数据库：Oracle 9i
JDBC驱动：OJDBC14
开发环境：Eclipse-JEE
Spring版本：Spring 2.0.6
Hibernate版本：Hibernate Core 3.2.5/Hibernate Annotation 3.3.0/Hibernate Validator 3.0.0/Hibernate Search 3.0.0 Beta4

//jdbc.properties（JDBC配置文件）
jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@192.168.0.3:1521:itone
jdbc.username=test
jdbc.password=test

//hibernate.properties（Hibernate配置文件）
hibernate.dialect=org.hibernate.dialect.Oracle9Dialect
hibernate.show_sql=false
hibernate.cache.use_query_cache=true
hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider
hibernate.hbm2ddl.auto=update
######以下是Hibernate Search的简单配置######
hibernate.search.default.directory_provider=org.hibernate.search.store.FSDirectoryProvider
hibernate.search.default.indexBase=E:/indexes

     

java 代码

//Foo.java（Hibernate POJO文件）
@Entity
@Table(name = "search_foo")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
@Indexed(index = "search_foo")
public class Foo implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@DocumentId
private Integer id;

@Column(nullable = false, length = 256)
@Field(name = "name", index = Index.TOKENIZED, store = Store.YES)
private String name;

@Lob
@Field(name = "content", index = Index.TOKENIZED, store = Store.YES)
private String content;

@Column(name = "post_time", nullable = false)
@DateBridge(resolution = Resolution.DAY)
private Calendar postTime;

public Integer getId() {
     return id;
}

public void setId(Integer id) {
     this.id = id;
}

public String getName() {
     return name;
}

public void setName(String name) {
     this.name = name;
}

public String getContent() {
     return content;
}

public void setContent(String content) {
     this.content = content;
}

public Calendar getPostTime() {
     return postTime;
}

public void setPostTime(Calendar postTime) {
     this.postTime = postTime;
}
}

java 代码

/SpringMVC、Log4j、EHCache配置略

//FooManager.java（做全文检索示例）
package com.itone.search.manager;

@SuppressWarnings("unchecked")
public void testQuery() throws Exception {
     QueryParser parser = new QueryParser("name", new StopAnalyzer());
     Query luceneQuery = parser.parse("name:Jack");
     FullTextSession s = Search.createFullTextSession(getSession());
     FullTextQuery query = s.createFullTextQuery(luceneQuery, Foo.class);
     List&ltFoo> result = query.list();
     for(Foo f : result) {
      System.out.println("ID:" + f.getId());
      System.out.println("NAME:" + f.getName());
