如何阻止Simple将“class”属性写入XML文件?

解决方案实际上是 mentioned on project's page ,您必须使用访客。这很简单:

public class ClassAttributeRemoverVisitor implements Visitor {
    @Override
    public void read(Type type, NodeMap<InputNode> node) throws Exception {
        // Do nothing, framework will guess appropriate class on its own
    }

    @Override
    public void write(Type type, NodeMap<OutputNode> node) throws Exception {
        OutputNode element = node.getNode();
        element.getAttributes().remove("class");
    }
}

new Persister(new VisitorStrategy(new ClassAttributeRemoverVisitor()))

@Path("translation")
@ElementMap(inline=true)
Map translation;
