Question

我正在尝试创建一个bean，但是我收到了一个错误。我已经将它缩小到这个特定的bean并且在引用API documents 之后，我不明白为什么每当我部署我的.war文件时它都会被抛出。希望我错过了一些简单的东西。

这是app-security.xml内容：

<?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>

以下是我的maven pom.xml的片段：

<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>

    </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>

这是抛出的错误：

您必须完全限定所有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>

因为beans不是默认命名空间。由于您从未在代码段中使用默认的Spring Security命名空间，因此只需将beans设为默认名称：

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

并像往常一样宣布bean。
