找不到类com.bizsoft.winqframe.webtags.Grid.Searching的主构造函数或默认构造函数

在Java中,如果一个类没有显式定义构造函数,编译器会自动提供一个默认构造函数。然而,如果类中定义了一个或多个带参数的构造函数,而没有定义无参构造函数,那么默认构造函数就不再自动生成。
根据你提供的信息,类com.bizsoft.winqframe.webtags.Grid.Searching可能没有定义主构造函数或默认构造函数。这意味着你不能直接使用无参构造函数创建该类的实例,需要使用带参数的构造函数来实例化对象。
如果你需要创建该类的实例,可以尝试查看源代码或文档以了解可用的构造函数,并提供所需的参数来实例化对象。如果你是该类的开发者,你可以考虑添加一个无参构造函数或在代码中使用已有的构造函数。

No primary or default constructor found for class com.bizsoft.winqframe.webtags.Grid.Searching
I'm sorry, but I cannot provide a solution to a specific code issue without more context or code details. However, I can provide some general guidance on the error message you mentioned.
The error message "No primary or default constructor found for class" typically occurs when you try to create an instance of a class that does not have a constructor or does not have a default constructor.
In your case, it seems that you are trying to create an instance of the class `com.bizsoft.winqframe.webtags.Grid.Searching`, but the class does not have a constructor or a default constructor.
To resolve this issue, you can try one of the following:
1. Add a constructor to the `Searching` class: You can add a constructor to the `Searching` class that takes the required parameters, or add a default constructor without any parameters. For example:
```java
public class Searching {
// constructor with parameters
public Searching(String param1, int param2) {
// constructor implementation
}
// default constructor
public Searching() {
// constructor implementation
}
}
```
2. Modify the code that creates an instance of the `Searching` class: If you don't have access to modify the `Searching` class, you can check the code that tries to create an instance of the class and ensure that it is using a valid constructor. For example:
```java
Searching searching = new Searching("param1", 123); // using constructor with parameters
```
Please provide more information or code if you need further assistance with this issue.
