Question

我想要排除一个看起来像这样的字段：

List<String> fieldNames = new ArrayList<>();
fieldNames.add("fieldA");
fieldNames.add("fieldB");

我在Dozer网页上看到我可以配置如下：

BeanMappingBuilder builder = new BeanMappingBuilder() {
    protected void configure() {
        mapping(AClass.class, BClass.class,
                TypeMappingOptions.oneWay(),
                mapNull(true)
        )
       .exclude("fieldA") //here i would like to add exclude but the list
    }
};

但我不知道如何在.exclude方法中添加String列表....任何人都可以帮助我吗？

非常感谢！

更新

ClassA{
    private String fieldA, fieldB,fieldC; //so i would like to map just the fieldC
}
ClassB{
    private String fieldA, fieldB,fieldC; //so i would like to map just the fieldC
}

对于映射器配置：

List<String> fieldNames = new ArrayList<>();
fieldNames.add("fieldA");
fieldNames.add("fieldB");

我希望从mappnig中排除字段名。所以当我映射时，我不想映射List变量... 以某种方式与......并排除......

 .exclude(list.foreach(listElement -> listElement.toString())) // or i dont know how can i do that

最后我做了这个解决方案。

DozerBeanMapper mapper = new DozerBeanMapper();
List<String> excludeList = new ArrayList<>();
excludeList.add("fieldA");
BeanMappingBuilder builder = new BeanMappingBuilder() {
            protected void configure() {
                TypeMappingBuilder typeMappingBuilder = mapping(ClassA.class, ClassB.class);
                excludeList.forEach(typeMappingBuilder::exclude);
        };
mapper.addMapping(builder);

如何用Dozer排除java中的字符串列表？
