在与泽西岛一起在Java Rest服务中生产和消费JSON时，会异常

Question

  public class Message {
            private long id;
            private String message;
            private Date created;
            private String author;
            public Message(long id, String message, String author) {    
                this.id = id;
                this.message = message;
                this.author = author;
                this.created = new Date();
            }
            public long getId(
) {

消息是模型类..... 这是methord： -

@POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)       
    public Message addMessage(Message msg){
        return mssageService.addMessage(msg);
    }

上面的方法用于生产并消耗JSON

这是输出： -

        <hr/>
        <p>
            <b>type</b> Exception report

        </p>

这是具有异常代码java.lang.nosuchmethoderror：org.eclipse.persistence.oxm.xmlunmarshaller.setnamespaceresolver异常

Answer 1

可能，您使用eclipselink的旧版本。

我从此站点看到的内容：http：//grepcode.com/project/repo1.maven.org/maven2/org.eclipse.persistence.persistence/eclipselink/

所以我的结论是降级您的eclipselink lib版本。

Answer 2

setNames -paceresolver仅存在Eclipse链接v 2.4，因此将其升级到v2.4或更大
