ssm框架搭建遇到的问题

1. 严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.mybatis.spring.mapper.MapperScannerConfigurer#0' defined in class path resource [spring-context.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.String' to required type 'org.apache.ibatis.session.SqlSessionFactory' for property 'sqlSessionFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [org.apache.ibatis.session.SqlSessionFactory] for property 'sqlSessionFactory': no matching editors or conversion strategy found

 

 原因：sessionFactory的name和value的值一样  解决办法：name值改变一下就可以。

 

2. java.lang.NoClassDefFoundError: org/aspectj/weaver/tools/PointcutDesignatorHandler

问题描述：缺少org.aspectj.weaver.jar架包

描述：jdbc.properties书写遵循的原则是key-value的格式，在spring配置文件中引用时，应和=前的写法保持一致

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [spring-context.xml]: Invocation of init method failed; nested exception is java.sql.SQLException: Unknown system variable 'tx_isolation'

原因：数据库连接jar版本太低
