<!--配置自動掃描包-->
<context:component-scan base-package="mao.shu.springmvc"/>
<!--配置視圖解析器-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--
prefix 定義路徑字首
suffix 定義路徑字尾
則請求的路徑将會被拼湊為/WEB-INF/pages/"路徑名稱".jsp
-->
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
- 建立請求處理類,使用"@RequestMapping" 注解設定請求路徑,
package mao.shu.springmvc.action;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloWorld {
@RequestMapping("/HelloWorld")
public String execute(){
System.out.println("Hello World");
return "success";
}
}
