spring學(xué)習(xí)之util:properties的使用
<util:properties>可用于注入Properties對(duì)象，也可以用于讀取properties文件
1、手動(dòng)配置內(nèi)容
<util:properties id="properties">
<prop key="name">zhangsan</prop>
<prop key="age">age</prop>
<prop key="gender">gender</prop>
</util:properties>
<bean id="phone" class="org.spring.teach.Phone">
<property name="properties" ref="prop"/>
</bean>public class Phone {
private Properties properties;
public void setProperties(Properties properties) {
this.properties = properties;
}
@Override
public String toString() {
return "Phone{" +
"properties=" + properties +
'}';
}
}public class TestCase {
private AbstractApplicationContext app;
@Before
public void before() {
app = new ClassPathXmlApplicationContext("classpath:spring.xml");
}
@After
public void after() {
app.close();
}
@Test
public void test() {
Phone phone = app.getBean("phone", Phone.class);
System.out.println(phone);
}

2、通過(guò)讀取文件獲取內(nèi)容
<util:properties id="properties" location="classpath:db.properties"/>
<bean id="phone" class="org.spring.teach.Phone">
<property name="properties" ref="prop"/>
</bean>public class Phone {
private Properties properties;
public void setProperties(Properties properties) {
this.properties = properties;
}
@Override
public String toString() {
return "Phone{" +
"properties=" + properties +
'}';
}
}public class TestCase {
private AbstractApplicationContext app;
@Before
public void before() {
app = new ClassPathXmlApplicationContext("classpath:spring.xml");
}
@After
public void after() {
app.close();
}
@Test
public void test() {
Phone phone = app.getBean("phone", Phone.class);
System.out.println(phone);
}

3、手動(dòng)配置內(nèi)容和讀取文件一起使用
<util:properties id="properties" location="classpath:db.properties">
<prop key="name">zhangsan</prop>
<prop key="age">age</prop>
<prop key="gender">gender</prop>
</util:properties>
<bean id="phone" class="org.spring.teach.Phone">
<property name="properties" ref="prop"/>
</bean>public class Phone {
private Properties properties;
public void setProperties(Properties properties) {
this.properties = properties;
}
@Override

}
}public class TestCase {
