这是代码
测试类：
 void "newly published blog should at top of recent blog entries"() {
        given:
        def now = new Date()
        blogFacadeService.publish(new BlogEntryDTO(
                title: 'title',
                content: 'content',
                dateCreated: now
    ))
        def entry = blogFacadeService.getRecentEntries(1)[0]        expect:
        entry.title == 'title'
        entry.content == 'content'
        entry.dateCreated == now
    }
服务类：
class BlogFacadeService implements BlogFacade{
    List<BlogEntryDTO> a//列表变量a
    @Override
     void publish(BlogEntryDTO entry){
         
         def p=new BlogEntryDTO(title:entry.title,content:entry.content,dateCreated:entry.dateCreated)
         try{    //捕获异常
          p.save()
           }catch (Exception e){
                 println new String("保存失败！".getBytes(),"utf-8")
throw new RuntimeException(new String("保存失败！".getBytes(),"utf-8"))
           }
         a=p.list(max:10,offset:0,sort:"dateCreated",order:"desc")//排序
           
     }
     @Override
     List<BlogEntryDTO> getRecentEntries(int n){
      List<BlogEntryDTO> b
     for(i in 1..<n+1)
        {
       b=a
       return b
         }
     }
     
}
