如何解决spring没有定义名为’dataSource’的bean？

2019年8月4日 465次阅读

我的’dataSource’bean在dao-context.xml中定义,就像这样

<bean name="hcpDS" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" >
                <property name="driverClassName" value="${hcp.connection.driver_class}" />
                <property name="username" value="${hcp.connection.username}" />
                <property name="password" value="${hcp.connection.password}" />
                <property name="url" value="${hcp.connection.url}" />
                <property name="maxIdle" value="${hcp.minPoolSize}" />
                <property name="maxActive" value="${hcp.maxPoolSize}" />
            </bean>

在security-context.xml中我试图像这样使用它：

<beans:bean class="org.springframework.security.core.userdetails.jdbc.JdbcDaoImpl" id="userDetailsService">
        <beans:property name="rolePrefix" value="ROLE_"/>
        <beans:property name="dataSource" ref="dataSource"/>
        <beans:property name="usersByUsernameQuery" value="SELECT username,password,enabled FROM Users WHERE username = ?"/>
        <beans:property name="authoritiesByUsernameQuery" value="SELECT u.username, a.authorityname FROM Users u JOIN Users_Authorities ua on u.id = ua.user_id JOIN Authorities a on ua.authorities_id = a.id WHERE u.username = ?"/>
    </beans:bean>

并且在日志中有错误：

2014-06-08 16:10:06,683 ERROR [localhost-startStop-1] ContextLoader - Context initialization failed

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authentication.ProviderManager#0': Cannot create inner bean '(inner bean)' of type [org.springframework.security.config.authentication.AuthenticationManagerFactoryBean] while setting bean property 'parent'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authenticationManager': Cannot resolve reference to bean 'org.springframework.security.authentication.dao.DaoAuthenticationProvider#0' while setting bean property 'providers' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authentication.dao.DaoAuthenticationProvider#0': Cannot resolve reference to bean 'userDetailsService' while setting bean property 'userDetailsService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDetailsService' defined in class path resource [HCP-security-context.xml]: 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

这是WEB-INF文件夹中的applicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>

最佳答案 使用name =“dataSource”重命名数据源bean id,并且必须在security-context.xml中导入dao-context.xml才能使用dataSource bean.
