如何从基于 Java 的 Web 服务调用具有日期输入的 Oracle 过程？

Question

现在我有一个带有 IN 和 OUT 参数的 Oracle 存储过程。 IN 参数是简单类型和集合（customType 作为 customObject 的表）。 OUT 参数是 REFCURSOR 和一些 varchar。问题是：当我将一些数据格式的字符串发送到 Date IN 参数时，它会向我抛出以下问题：

java.lang.IllegalArgumentException: Timestamp format must be yyyy-mm-dd hh:mm:ss[.fffffffff]
        at java.sql.Timestamp.valueOf(Timestamp.java:185)
        at oracle.sql.DATE.toBytes(DATE.java:720)
        at oracle.sql.DATE.<init>(DATE.java:222)
        at oracle.jdbc.oracore.OracleTypeDATE.toDatum(OracleTypeDATE.java:66)
        at oracle.sql.StructDescriptor.toOracleArray(StructDescriptor.java:717)
        at oracle.sql.StructDescriptor.toArray(StructDescriptor.java:1375)
        at oracle.sql.STRUCT.<init>(STRUCT.java:159)
        at oracle.sql.OracleSQLOutput.getSTRUCT(OracleSQLOutput.java:114)
        at oracle.sql.STRUCT.toSTRUCT(STRUCT.java:524)
        at oracle.jdbc.oracore.OracleTypeADT.toDatum(OracleTypeADT.java:227)

        at oracle.sql.ARRAY.<init>(ARRAY.java:152)
        ...

问题是：我应该如何将 Date IN 参数发送到 Oracle？

对象、集合和过程本身如下：

create or replace type fd_customTypeObj1 is table of fd_customType1;

create or replace type fd_customType1 is object (
valorCuota_Inic               number,
fecpagoCuota_Inic             date
);

create or replace type fd_customTypeObj2 is table of fd_customType2;

create or replace type fd_customType2 is object (

：支持oracle对象，请求和响应也存在。 提前致谢！

编辑 28/12/2009：按照建议，我在 WS 类中完成了此操作：

(...)
cn = DriverManager.getConnection( <that_URL>, <that_user>, <that_pwd> );
OracleCallableStatement callStatement = null;
DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
Date setDate = new Date(0);
long dateTime = 0;
java.sql.Date sqlDate = new java.sql.Date(0);

ConceptosAdicionales conceptosObject1 = new ConceptosAdicionales();
conceptosObject1.setCod_tpOper("A1");
conceptosObject1.setValorCpto(1000); 
setDate = (Date) df.parse("29/12/2009");
dateTime = setDate.getTime(  );
sqlDate = new java.sql.Date( dateTime );
conceptosObject1.setFecpagoCpto(sqlDate);
(...)

这种设置日期的方法可以与任何其他日期参数一起复制。 ConceptosAdicionales 类现在具有 java.sql.Date 属性，而不是字符串。区分 java.util.Date 和 sql 很重​​要。我使用此参考按照此处所示的方式进行转换。希望这对这里的人有帮助。谢谢大家

Answer 1

考虑重构代码以将日期处理为 java.sql.Date 对象而不是字符串。这将允许您调用 setDate(....) 而不是 setString(...)，并使您的代码更简洁。

Answer 2

让 Web 服务将字符串绑定到日期，然后再将其传回。您想要这样做，因为它将验证正确的格式和类型。绑定和验证对于避免 SQL 注入也是必要的。
