Springmvc的基本配置
- springmvc坐標(biāo)
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.2.16.RELEASE</version>
</dependency>
- 配置servlet,相當(dāng)于是所有的請(qǐng)求都走了這一個(gè)servlet,然后spring會(huì)把這servlet里面 很多公用的東西封裝好,controller里面只需要處理邏輯就可以了
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<--!配置初始化的文件地址-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
- 創(chuàng)建controller
@Controller
public class FuckBeautiful {
@RequestMapping("/fuckBeautiful")
public String saveUser()
{
System.out.println("saveUser.......ddd");
return "success.jsp";
}
}
- 創(chuàng)建spring-mvc.xml,并配置組件掃描,跟上面2里面的初始值里面的xml對(duì)應(yīng)
<context:component-scan base-package="com.example.FirstSoring.web"></context:component-scan>
<!-- 配置內(nèi)部資源視圖解析器-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
- 啟動(dòng),可以開(kāi)始訪問(wèn)了
- mvc的配置,缺少這個(gè),就沒(méi)法配置注解驅(qū)動(dòng)和開(kāi)發(fā)資源訪問(wèn)這兩個(gè)了
xmlns:mvc="http://www.springframework.org/schema/mvc"
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
<!-- 注解驅(qū)動(dòng)-->
<mvc:annotation-driven/>
<!-- 開(kāi)發(fā)資源訪問(wèn),如果識(shí)別不了得資源,丟給tomcat去實(shí)現(xiàn)-->
<mvc:default-servlet-handler/>
