首先简单的说明一下SysBillManage，它的功能是根据传递参数分配单据号，并且实现自增。比如是出库通知单，那么参数是OUT_DO_INFORM_ORDER，那么得到的结果是OutB0000001这样的形式的单据号，每一次增加出库通知单则单据号增1，既是OutB0000002。其中参数OUT_DO_INFORM_ORDER对应于数据库SysBillManage表中的一条记录的ID。
在用silkperformer 6.5做压力测试的时候，则出现一下异常，测试用例就是并发生成出库通知单：

看到这个错误，就想到可能是代码没有同步，但是事实上代码已经做了简单的同步。
在SysBillManageServiceImpl中，既是service的实现代码，其中getOrderNO(String billsort)是获得单据号的方法。
private SysBillManageDAO sysbillmanagedao;
private SysBillManage sysbillmanage;
//...其他处理
public synchronized String getOrderNO(String billsort) {
if (sysbillmanagedao.findById(billsort) != null) {
this.sysbillmanage = sysbillmanagedao.findById(billsort);
int currentnumber = Integer.parseInt(sysbillmanage
.getCurrentNumber());
currentnumber++;
String factcurrentnumber = "" + currentnumber;
String billtypeprefix = sysbillmanage.getTypePrefix();
String billcodeformat = sysbillmanage.getCodeFormat();
String factbillcodeformat = leftAppend(billcodeformat,
factcurrentnumber);
sysbillmanage.setCurrentNumber(factcurrentnumber);
this.save(sysbillmanage);
return billtypeprefix + factbillcodeformat;
} else {
sysbillmanage = new SysBillManage();
sysbillmanage.setBillType(billsort);
sysbillmanage.setTypePrefix(this.getbillprefix(billsort));
sysbillmanage.setStartNumber("1");
sysbillmanage.setCurrentNumber("1");
sysbillmanage.setCodeFormat("0000000");
sysbillmanage.setRemark("");
this.save(sysbillmanage);
String factcurrentnumber = sysbillmanage.getCurrentNumber();
String billcodeformat = sysbillmanage.getCodeFormat();
String factbillcodeformat = leftAppend(billcodeformat,
factcurrentnumber);
return this.getbillprefix(billsort) + factbillcodeformat;
}
}
