java将对象数组列表转换为POJO

也许http://dozer.sourceforge.net可以为您提供帮助。它是可通过xml配置的映射库。

我很快尝试了这个：

public class Main {  public static void main(String[] args) {    Object[] obj = new Object[3];    obj[0] = new Integer(10);    obj[1] = new Long(2346246234634L);    obj[2] = "Hello";    Collections.singletonList("mapping.xml");    DozerBeanMapper mapper = new DozerBeanMapper(Collections.singletonList("mapping.xml"));    PojoObject pojo = mapper.map(obj, PojoObject.class);    System.out.println(pojo);  }  public static class PojoObject {    private Integer integer;    private Long longg;    private String string;    public PojoObject() {}    public Integer getInteger() {      return integer;    }    public void setInteger(Integer integer) {      this.integer = integer;    }    public Long getLongg() {      return longg;    }    public void setLongg(Long longg) {      this.longg = longg;    }    public String getString() {      return string;    }    public void setString(String string) {      this.string = string;    }    @Override    public String toString() {      return String.format("Pojo content: %d, %d, %s", integer, longg, string);    }  }}

我的mappings.xml看起来像这样：

<?xml version="1.0" encoding="UTF-8"?><mappings xmlns="http://dozer.sourceforge.net" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://dozer.sourceforge.net      http://dozer.sourceforge.net/schema/beanmapping.xsd">    <mapping>        <class-a>java.lang.Object[]</class-a>    <class-b>ch.romix.dozertest.Main.PojoObject</class-b>        <field>        <a>this[0]</a>        <b>Integer</b>    </field>    <field>        <a>this[1]</a>        <b>Longg</b>    </field>    <field>        <a>this[2]</a>        <b>String</b>    </field>    </mapping></mappings>

不幸的是，它仅将10映射到所有三个PojoObject属性。也许您可以看到错误并使用代码段。也许这是Dozer中的一个错误…我找不到使用的任何示例
