創建時發生Spring bean拋出錯誤

Question

我正在嘗試創建一個bean，並且出現錯誤。我已經縮小到這個特定的bean，並在引用API documents之後，我不明白爲什麼每當我部署我的.war文件時它會被拋出。希望我缺少一些簡單的東西。

這裏是APP-security.xml文件內容：

<?xml version="1.0" encoding="UTF-8"?> 
<beans:beans xmlns="http://www.springframework.org/schema/security" 
    xmlns:beans="http://www.springframework.org/schema/beans" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
     http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd 
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd 
     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd 

    <beans:bean id="contextSource" class="org.springframework.security.ldap.DefaultSpringSecurityContextSource"> 
     <constructor-arg value="ldap://localhost:389/dc=mydomain,dc=com" /> 
     <property name="userDn" value="cn=manager,dc=mydomain,dc=com" /> 
     <property name="password" value="password" /> 
    </beans:bean> 

    <context:annotation-config/> 
    <context:component-scan base-package="my.current.project"/> 

</beans:beans> 

這裏是我的Maven的pom.xml的一個片段：

<properties> 
    ... 
    <spring.security.version>3.1.1.RELEASE</spring.security.version> 
    ... 
</properties> 

<dependencies> 
    ... 
    <dependency> 
     <groupId>org.springframework.security</groupId> 
     <artifactId>spring-security-core</artifactId> 
     <version>${spring.security.version}</version> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework.security</groupId> 
     <artifactId>spring-security-web</artifactId> 
     <version>${spring.security.version}</version> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework.security</groupId> 
     <artifactId>spring-security-config</artifactId> 
     <version>${spring.security.version}</version> 
    </dependency>  
    <dependency> 
     <groupId>org.springframework.security</groupId> 
     <artifactId>spring-security-ldap</artifactId> 
     <version>${spring.security.version}</version> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework.security</groupId> 
     <artifactId>spring-security-taglibs</artifactId> 
     <version>${spring.security.version}</version> 
    </dependency> 
    ... 
</dependencies> 

，這裏是拋出的錯誤：

您必須完全限定所有XML元素：

<beans:bean id="contextSource" class="org.springframework.security.ldap.DefaultSpringSecurityContextSource"> 
    <beans:constructor-arg value="ldap://localhost:389/dc=mydomain,dc=com" /> 
    <beans:property name="userDn" value="cn=manager,dc=mydomain,dc=com" /> 
    <beans:property name="password" value="password" /> 
</beans:bean> 

as beans不是默認名稱空間。既然你從來沒有在您的程式碼中使用默認的Spring Security命名空間，只是讓beans一個默認：

<beans xmlns="http://www.springframework.org/schema/beans" 

，並宣佈豆類如常。
