我正在使用Retrofit 2.1.0和Retrofit Simple
XML Converter 2.1.0.我添加了simplexmlconverter来使用addConverterFactory方法改进实例.
XML如下
<?xml version="1.0" encoding="UTF-8"?> <RSS xmlns:atom="http://www.w3.org/2005/Atom" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" xmlns:media="http://search.yahoo.com/mRSS/" version="2.0"> <channel> <title>title</title> <description></description> <language>en-us</language> <item> <title>text</title> <link>text</link> <description>text</description> <enclosure url="text" length="2043520" type="image/jpeg" /> <guid isPermaLink="false">text</guid> <pubDate>Fri,17 Jun 2016 11:43 EDT</pubDate> <source url="text">text</source> </item> <item> <title>text</title> <link>text</link> <description>text</description> <enclosure url="text" length="1735257" type="image/jpeg" /> <guid isPermaLink="false">text</guid> <pubDate>Thu,16 Jun 2016 10:17 EDT</pubDate> <source url="text"></source> </item> <item> <title>text</title> <link>text</link> <description>text</description> <enclosure url="text" length="3763157" type="image/jpeg" /> <guid isPermaLink="false">text</guid> <pubDate>Wed,15 Jun 2016 10:02 EDT</pubDate> <source url="text">text</source> </item> </channel> </RSS>
我的改造api客户端相关代码：RetrofitAPIClient
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(loggingInterceptor)
.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.addConverterFactory(SimpleXmlConverterFactory.create())
.build();
apiService = retrofit.create(MyService.class);
ArticleResponse.java
import org.simpleframework.xml.Element; import org.simpleframework.xml.ElementList; import org.simpleframework.xml.Root; import java.util.List; @Root(name = "RSS") public class ArticleResponse { @Element(name = "channel") public Channel channel; public class Channel { @ElementList public List<Article> articles; } }
Article.java
import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Text;
@Element(name = "item")
public class Article {
@Element(name = "title")
private String title;
@Element(name = "link")
private String link;
@Element(name = "description")
private String description;
@Element(name = "enclosure")
private Enclosure enclosure;
@Element(name = "guid")
private String guid;
@Element(name = "pubDate")
private String pubDate;
@Element(name = "source")
private Source source;
public class Enclosure {
@Attribute(name = "url")
private String url;
@Attribute(name = "length")
private long length;
@Attribute(name = "type")
private String type;
}
public class Source {
@Attribute(name = "url")
private String url;
@Text
private String text;
}
}
错误是：
06-18 20:31:22.894 W/System.err: java.lang.RuntimeException: org.simpleframework.xml.core.AttributeException: Attribute 'version' does not have a match in class [my-package].webservice.response.ArticleResponse at line 1 06-18 20:31:22.894 W/System.err: at retrofit2.converter.simplexml.SimpleXmlResponseBodyConverter.convert(SimpleXmlResponseBodyConverter.java:44) 06-18 20:31:22.894 W/System.err: at retrofit2.converter.simplexml.SimpleXmlResponseBodyConverter.convert(SimpleXmlResponseBodyConverter.java:23) 06-18 20:31:22.894 W/System.err: at retrofit2.ServiceMethod.toResponse(ServiceMethod.java:116) 06-18 20:31:22.894 W/System.err: at retrofit2.OkHttpCall.parseResponse(OkHttpCall.java:211) 06-18 20:31:22.894 W/System.err: at retrofit2.OkHttpCall$1.onResponse(OkHttpCall.java:106) 06-18 20:31:22.894 W/System.err: at okhttp3.RealCall$AsyncCall.execute(RealCall.java:133) 06-18 20:31:22.894 W/System.err: at okhttp3.internal.NamedRunnable.run(NamedRunnable.java:32) 06-18 20:31:22.894 W/System.err: at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1112) 06-18 20:31:22.894 W/System.err: at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:587) 06-18 20:31:22.894 W/System.err: at java.lang.Thread.run(Thread.java:818) 06-18 20:31:22.894 W/System.err: Caused by: org.simpleframework.xml.core.AttributeException: Attribute 'version' does not have a match in class [my-package].webservice.response.ArticleResponse at line 1 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Composite.readAttribute(Composite.java:494) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Composite.readAttributes(Composite.java:413) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Composite.access$300(Composite.java:59) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Composite$Builder.read(Composite.java:1382) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Composite.read(Composite.java:201) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Composite.read(Composite.java:148) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Traverser.read(Traverser.java:92) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Persister.read(Persister.java:625) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Persister.read(Persister.java:606) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Persister.read(Persister.java:584) 06-18 20:31:22.895 W/System.err: at org.simpleframework.xml.core.Persister.read(Persister.java:543) 06-18 20:31:22.895 W/System.err: at retrofit2.converter.simplexml.SimpleXmlResponseBodyConverter.convert(SimpleXmlResponseBodyConverter.java:36) 06-18 20:31:22.895 W/System.err: ... 9 more
解决方法
尝试使用strict = false：
@Root(name = "RSS",strict = false) public class ArticleResponse { @Element(name = "channel") public Channel channel; public class Channel { @ElementList public List<Article> articles; } }
