org.dozer.MappingException:找不到字段的读取或写入方法 [英] org.dozer.MappingException: No read or write method found for field

问题描述

org.dozer.MappingException:找不到字段的读取或写入方法 (class(class)中的(tarShipMethodCode.lmCourier.courierName) com.essilor.ong.domain.inventory.POLocationEntity)

org.dozer.MappingException: No read or write method found for field (tarShipMethodCode.lmCourier.courierName) in class (class com.essilor.ong.domain.inventory.POLocationEntity)

在构建我的war文件并尝试运行Tomcat时出现此错误. 我正在使用JPA和推土机映射. 谁能告诉我如何解决?

I am getting this error when i build my war file and try to run Tomcat. I am using JPA and dozer mapping. Can anyone tell me how to fix it?

推荐答案

检查您的Bean和Dozer映射文件.

Check your Beans and your Dozer-Mapping-File.

可能存在多个(或多或少常见)错误:

There are multiple (more or less common) errors possible:

映射文件中的

• Typo.检查您的POLocationEntity中的包和字段名称，它是否有一个名为tarShipMethodCode的字段，并且是否有一个ImCourier字段，以及一个courierName字段?

• Typo in the mappingfile. Check the package and field names in your POLocationEntity, does it have a field named tarShipMethodCode, and does this have an ImCourier field, and this a courierName field?

缺少吸气剂/吸气剂.再次检查bean，Dozer通常希望使用getFieldName和setFieldName方法，除非您指定了其他方法(我不认为这些方法可能会发布您的映射文件).

Lack of getters / setters. Again check the beans, Dozer usually expects getFieldName and setFieldName methods, unless you specified others (which I do not assume, maybe post your mapping file).

缩小问题范围:这是唯一不起作用的字段吗?还是根本不指定此字段? Dozer倾向于尝试按名称映射在映射文件中没有相应条目的字段，这可能会导致意外错误.

Narrow the problem down: Is this the only field that is not working? Or is this field not specified at all? Dozer tends to try to map-by-name fields that do not have corresponding entries in the mapping file, which could lead to unexpected errors.

tl; dr

有了更多信息(映射xml，bean代码)，这将更易于分析，但是上述指针是根据我的经验解决了这类问题的指针.

With some more information (mapping xml, bean code) this would be easier to analize, but the above pointers are the ones that solve these kinds of problems in my experience.
