初尝 JFinal 项目
temp1:
与JAVA项目类似，有属性方法、操作方法、Sql语句操作、jdbc、配置文件
对比：|| JAVA： Bean / Srv(Server) / SqlMap / jdbc.properties / SqlMapConfig、struts ||
|| JFinal： Model / Controller / 省略 / jdbc.properties / JFinalConfig ||
temp2:
属性：JavaBean手动添加属性并获取get/set方法。 例：private int id; ——> Source ——> Generate Getters and Setters...
JFinalModel自动添加属性不需要获取get/set方法。 例： private static final long serialVersionUID = 1L;
public static final JFinalModel dao = new JFinalModel();
操作：JavaSrv直接书写增删更查方法。
例：private String returnStr;

jdbc无区别
配置文件区别： JAVA配置：Struts.xml
例：<!-- Login action -->
<action name="Login_*" class="LoginAction" method="{1}">
<interceptor-ref name="defaultStack" />
<interceptor-ref name="checkUser" />
<result name="succeed" type="redirectAction">Login_toIndex.action</result>
<result name="toindex">ace/main_page.jsp</result>
<result name="fail">Login.jsp</result>
<result name="login">Login.jsp</result>
</action>
JFinal配置：JFinalConfig.java
例：/**
* jFinal路由配置
*/
@Override
public void configRoute(Routes me) {
me.add("/", IndexController.class); // 访问系统跳入登录页
me.add("/user", UserController.class); // User管理
me.add("/roles", RolesController.class);// 角色管理
me.add("/auths", AuthsController.class);// 权限管理
}
/***
* 数据库连接配置
*/
@Override
public void configPlugin(Plugins me) {
C3p0Plugin c3p0 = new C3p0Plugin(getProperty("jdbc.url"), getProperty("jdbc.username"),
getProperty("jdbc.password"));
c3p0.setDriverClass(getProperty("jdbc.driverClassName"));
me.add(c3p0);
ActiveRecordPlugin arp = new ActiveRecordPlugin(c3p0);
me.add(arp);
arp.setDialect(new AnsiSqlDialect());
arp.setContainerFactory(new CaseInsensitiveContainerFactory());
arp.addMapping("roles", RolesModel.class);// 角色表
arp.addMapping("auths", AuthsModel.class);// 权限表
arp.addMapping("roleAuths", RoleAuthsModel.class);// 角色权限表
}
/***
* 启动运行时运行
*/
public void afterJFinalStart() {
}
/**
* 建议使用 JFinal 手册推荐的方式启动项目
* 运行此 main 方法可以启动项目，此main方法可以放置在任意的Class类定义中，不一定要放于此
*/
public static void main(String[] args) {
JFinal.start("WebRoot", 8080, "/", 5);
}
