问题 Is there a way to map collection size in dozer? class Source { Collection<String> images; } class Destination { int numOfImages; } 回答1: EDIT: I've updated my answer to use a custom converter at the field level instead of at the class level. There might be other solutions but one way to do this would be to use a Custom Converter. I've added getters and setters to your classes and wrote the following converter: package com.mycompany.samples.dozer; import java.util.Collection; import org.dozer

问题 How do you map a single field into a Set in Dozer? I have a class like: class FooDTO { private IdDto bar; private IdDto baz; } class FooDomainObject { private List<Id> ids; } I'd like to map bar and baz into the ids list, but I can't get it to do this. 回答1: I found this on the Dozer support list: http://sourceforge.net/projects/dozer/forums/forum/452530/topic/1557144 Basically, you use this syntax: <field> <a>bar</a> <b>ids[0]</b> <b-hint>org.foo.Id</b-hint> </field> <field> <a>baz</a> <b>ids

关于BeanCopier的一些思考

爱⌒轻易说出口 提交于 2019-12-10 15:09:32
在做业务的时候,我们有时为了隔离变化,会将DAO查询出来的Entity,和对外提供的DTO隔离开来。大概90%的时候,它们的结构都是类似的,但是我们很不喜欢写很多冗长的b.setF1(a.getF1())这样的代码,于是我们需要BeanCopier来帮助我们。 BeanCopier 其实已经有很多开源版本,例如 DozerMapper 、 Apache BeanUtils 、 Spring 、 Jodd BeanUtils 甚至是 Cglib 都提供了这样的功能。在比较这些工具之前,我想先提提我对BeanCopier的一些要求。 1. 性能 BeanCopier是一个很常用的操作,如果是一个批量的请求,就更加明显了。使用效率太低的库不太划算,我对这些工具做了一个对比:Copy一个简单Bean 1,000,000次,计算总耗时(测试代码在 这里 )。比较结果如下: 1,000,000 round jdk set/get takes 17ms cglib takes 117ms jodd takes 5309ms dozer mapper takes 2336ms apche beanutils takes 6264ms 其中jdk的直接写set/get是最快的,所以在性能要求高的场景下倒是不妨自己写。另外这样写也是对重构比较友好,这是其他几个工具都做不到的。
