我使用this tutorrial,我创建了这个 table(id,username)打印; 现在我想使用restful web服务向其插入数据
我应该在内容文本框中添加什么内容?
这是我的涂料类

@Override

// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Prints)) {
return false;
}
Prints other = (Prints) object;
if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
return false;
}
return true;
}
@Override
public String toString() {

}
}
我尝试过使用put方法,但是我收到了这个错误
为什么我在组合框中没有post方法?

将请求正文部分放在那里。如果要更新某个实体,那么你应该传递dto,其中包含应该更新的数据。我没有通过你的链接。这个部分可以是Json或XML。(比如下文)
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<prints>
<id>1</id>
<username>test</username>
</prints>
你必须注释你的dto让printDTO如下所示
@XmlRootElement(name = "prints")
public class PrintsDTO {
private int id;
private String username;
// have getters and setteres for above
}

我使用代码使用restful客户端应用程序将数据插入我的restful Web服务,如下所示
NewJerseyClient client = new NewJerseyClient();
Prints p = new Prints();
p.setId(235);
p.setUsername("subhi");
client.create_XML(p);
这对我的案例来说已经足够了
