Spring 与Struts整合 (五)
整合关键
把Action的创建交给Spring的IOC容器,需要引入jar文件struts2-spring-plugin-x.x.x.x.jar,spring-web-x.x.x.RELEASE.jar
整合步骤
-
新建web项目
-
引入jar
Struts核心jar,Spring core,Spring web
-
配置
bean.xml,struts.xml,web.xml,启动时配置加载Spring IOC容器
web.xml
<context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/bean*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> -
Action类
完整例子
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport{
public UserAction() {
System.out.println("action实例创建！");
}
public String execute() throws Exception {
System.out.println("UserAction.execute()");
return super.execute();
}
