Spring MVC：找不到其他html文件

-1

爲什麼鏈接http://localhost:8080/demo00/user/沒有工作，說404，如何解決它？我的網站項目結構： website structure Spring MVC：找不到其他html文件

我也跟着一步一些教程一步，但無法弄清楚什麼是錯在這裏。我在Windows 10中使用Eclipse Neon + Tomcat 8 + Java 1.8。請幫忙，提前致謝。

如果有不正確的代碼或結構，請指出。

編輯： 我改變了一些XML和Java文件按照以下建議，並上傳演示項目https://www.dropbox.com/s/k0rahvz4u29jzey/demo00-160828-url-does-no-work.zip?dl=0，請你檢查一下，如果可能的。謝謝。

您是否想將@RequestMapping（「user」）'改爲'@RequestMapping（「/ user」）'並再次測試？ – Khodabakhsh

在UserController.java中，我將@RequestMapping（「user」）'改爲'@RequestMapping（「/ user」）'，但仍然無效。 –

問題是你applicationContext.xml是不是在application bootup時間，最終引發404在applicationContext.xml定義的所有資源進行掃描。爲了使上下文負荷增加文件的web.xmlcontextConfigLocation部分，具體如下：applicationContext.xml

的web.xml

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

    <welcome-file-list> 
     <welcome-file>index.html</welcome-file> 
     <welcome-file>index.htm</welcome-file> 
     <welcome-file>index.jsp</welcome-file> 
     <welcome-file>default.html</welcome-file> 
     <welcome-file>default.htm</welcome-file> 
     <welcome-file>default.jsp</welcome-file> 
    </welcome-file-list> 

    <servlet> 
     <servlet-name>spring</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <init-param> 
      <param-name>contextConfigLocation</param-name> 
      <param-value>/WEB-INF/applicationContext.xml, /WEB-INF/spring-servlet.xml</param-value> 
     </init-param> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>spring</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 
</web-app>

然後取下mvc:resources，並添加<mvc:default-servlet-handler/>和你正在使用Spring 4不更新架構位置Spring 4，而不是Spring 3，具體如下：

<?xml version="1.0" encoding="UTF-8"?>

     <property name="username" value="root" /> 
     <property name="password" value="123456" /> 
    </bean> 

    <!-- Session Factory Declaration --> 
    <bean id="sessionFactory" 
     class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
     <property name="dataSource" ref="dataSource" /> 
     <property name="packagesToScan" value="com.demo.model" /> 
     <property name="hibernateProperties"> 
      <props> 
       <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> 
       <prop key="hibernate.show_sql">true</prop>

       <!-- <prop key="hibernate.hbm2ddl.auto">create</prop> --> 
      </props> 
     </property> 
    </bean> 

    <tx:annotation-driven transaction-manager="transactionManager" /> 

    <bean id="transactionManager" 
     class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 
     <property name="sessionFactory" ref="sessionFactory" /> 
    </bean> 

</beans>

如果你想知道更多關於<mvc:default-servlet-handler />，結賬我的回答here。

除了上述變化，提供UserController.java獨特@RequestMapping網址否則會拋出Circular view path例外，我修改@RequestMapping在類級別/users避免相同，具體如下：

@Controller 
@RequestMapping("/users") 
public class UserController { 

@RequestMapping(value = "", method = RequestMethod.GET) 
public ModelAndView get() { 
    ModelAndView view = new ModelAndView("user"); 
    return view; 
} 
}

現在，打開http://localhost:8080/demo00/users應顯示user.html頁面如下：

經過測試，但沒有奏效。我上傳了這個演示 https://www.dropbox.com/s/k0rahvz4u29jzey/demo00-160828-url-does-no-work.zip?dl=0 如果可能的話，請檢查。謝謝。 –

哇...你做到了！非常感謝你:)我仍然有一個問題，你在類級別修改'@ RequestMapping'到'/ users'來避免這個問題。像什麼一樣？我嘗試了'/ user'和'http：// localhost：8080/demo00/user'，也沒有'Circular view path'發生異常。 –

@ J.W：同樣我的意思是「圓形視圖路徑異常」。由於@RequestMapping（「/ user」）公共類UserController和ModelAndView視圖=新ModelAndView（「用戶」）;返回視圖;'調用相同的URL'/ user'。 – Arpit

我建議你在項目結構和.xml文件中進行一些更改。

1）您應該保留查看文件夾中的WEB-INF文件夾。

2），則可以刪除這些映射： -

<mvc:resources mapping="/view/**" location="/view/" /> 
<mvc:resources mapping="/img/**" location="/img/" /> 
<mvc:resources mapping="/fonts/**" location="/fonts/" /> 
<mvc:resources mapping="/css/**" location="/css/" /> 
<mvc:resources mapping="/js/**" location="/js/" />

3）使用本

屬性名= 「前綴」值= 「/ WEB-INF /視圖/」

而不是此

property name =「prefix」value =「/ view /」

謝謝。而如何CSS，JS，IMG和字體文件夾，他們應該去哪裏？ –

不需要改變這些文件夾的路徑。這些文件夾總是應該在WEB-INF之外。 – rajat

你可以把CSS，JS，IMG和字體文件夾在webapps /下資源的一個位置，並在應用程序上下文文件使該條目下方：

<mvc:resources mapping="/resources/**" location="/resources/" 
    cache-period="31556926" />

而且你可以在你的應用程序上下文文件中刪除以下行：

<mvc:resources mapping="/view/**" location="/view/" /> 
<mvc:resources mapping="/img/**" location="/img/" /> 
<mvc:resources mapping="/fonts/**" location="/fonts/" /> 
<mvc:resources mapping="/css/**" location="/css/" /> 
<mvc:resources mapping="/js/**" location="/js/" />

其次把您查看WEB-INF摺疊並在你的應用程序上下文文件更改的條目：

 <bean id="viewResolver" 
     class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix"> 
      <value>/WEB-INF/view/</value> 
     </property> 
     <property name="suffix"> 
      <value>.html</value> 
     </property> 
    </bean>

的d最後，您可以使用默認get方法編寫您的控制器：不需要使用value屬性，因爲您在這裏沒有給出任何其他url。

@RequestMapping(method = RequestMethod.GET) 
    public ModelAndView get() { 
     ModelAndView view = new ModelAndView("user"); 
     return view; 
    }

那麼你可以打：

http://localhost:8080/demo00/user

試過了，這個鏈接仍然不起作用。但是你的建議正在使代碼結構更加適合和可讀。謝謝。 –
