resteasy

resteasy其实是个很好用的类库,下面介绍下如何使用Resteay去
在JAXB和JSON中进行转换。注意resteasy使用的是Jettison JSON library
(地址:http://jettison.codehaus.org/)

1) pom.xml文件的设置
   <repositories>
<repository>
<id>JBoss repository</id>
<url>https://repository.jboss.org/nexus/content/groups/public-jboss/</url>
</repository>
  </repositories>

  <dependencies>

<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jaxrs</artifactId>
<version>2.2.1.GA</version>
</dependency>

<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jaxb-provider</artifactId>
<version>2.2.0.GA</version>
</dependency>

<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jettison-provider</artifactId>
<version>2.2.0.GA</version>
</dependency>

  </dependencies>

2)写一个类,使用JAXB

Java代码  收藏代码

    import javax.xml.bind.annotation.XmlAttribute; 
    import javax.xml.bind.annotation.XmlElement; 
    import javax.xml.bind.annotation.XmlRootElement; 
      
    @XmlRootElement(name = "movie") 
    public class Movie { 
      
        String name; 
        String director; 
        int year; 
      
        @XmlElement 
        public String getName() { 
            return name; 
        } 
      
        public void setName(String name) { 
            this.name = name; 
        } 
      
        @XmlElement 
        public String getDirector() { 
            return director; 
        } 
      
        public void setDirector(String director) { 
            this.director = director; 
        } 
      
        @XmlAttribute 
        public int getYear() { 
            return year; 
        } 
      
        public void setYear(int year) { 
            this.year = year; 
        } 
      
    } 




3) 然后我们就可以把上面的pojo类转变为json了,看下jboss的reseteasy是如何做的,
 
Java代码  收藏代码

    import javax.ws.rs.GET; 
    import javax.ws.rs.Path; 
    import javax.ws.rs.Produces; 
    import org.jboss.resteasy.annotations.providers.jaxb.json.BadgerFish; 
      
    @Path("/json/movie") 
    public class JSONService { 
      
        @BadgerFish 
        @GET 
        @Path("/get") 
        @Produces("application/json") 
        public Movie getMovieInJSON() { 
      
            Movie movie = new Movie(); 
            movie.setName("Transformers: Dark of the Moon"); 
            movie.setDirector("Michael Bay"); 
            movie.setYear(2011); 
      
            return movie;  
      
        } 
      
    } 



4 当访问“/json/movie/gets"时,就显示对应的json了

Java代码  收藏代码

    { 
        "movie": 
        { 
            "@year":"2011", 
            "director":{ 
                "$":"Michael Bay" 
            }, 
            "name":{ 
                "$":"Transformers: Dark of the Moon" 
            } 
        } 
    }
