代码如下:

RiskLevel.java

import lombok.Data;
import lombok.*;

import java.util.List;

@Data
@Builder
@EqualsAndHashCode(callSuper = false)
@NoArgsConstructor
@AllArgsConstructor
public class RiskLevel {

    private Rule rule;
    private List<String> colors;
}

Rule.java

import lombok.Data;
import lombok.*;

import java.util.List;
@Data
@Builder
@EqualsAndHashCode(callSuper = false)
@NoArgsConstructor
@AllArgsConstructor
public class Rule {

    private List<Integer> province;

    private List<Integer> city;

    private List<Integer> area;

}

RiskMapper.java

import com.xxx.entity.RiskLevel;
import com.xxx.mybatis.MyBaseMapper;
import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface RiskMapper extends MyBaseMapper<RiskLevel> {  //报错地方
}

MyBaseMapper.java

import tk.mybatis.mapper.common.Mapper;
import tk.mybatis.mapper.common.MySqlMapper;

public interface MyBaseMapper<T> extends Mapper<T>, MySqlMapper<T>{
}

解决方法：RiskLevel添加主键id

import lombok.Data;
import lombok.*;

import java.util.List;

@Data
@Builder
@EqualsAndHashCode(callSuper = false)
@NoArgsConstructor
@AllArgsConstructor
public class RiskLevel {
    private Integer id;
    private Rule rule;
    private List<String> colors;
}
