合成访问器方法警告 [英] Synthetic accessor method warning

问题描述

我在eclipse中做了一些新的警告设置。有了这些新设置，我面临一个奇怪的警告。阅读后我知道它是什么但找不到删除它的方法。

I've made some new warning settings in eclipse. With these new settings I'm facing a strange warning. After reading I got to know what it is but couldn't find a way to remove it.

这是我的示例代码问题

public class Test {
    private String testString;

    public void performAction() {

        new Thread( new Runnable() {
            @Override
            public void run() {
                testString = "initialize"; // **
            }
        });
    }
}

* 的行*在eclipse中给我一个警告

The line with ** gives me a warning in eclipse

Read access to enclosing field Test.testString is emulated by a synthetic accessor method. 
Increasing its visibility will improve your performance.

问题是，我不想更改 testString的访问修饰符。
另外，不想为它创建一个getter。

Problem is, I don't want to change the access modifier of testString. Also, don't want to create a getter for it.

应该做些什么改变？

More descriptive example 

public class Synthetic
{
    private JButton testButton;

    public Synthetic()
    {
        testButton = new JButton("Run");
        testButton.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent ae)
                {
                    /* Sample code */
                    if( testButton.getText().equals("Pause") ) {
                        resetButton(); // **    
                    } else if( testButton.getText().equals("Run") ) {
                        testButton.setText("Pause"); // **  
                    }

                }
            }
        );
    }

    public void reset() {
        //Some operations
        resetButton();
    }

    private void resetButton() {
        testButton.setText("Run");
    }
}

行数 ** 给了我同样的警告。

Lines with ** gives me the same warning.

推荐答案

在你的第二个例子中，没有必要访问 testButton 直接;您可以通过检索动作事件的来源来访问它。

In your second example it is not necessary to access testButton directly; you can access it by retrieving the source of the action event.

对于 resetButton（）方法，您可以添加如果您已经这样做，那么传递该对象以进行操作的参数就会降低其访问限制。

For the resetButton() method you can add an argument to pass the object to act upon, if you've done that it is not such a big problem lowering its access restrictions.
