考虑以下POJO:
public class User {
private String name;
/* + getter/setter */
}
以下REST WebService:
@Path("Department")
public class DeptoREST {
@GET @Path("{id}")
public List<User> getEmployeesList( Integer id ) {
return dao.fetchEmployeesFromDepto( id );
}
}
这是结果输出:
<users>
<user><name>Usr 1</name></user>
<user><name>Usr 2</name></user>
<user><name>Usr 3</name></user>
</users>
如果没有包装类,是否可以将输出更改为:
<employees>
<employee><name>Usr 1</name></employee>
<employee><name>Usr 2</name></employee>
<employee><name>Usr 3</name></employee>
</employees>
答案 0 :(得分:0)
您可以包装列表,而不是单个User
对象:
@XmlRootElement(name="employees")
public static class EmployeeList {
@XmlElement(name = "employee")
private List<User> users;
public EmployeeList() {
users = Collections.emptyList();
}
public EmployeeList(List<User> users) {
this.users = users;
}
public List<User> getUsers() {
return users;
}
}
然后:
return new EmployeeList(dao.fetchEmployeesFromDepto( id ));
