有人能告诉我如何摆脱这个错误吗，我做了很多尝试，但都无法传递错误，我是spring batch的新手，如果你能发布工作代码，那将非常有帮助，因为我在stackoverflow中看到了其他解决方案，但由于信息不完整，这些解决方案没有帮助。

Spring批处理不支持Informix。

这是支持的数据库列表：

public enum DatabaseType {
    DERBY("Apache Derby"),
    DB2("DB2"),
    DB2VSE("DB2VSE"),
    DB2ZOS("DB2ZOS"),
    DB2AS400("DB2AS400"),
    HSQL("HSQL Database Engine"),
    SQLSERVER("Microsoft SQL Server"),
    MYSQL("MySQL"),
    ORACLE("Oracle"),
    POSTGRES("PostgreSQL"),
    SYBASE("Sybase"),
    H2("H2"),
    SQLITE("SQLite");
}
