java.lang.NoSuchFieldError的：STANDARD_NUMBER_TYPES

Question

問題： 我得到這個錯誤：

java.lang.NoSuchFieldError: STANDARD_NUMBER_TYPES

情況： 我嘗試添加彈簧JPA春季數據JPA和與此配置調度員servlet.xml中

<?xml version="1.0" encoding="UTF-8"?> 
    <beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" 
     xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" 
     xmlns:jpa="http://www.springframework.org/schema/data/jpa" 
     xsi:schemaLocation=" 
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd 
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 
    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd 
    http://www.springframework.org/schema/data/jpa 
    http://www.springframework.org/schema/data/jpa/spring-jpa-1.1.xsd"> 
... 
<jpa:repositories base-package="pl.test.library.dao"/> 

我越來越黃exlamation標誌（在線路:)

<jpa:repositories base-package="pl.test.library.dao"/> 

，上面寫着：

Unable to locate Spring NamespaceHandler for element 'jpa:repositories' of schema namespace ' http://www.springframework.org/schema/data/jpa '

所以我打賭有一些依賴失蹤。

<dependency> 
      <groupId>org.springframework.data</groupId> 
      <artifactId>spring-data-jpa</artifactId> 
      <version>1.8.1.RELEASE</version> 
     </dependency> 

，並試圖啓動Apache（上最新版本），我只是在服務器啓動時結束收到此錯誤：

root cause java.lang.NoSuchFieldError: STANDARD_NUMBER_TYPES org.springframework.web.context.request.ServletRequestAttributes.(ServletRequestAttributes.java:55) org.springframework.web.servlet.FrameworkServlet.buildRequestAttributes(FrameworkServlet.java:1032) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:959) org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:858) javax.servlet.http.HttpServlet.service(HttpServlet.java:618) org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:843) javax.servlet.http.HttpServlet.service(HttpServlet.java:725) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

也嘗試加入不同的組合後添加下面，沒有運氣也：

<dependency> 
      <groupId>org.springframework.data</groupId> 
      <artifactId>spring-data-commons-core</artifactId> 
      <version>1.4.1.RELEASE</version> 
     </dependency> 
<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-aop</artifactId> 
    <version>4.1.7.RELEASE</version> 
</dependency>

更改shcemaLocation，架構位置似乎是這裏的問題。

從

xsi:schemaLocation=" 
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd 
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 
    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd 
    http://www.springframework.org/schema/data/jpa 
    http://www.springframework.org/schema/data/jpa/spring-jpa-1.1.xsd"> 

到

xsi:schemaLocation=" 
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd 
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 
    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd 
    http://www.springframework.org/schema/data/jpa 
    http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">

這可能是因爲你有你的構建重複春天庫。

如果您使用的是Intellj，您可以檢查您的out/artifacts/.._war_exploded/WEB-INF/lib目錄。
