There is no getter for property named 'user_id' in 'class com.taiyi.biz.domain.TPoint'

这个错误提示是在 Java 代码中出现的，意思是在 `TPoint` 类中没有名为 `user_id` 的属性的 getter 方法。你需要检查 `TPoint` 类中是否定义了 `user_id` 属性，并且是否提供了对应的 getter 方法。如果没有定义该属性，你需要考虑在 `TPoint` 类中添加该属性及其 getter 方法。如果该属性已经定义了，你需要确认 getter 方法的命名是否符合规范，即以 `get` 开头，后面紧跟该属性的首字母大写的名称。例如，如果属性名为 `user_id`，则 getter 方法应该命名为 `getUserId()`。

There is no getter for property named 'user_id' in 'class com.taiyi.biz.domain.TPoint'这是什么错误

这个错误提示说明在Java类 com.taiyi.biz.domain.TPoint 中，没有名为 user_id 的属性的 getter 方法。通常，当你使用某个属性时，Java 会自动调对应的 getter 方法来获取属性的值，但是如果这个属性没有对应的 getter 方法，就会抛出这个错误。

你需要在 TPoint 类中添加一个名为 getUser_id 的方法，返回 user_id 属性的值。例如：

public class TPoint {
    private int user_id;

    public int getUser_id() {
        return user_id;
    }

    public void setUser_id(int user_id) {
        this.user_id = user_id;
    }
}

这样就能解决这个错误了。

There is no getter for property named 'user' in 'class com.learn.pojo.User'

As an AI language model, I cannot tell the exact reason for this error without seeing the code. However, based on the error message, it seems that you are trying to access a property named "user" in an instance of the class "com.learn.pojo.User", but there is no getter method defined for this property in the class.

To solve this error, you should define a getter method for the "user" property in the "com.learn.pojo.User" class. The getter method should have the same name as the property and should return the value of the property. Here is an example of how to define a getter method for the "user" property:

public class User {
    private String user;

    public String getUser() {
        return this.user;
    }

    public void setUser(String user) {
        this.user = user;
    }
}

In this example, the "getUser" method is the getter method for the "user" property. It returns the value of the "user" property when it is called. You can now access the "user" property using the "getUser" method without getting the "no getter for property named 'user'" error.
