小编Bis*_*jit的帖子

我有两个类memberdao和成员类.我在成员类中创建了一个成员类的对象.这是我的代码

require_once('/../dao/memberdao.class.php');

class Member
{
public $objMemberDao= new MemberDao(); 

}

但它给出了一个错误Parse错误:语法错误,第9行的C:\ xampp\htdocs\membership\lib\member.class.php中的意外T_NEW.我是php的新手,所以请帮助

我正在开发hibernate + ehcache程序.

@Entity
@Table(name = "pizza")
public class Pizza implements Serializable{
    @Id
    @GeneratedValue
    private Integer id;
    private String name;
    private double price;

    public long getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

}

ehcache.xml中

  <cache name="com.abp.osp.domain.Pizza"   
maxElementsInMemory="100"   
eternal="false"   
timeToIdleSeconds="5"   
timeToLiveSeconds="200" /> …

嗨,我想从Web服务返回一个列表.我的代码是

public class WebListTest {
    public List serviceFunction(String arg1,String arg2)
    {
    List list=new ArrayList();
        list.add(arg1);
        list.add(arg2);
            return list;    

        }
}

但在wsdl创作中我发现了

<xs:element minOccurs="0" name="return" nillable="true" type="xs:anyType"/>

当从客户端调用此Web服务时,我得到了异常

我想知道如何在java中设置存储唯一数据不重复的值？在存储数据时是否有任何机制集合
