SPRING注入FIELD值
Spring注入field值
嘿嘿，今天偷懒，就记一点点内容，然后去看PPLIVE去！
注入field值
FieldRetrievingFactoryBean用来获得目标bean的field值。获得的值可注入给其他bean，也可直接定义成新的bean.
for example:
--------------------------------------------------------
package org.viking.spring.imp;
public class Son
{
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
--------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="son" + son.getAge());
}
}
--------------------------------------------------------
下面这个是field值定义成bean实例。只需修改applicationContext.xml和测试类。
--------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="son" + son.getAge());
System.out.println("系统获取theAge的值: " +app.getBean("theAge"));
}
}
