SimpleJdbcInsert无法定位表“user_models”的列，因此无法生成insert语句

Question

我收到了这个错误

Unable to locate columns for table 'user_models' so an insert statement can't be generated

使用Spring3.1.2。我正在维护一个遗留代码。并且它(抛出异常的方法)有注释@Transactional(propagation = Propagation.REQUIRED)。另外，它正在使用缓存，并且有下面的注释@CacheEvict(value = "UserModel", key = "#userModel.id") --我在这个异常上碰到了死胡同。我只找到了一个关于这个错误的链接：https://jira.spring.io/browse/SPR-4782，我无法理解它。至少有人能指引我走向正确的方向。

堆栈跟踪如下：

在下面抛出错误的代码片段：

Map<String, Object> args = ImmutableMap.<String, Object>builder()
                .put(ID_COL, modelId)
                .put(ORG_ID_COL, orgId)
                .put(NAME_COL, name)
                .put(SCORES_TABLE_NAME_COL, scoresTableName)
                .put(TARGET_TABLE_NAME_COL, targetTableName)
                .put(ATTRIB_JSON_COL, attributes)
                .build();

        if (insert) {
            insert().withTableName(TABLE).execute(args);
            userModel.setId(modelId);

上面这个是DaoImpl。表的值在Dao之上的层中声明为

公共静态最终字符串表= "user_models"；

Answer 1

我也犯过同样的错误。结果发现问题是表名上的错误。再次检查您是否正确地键入了表名。

Answer 2

我们也犯了同样的错误。

我们的'tableName‘是另一个模式中的表的同义词。

但是关于https://jira.spring.io/browse/SPR-4782，默认情况下，Oracle连接配置为"includeSynonyms“= false。

试试这个来解决这个问题：

new SimpleJdbcInsert(datasource)
.includeSynonymsForTableColumnMetaData()
.withTableName("tableName");

此外，我们还有pooledConnections，因此为了处理这个问题，我们必须指定本地jdbc提取器：

new SimpleJdbcInsert(datasource)
.useNativeJdbcExtractorForNetaData(new OracleJdbc4NativeJdbcExtractor())
.includeSynonymsForTableColumnMetaData()
.withTableName("tableName");

Answer 3

除了表名之外，还需要指定列：

String[] columns = {"column1","column2"}

SimpleJdbcInsert jdbcInsert = new SimpleJdbcInsert(dataSource)
                .usingColumns(columns)
                .withTableName(table);
