Dear Spring Community,

 

I am pleased to announce the availability of Spring Data MongoDB 1.0.0 M4. Here are the most important features added:

 

 
• Support for map-reduce operations in MongoTemplate
 
• Provided means to use externalized queries to be executed by repositories
 
• Support for geoNear queries on MongoTemplate and the repositories
 
• New DocumentCallbackHandler interface on MongoTemplate
 
• A DB wide WriteConcern can now be configured on the SimpleDbFactory
 
• A WriteConcern configurable on MongoFactoryBean
 
• Added a QuerydslRepositorySupport base class to ease implementing Querydsl based repositories
 
• Configurable TypeMapper interface to control how type information is written and retrieved to and from Mongo documents
 

 

Beyond that we ship a ton of bug fixes and improvements mostly around the mapping subsystem and performance. For a detailed list of tickets fixed have a look at the changelog.

The elements to be marshalled must be public, or have the XMLElement anotation. The ArrayList class and your class Books do not match any of these rules. You have to define a method to offer the Book values, and anotate it.

On your code, changing only your Books class adding a "self getter" method:

@XmlRootElement
@XmlSeeAlso({Book.class})
public class Books extends ArrayList<Book> {
  public Books() {
    this.add(new Book("The Sign of the Four"));
  }

  @XmlElement(name = "book")
  public List<Book> getBooks() {
    return this;
  }
}

when you run your marshalling code you'll get:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<books><book><title>The Sign of the Four</title></book></books>
