springMVC的配置文件路径问题

①

<init-param>
　　<param-name>contextConfigLocation</param-name>
　　<param-value>classpath:applicationContext.xml</param-value>
 </init-param>

路径：1，src目录下 2，src\main\resources目录下

②不使用classpath

<param-value>/WEB-INF/applicationContext.xml</param-value>

③不写<init-param>时

<servlet>

<servlet-name>dispatch</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</servlet>

默认为xxx-servlet.xml，默认路径为/WEN-INF/xxx-servlet.xml(XXX为servlet-name即是：dispatch)

即是：dispatch-servlet.xml

另：url路径问题

举例1：

1. @Controller
2. @RequestMapping("/welcome")
3. public class HelloWorldController {
4. @RequestMapping(value="/hello" ,method=RequestMethod.GET)
5. public String printWelcome(ModelMap model){
6. model.addAttribute("message" ,"Spring 3 MVC Hello World");
7. return "hello";     }
8. }
9. url：http://localhost:8080/demo1/welcome/hello

举例2：

1. @Controller
2. public class HomeController {
3. @RequestMapping("home")
4. public String home(){
5. return "home";  }
6. }
7. url：http://localhost:8080/demo1/home

web.xml

1. </servlet>
2. <servlet-mapping>
3. <servlet-name>dispatch</servlet-name>
4. <url-pattern>/</url-pattern>
5. </servlet-mapping>

application.xml

1. <context:component-scan base-package="com.vito.action" />
2. <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
3. <property name="prefix" value="/WEB-INF/jsp/" />
4. <property name="suffix" value=".jsp" />
5. </bean>
