使用orika进行对象间Mapping

[java]代码库

package bean_mapping;

import static org.junit.Assert.assertEquals;

import java.util.ArrayList;
import java.util.List;

import ma.glasnost.orika.MapperFacade;
import ma.glasnost.orika.MapperFactory;
import ma.glasnost.orika.impl.DefaultMapperFactory;

import org.junit.Before;
import org.junit.Test;

public class TestBeanMapping {

    MapperFacade mapper = null;

    @Before
    public void init() {
        //创建mapper的工厂类
        MapperFactory factory = new DefaultMapperFactory.Builder().build();
        //注册一个mapper,这段可以同过继承configurableMapper类，配置成spring bean
        factory.registerClassMap(factory.classMap(SourceObj.class, DescObj.class)
            //设置正向空值不复制，反向空值不复制
            .mapNulls(false).mapNullsInReverse(false)
            //相同的字段不需要显示声明
            //.field("prop1", "prop1")
            .field("intProp2", "prop2")
            //List, Array, Map类型的复制方式
            .field("listProp3{}", "prop3{}").mapNulls(true)
            .byDefault().toClassMap());
        //获取mapper        
        mapper = factory.getMapperFacade();
    }

    @Test
    public void testMapping() {
        //构建源对象
        SourceObj source = new SourceObj();
        source.setProp1("test");
        source.setIntProp2("test2");
        List<String> propList = new ArrayList<String>();
        propList.add("TestString");
        propList.add("TestString2");
        source.setListProp3(propList);
        //转换成目标对象
        DescObj desc = mapper.map(source, DescObj.class);
        assertEquals(source.getProp1(), desc.getProp1());
        assertEquals(source.getIntProp2(), desc.getProp2());
        assertEquals(desc.getProp2(), "test2");
        assertEquals(desc.getProp3().size(),2);
    }
