JDBC插入資料，更新資料，使用NamedParameterJdbcTemplate物件直接操作javaBean
原來如此簡單：
DButil:
public NamedParameterJdbcTemplate getNamedParameterJdbcTemplate() {
if (nam == null) {
synchronized(DBUtil.class){
if (nam==null) {
//呼叫NamedParameterJdbcTemplate都為update操作，資料來源必須為主庫
nam = new NamedParameterJdbcTemplate(masterDBDataSource);
}
}
}
return nam;
}
Dao:
@Autowired
private DBUtil dbUtil;
public int add(ProviderInfoEntity providerInfoEntity) throws DataAccessException, UnsupportedEncodingException {
String insertsql =
"insert into RM_ProviderInfo (ProviderCode, ProviderName, ServiceCode, " +
"ServiceName, ResidueDegree, ExpireDate, Priority, Status, LastUpdateID, LastUpdateDate)"
+ " values (:ProviderCode, :ProviderName, :ServiceCode, :ServiceName, :ResidueDegree, :ExpireDate, :Priority, :Status, :LastUpdateID, :LastUpdateDate)";
SqlParameterSource sps = new BeanPropertySqlParameterSource(providerInfoEntity);
return dbUtil.getNamedParameterJdbcTemplate().update(insertsql, sps);
}
結束
另外，沒有主從配置的資料庫，請參考下面程式碼：更簡潔
public int add(Entity entity) throws DataAccessException, UnsupportedEncodingException {
String insertsql =
"insert into RM_ProviderInfo (ProviderCode, ProviderName, ServiceCode, ServiceName, ResidueDegree, ExpireDate, Priority, Status, LastUpdateID, LastUpdateDate) values (:ProviderCode, :ProviderName, :ServiceCode, :ServiceName, :ResidueDegree, :ExpireDate, :Priority, :Status, :LastUpdateID, :LastUpdateDate)";
SqlParameterSource sps = new BeanPropertySqlParameterSource(entity);
//下面的dataSource可從JdbcTemplate物件中獲取得到
NamedParameterJdbcTemplate npjt = new NamedParameterJdbcTemplate(dataSource);
return npjt.update(insertsql, sps);
}
