我在我的应用程序中使用 spring，当我加载 springApplicationContext 以获取 bean 时，我收到错误
Caused by: org.springframework.beans.InvalidPropertyException: Invalid property "abc"
引起：org.springframework.beans.InvalidPropertyException：无效的属性“abc”
Even though there is a property abcand the setter for that property in the bean.
即使abcbean 中有一个属性和该属性的设置器。
This is a weird error i know , but i can't figure out where is the problem.
我知道这是一个奇怪的错误，但我不知道问题出在哪里。
Any pointers will be helpful.
任何指针都会有所帮助。

Ensure that the property has both a public setter and getter. In case of an AnyObjectproperty it should look like:
确保该属性同时具有公共 setter 和 getter。如果是AnyObject属性，它应该如下所示：
private AnyObject abc;
public AnyObject getAbc() { return abc; }
public void setAbc(AnyObject abc) { this.abc = abc; }
There is however one special case: in case of a booleanproperty it should look like:
然而，有一种特殊情况：如果是boolean属性，它应该如下所示：
private boolean abc;
public boolean isAbc() { return abc; }
public void setAbc(boolean abc) { this.abc = abc; }
Note the isprefix instead of get.
注意is前缀而不是get。

I remeber the similar question at Spring forums. It was found out that there was a setter signature like
我记得 Spring 论坛上的类似问题。发现有一个 setter 签名，如
public class MyClass {
private Aggregated field;
public MyClass setField(Aggregated field) {
this.field = field;
}
}
I.e. the setter's return type was not void.
即 setter 的返回类型不是void。
Anyway, Spring uses standard Instrospectorfor processing class properties. Try it with your class and check if target property is found.
无论如何，Spring 使用标准的Instrospector来处理类属性。与您的班级一起尝试并检查是否找到了目标属性。
