string转@Data @AllArgsConstructor @NoArgsConstructor @TableName("t_user") public class User { @TableField("uid") private Integer uid; @TableField("username") private String username; @TableField("password") private String password; @TableField("salt") private String salt; @TableField("phone") private String phone; @TableField("email") private String email; @TableField("gender") private Integer gender; @TableField("avatar") private String avatar; @TableLogic @TableField("is_delete") private Integer is_delete; }

您可以使用Java反射机制或者其他类似的工具来实现将字符串转换为User类对象。具体的方法可以参考以下示例代码：

import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableLogic;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.lang.reflect.Field;

public class StringToUserConverter {

    public static void main(String[] args) {
        String userStr = "1,john,123456,salt,13512345678,john@example.com,1,avatar.png,0";
        User user = convert(userStr, User.class);
        System.out.println(user);
    }

    public static <T> T convert(String str, Class<T> clazz) {
        String[] fields = str.split(",");
        T obj = null;
        try {
            obj = clazz.newInstance();
            Field[] declaredFields = clazz.getDeclaredFields();
            for (int i = 0; i < declaredFields.length; i++) {
                Field field = declaredFields[i];
                field.setAccessible(true);
                if (field.isAnnotationPresent(TableField.class)) {
                    TableField tableField = field.getAnnotation(TableField.class);
                    String fieldName = tableField.value();
                    Object fieldValue = convertValue(fields[i], field.getType());
                    field.set(obj, fieldValue);
                } else if (field.isAnnotationPresent(TableLogic.class)) {
                    Object fieldValue = convertValue(fields[i], field.getType());
                    field.set(obj, fieldValue);
                }
            }
            if (clazz.isAnnotationPresent(TableName.class)) {
                TableName tableName = clazz.getAnnotation(TableName.class);
                Field tableField = clazz.getDeclaredField("tableName");
                tableField.setAccessible(true);
                tableField.set(obj, tableName.value());
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return obj;
    }

    private static Object convertValue(String value, Class<?> type) {
        if (int.class.equals(type) || Integer.class.equals(type)) {
            return Integer.parseInt(value);
        } else if (String.class.equals(type)) {
            return value;
        } else {
            // TODO: convert other types
            return null;
        }
    }

}

这段代码中，我们首先定义了一个`StringToUserConverter`类，其中包含了一个静态方法`convert`，该方法可以将一个字符串转换为指定类型的对象。在`convert`方法中，我们首先通过反射获取目标类型的所有字段，然后逐个解析输入字符串的各个部分，并将其转换为对应的字段类型。在字段解析过程中，我们通过`@TableField`和`@TableLogic`注解来标识需要解析的字段，同时也支持自定义的注解。在解析完所有字段后，我们还可以通过`@TableName`注解来获取表名，并将其设置到对象的`tableName`字段中。最后，我们返回转换后的对象。在示例代码中，我们将输入字符串转换为了一个`User`对象，并将其输出到控制台上。
