写这个博客的作用主要是给自己涨涨记性，以后像这种低级的错误最好不要再犯。
先看一下报错的日志：

从报错日志上面看，这个错误已经很明显了，在执行向LPDebitNote表中插入数据的时候报主键冲突。从SQL语句中看，确实是这样的。
在看一下自己之前写的代码：
其实在最上面还有一行：LPDebitNoteSchema tLPDebitNoteSchema = new LPDebitNoteSchema();
现在不难看出是因为给mlpdebitnotese集合中添加了两个相同的tLPDebitNoteSchema 对象，而且都是最后一次循环的那个对象。
改正之后的代码：
1 SQLwithBindVariables sqlbv = new SQLwithBindVariables(); 2 String tSql = "SELECT * FROM LCDebitNoteDet WHERE PolicyNo='?PolicyNo?' "; 3 sqlbv = new SQLwithBindVariables(); 4 sqlbv.sql(tSql); 5 sqlbv.put("PolicyNo", mLPEdorAppSchema.getPolicyNo()); 6 tLCDebitNoteDetSet = tLCDebitNoteDetDB.executeQuery(sqlbv); 7 //在LCDEBITNOTEDET表里面一个保单号能有多个DEBITNOTENO 8 if(tLCDebitNoteDetSet!=null&&tLCDebitNoteDetSet.size()>0){ 9 for (int i = 1; i <=tLCDebitNoteDetSet.size() ; i++) { 10 LPDebitNoteSchema tLPDebitNoteSchema = new LPDebitNoteSchema(); 11 SQLwithBindVariables sqlbv1 = new SQLwithBindVariables(); 12 String tSql1 = "SELECT * FROM LCDebitNote WHERE DebitNoteNo='?DebitNoteNo?' "; 13 sqlbv1 = new SQLwithBindVariables(); 14 sqlbv1.sql(tSql1); 15 sqlbv1.put("DebitNoteNo", tLCDebitNoteDetSet.get(i).getDebitNoteNo()); 16 tLCDebitNoteSet = tLCDebitNoteDB.executeQuery(sqlbv1); 17 if (tLCDebitNoteSet != null && tLCDebitNoteSet.size() > 0) { 18 tLCDebitNoteSchema = tLCDebitNoteSet.get(1); 19 this.mReflections.transFields(tLPDebitNoteSchema, tLCDebitNoteSchema); 20 tLPDebitNoteSchema.setEdorNo(mEdorNo); 21 tLPDebitNoteSchema.setEdorCode(mLPEdorAppSchema.getEdorCode()); 22 // tLPDebitNoteSchema.setSelfPayOffState("02");签发的时候在进行状态的改变 23 // tLPDebitNoteSchema.setVerificationDate(mCurrentDate); 24 tLPDebitNoteSchema.setOperator(mG.Operator); 25 tLPDebitNoteSchema.setMakeDate(mCurrentDate); 26 tLPDebitNoteSchema.setMakeTime(mCurrentTime); 27 tLPDebitNoteSchema.setModifyDate(mCurrentDate); 28 tLPDebitNoteSchema.setModifyTime(mCurrentTime); 29 //mMap.put(tLPDebitNoteSchema,"DELETE&INSERT"); 30 } 31 mLPDebitNoteSet.add(tLPDebitNoteSchema); 32 } 33 mMap.put(mLPDebitNoteSet,"DELETE&INSERT"); 34 }
这次就能完美运行了，不会报主键冲突了。
