在spring3.02现在有个新特性可以让你用一个Java类当作一个bean标签来使用,所以spring的配置文件只需要写2句话就可以了如果要带上事务的话则3句,配置spring的代码如下:

@Configuration

public class BeanConfig {

private static PropertiesFactory factory = PropertiesFactory.getInstance();

@Bean(name = { \ })

public BasicDaoIf basicDao() { return BasicDaoFactory.getBasicDao(); }

@Bean(name = { \ })

public BasicDataSource dataSource() {

BasicDataSource bds = new BasicDataSource(); bds.setDriverClassName((String) factory

.getPropertyValueOrProperties(\));

bds.setUrl((String) factory.getPropertyValueOrProperties(\)); bds.setUsername((String) factory

.getPropertyValueOrProperties(\)); bds.setPassword((String) factory

.getPropertyValueOrProperties(\));

return bds; }

@Bean(name = { \ })

public SessionFactory getSessionFactory() throws Exception { AnnotationSessionFactoryBean sessionFactoryBean = new AnnotationSessionFactoryBean();

sessionFactoryBean.setDataSource(this.dataSource());

sessionFactoryBean.setHibernateProperties((Properties) factory .getPropertyValueOrProperties(\)); String packagesToScan = (String) factory

.getPropertyValueOrProperties(\); String[] packages = packagesToScan.split(\); if (null == packages) { sessionFactoryBean

.setPackagesToScan(new String[] { packagesToScan }); } else {

sessionFactoryBean.setPackagesToScan(packages); }

sessionFactoryBean.afterPropertiesSet(); return sessionFactoryBean.getObject(); }

@Bean(name = { \ })

public HibernateTemplate getHibernateTemplate() throws Exception { HibernateTemplate hibernateTemplate = new HibernateTemplate(); hibernateTemplate.setSessionFactory(this.getSessionFactory()); return hibernateTemplate; }

@Bean(name = { \ })

public HibernateTransactionManager getHibernateTransactionManager() throws Exception {

HibernateTransactionManager hibernateTransactionManager = new HibernateTransactionManager();

hibernateTransactionManager.setSessionFactory(this.getSessionFactory()); return hibernateTransactionManager; } }

bean中有个地方需要读取properties所以还需要加入一个读取配置文件的工厂 PropertiesFactory:

public class PropertiesFactory {

private static final String FILE = \;

private static PropertiesFactory propertiesFactory = new PropertiesFactory();

private InputStream in;

private Properties p;

public static PropertiesFactory getInstance() {

return propertiesFactory; } /**

* 创建一个新的实例 PropertiesFactory. * */

private PropertiesFactory() { super(); }

public void init() {

in = this.getClass().getClassLoader().getResourceAsStream(FILE); }

public Object getPropertyValueOrProperties(final String property) { try { init();

p = new Properties(); p.load(in);

if (StringUtils.isNotEmpty(property)) return p.getProperty(property); else

return p;

} catch (Exception e) { e.printStackTrace(); return null; } }

springApplicationContext.properties: url:驱动地址

driverClassName:驱动名称

username:数据库名字 password:数据库密码

packages:spring要扫描的包以,多个以分割

# JDBC Config

url=jdbc:mysql://localhost:3306/testUser driverClassName=com.mysql.jdbc.Driver username=root password=root

#Hibernate Config

hibernate.dialect=org.hibernate.dialect.MySQLDialect hibernate.hbm2ddl.auto=update hibernate.format_sql=true hibernate.show_sql=true

#Spring Config

packages=org.lxh.bean

[使用心得]maven2之m2eclipse使用手册之四编写通用Dao实例(四) 测试的bean:

@Entity

@Table(name=\)

public class User extends AbstractBean{

private static final long serialVersionUID = -2512193728050258334L; @Id

@GeneratedValue(strategy = GenerationType.IDENTITY) public final Integer getId() { return id; }

@Column(length=50,nullable=false) public String getUserid() { return userid; }

@Column(length=1)

public Integer getUsertype() { return usertype; }

@Column(length=2)

public Integer getRoleid() { return roleid; }

@Column(length=50)

public String getUseragent() { return useragent; }

@Column(length=100)

public String getNickname() { return nickname; }

@Column(length=50)

public String getName() { return name; }

@Column(length=10) public String getSex() { return sex; }

@Column(length=6) public Short getAge() { return age; }

@Column(length=20)

public String getCardid() { return cardid; }

@Column(length=50)

public String getEmail() { return email; }

@Column(length=50)

public String getPassword() { return password; }

@Temporal(TemporalType.DATE) public Date getRgtime() { return rgtime; }

@Temporal(TemporalType.DATE) public Date getUptime() {
