今天解决了eclipse内存溢出的问题，运行的时候没有问题但是 会爆出一下的问题，一开始没有把他当成错误，最后果然还是有问题，下面就来描述一下解决问题的方法
Exception in thread "http-bio-8080-exec-2"在eclipse代码的空白处点击右键，按照下图选择
然后在下图位置输入参数，这样再次运行就可以了；
-Xms256m -Xmx512m -XX:MaxNewSize=256m -XX:MaxPermSize=256m常用的链接语句和授权语句要准备更好
sqlplus scott/tiger@192.168.177.128:1521/orcl //远程链接服务器的数据库 sqlplus sys/任意值 as sysdba //本地链接超级管理员 grant SELECT ANY DICTIONARY to scott;//超级管理员的授权配置plsql的TNS环境变量
划分为utils、exception、dao、service、web、parent、domain七大模块
utils模块：单独的一个子模块
domain模块：注意实体类和他的映射文件相对位置
dao模块：持久层的一些交互处理，注意配置文件只有---applicationContext-dao.xml---这一个文件内容是
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> //Spring的分层管理，有什么类写对应的bean工厂，其余的放在web层 <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="dataSource"></property> <bean id="baseDao" class="com.chuantao.jk.daoImp.BaseDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> </beans>service模块:初始化比较简单，但是要注意 pom文件继承以上两个 和 exception 三个jar包
web模块：最为复杂，需要注意的点：web.xml文件 注意顺序内容为：
