Seasar2(S2Container),简单的说,是比Spring一样提供DI功能的框架,但比Sping轻量级。
比理论来说本人更喜欢实际操作和调试,接下来,就让我们开始Seasar2之旅吧。
首先,先下载和安装JDK,Eclipse,Tomcat
JDK 下载: 下载JDK 6 Update 22
Eclipse 下载: 下载Eclipse IDE for Java EE Developers
Tomcat 下载: 下载32-bit Windows zip
接下来,下载Seasar2(S2Container)
下载S2Container
把下载后的S2Container解压缩,主要关注下2个文件夹
「lib」文件夹:包含S2Container以及相关库。
「doc」文件夹:S2Container的相关文档。
接下来,开始用S2Container开发。
使用Eclipse新建项目,「File」⇒「New」⇒「Dynamic Web Project」,项目名叫“seasar”。
把下面jar包拷贝到lib目录下,并加入到Build Path里。
(1)使用S2Container必须的文件
s2-framework-2.4.42.jar
commons-logging-1.1.1.jar
javassist-3.4.ga.jar
ognl-2.6.9-patch-20090427.jar
(2)使用S2AOP必须的文件
aopalliance-1.0.jar
(3)使用Java EE服务器以外的Servlet容器(比如Tomcat)时必须的文件
geronimo-jta_1.1_spec-1.0.jar
新建Bean类(DataBean.java)
