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;
}
主要问题是没有 ScopedProxyMode，它使用接口并在稍后在作业中尝试使用 bean 时崩溃。但是当我添加范围时，它会在尝试访问作业执行上下文时爆炸。那么我怎样才能用这个 bean 实现这两件事呢？
更新我更改为 @JobScope 并且上下文没有问题，但是在尝试实例化 bean 并打开数据库时出现此异常。
