建立properties檔案

在XML檔案中因為名稱空間

xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context.xsd">
 

引入properties檔案並配置屬性
Value中的值對應properties檔案中的key值。

<context:property-placeholder location="classpath:test.properties"/>
    <bean id="userDao" class="com.cjy.sping5.UserDaoImpl">
        <property name="daoId" value="${prop.name}"> </
 
property>
    </bean>

輸出測試結果

public class UserDaoImpl implements UserDao{


    private String DaoId;

    public void setDaoId(String daoId) {
        DaoId = daoId;
    }

    @Override
    public void update() {
        System.out.println(DaoId+"Dao update");
    }
}

public void
 
 testUser()
    {
        ApplicationContext context= new ClassPathXmlApplicationContext("bean2.xml");

        UserDao userdao= context.getBean("userDao", UserDao.class);
        userdao.update();

    }
