Springframework(6)

二、Spring集成

1、Mail

（1）SimpleMailMessage

l         创建消息

SimpleMailMessage msg = new SimpleMailMessage();

msg.setFrom("[e-mail]");

msg.setTo("[e-mail]");

msg.setCc(new String[] {"[e-mail]", "[e-mail]"});

msg.setBcc(new String[] {"[e-mail]", "[e-mail]"});

msg.setSubject("my subject");

msg.setText("my text");

（2）MailSender

l         定义消息发送者

<bean id="mailSender"

class="org.springframework.mail.javamail.JavaMailSenderImpl">

<property name="host"><value>smtp.mail.org</value></property>

<property name="username"><value>joe</value></property>

<property name="password"><value>abc123</value></property>

</bean>

l         发送消息

MailSender sender = (MailSender) ctx.getBean("mailSender");

sender.send(msg);

 

2、调度（scheduling）

（1）调度程序

l         内建支持：

Ø         Java 2 Timer：Timer、TimerTask

Ø         Quartz：Schedulers、JobDetails、Triggers

（2）ScheduledTimerTask

l         我们想要运行的任务

public class MyTask extends TimerTask {

public void run() {

// do something

}

}

<bean id="myTask"

class="...scheduling.timer.ScheduledTimerTask">

<property name="timerTask">

<bean class="eg.MyTask"/>

</property>

<property name="delay"><value>60000</value></property>

<property name="period"><value>1000</value></property>

</bean>

包装java.util.TimerTask调度的Bean

（3）TimerFactoryBean

l         创建调度器

<bean id="scheduler"

class="...scheduling.timer.TimerFactoryBean">

<property name="scheduledTimerTasks">

<list><ref bean="myTask"/></list>

</property>

</bean>

创建一个java.util.Timer对象

l         在Bean创建时，Timer开始运行

 

3、JNDI

（1）JndiTemplate

l         使用JndiTemplate

Properties p = new Properties();

p.setProperty("java.naming.factory.initial",

"org.jnp.interfaces.NamingContextFactory");

p.setProperty("java.naming.provider.url",

"jnp://localhost:1099");

JndiTemplate jndi = new JndiTemplate(p);

Properties env = jndi.getEnvironment();

try {

jndi.bind("Something", something);

Object o = jndi.lookup("Something");

jndi.unbind("Something");

}

catch(NamingException e) {

...

}

（2）JndiObjectFacroryBean

l         使用Bean替代loopup

<bean id="jndiTemplate"

class="org.springframework.jndi.JndiTemplate">

<constructor-arg>

<props>

<prop key="java.naming.factory.initial">

org.jnp.interfaces.NamingContextFactory</prop>

<prop key="java.naming.provider.url">jnp://localhost:1099</prop>

</props>

</constructor-arg>

</bean>

<bean id="something"

class="org.springframework.jndi.JndiObjectFactoryBean">

<property name="jndiTemplate"><ref bean="jndiTemplate"/></property>

<property name="jndiName"><value>Something</value></property>

</bean>

Object o = ctx.getBean("something");
