我想知道Salesforce用于调用远程Web服务的invoke方法的参数.我有一个服务,我可以调用,但服务WSDL没有定义安全要求,所以我希望我可以手动添加该信息(服务使用通过Soap头传递的WS-Security).
这是我(我想)到目前为止所知道的:
WebServiceCallout.invoke(
Class servicePort, //Usually set to "this", contains httpheader info as well as ?
request_x, //Request object, defining schema, properties, and field order
response_map_x, //Response object, defining schema, properties, and field order
new String[]{
String endpoint, //Endpoint of the service
String ?, //what is this?
String methodSchema, //Schema for the request object?
String method, //Name of the request method?
String responseSchema, //Schema for the response object?
String response, //Name of the response object?
String responseClass} //Name of the …

我看到了一些可能性:
选项1:使用单行插入PreparedStatement并多次执行:
String insert = "Insert into foo(bar, baz) values (?, ?)";
PreparedStatement stmt = conn.prepareStatement(insert);
for(MyObject obj : someList) {
stmt.setString(1, obj.getBar());
stmt.setString(2, obj.getBaz());
stmt.execute();
}

选项2:构建Oracle INSERT ALL语句:
String insert = "INSERT ALL " +
"INTO foo(bar, baz), (?, ?) " +
"INTO foo(bar, baz), (?, ?) " +
"SELECT * FROM DUAL";
PreparedStatement stmt = conn.prepareStatement(insert);
int i=1;
for(MyObject obj : someList) {
stmt.setString(i++, obj.getBar());
stmt.setString(i++, obj.getBaz());
}
stmt.execute();

Run Code Online (Sandbox Code Playgroud) 我有免费版的Soap UI和几个不同的工作区.我想为Soap UI设置几个快捷方式,每个快捷方式包括一个启动参数,指示要加载的工作空间,但我找不到实际参数是做什么的.我查看了文档,我看到了一个事实,即有可用的启动参数,但我找不到它们的列出位置.
有没有办法做到这一点(类似于eclipse的"-data"参数)?
谢谢.
我需要加入从我的程序中动态检索的动态数字列表。行数不是固定的,使用的数字也不是固定的。
我没有找到比以下更好的方法来实现这一点(就我而言,临时表没有帮助):
select 111 as col1, 322 as col2 from dual
union all
select 3 as col1, 14 as col2 from dual
union all
select 56 as col1, 676 as col2 from dual;

有一个更好的方法吗?我看到有一个 connect by 语句可以返回多行,但我没有看到执行多行和多列的方法。
我有遗留代码,使用java.util.Date创建一个古老的日期(12月30日0002).我正在尝试更新我可以使用的代码,但这需要在Date和LocalDate等之间进行转换.我无法完全摆脱使用Date或古代日期选择.
我发现在Date和Instant之间来回转换这个古老的日期似乎是一个错误,并且希望有人可以解释发生了什么.
这是一个示例:
Date date = new Date();
Instant instant = date.toInstant();
System.out.println("Current:");
System.out.println("Date: "+date);
System.out.println("Instant: "+instant);
System.out.println("Date epoch: "+date.getTime());
System.out.println("Instant epoch: "+instant.getEpochSecond()*1000);
System.out.println("\nAncient from Date:");
Calendar cal = new GregorianCalendar(TimeZone.getTimeZone("MST"));
cal.set(2, Calendar.NOVEMBER, 30, 0, 0, 0);
date = cal.getTime();
instant = date.toInstant();
System.out.println("Date: "+date);
System.out.println("Instant: "+instant);
System.out.println("Date epoch: "+date.getTime());
System.out.println("Instant epoch: "+instant.getEpochSecond()*1000);
System.out.println("\nAncient from Instant:");
instant = Instant.parse("0002-11-30T00:00:00Z");
date = Date.from(instant);
System.out.println("Date: "+date);
System.out.println("Instant: "+instant);
System.out.println("Date epoch: "+date.getTime());
System.out.println("Instant epoch: "+instant.getEpochSecond()*1000);
