然后就是代码：
Mapper部分：
BooksMapper.xml

INSERT INTO

update

where bid = #{bid}
delete
from
where bid = #{bid}

POJO实体
Bookadmin.java

service部分
BooksService.java

最近mysql数据库经常死掉，用命令net stop mysql命令也无法停掉，关闭Tomcat的时候，出现Waiting for N instance(s) to be deallocated 信息。查了下，大概就是程序没有对数据库连接释放，导致Connection泄露了。因为用的是开元集成的平台，内部程序也不可能一下子给改掉的，就验证一下咯。启动Tomcat,用户登录系统，用netstat -
var a=document.getElementsByClassName('textinput');
var b=[];
for(var m=0;m<a.length;m++){
if(a[m].getAttribute('placeholder')!=null)
b.push(a[m])
}
var l
错误信息：
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cartService': Scope 'session' is not active for the current thread; consider defining a scoped
这个开源软件包是国内的一位高手自行研制开发的，正如他所说的一样，我觉得它可以使一个工作流引擎上一个台阶。。。。。。欢迎大家使用，并提出意见和建议。。。

关键字：Oracle实现类split函数的方
项目里需要保存结构数据，批量传到后他进行保存，为了减小数据量，子集拼装的格式，使用存储过程进行保存。保存的过程中需要对数据解析。但是oracle没有Java中split类似的函数。从网上找了一个，也补全了一下。
CREATE OR REPLACE TYPE t_split_100 IS TABLE OF VARCHAR2(100);
