Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'accountDao' is defined
无法找到 accountDao,accountDao被定义在org.phrancol.osgi.jpetstore.dao里面了,于是现在需要使用spring-osgi 来进行跨bundle的引用了。
2,org.phrancol.osgi.jpetstore.dao/META-INF/spring目录中创建一个spring配置文件dataAccessContext-local-osgi.xml,使用<osgi:service>将accountDao和其他被引用的DAO注册成为OSGI Service

Interface that enables beans to find the bundle context they are defined in. Note that in most circumstances there is no need for a bean to implement thisinterface.

本篇文章重点说明什么是函数柯里化,这个语法现象的背后动机是什么,有什么样的应用场景,以及与部分应用函数(Partial Applied Function)之间的联系 1. 什么是柯里化函数
A way to write functions with multiple parameter lists. For instance
def f(x: Int)(y: Int) is a
ApplicationContext能读取多个Bean定义文件,方法是:
ApplicationContext appContext = new ClassPathXmlApplicationContext(
new String[]{“bean-config1.xml”,“bean-config2.xml”,“bean-config3.xml”,“bean-config4.xml

但是用java来实现有一个问题。
由于Java无法像C那样“传递参数的地址,函数返回时能得到参数的值”,唯有新建一个辅助类:AuxClass
import ljn.help.*;
public class BalancedBTree {
BeanUtils.copyProperties VS PropertyUtils.copyProperties
作为两个bean属性copy的工具类,他们被广泛使用,同时也很容易误用,给人造成困然;比如:昨天发现同事在使用BeanUtils.copyProperties copy有integer类型属性的bean时,没有考虑到会将null转换为0,而后面的业
