泽西休息服务显示异常javax.ws.rs.WebApplicationException:javax.xml.bind.MarshalException [英] jersey rest services showing exception javax.ws.rs.WebApplicationException: javax.xml.bind.MarshalException
问题描述
我正在研究球衣服务,我提到 这里 当我返回一个java对象时它工作正常。后来我试图让java对象通用它给出异常
javax.ws.rs.WebApplicationException:javax.xml.bind.MarshalException
I am working on jersey services which i mentioned here it is working fine when i am returning a java object. Later i tried to make the java object generic its giving exception javax.ws.rs.WebApplicationException: javax.xml.bind.MarshalException
@XmlRootElement
public class AppObject<T> implements Serializable {
private List<T> list;
private String license;
public AppObject() {
list = new ArrayList<T>();
}
public AppObject(List<T> list) {
this.list = list;
}
@XmlAnyElement(lax = true)
public List<T> getList() {
return list;
}
public void setList(List<T> list) {
this.list = list;
}
public String getLicense() {
return license;
}
public void setLicense(String license) {
this.license = license;
}
}
我的服务
@GET
@Produces({MediaType.APPLICATION_XML ,MediaType.APPLICATION_JSON})
@Path("/getreq")
public AppObject<DimRequirement> savePayment() {
AppObject<DimRequirement> appObject = new AppObject<DimRequirement>();
appObject.setLicense("4");
Long clientKey=4L;
List<DimRequirement> dimreqlist = dimRequirementDao.getAllByClientNIsCurrent(clientKey);
appObject.setList(dimreqlist);
return appObject;
}
设置为AppObject的DimRequirement
@XmlRootElement
public class DimRequirement extends BaseObject implements Serializable {
private Long requirementKey;
private String description;
private String priority;
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="requirementKey")
public Long getRequirementKey() {
return this.requirementKey;
}
public void setRequirementKey(Long requirementKey) {
this.requirementKey = requirementKey;
}
@Column(name="Description")
public String getDescription() {
return this.description;
}
public void setDescription(String description) {
this.description = description;
}
@Column(name="Priority")
public String getPriority() {
return this.priority;
}
public void setPriority(String priority) {
this.priority = priority;
}
}

但是我不是 能够解决问题。
I referd following links link 1 link 2 but i was not able to solve the problem.
推荐答案
对于 get
方法,相应的 JAXBContext
将构建在类 AppObject
上,而不是类型 AppObject< DimRequirement>
。
For your get
method, the corresponding JAXBContext
will be built on the class AppObject
and not the type AppObject<DimRequirement>
.
@GET
@Produces({MediaType.APPLICATION_XML ,MediaType.APPLICATION_JSON})
@Path("/getreq")
public AppObject<DimRequirement> savePayment() {
你可以制作 JAXBContext
将通过使用 @XmlSeeAlso <在
AppObject
类中创建,知道 DimRequirement
/ code>注释。
You can make the JAXBContext
that will be created on the AppObject
class aware of DimRequirement
by using the @XmlSeeAlso
annotation.
@XmlRootElement
@XmlSeeAlso({DimRequirement.class})
public class AppObject<T> implements Serializable {
