean;
import com.javadude.annotation.Property;
import com.javadude.annotation.PropertyKind;

@Bean(properties={
 @Property(name="name"),
 @Property(name="phone", bound=true),
 @Property(name="friend", type=Person.class, kind=PropertyKind.LIST)
}) 
public class Person extends PersonGen {
}
</code></pre>

My annotations generate a superclass; I think Lombok modifies the actual class being compiled (which is officially not supported by Sun and may break - I could be wrong about how it works, but based on what I've seen they must be doing that)

Enjoy!

blocks|key|1241612|text|大多数IDE提供了生成代码的快捷方式(例如，+->：右键单击->+Source+->+Generate+Getters+&+Setters)，尽管我意识到这可能不是您想要的答案。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1241613|有些IOC框架允许您对属性进行注释，以便它们可以在框架的上下文中使用，例如Tapestry+IOC和最新的Spring，我认为(但是这种使用被框架限制了使用)|1241614|entityMap^0|M|1B|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

Most IDEs provide a shortcut for generating the code (e.g. Eclipse: Right click -> Source -> Generate Getters &amp; Setters), although I realise this is probably not the answer you are looking for. 

Some IOC frameworks allow you to annotate properties so that they can be used in the context of the framework e.g. Tapestry IOC, and the latest Spring, I think (but this use is limted to use by the framework)

As a possible alternative, have you tried <a href="http://www.scala-lang.org/" rel="nofollow noreferrer">Scala</a>? It compiles to Java bytecode, and has lots of interesting shortcuts which can make your life as a Java programmer easier.

Properties for instance:

<pre><code>case class Person(var name:String, 
 var age:Int);
val p = Person("John", 4)
p.name
p.name = "Charlie"
p.name
</code></pre>

And the output:

<pre><code>defined class Person
p: Person = Person(John,4)
res7: String = John
res8: String = Charlie
</code></pre>

blocks|key|1151005|text|使用Netbeans时，只需开始输入get或set来替换getter/setter并调用自动完成(Ctrl%2BSpace)，它将为您提供生成getter或setter的选项。它还将为您提供一个生成构造函数的选项。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1151006|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

With Netbeans, just start typing get or set where the getter/setter is to be replaced and call up auto complete (Ctrl+Space), it'll give you the option to generate the getter or setter. It'll also give you an option to generate a constructor as well.

blocks|key|1151010|text|没有比这更好的方法了--没有什么比“属性”关键字更好的了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1151011|正如其他人所提到的，另一种选择是使用您的IDE生成它们。另一种方法是编写自己的代码生成工具，该工具接受基类，并使用getter和setter生成包装器。|1151012|您还可以简单地将变量公开为公共成员。但是，当您决定添加验证逻辑时，这很可能会对您造成伤害。|1151013|但是，最后一个想法是:除非您的类被简单地用于传输数据，否则它们可能不应该公开它们的内部状态。IMO，带有getter和setter的“行为”类是一种代码气味。|1151014|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

There is no better way that's part of the language -- nothing like a "property" keyword.

One alternative, as other people have mentioned, is to use your IDE to generate them. Another, if you have a lot of objects that need this, is to write your own code generation tool that takes a base class and produces a wrapper with getters and setters.

You could also simply expose the variables as public members. However, down the road this will probably come back to hurt you, when you decide to add validation logic.

However, one final thought: unless your classes are used simply to transfer data, they probably shouldn't expose their internal state. IMO, "behavior" classes with getters and setters are a code smell.

blocks|key|1241677|text|是啊，你有点不走运。Groovy确实为您生成了它们，但是在标准java中没有骰子。如果您使用生成它们非常容易，您可以使用hashCode()，以及生成hashCode()和equals()函数。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1241678|entityMap|0|LINK|mutability|MUTABLE|url|http://www.eclipse-blog.org/eclipse-ide/auto-generating-getters-and-setters.html^0|1A|8|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Yeah, you are kind of out of luck. Groovy does generate them for you, but no dice in standard java. If you use Eclipse you can <a href="http://www.eclipse-blog.org/eclipse-ide/auto-generating-getters-and-setters.html" rel="nofollow noreferrer" title="Auto Generating Getters and Seettings in Eclipse">generate them pretty easily</a>, as well as generate hashCode() and equals() functions.

blocks|key|1242058|text|在需要只读类的情况下，请看一看Java记录。它自动生成getter和方法，比如等于和hashcode。但是，这个特性还没有稳定下来，目前您可以使用它作为一个实验性特性(可能会在Java+16上稳定下来)。https://dzone.com/articles/introducing-java-record|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1242059|entityMap|0|LINK|mutability|MUTABLE|url|https://dzone.com/articles/introducing-java-record^0|2U|1E|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

In the case that you need a read-only class, take a look at Java Records. It auto-generates getters and methods like equals and hashcode. However, this feature is not stabilized and currently you can use it as an experimental feature (Probably will be stabilized on Java 16).

blocks|key|2764568|text|使用您的IDE为您生成它，并尽量减少您所拥有的getter/setter的数量--您可能会享受到不可变的额外好处。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2764569|我喜欢属性的C#语法，我认为它很漂亮，很干净，也很干净。|2764570|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Use your IDE to generate it for you and try to minimize the amount of getters/ setters that you have - you will likely enjoy the added benefit of immutability.

I like the C# syntax for properties, I think it's pretty and clean, and pretty clean.

blocks|key|2764581|text|一种选择是不要那么害怕公共领域。对于您知道永远不会在get和set下执行验证或额外工作的简单类，公共字段需要更少的样板、更好的语法和更高的效率。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2764582|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Well, one option is don't be so afraid of public fields. For simple classes that you know will never do validation or extra work under the hood on get and set, public fields require less boilerplate, are syntactically nicer, and are more efficient.

Is there a better standard way to create getters and setters in Java?

It is quite verbose to have to explicitly define getters and setters for each variable. Is there a better standard annotations approach?
