我有一个由 Jackson、Jersey、EclipseLink 和 Tomcat 提供支持的小型 RESTful Web 服务。在大多数情况下,XML 都按预期工作,但涉及到我的嵌套子元素时除外。当 XML 文档的其余部分没有时,它们是用命名空间属性编写的。这是响应 XML 的示例:
<userView>
<userIdSID>5</userIdSID>
<userAuthLevel>5</userAuthLevel>
<userRoles>
<roleSID xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:decimal">1</roleSID>
<roleSID xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:decimal">3</roleSID>
<roleSID xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:decimal">2</roleSID>
<roleSID xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:decimal">8</roleSID>
<roleSID xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:decimal">5</roleSID>
<roleSID xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:decimal">4</roleSID>
<roleSID xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:decimal">9</roleSID>
<roleSID xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:decimal">1000001</roleSID>
</userRoles>
</userView>
这就是我的 UserRoleList.java 的样子:
package com.company.project;
import java.io.Serializable;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
@XmlAccessorType(XmlAccessType.FIELD)
public class UserRoleList implements Serializable {
private int userRoleSID;
public int getUserRoleSid() {
return userRoleSID;
}
public void setUserRoleSid(int userRoleSid) {
this.userRoleSID = userRoleSid;
}
}
这就是我的 UserView.java 的样子:
package com.company.project;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;
@Entity
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement
public class UserView implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Basic(optional = false)
@Column(name = "USER_ID_SID")
private String userIdSID;
@Basic(optional = true)
private String userAuthLevel;
@XmlElementWrapper(name = "userRoles")
@XmlElement(name = "roleSID")
private List<UserRoleList> userRoleList = new ArrayList<UserRoleList>();
public UserView() {
}
public UserView(String userIdSID) {
this.userIdSID = userIdSID;
}
public String getUserIdSID() {
return userIdSID;
}
public void setUserIdSID(String userIdSID) {
this.userIdSID = userIdSID;
}
public List<UserRoleList> getUserRoleList() {
return userRoleList;
}
public void setUserRoleList(List<UserRoleList> userRoleList) {
this.userRoleList = userRoleList;
}
public String getUserAuthLevel() {
return userAuthLevel;
}
public void setUserAuthLevel(String userAuthLevel) {
this.userAuthLevel = userAuthLevel;
}
}
这就是我填充该嵌套元素的方式,它采用 2 个入站参数并通过实体管理器执行查询:
List<UserRoleList> userRoleList = em.createNamedQuery("findRoleListByLoginName")
.setParameter(1, id)
.setParameter(2, client)
.getResultList();
关于我可能遗漏什么的任何想法?我尝试使用 pkg-info 无济于事。请注意,此输出构造了一个没有从中生成模式的 XML。不确定这是否有帮助或阻碍,但任何帮助将不胜感激。
