spring 自动装配、注解

一、spring配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"
	default-lazy-init="true">
	<description>Spring公共配置文件</description>
	
	<!-- 属性文件读入 -->
	<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<list>
				<value>classpath*:config/jdbc.properties</value>
			</list>
		</property>
	</bean>

	<!-- 使用annotation 自动注册bean,并检查@Required,@Autowired的属性已被注入 -->
	<context:component-scan base-package="com.xinghuo.zfsjgx" />


	<!-- 使用annotation定义事务 -->
	<!-- 支持 @Transactional 标记 Enable @Transactional support -->
	<tx:annotation-driven transaction-manager="transactionManager" />

	<!-- Hibernate配置 -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="configLocation" value="classpath:hibernate.cfg.xml"/>
		<property name="namingStrategy">
			<bean class="org.hibernate.cfg.ImprovedNamingStrategy" />
		</property>
		
		<property name="hibernateProperties">

		<!-- -->
		<property name="eventListeners">

	</bean>
	 
	<bean id="saveUpdateEventListener" class="com.xinghuo.zfsjgx.dao.VipEntityListener" ></bean>
	<!-- 事务配置 -->
	<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>
</beans>

 

二、manager

package com.xinghuo.zfsjgx.service.sys;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.xinghuo.zfsjgx.dao.sys.SzPcsDAO;
import com.xinghuo.zfsjgx.entity.sys.SzPcs;

/**
* SzPcsManager.java 
* 用@Transactional注明类里的每个方法都用事务的,对只读方法注明readOnly=true加强性能.
* AutoGenerated by XMP 1.2
* 2013-8-13 14:14:48
* @author 
* @see SzPcsDAO
* 
*/
 
@Service
@Transactional
public class SzPcsManager {
	/** TODO  如果是另外一种方式，请用DAO ，用此方式去在spring的配置文件中设置
	private SimpleHibernateTemplate<SzPcs, String> szPcsDAO;

	@Autowired
	public void setSessionFactory(SessionFactory sessionFactory) {
		szPcsDAO = new SimpleHibernateTemplate<SzPcs, String>(sessionFactory, SzPcs.class);
	}
	*/
	
	
	private SzPcsDAO szPcsDAO;

	@Autowired
	public void setSzPcsDAO(SzPcsDAO szPcsDAO) {
		this.szPcsDAO = szPcsDAO;
	}	
	
	
	
	//SzPcsDAO
	
	@Transactional(readOnly = true)
	public SzPcs getSzPcs(String id) {
			return szPcsDAO.get(id);
	}
	
	@Transactional(readOnly = true)
	public List<SzPcs> getAllSzPcss() {
		return szPcsDAO.findAll();
	}
	
	
	public void deleteSzPcs(String id) {
		SzPcs szPcs =  szPcsDAO.get(id);
		 szPcsDAO.delete(szPcs);
	}

	public void deleteSzPcs(SzPcs szPcs) {
		szPcsDAO.delete(szPcs);
	}
	
	public void saveSzPcs(SzPcs szPcs) {
		szPcsDAO.save(szPcs);
	}
	
	public List<SzPcs> getSzPcsList(){
		return szPcsDAO.getSzPcsList();
	}
}

 

三、bean

package com.xinghuo.zfsjgx.entity.sys;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;

import com.xinghuo.zfsjgx.entity.VipEntity;

/**
 * SysUser entity.
 */
@SuppressWarnings("serial")
@Entity
@Table(name = "SYS_USER", uniqueConstraints = {})
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class SysUser extends VipEntity implements java.io.Serializable {

	// Fields

	private String userId;

	private String userPassword;

	private SysPerson sysPerson;


	// Constructors

	/** default constructor */
	public SysUser() {
	}

	/** minimal constructor */
	public SysUser(String userId) {
		this.userId = userId;
	}

	// Property accessors
	@Id
//	@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "seqSysUser")
//	@SequenceGenerator(name = "seqSysUser", sequenceName = "SEQ_SYS_USER", allocationSize = 1)
	@Column(name = "USER_ID", unique = true, nullable = false, insertable = true, updatable = true, length = 20)
	public String getUserId() {
		return this.userId;
	}

	public void setUserId(String userId) {
		this.userId = userId;
	}

	@Column(name = "USER_PASSWORD", unique = false, nullable = true, insertable = true, updatable = true, length = 20)
	public String getUserPassword() {
		return this.userPassword;
	}

	public void setUserPassword(String userPassword) {
		this.userPassword = userPassword;
	}
	
	@ManyToOne(cascade = {}, fetch = FetchType.LAZY)
	@JoinColumn(name = "PERSON_ID", unique = false, nullable = true, insertable = true, updatable = true)
	public SysPerson getSysPerson() {
		return sysPerson;
	}

	public void setSysPerson(SysPerson sysPerson) {
		this.sysPerson = sysPerson;
	}
}
