如果提示无法注入依赖，就考虑没有引用哪个工程，对于war包来说要全部引用，举个栗子：
<?xml version="1.0"?> <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>tms</groupId> <artifactId>tms-parent</artifactId> <version>1.0.0</version> </parent> <artifactId>tms-yinliu</artifactId> <name>tms-yinliu</name> <dependencies> <dependency> <artifactId>tms-util</artifactId> <groupId>tms</groupId> <version>1.0.0</version> </dependency> <dependency> <artifactId>tms-api</artifactId> <groupId>tms</groupId> <version>1.0.0</version> </dependency> </dependencies> </project>
对于这样的没有war包的分布式，你只需引用你所需要的工程。

<!-- 注解驱动 -->
<mvc:annotation-driven/>
<!-- 自动扫描的包 -->
<context:component-scan base-package="com.pyq.weixin"/>
3. 特别对于mapper层，需要注意一个问题，mybatis中对应的mapper接口无法注入，原因可能是没有扫描到此mapper
<!--错误的 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.pyq.weixin.mapper" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- 正确的扫描mapper（dao）包 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.pyq.**.mapper" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean>
由于一个项目中的mapper层不止一个，所以需要扫描到所有的mapper层，需要用到通配符 com.pyq.**.mapper指的是pyq下面所有的mapper层
