如何列出Java类及其祖先在Eclipse中公开的所有属性？ [英] How to list all properties exposed by a Java class and its ancestors in Eclipse?

问题描述

给出一个单一的Java类，我希望能够列出在所有祖先中公开的所有属性，并递归地遍历所有的暴露属性（即 public 或getter / setters）以同样的方式。

简单的例子说明一下：

  public class BaseClass1 {
 private int intProperty; //有getter和setter（未显示）
} 
 public class SubClass1 extends BaseClass1 {
 private int privateSoNotListed; 
 public SubClass2 subClass2Property; 
} 
 public class BaseClass2 {
 public String stringProperty; 
} 
 public class SubClass2 extends BaseClass2 {
 private long longProperty; //有getter和setter（未显示）
} 
  

给定 SubClass1 作为输入，输出将是这样的：

  intProperty  -  int [from BaseClass1] 
 subClass2Property.stringProperty  -  String [from BaseClass2] 
 subClass2Property.longProperty  -  long [from SubClass2] 
  

应该可以使用一些聪明的反思来写这样的东西，但我宁愿不重新发明 - 有没有现有的工具可以做到这一点一个Eclipse插件？）

编辑： Eclipse的类型层次结构对于显示单个类的属性做出了不错的工作 - 在我心中是理想的解决方案将是如果这是一个树视图（类似于Package Explorer），具有展开本身类的属性的能力。

解决方案

有呃st发现了一种有用的方法，可以通过Eclipse的类型层次结构实现与原始问题相似的东西。

有一个名为显示所有继承的成员的切换，如以下红色箭头：

选择此项后，除了所选类别的字段和方法外，还显示了所有超类的字段和方法（清楚地说明每个类的位置），如下所示：

（当然，这不仅仅包括属性，而是由于getter以字母顺序显示，是公共/私人/保护的图标，可以用来获取这个信息很容易。）

Given a single Java class I'd like to be able to list all properties that are exposed in all ancestors and recursively traverse all their exposed properties (i.e. public or with getters/setters) in the same way.

Easier to explain with a simple example:

public class BaseClass1 {
    private int intProperty; // has getter and setter (not shown)
}
public class SubClass1 extends BaseClass1 {
    private int privateSoNotListed;
    public SubClass2 subClass2Property;
}
public class BaseClass2 {
    public String stringProperty;
}
public class SubClass2 extends BaseClass2 {
    private long longProperty; // has getter and setter (not shown)
}

Given SubClass1 above as input, the output would be something like this:

intProperty                      - int    [from BaseClass1]
subClass2Property.stringProperty - String [from BaseClass2]
subClass2Property.longProperty   - long   [from SubClass2]

It should be possible to write something like this using a bit of clever reflection but I'd rather not reinvent the wheel - is there an existing tool that can do this (perhaps an Eclipse plugin?)

EDIT: Eclipse's Type Hierarchy does a nice job of displaying properties for a single class - the ideal solution in my mind would be if this were a tree view (similar to Package Explorer) with the ability to expand properties that are themselves classes.

解决方案

Have just found a useful way of achieving something fairly similar to what was originally asked via Eclipse's Type Hierarchy.

There is a toggle named "Show All Inherited Members" as shown by the red arrow below:

After selecting this, the fields and methods from all superclasses are displayed in addition to those for the selected class (with a clear indication of where each one came from), as shown below:

(Of course, this includes more than just properties but since the getters are displayed in alphabetical order and there are icons for public/private/protected, it can be used to obtain this information easily enough.)
