apache-jmeter的设置允许将URL发送到多个线程上的Web服务器.我有兴趣首先确定响应代码是否为200-500,然后确定返回的内容是否是预期内容.这种详细配置是否可行？
我需要从外部源插入一个日期格式,其中包括时区的三个字母代码,但TZD格式化掩码似乎不起作用...
insert into blah
values (to_date('Thu, 18 Feb 2010 08:37:00 EST','Dy, DD Mon YYYY HH24:MI:SS TZD'));
ORA-01821: date format not recognized
如果我删除"TZD"......
insert into blah
values (to_date('Thu, 18 Feb 2010 08:37:00','Dy, DD Mon YYYY HH24:MI:SS'));
1 row created.
Oracle中这种insert语句的正确掩码是什么？
desc blah
Name Null? Type
----------------------------------------- -------- ----------------------------
D DATE
编辑:我将表列从DATE类型更改为TIMESTAMP类型并得到相同的错误.
我有一个对象数组，每个对象都有一个左右元素。在某些情况下，数组内的左边可能等于右边，对于数组内的不同对象，反之亦然。需要删除这些“重复项”。
例如，我有一个像这样的对象数组......
[
{"left":"cow","right":"pig"},
{"left":"horse","right":"pig"},
{"left":"rabbit","right":"pig"},
{"left":"bird","right":"pig"},
{"left":"bear","right":"pig"},
{"left":"cow","right":"bird"},
{"left":"horse","right":"bird"},
{"left":"pig","right":"bird"},
{"left":"cow","right":"horse"},
{"left":"bird","right":"horse"},
{"left":"pig","right":"horse"},
{"left":"rabbit","right":"horse"},
{"left":"horse","right":"cow"},
{"left":"pig","right":"cow"},
{"left":"bird","right":"cow"},
{"left":"bear","right":"cow"},
{"left":"horse","right":"rabbit"},
{"left":"pig","right":"rabbit"},
{"left":"bear","right":"rabbit"},
{"left":"pig","right":"bear"},
{"left":"rabbit","right":"bear"},
{"left":"cow","right":"bear"}
]
我需要将它过滤到唯一的对，就像这样......
[
{"left":"cow","right":"pig"},
{"left":"horse","right":"pig"},
{"left":"rabbit","right":"pig"},
{"left":"bird","right":"pig"},
{"left":"bear","right":"pig"},
{"left":"cow","right":"bird"},
{"left":"horse","right":"bird"},
{"left":"cow","right":"horse"},
{"left":"rabbit","right":"horse"},
{"left":"bear","right":"cow"},
{"left":"bear","right":"rabbit"}
]
使用javascript。
我试图阻止...
[localhost-startStop-1] org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
...由于我没有定义 TLD，因此出现我的 war 文件部署时出错。
关于这个问题有很多问题和答案，但它们似乎都指向改变 Tomcat 的全局配置，这是我不想要的。
我如何通过我的 war 文件的本地 context.xml 文件通知扫描器不存在 TLD，因此扫描和后续警告是不必要的？
说我有以下XML ...
<root>
<base>
<tent key="1" color="red"/>
<tent key="2" color="yellow"/>
<tent key="3" color="blue"/>
</base>
<bucket>
<tent key="1"/>
<tent key="3"/>
</bucket>
</root>
... XPath会返回"bucket"包含"red"和"blue"的内容？
我已经在APEX上安装了Oracle XE,但是忘了写下访问它的URL.我该如何确定网址？
在Oracle中我可以声明一个引用游标......
TYPE t_spool IS REF CURSOR RETURN spool%ROWTYPE;
...并使用它将光标作为返回值传递...
FUNCTION end_spool
RETURN t_spool
AS
v_spool t_spool;
BEGIN
COMMIT;
OPEN v_spool FOR
SELECT
*
FROM
spool
WHERE
key = g_spool_key
ORDER BY
seq;
RETURN v_spool;
END end_spool;
...然后使用JDBC将其作为结果集捕获...
private Connection conn;
private CallableStatement stmt;
private OracleResultSet rset;
[...clip...]
stmt = conn.prepareCall("{ ? = call " + call + "}");
stmt.registerOutParameter(1, OracleTypes.CURSOR);
stmt.execute();
rset = (OracleResultSet)stmt.getObject(1);
MySQL中的等价物是什么？
我需要为服务器监控过程组成一个相当简单的GUI.它将有一些选项卡,可以导致日志拖尾,资源计数以及启动和顶部控制.没什么好看的.哪个Java框架,AWT或Swing对于这么简单的事情更有意义.
我正在使用<%=request.getRemoteUser()%>Tomcat中检索登录用户的ID.使用JSP简单表达式语言会等同于什么？
我正在使用 Saxon 9 在 Java 中执行 XSL 转换。如果在转换过程中出现错误，Saxon 会将输出定向到运行它的 JVM 的标准错误流。我的 Java 应用程序具有用于标准输出和错误的日志记录机制。如何强制 Saxon 使用我的错误输出流而不是 JVM 默认错误输出流？
