[英]cvc-elt.1: Cannot find the declaration of element 'beans'
我正在尝试获取一个 bean 对象以使用 Spring Security 对用户登录功能进行身份验证:
ApplicationContext context = new ClassPathXmlApplicationContext(
"com/humandevice/drive/fx/util/applicationContext.xml");
authenticationManager = (AuthenticationManager) context
.getBean("authenticationManager");
我的applicationContext.xml
如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/security"
xmlns:beans="http://www.springframework.org/schema/beans" 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/security
http://www.springframework.org/schema/security/spring-security-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd"
xmlns:context="http://www.springframework.org/schema/context">
<context:component-scan base-package="com.humandevice.drive.fx">
<context:include-filter type="regex"
expression="com.humandevice.drive.fx.*" />
</context:component-scan>
<bean id="LoginController" alias="loginController" class="controller.LoginController">
<property name="authenticationManager" ref="authenticationManager" />
<property name="applicationContext" ref="applicationContext" />
</bean>
<bean id="applicationContext" alias="applicationContext"
class="org.springframework.context.ApplicationContext;">
</bean>
<authentication-manager alias="authenticationManager">
<authentication-provider user-service-ref="userService">
<password-encoder ref="bCryptPasswordEncoder" />
</authentication-provider>
</authentication-manager>
</beans>
但我得到这个例外:
Caused by: org.xml.sax.SAXParseException; lineNumber: 9; columnNumber: 64; cvc-elt.1: Cannot find the declaration of element 'beans'.
我很难理解这个问题。
我对我的 XML 做了一些更改,如下所示:
<?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:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.2.xsd"> <import resource="/context-service.xml" /> <import resource="/context-repository.xml" /> <context:component-scan base-package="com.humandevice.drive.fx"></context:component-scan> <authentication-manager> <authentication-provider user-service-ref="com.humandevice.drive.service.user.IUserService"> <password-encoder ref="bCryptPasswordEncoder" /> </authentication-provider> </authentication-manager> </beans:beans>
我现在收到此异常:
lineNumber: 11; columnNumber: 44; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'import'.
您的默认命名空间是http://www.springframework.org/schema/security
并且您配置了xmlns:beans="http://www.springframework.org/schema/beans"
这意味着您必须添加前缀beans:
to所有标签形式http://www.springframework.org/schema/beans
所以你的 XML 应该如下。
<?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: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/security
http://www.springframework.org/schema/security/spring-security-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd"
xmlns:context="http://www.springframework.org/schema/context">
<context:component-scan base-package="com.humandevice.drive.fx">
<context:include-filter type="regex"
expression="com.humandevice.drive.fx.*" />
</context:component-scan>
<beans:bean id="LoginController" alias="loginController" class="controller.LoginController">
<beans:property name="authenticationManager" ref="authenticationManager" />
<beans:property name="applicationContext" ref="applicationContext" />
</beans:bean>
<beans:bean id="applicationContext" alias="applicationContext"
class="org.springframework.context.ApplicationContext;">
</beans:bean>
<authentication-manager alias="authenticationManager">
<authentication-provider user-service-ref="userService">
<password-encoder ref="bCryptPasswordEncoder" />
</authentication-provider>
</authentication-manager>
</beans:beans>
此代码将帮助您。

对我来说,我只是在同一个地方剪切、粘贴和保存 XML 文件,它对我有用!!
我有类似的问题,我想再举一个可能原因的例子。
原始 .xml
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="https://www.springframework.org/schema/mvc"
xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xmlns:beans="https://www.springframework.org/schema/beans"
xmlns:context="https://www.springframework.org/schema/context" xmlns:tx="https://www.springframework.org/schema/tx"
xsi:schemaLocation="https://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd
https://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans.xsd
https://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd
https://www.springframework.org/schema/tx https://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
工作.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans

解决方案:
xmlns="http://www.springframework.org/schema/beans"
作为基础 xmlns。 删除beans:
前缀https
更改为http
对我来说,对 applicationContext.xml 的更改没有在类路径中更新。 所以我从类路径中手动删除了 applicationContext.xml 文件并重新构建了解决我问题的应用程序
我完全不确定为什么会有这种奇怪的行为。 我也面临同样的例外,并遵循Karthikeyan Vaithilingam
建议。 但问题仍然没有解决。 所以我已经恢复了我所做的更改并保存了文件。 中提琴!! 异常消失,现在没有错误。
我在尝试创建可执行 jar 时遇到了同样的错误。 我有
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:context.xml");
而不是(注意类路径后的 *)
ApplicationContext context = new ClassPathXmlApplicationContext("classpath*:context.xml");
