Puntos imprescindibles de Spring MVC

1. Configurar DispatcherServlet en el archivo web.xml

   <servlet>
   <servlet-name>dispatcher</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   <init-param>
    <param-name>contextConfigLocation</param- nombre>
    <valor-param>classpath:applicationContext.xml</valor-param>
   </init-param>
   <load-on-starup>1</load-on-starup>
  </servlet>
 
  <servlet-mapping>
   < servlet-name>dispatcher</servlet-name>
   <url-pattern>/</url-pattern>
  </servlet-mapping>

2. Coloque applicationContext.xml

  2.1 Actualización <context:component-scan base-package="controller"></context:component-scan>

  2.2 添加@RequestMapping注解的bean <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
 
                                                                  <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>

  2.3 添加viewResolver的bean <bean id="viewresolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
                                                   <property name="prefix" value="/jsp/"></property>
                                                   <property name ="sufijo" valor=".jsp"></propiedad>
                                                 </bean>

3. Escribir clase java

@Controller
@RequestMapping("/txl")
public class txl {  @ModelAttribute("txl")  public List model(){   List fuck=new ArrayList();   fuck.add("anotación");   fuck.add("ilusión");   volver joder;  }  @RequestMapping("/all")  public String all(){   return "txl";  }  @RequestMapping("/agregar")  public String agregar(){   return "agregar";  } }
