1:IOC的概述  
IOC(控制反转 Inversion of Control ),是Spring容器的内核,Aop,事务申明等功能都是在ioc基础之上开花结果。主要解决的问题，代码解耦，设计模式，代码重构和优化等。

案例如下：在项目的src目录下新建一个bean.xml如下：

2:IOC的类型  
  a:构造函数注入

b:setter属性注入

3:Java基础知识(反射)和 类装载器 ---ClassLoader  
 A:类装载器就是寻找类的字节码文件并构造出类在jvm内部表示的对象组件，在Java中，类装载器吧一个类装入到 jvm中，要经过以下步骤：  
  类装载：负责查询和加载class文件  
   
B:链接：执行校验，准备和解析步骤，其中解析步骤是可以选择的：  
 a：校验：检查载入class文件数据的正确性。  
 b：准备：给类静态变量分配存储空间。  
 c：解析：讲符号引用转成直接引用。  
  
C:初始化，对静态变量，静态代码库执行初始化工作。

4:资源访问和加载Resource

![201510110109194.jpg][]  
  
为了访问不同类型的资源，必须使用相应的Resource实现类，这是比较麻烦的，是否可以在不显示使用Resource实现类的情况下，进通过资源地方特殊表示就可以加载相应的资源文件呢？Spring通过了强大的加载资源的进制，不但能够通过classpath: file:等可以通过ant风格访问资源地址。  
![201510131636502.jpg][]  
其中在classpath:对应的还有一种写法就是classpath\*:，这个是什么含义呢，如果在一个项目中有个包com.tz.config存放了我们需要加载的资源文件。那么  
classpath:com/tz/config/bean.xml 只会加载第一个，如果一个项目中有多个com.tz.config包的话就会加载所有包下面的资源文件.  
假如项目中有三个模块分别资源文件都放入了在com.tz.config目录下分别是bean1.xml,bean2.xml,bean3.xml 。  
使用classpath\*:com/tz/config/bean\*.xml 可以成功加载三个模块的配置文件。而使用classpath:com/tz/config/bean\*.xml只会加载第一个模块的配置文件。  
使用Ant风格资源地址支持3中匹配符：  
? : 匹配文件名中一个字符  
\*:匹配文件名中任意个字符  
\*\*:匹配多层路径  
如下：  
classpath:com/tz/bean/bean?xml 可以匹配这个目录下com/tz/bean/bean.xml/ bean2.xml  
classpath:com/tz/b?an/bean.xml 可以匹配这个目录下com/tz/b z an/bean.xml,com/tz/bCan/bean.xml等  
classpath:com/\*.xml ：匹配所有的com下面的文件,记住了不包含孙子类元素  
classpath:com/\*\*/bean.xml 匹配所有的com下面的文件, 包含孙子类元素下所有的bean.xml的资源文件。比如：com/tz/bean.xml,com/tz/config/bean.xml 并且包括com/bean.xml  
  
Spring资源加载器:  
  
![201510131711272.jpg][]  
  
Spring的ResourceLoader接口仅有一个getResource(String location)的方法，可以根据一个资源地址加载文件资源，不过如果支持Ant风格的资源文件的加载的话，就扩展了一个ResourcePatternResolver的子类，定义了一个getResources(String location)的方法，可以加载ant风格路径的多文件，（想象一下：里面肯定是一个递归加循环的操作，你们说呢）。PathMatchingResourcePatternRessolver是Spring提供的标准实现，专门用来加载和解析配置文件的。
