Question

我的'dataSource'bean是在dao-context.xml中定义的，就像这个

一样

<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中的

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>

日志中有错误：

Answer 1

使用name="dataSource"重命名数据源bean id，并且import dao-context.xml内必须security-context.xml才能使用dataSource bean。

Answer 2

DataSource bean的名称似乎不正确。将name="hcpDS"替换为name="dataSource"。

如何解决spring没有定义名为'dataSource'的bean？
