我正在尝试使用 elementlistunion 反序列化 List 字段
Customer.java
@ElementListUnion({ @ElementList(inline = false, type = Thing.class),
@ElementList(inline = false, type = AnotherThing.class) })
List<Object> things = new ArrayList<Object>();
Thing 和 AnotherThing 是 2 个 POJO。但我得到以下异常
03-21 18:56:31.940: E/AndroidRuntime(2289): Caused by:
org.simpleframework.xml.core.PersistenceException: Duplicate annotation
of name 'things' on
@org.simpleframework.xml.ElementListUnion(value=
[@org.simpleframework.xml.ElementList(data=false,
empty=true, entry=, inline=false, name=, required=true, type=class
com.data.Thing), @org.simpleframework.xml.ElementList(data=false,
empty=true, entry=, inline=false, name=, required=true, type=class
com.data.AnotherThing)]) on field 'things' java.util.List
com.data.Customer.things
我已经坚持了一整天了。请帮忙。
这是我的回复 xml:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<customer>
<address>
<no>122</no>
<street>xxx</street>
</address>
<id>122</id>
<name>James Bond</name>
<things>
<thing>
<val>185</val>
</thing>
<thing>
<val>162</val>
