hibernate search 例子

1、开发环境：spring2.5、hibernate3.3.1GA、hibernateSearch3.1.0GA;

2、开发是基于maven上开发的，首先新建一个web工程，添加maven支持，在pom.xml中添加一下几个依赖包：

      org.apache.openejb
      javaee-api
      5.0-1
      provided


    org.hibernate
    hibernate-search
    3.1.0.GA


        org.hibernate
        hibernate-annotations
        3.4.0.GA






    org.apache.lucene
    lucene-analyzers
    3.0.1


    org.apache.lucene
    lucene-highlighter
    3.0.1

     
  
      org.apache.openejb
      javaee-api
      5.0-1
      provided
    
          
    org.hibernate  
    hibernate-search  
    3.1.0.GA  
	  
	  
	    org.hibernate  
	    hibernate-annotations  
	    3.4.0.GA  
	    
	
  
     
  
  
    org.apache.lucene  
    lucene-analyzers  
    3.0.1  
  
  
    org.apache.lucene  
    lucene-highlighter  
    3.0.1  
  
  

其他就是hibernate+spring的配置了；
注意一点的就是在配置文件hibernate的属性后面加上索引的监听和索引存放的位置，如：

    "sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        "dataSource">
            "dataSource" />

        "hibernateProperties">

                "hibernate.dialect">
                    ${hibernate.dialect}

                "hibernate.hbm2ddl.auto">
                    ${hibernate.hbm2ddl.auto}

                "hibernate.show_sql">
                    ${hibernate.show_sql}

                "hibernate.use_sql_comments">
                    ${hibernate.use_sql_comments}

                "hibernate.use_outer_join">
                    ${hibernate.use_outer_join}

                "hibernate.current_session_context_class">
                    ${hibernate.current.session.context.class}

                "connection.autoReconnect">
                    ${connection.autoReconnect}

                "connection.autoReconnectForPools">
                    ${connection.autoReconnectForPools}

                "connection.is-connection-validation-required">
                    ${connection.is-connection-validation-required}



                "hibernate.search.default.directory_provider">
                    org.hibernate.search.store.FSDirectoryProvider

                "hibernate.search.default.indexBase">
                    d:/JAVA/hibernateIndex






        "eventListeners">

                "post-update">
                    class="org.hibernate.search.event.FullTextIndexEventListener" />

                "post-insert">
                    class="org.hibernate.search.event.FullTextIndexEventListener" />

                "post-delete">
                    class="org.hibernate.search.event.FullTextIndexEventListener" />




        "mappingDirectoryLocations">

                ${hibernate.mappingDirectoryLocations}

	
		
			
		
		
			
				
					${hibernate.dialect}
				
				
					${hibernate.hbm2ddl.auto}
				
				
					${hibernate.show_sql}
				
				
					${hibernate.use_sql_comments}
				
				
					${hibernate.use_outer_join}
				
				
					${hibernate.current.session.context.class}
				
				
					${connection.autoReconnect}
				 
        		
        			${connection.autoReconnectForPools}
        		 
        		
        			${connection.is-connection-validation-required}
        		 
        		
        		
        		
					org.hibernate.search.store.FSDirectoryProvider
				
				
					d:/JAVA/hibernateIndex
				
				 
			
		
		
		
		  
              
		
		
		
			
				${hibernate.mappingDirectoryLocations}
			
		
	

这时启动如果报slf4j错误，可能是你的slf4j包冲突，需要把你lib里相关的jar包删了，在maven支持中还剩下slf4j-api-1.4.2.jar，需要导入slf4j-logging-1.4.2.jar包，如果导入更高版可能会报错，这个包在百度搜slf4j就能进入它的官网，很容易找到；

这个时候启动如果不报错，那成功一半了；接下来就是配置实体类了，比如一个商城系统要对订单建索引，实体类如（给出关键部分代码）：

@Entity
@Indexed(index="shopOrders")
public class ShopOrders  implements java.io.Serializable {


    // Fields

     @DocumentId
     private String id;
     private Integer uid;
     @Field(index=Index.TOKENIZED,store=Store.YES)
     private String username;
     @Field(index=Index.UN_TOKENIZED,store=Store.YES)
     private Integer isDelete;

@Entity
@Indexed(index="shopOrders")
public class ShopOrders  implements java.io.Serializable {


    // Fields    

     @DocumentId
     private String id;
     private Integer uid;
     @Field(index=Index.TOKENIZED,store=Store.YES)
     private String username;
     @Field(index=Index.UN_TOKENIZED,store=Store.YES)
     private Integer isDelete;

这个时候启动你会发现你指定的路径下已经有了一个shopOrders文件夹，如果这个时候去搜索是搜索不到的，还没有初始化数据；
以下是数据初始化和查询的代码：

好了，到这基本就完事了，只需要在service里调用就行了，别忘了，先调用createIndexByHibernateSearch方法初始化（一次就行），再调用search方法搜索；
