測試springMVC時候控制器跳轉404

先說一下我的錯誤吧

在配置前端控制器的時候，有一個標籤寫錯了我

使用exclude-filter   類似於把controller註解加入了黑名單 ，使用exclude

表示一般分開加載的時候在加載spring配置文件的時候只掃描@service和@Reposity這些類

修改之後

測試結果：

 

 

下面對應一下我的配置：可以參考查看一下

1.目錄文件

2.web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

  <display-name>Archetype Created Web Application</display-name>

  <!--  配置DisppatcherServlet控制器-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--配置一個DispatcherServlet初始化參數:配置SpringMVC配置文件的位置和名稱-->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:/springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>

  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!--配置springmvc編碼過濾器-->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>
      org.springframework.web.filter.CharacterEncodingFilter
    </filter-class>
    <!--設置過濾中的屬性-->
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>

    <!--啓動過濾器-->
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <!--過濾所有請求-->
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

3.springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">
    <!-- 開啓註解掃描 只掃描Controller註解 -->
       <context:component-scan base-package="com.bhlc">
           <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
       </context:component-scan>

    <!--配置的視圖解析器對象-->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

    <!--設置過濾靜態資源不過濾-->
    <mvc:resources mapping="/css/**" location="/css/"/>
    <mvc:resources mapping="/images/**" location="/images"/>
    <mvc:resources mapping="/js/**" location="/js/"/>

    <!--開啓SpringMVC註解的支持-->
    <mvc:annotation-driven/>
</beans>

4.前端控制類

//AccountController類
@RequestMapping("/account")
@Controller
public class AccountController {
        @RequestMapping("/findAll")
        public String findAll(){
            System.out.println("表現層執行。。。");
            return "out";
        }
}

5.然後就是新建兩個jsp文件進行頁面跳轉了   

（注意，如果檢查配置文件沒錯的話，看看是不是設置的路徑有問題！一般就是這些問題）
