jersey.api.MessageException message body writer and MIME media type text/xml not found
提问by Marwan Tushyeh
The data is an object named "QueryResponse" which in turn owns a list of objects called "Todos".
数据是一个名为“QueryResponse”的对象，它又拥有一个名为“Todos”的对象列表。
I get this error:
我收到此错误：
javax.ws.rs.WebApplicationException: com.sun.jersey.api.MessageException: A message body writer for Java class java.util.ArrayList, and Java type java.util.List<de.vogella.jersey.todo.model.Todo>, and MIME media type text/xml was not found
I have this jersey get method:
我有这个球衣获取方法：
@GET
@Produces({"application/xml", "application/json"})
public QueryResponse getTodos() {
List todos = new ArrayList();
todos.addAll(TodoDao.instance.getModel().values());
return new QueryResponse(todos);
}
And that's the QueryResponse object:
这就是 QueryResponse 对象：
@XmlRootElement
public class QueryResponse {
@XmlElementWrapper(name = "Todos")
@XmlElement(name = "Todo")
private List<Todo> todolist;
public QueryResponse(List<Todo> todolist)
{
this.todolist = todolist;
}
public void setTodolist(List<Todo> todolist)
{
this.todolist = todolist;
}
public List<Todo> getTodolist( )
{
return this.todolist;
}
}
And this is the Todo class:
这是 Todo 类：
public class Todo
{
private int id;
private String summary;
private String Description;
public Todo()
{
}
public Todo(int id, String summary)
{
this.id = id;
this.summary = summary;
}
public int getId() {
return this.id;
}
public void setId(int userID) {
this.id = userID;
}
public String getSummary() {
return this.summary;
}
public void setSummary(String summary) {
this.summary = summary;
}
public String getDescription() {
return this.Description;
}
public void setDescription(String description) {
this.Description = description;
}
}
I appreciate your help.
我感谢您的帮助。

Do the following:
请执行下列操作：
- Annotate
public void getTodolist(List<Todo> todolist)with the following annotation:@XmlElementRef - Annotate your QueryResponse with the following annotation:
@XmlSeeAlso({Todo.class})
- 注释
public void getTodolist(List<Todo> todolist)具有以下注释：@XmlElementRef - 使用以下注释对您的 QueryResponse 进行注释：
@XmlSeeAlso({Todo.class})
