web容器启动时假死mybatis并不抛出异常的解决办法

package com.common.spring;
import java.io.IOException;

import org.apache.ibatis.executor.ErrorContext;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
public class FixedSqlSessionFactory extends SqlSessionFactoryBean{
    @Override
    protected SqlSessionFactory buildSqlSessionFactory() throws IOException {
        try {
            return super.buildSqlSessionFactory();
        }catch (Exception e){
            e.printStackTrace();
        }finally {
            ErrorContext.instance().reset();
        }
        return null;
    }
}

1.创建以上类

2.修改mybatis配置使用此类

<!--  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> -->
    <bean id="sqlSessionFactory" class="com.common.spring.FixedSqlSessionFactory">    
        <property name="dataSource"      ref="dataSource${debug}" />  
        <property name="configLocation"  value="classpath:config/sqlMapConfig.xml" />
        <property name="mapperLocations" value="classpath*:config/${db.name}/**/*.xml" />
        <property name="typeHandlersPackage" value="com.tx.core.mybatis.handler"></property>  
    </bean> 

3.在FixedSqlSessionFactory的catch中打断点,启动web容器等待异常.
