[英]Spring Security XML configuration can not find my dataSource beans definition
我的WEB-INF/web.xml
执行以下操作-
1)加载我的servlet上下文WEB-INF/spring-web-servlet.xml
2)加载我的spring安全配置文件WEB-INF/spring-security.xml
3)添加springSecurityFilterChain
过滤器以拦截传入的URL
web.xml
<!-- Load spring-web-service.xml Servlet Definition -->
<servlet>
<servlet-name>spring-web</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
<!-- Programmatically add the property sources for the current Spring Profile -->
<init-param>
<param-name>contextInitializerClasses</param-name>
<param-value>com.galapagos.context.CustomEnvironmentApplicationContextInitializer</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>spring-web</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- Loads Spring Security config file -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-security.xml</param-value>
</context-param>
<!-- Spring Security - Intercept incoming requests for authentication -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy
</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
spring-web-servlet.xml
servlet上下文实际上定义了连接到数据库的dataSource
bean(它还会预先加载属性)
...
<!-- Load Properties -->
<beans:bean
class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
</beans:bean>
<!-- Database / JDBC -->
<beans:bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<beans:property name="driverClassName" value="${jdbc.driverClassName}" />
<beans:property name="url" value="${jdbc.url}" />
<beans:property name="username" value="${jdbc.username}" />
<beans:property name="password" value="${jdbc.password}" />
</beans:bean>
...
spring-security.xml
问题是web.xml
调出的第二个文件(我的WEB-INF/spring-security.xml
文件)也使用数据库连接,因为它查找存储在数据库中的角色和凭证
<http auto-config="true" use-expressions="true">
<intercept-url pattern="/admin**" access="hasRole('ROLE_ADMIN')" />
<!-- access denied page -->
<access-denied-handler error-page="/403" />
<form-login
login-page="/login"
default-target-url="/"
authentication-failure-url="/login?error"
username-parameter="email"
password-parameter="password" />
<logout logout-success-url="/login?logout" />
<!-- enable csrf protection -->
<csrf/>
</http>
<!-- Select users and user_roles from database -->
<authentication-manager>
<authentication-provider>
<jdbc-user-service
data-source-ref="dataSource"
users-by-username-query="SELECT email, password FROM users WHERE email=?"
authorities-by-username-query="SELECT email, role FROM user_roles WHERE email=?" />
</authentication-provider>
</authentication-manager>
运行时出现错误-
Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dataSource' is defined
我最好的猜测是,因为dataSource
是在第一个XML配置( WEB-INF/spring-web-servlet.xml
)中定义的,因此无法在后一个XML配置( WEB-INF/spring-security.xml
)中使用。
这是正确的吗?
如果是的话,定义dataSource
bean的最佳方法是什么,以便所有单个XML文件都可以根据需要调用它? 我假设我可能会添加一些其他组件,这些组件有时也需要数据库访问。
谢谢!
在web.xml中尝试更改此设置
contextConfigLocation /WEB-INF/spring-security.xml,WEB-INF / spring-web-servlet.xml这将为您提供帮助。
