spring与hibernate整合

spring2.5+hibernate3.3整合：

jar包：

hibsrnate核心包下：
hibernate3.jar
lib/required/*.jar
lib/optional/ehcache-1.2.3.jar
hibernate注解包下的lib/test/slf4j12.jar

spring安装包下的
dist/spring.jar
dist/modules/spring-webmvc-struts.jar
lib/jakarta-commons/commons-logging.jar
lib/aspectj/aspectjweaver.jar/aspectjrt.jar
lib/cglib/cglib-nodep_2.1.3.jar
lib/j2ee/common-annotations.jar
lib/log4j/log4j-1.2.15.jar

第一步：

导入jar包，spring有关包，hibernate有关包，数据库有关包。

第二步：

编写beans.xml配置文件

装载数据源：

<context:property-placeholder location="classpath:jdbc.properties"/>  
    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverClassName}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="maxPoolSize" value="${jdbc.maxPoolSize}"/>
        <property name="minPoolSize" value="${jdbc.minPoolSize}"/>
        <property name="initialPoolSize" value="${jdbc.initialPoolSize}"/>
        <property name="maxIdleTime" value="${jdbc.maxIdleTime}"/>
        <property name="acquireIncrement" value="${jdbc.acquireIncrement}"/>
    </bean>

注册sessionFactory：

　　<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="mappingResources">
            <list>
                <value>cn/itcast/domain/Person.hbm.xml</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <value>
                hibernate.dialect=org.hibernate.dialect.MySQLDialect
                hibernate.hbm2ddl.auto=update
                hibernate.show_sql=true
            </value>
        </property>
    </bean>

sessionFactory中mappingResources加载映射文件，hibernateProperties属性配置hibernate一些配置属性，dataSource属性配置数据源

如果spring需要使用二级缓存的话，将二级缓存的cfg.xml中的信息也放在hibernateProperties的value属性中。

springframework还提供了OpenSessionInView过滤器，我们可以自行配置用于hibernate开发。例子：

   
  <!-- spring的openSessionInView过滤器 -->
  <filter>
      <filter-name>openSessionInView</filter-name>
      <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
  </filter>
  <filter-mapping>
      <filter-name>openSessionInView</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping>

注册事务管理器（使用的是spring的hibernate事务管理器）：

<!-- 注册事务管理器 -->
    <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

剩下的代码和普通的hibernate开发，普通的spring开发差不多了。

使用sessionFactory操作数据库：

@Transactional @Service("personService")
public class PersonServiceBean implements PersonService {
    
    @Resource(name="sessionFactory")
    private SessionFactory sessionFactory;
    
    public void save(Person person){
        //spring会自动帮我们管理session
        sessionFactory.getCurrentSession().persist(person);
    }

注意：

　　使用sessionFactory操作数据库，sessionFactory的getCurrentSession()方法得到Session，而不是使用openSession()方法，因为spring自动帮我们管理session。

　　操作方法可以使用persisit()和merge方法替代save()和update(),表现更好点罢了！

至于hibernate映射文件等其他和前面没什么区别。

package cn.itcast.domain;

public class Person {
    private Integer id;
    private String name;
    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 Person() {
        super();
    }
    
    public Person(Integer id, String name) {
        super();
        this.id = id;
        this.name = name;
    }
    public Person( String name) {
        super();
        this.name = name;
    }
