我正在 tomcat 7 中开发网站(spring 3.1.1)，但出现错误

这是我的 SqlMapConfig.xml、applicationContext 和我的根上下文。

配置就是配置，尝试去google一下。 它看起来像下面这样
<configuration>
<settings>
<setting name="cacheEnabled" value="true" />
<setting name="multipleResultSetsEnabled" value="true" />
<setting name="useColumnLabel" value="true" />
<setting name="useGeneratedKeys" value="false" />
<setting name="defaultExecutorType" value="SIMPLE" />
<setting name="defaultStatementTimeout" value="25000" />
<setting name="jdbcTypeForNull" value="NULL" />
</settings>
<typeAliases>
</typeAliases>
</configuration>
并再次检查您的 sqlSessionFactory bean 配置
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:/configuration/mybatis-config.xml"/>
<property name="mapperLocations" value="classpath*:sample/config/mappers/**/*.xml" />
</bean>
我认为，这就是构建失败的原因。
关于java - 错误: org. springframework.web.context.ContextLoader - 上下文初始化失败org.springframework.beans.factory.BeanCreationException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32642310/
