1.插入一條記錄返回剛插入記錄的id

1. public int addBean(final Bean b){  
2.         final String strSql = "insert into buy(id,c,s,remark,line,cdatetime," +  
3.                 "c_id,a_id,count,type) values(null,?,?,?,?,?,?,?,?,?)";  
4.         KeyHolder keyHolder = new GeneratedKeyHolder();  
5.         this.getJdbcTemplate().update(  
6.                 new PreparedStatementCreator(){  
7.                     public java.sql.PreparedStatement createPreparedStatement(Connection conn) throws SQLException{  
8.                         int i = 0;  
9.                         java.sql.PreparedStatement ps = conn.prepareStatement(strSql);   
10.                         ps = conn.prepareStatement(strSql, Statement.RETURN_GENERATED_KEYS);  
11.                         ps.setString(++i, b.getC());  
12.                         ps.setInt(++i,b.getS() );  
13.                         ps.setString(++i,b.getR() );  
14.                         ps.setString(++i,b.getline() );  
15.                         ps.setString(++i,b.getCDatetime() );  
16.                         ps.setInt(++i,b.getCId() );  
17.                         ps.setInt(++i,b.getAId());  
18.                         ps.setInt(++i,b.getCount());  
19.                         ps.setInt(++i,b.getType());  
20.                         return ps;  
21.                     }  
22.                 },  
23.                 keyHolder);  
24.         return keyHolder.getKey().intValue();  
25.     }  

 2.批量插入資料

1. public void addBuyBean(List<BuyBean> list)   
2.     {   
3.        final List<BuyBean> tempBpplist = list;   
4.        String sql="insert into buy_bean(id,bid,pid,s,datetime,mark,count)" +  
5.             " values(null,?,?,?,?,?,?)";   
6.        this.getJdbcTemplate().batchUpdate(sql,new BatchPreparedStatementSetter() {  
7.             @Override  
8.             public int getBatchSize() {  
9.                  return tempBpplist.size();   
10.             }  
11.             @Override  
12.             public void setValues(PreparedStatement ps, int i)  
13.                     throws SQLException {  
14.                   ps.setInt(1, tempBpplist.get(i).getBId());   
15.                   ps.setInt(2, tempBpplist.get(i).getPId());   
16.                   ps.setInt(3, tempBpplist.get(i).getS());   
17.                   ps.setString(4, tempBpplist.get(i).getDatetime());   
18.                   ps.setString(5, tempBpplist.get(i).getMark());                   
19.                   ps.setInt(6, tempBpplist.get(i).getCount());  
20.             }   
21.       });   
22.     }  

 3.批量插入並返回批量id

注：由於JDBCTemplate不支援批量插入後返回批量id，所以此處使用jdbc原生的方法實現此功能

1. public List<Integer> addProduct(List<ProductBean> expList) throws SQLException {  
2.        final List<ProductBean> tempexpList = expList;  
3.        String sql="insert into product(id,s_id,status,datetime,"  
4.             + " count,o_id,reasons"  
5.             + " values(null,?,?,?,?,?,?)";  
6.        DbOperation dbOp = new DbOperation();  
7.        dbOp.init();  
8.        Connection con = dbOp.getConn();  
9.        con.setAutoCommit(false);  
10.        PreparedStatement pstmt = con.prepareStatement(sql, PreparedStatement.RETURN_GENERATED_KEYS);  
11.        for (ProductBean n : tempexpList) {  
12.            pstmt.setInt(1,n.getSId());     
13.            pstmt.setInt(2,n.getStatus());   
14.            pstmt.setString(3,n.getDatetime());   
15.            pstmt.setInt(4,n.getCount());  
16.            pstmt.setInt(5,n.getOId());  
17.            pstmt.setInt(6,n.getReasons());  
18.            pstmt.addBatch();  
19.        }  
20.        pstmt.executeBatch();   
21.        con.commit();     
22.        ResultSet rs = pstmt.getGeneratedKeys(); //獲取結果  
23.        List<Integer> list = new ArrayList<Integer>();   
24.        while(rs.next()) {  
25.            list.add(rs.getInt(1));//取得ID  
26.        }  
27.        con.close();  
28.        pstmt.close();  
29.        rs.close();  
30.        return list;  
31. }  

以上三組程式碼直接複製把對應的實體類名一改就可以直接使用在專案中，希望對大家有幫助
