一直遇到一个问题：
Caused by: java.lang.ClassNotFoundException: com.android.model.MessageInfo$$EnhancerByCGLIB$$24615aa3 (no security manager: RMI class loader disabled)
后来才发现是mybatis的懒加载引起的问题，
<settings>
<setting name="cacheEnabled" value="true"/>
<setting name="lazyLoadingEnabled" value="true"/>
<setting name="defaultStatementTimeout" value="20000"/>
</settings>
设置成
<settings>
<setting name="cacheEnabled" value="true"/>
<setting name="lazyLoadingEnabled" value="false"/>
<setting name="defaultStatementTimeout" value="20000"/>
</settings>
