简单示例
加入JAR包
① Spring自身JAR包：spring-framework-4.0.0.RELEASE\libs目录下
spring-beans-4.0.0.RELEASE.jar
spring-context-4.0.0.RELE2ASE.jar
spring-core-4.0.0.RELEASE.jar
spring-expression-4.0.0.RELEASE.jar
② commons-logging-1.1.1.jar
创建 conf source floder
创建 Spring 配置文件
2) 在Spring Tool Suite工具中通过如下步骤创建Spring的配置文件
① File->New->Spring Bean Configuration File
② 为文件取名字 例如：applicationContext.xml
创建 Pserson 类
