Maven Web項目配置Mybatis出現SqlSessionFactory錯誤的解決方案

一、錯誤現象

 

嚴重: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.mybatis.spring.mapper.MapperScannerConfigurer#0' defined in URL [file:/F:/Workspaces/.metadata/.me_tcat7/webapps/jade_admin/WEB-INF/classes/config/spring/applicationContext-resources.xml]: Cannot resolve reference to bean 'SqlSessionFactory' while setting bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'SqlSessionFactory' defined in URL [file:/F:/Workspaces/.metadata/.me_tcat7/webapps/jade_admin/WEB-INF/classes/config/spring/applicationContext-resources.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse config resource: class path resource [config/mybatis/configuration.xml]; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: org.apache.ibatis.builder.BuilderException: Error creating instance. Cause: java.lang.IllegalStateException: Cannot enable lazy loading because CGLIB is not available. Add CGLIB to your classpath.

二、解決方案

1 在pom.xml中加上reflectasm包，這個包可以提供映射機制。

 

<dependency>
    <groupId>com.esotericsoftware.reflectasm</groupId>
    <artifactId>reflectasm</artifactId>
    <version>1.09</version>
</dependency>

 

2 在/src/main/webapp/WEB-INF/lib/中添加cglib-3.1.jar
