整理SpringMvc01（返回页面（string））

记录SpringMvc01（最简单的demo1）

新建一个HelloWorldController类

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

/**访问路径：

 *  http://localhost:8080/SpringMvc01/helloWorld
 * @author 81046
 *
 */
@Controller
public class HelloWorldController {


@RequestMapping("/helloWorld")
public String helloWorld(Model model){
model.addAttribute("message", "StringMvc 你好！");
return "helloWorld";
}

}

配置文件spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">


<!-- 使用注解的包，包括子集（改为自己对应的包） -->
    <context:component-scan base-package="com.springMvc"/>


    <!-- 视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp"></property>
</bean>

</beans>
