java - SimpleJdbcInsert 无法定位表 'user_models' 的列，因此无法生成插入语句

Question

我收到此错误

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

使用Spring 3.1.2。我正在维护遗留代码。并且它(抛出异常的方法)具有注释@Transactional(propagation = Propagation.REQUIRED)。它还使用缓存并具有以下注释 @CacheEvict(value = "UserModel", key = "#userModel.id") 我在这个异常上遇到了死胡同。我只找到了一个关于此错误的链接: https://jira.spring.io/browse/SPR-4782 我无法理解它的意义。有人至少可以引导我走向正确的方向吗？

堆栈跟踪如下:

抛出以下错误的代码片段:

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);

上面是DaoImpl。 TABLE 的值在 Dao 之上的层中声明为

public static final String TABLE = "user_models";

Answer 1

我们遇到了同样的错误。

我们的“tableName”是另一个架构中的表的同义词。

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

尝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 native jdbc 提取器:

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