Error:(15, 13) java: No property named “cType” exists in source parameter(s). Did you mean “CType”?

实体

@Data
public class{
    private String cType;
}

@Mapping(target = "type", source = "cType"),

这问题是由于实体类的属性首字母小写第二个字母大写导致，source的值首字母改为大写就可以了

@Mapping(target = "type", source = "CType"),

springboot 2.3.2 +mapstructct1.4.2.Final +lomback 默认
