Question

我正在尝试从SimpleJdbcCall's execute()方法（即executing stored procedure in Spring）执行过程，但由于我的包名称中有双引号，因此它会出错："_test_package"。错误说，即使程序确实存在，也要声明程序。

我在Oracle中有以下程序包 -

Package Spec :-
CREATE OR REPLACE package GOVINDS."_test_package" is

    procedure createHelloMessage(namemsg in out VARCHAR2);

end "_test_package";

Package Body :-
CREATE OR REPLACE package body GOVINDS."_test_package" is

    procedure createHelloMessage(namemsg in out VARCHAR2) is
    begin
        namemsg := 'Hello '|| namemsg;
    end createHelloMessage;

end "_test_package";

我试图从Spring的SimpleJdbcCall中执行它，如下所示，但是它会出现错误，因为 PLS-00201：必须声明标识符'GOVINDS._TEST_PACKAGE'。

SimpleJdbcCall simpleJdbcCallObject =
    new SimpleJdbcCall(jdbcTemplate).withSchemaName("GOVINDS").withCatalogName("\"_test_package\"").withProcedureName("createHelloMessage")
        .withoutProcedureColumnMetaDataAccess()
        .withNamedBinding()
        .declareParameters(new SqlParameter("namemsg", OracleTypes.VARCHAR));

SqlParameterSource in = new MapSqlParameterSource().addValue("namemsg", "Jim", OracleTypes.VARCHAR);

Map<String, Object> out = simpleJdbcCallObject.execute(in);

错误stackstrace：

如果我尝试使用jdbcTemplate.call()执行，它可以正常工作。我更喜欢SimpleJdbcCall.execute（），因为为了保持一致性，我不想更改95-97％的代码。

Answer 1

这是因为双引号字符串区分大小写，一些Spring JDBC将您的字符串转换为大写，但实际的过程名称是小例。尝试将程序名称更改为大写，您的代码应该运行。

Answer 2

问题是spring jdbc将调用语句字符串转换为大写（甚至对象名称以双引号提供），如果以双引号提供的package-name是区分大小写的。

解决方案可以为package-name创建同义词。

resolve: {
  root: [
    'node_modules',
    path.resolve('src') // Resolve on root first
  ], 
  alias: {
    config: 'src/assets/js/config', // this is a config folder
    js: 'src/assets/js'
  }
}
