我的春季3.2.4的webapp运行正常.但是当我启动它时,我将获得调试信息：

我不知道这些信息是什么意思.我使用c3p0作为我的dataSource,配置是：

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>/WEB-INF/config/jdbc.properties</value>
            </list>
        </property>
    </bean>

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverClassName}" />
        <property name="jdbcUrl" value="${jdbc.url}" />
        <property name="user" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="autoCommitOnClose" value="true"/>
        <property name="checkoutTimeout" value="${cpool.checkoutTimeout}"/>
        <property name="initialPoolSize" value="${cpool.minPoolSize}"/>
        <property name="minPoolSize" value="${cpool.minPoolSize}"/>
        <property name="maxPoolSize" value="${cpool.maxPoolSize}"/>
        <property name="maxIdleTime" value="${cpool.maxIdleTime}"/>
        <property name="acquireIncrement" value="${cpool.acquireIncrement}"/>
        <property name="maxIdleTimeExcessConnections" value="${cpool.maxIdleTimeExcessConnections}"/>
    </bean>

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <bean id="simpleJdbcTemplate" class="org.springframework.jdbc.core.simple.SimpleJdbcTemplate">
        <constructor-arg ref="jdbcTemplate" />
    </bean>

我找不到JNDI的用途.我已经搜索了一些关于这个例外的问题.但它们始终与@Profile或@Configuration相关联.我的代码中没有@Profile或@Configuration.

在我的bean类中,没有@Bean注释.这些信息与此相关吗？但是我不需要spring注入我的bean类.

解决方法:

如果您不使用任何配置文件或mbeans,只需将以下context-params添加到web.xml作为解决方法(技巧),希望有人可以提供比这个丑陋的解决方案更好的解决方案.

<context-param>  
    <param-name>spring.profiles.active</param-name>  
    <param-value>dev</param-value>  
</context-param>  
<context-param>  
    <param-name>spring.profiles.default</param-name>  
    <param-value>dev</param-value>  
</context-param>
<context-param>  
    <param-name>spring.liveBeansView.mbeanDomain</param-name>  
    <param-value>dev</param-value>  
</context-param>
