本文分析了在Spring Boot项目中使用MyBatis时遇到的Mapper注入失败问题，探讨了原因在于自动配置冲突及数据源设置缺失，并提供了解决方案，包括正确配置数据源和调整@SpringBootApplication注解的exclude属性。

开始，加了这个注解，一定不要加这段代码 这个注解是排除自动注入 导致mapper注入不进去。

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'areaDicMapper' defined in file [/home/tongning/ideaprojects/foooooot/dao/target/classes/com/travel/dao/areadic/AreaDicMapper.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required
 

 

原来是没有在application.properties中加spring.datasource的属性报下面的错。

但是奇怪的是我另外一个模块没有加，不会报错。（用的是Bean注入的c3p0）。那么我用了内置的，c3p0就失效了。等找到解决办法再编辑吧。

 

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).
