讀值文件

Question

這裏是我的代碼，我想讀「從My.properties文件TESTME變量。

public class TestToCheckProperties { 

    private int testMe; 

     public void setTestMe(int testMe) { 
    this.testMe = testMe; 
     } 

    public static void main(String args[]){ 
     ApplicationContext context = new ClassPathXmlApplicationContext("classpath:/META-INF/spring/bean/dfp-web-beans.xml"); 
     TestToCheckProperties testToCheckProperties=context.getBean(TestToCheckProperties); 
     System.out.println("testMe: "+testToCheckProperties.testMe); 
} 

這是我Spring.XML 我已經創建了一個bean類TestToCheckProperties：

<bean id='TestToCheckProperties' class="com.My.Code.TestToCheckProperties" > 
     <property name="testMe" value="${My.code.TestToCheckProperties}" /> 
    </bean> 

這是我My.Property文件，我想讀在我的課該值：

#TestToCheckProperties 
My.code.TestToCheckProperties=10 

這裏是我得到

Answer 1

聲明錯誤：

TestToCheckProperties testToCheckProperties = 
    context.getBean(TestToCheckProperties); 

是無效的。它應該是：

TestToCheckProperties testToCheckProperties = 
    (TestToCheckProperties) context.getBean("TestToCheckProperties");
