spring我可以在Java注释中使用ScopedProxy模式时访问JobExecutionContext吗

Question

我正在尝试创建一个bean，但遇到了一些问题。这是我目前的配置

    @Bean(name = TDA_JDBC_CURSOR_ITEM_READER)
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public TdaJdbcCursorItemReader<PostDatedAchIn> tdaJdbcCursorItemReader(@Value("#{jobExecutionContext['current.business.date']}") final String currentBusinessDate) {

    SqlStatementHelper sqlStatementHelper = new SqlStatementHelper(PostDatedAchInConstants.POST_DATED_ACH_IN_PROPERTY_FILE,
            PostDatedAchInConstants.POST_DATED_ACH_IN_PROPERTY_ALT_FILE);
    String sqlStatement = sqlStatementHelper.getSqlStatement(PostDatedAchInConstants.RETRIEVE_POST_DATED_ACH_IN);

    TdaJdbcCursorItemReader<PostDatedAchIn> tdaJdbcCursorItemReader = new TdaJdbcCursorItemReader<PostDatedAchIn>();

    tdaJdbcCursorItemReader.setDataSource(prodDataSource);
    tdaJdbcCursorItemReader.setSql(sqlStatement);
    tdaJdbcCursorItemReader.setRowMapper(new PostDatedAchInRowMapper());

    ArrayList<String> parameters = new ArrayList<String>();
    parameters.add(currentBusinessDate);
    parameters.add(currentBusinessDate);
    parameters.add(currentBusinessDate);

    ListPreparedStatementSetter preparedStatementSetter = new ListPreparedStatementSetter();
    preparedStatementSetter.setParameters(parameters);
    tdaJdbcCursorItemReader.setPreparedStatementSetter(preparedStatementSetter);

    return tdaJdbcCursorItemReader;
}

主要问题是，如果没有ScopedProxy模式，它将使用接口，并在稍后的作业中尝试使用bean时崩溃。但当我添加作用域时，当试图访问jobexecutioncontext时，它就会崩溃。那么我如何用这个豆子实现这两个目标呢

更新我改为@JobScope，上下文没有问题，但是当它试图实例化bean并打开数据库时，会出现这个异常
