Java 使用web服务时解组异常

java web-services rest

Java 使用web服务时解组异常,java,web-services,rest,Java,Web Services,Rest,我有一个基于许多实体类的web服务。下面是其中之一 @Entity @Table(name = "users") @XmlRootElement @NamedQueries({ @NamedQuery(name = "Users.findAll", query = "SELECT u FROM Users u"), @NamedQuery(name = "Users.findByUserName", query = "SELECT u FROM Users u WHERE u.userName

我有一个基于许多实体类的web服务。下面是其中之一

@Entity
@Table(name = "users")
@XmlRootElement
@NamedQueries({
@NamedQuery(name = "Users.findAll", query = "SELECT u FROM Users u"),
@NamedQuery(name = "Users.findByUserName", query = "SELECT u FROM Users u WHERE u.userName = :userName"),
@NamedQuery(name = "Users.findByUserPassword", query = "SELECT u FROM Users u WHERE u.userPassword = :userPassword")})

public class Users implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@Basic(optional = false)
@Column(name = "user_name")
private String userName;

@Basic(optional = false)
@Column(name = "user_password")
private String userPassword;

@JoinColumn(name = "user_category_id", referencedColumnName = "category_id")
@ManyToOne(optional = false)
private UserCategory userCategoryId;

@OneToMany(cascade = CascadeType.ALL, mappedBy = "userName")
private List<UserRecord> userRecordList;

public Users() {
}

public Users(String userName) {
    this.userName = userName;
}

public Users(String userName, String userPassword) {
    this.userName = userName;
    this.userPassword = userPassword;
}

public String getUserName() {
    return userName;
}

public void setUserName(String userName) {
    this.userName = userName;
}

public String getUserPassword() {
    return userPassword;
}

public void setUserPassword(String userPassword) {
    this.userPassword = userPassword;
}

public UserCategory getUserCategoryId() {
    return userCategoryId;
}

public void setUserCategoryId(UserCategory userCategoryId) {
    this.userCategoryId = userCategoryId;
}

@XmlTransient
public List<UserRecord> getUserRecordList() {
    return userRecordList;
}

public void setUserRecordList(List<UserRecord> userRecordList) {
    this.userRecordList = userRecordList;
}

@Override
public int hashCode() {
    int hash = 0;
    hash += (userName != null ? userName.hashCode() : 0);
    return hash;
}

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

@Override
public String toString() {
    return userName;
}

 }
哪个有这种格式

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<userss>
<users>
    <userCategoryId>
        <categoryId>2</categoryId>
        <userCategory>admin</userCategory>
    </userCategoryId>
    <userName>admin</userName>
    <userPassword>d033e22ae348aeb5660fc2140aec35850c4da997</userPassword>
</users>
</userss>

D033E22AE348AEB5660FC2140AEC3580C4DA997
但是，这行代码

List<Users> l = (List<Users>)c.findAll_XML(Users.class);

listl=（List）c.findAll_XML（Users.class）；
生成一个异常，这似乎是由围绕xml结果的“userss”标记引起的，我不确定这是如何发生的

有人能帮我解决这个问题吗
