tomcat中的资源定义server.xml看起来像这样......

<Resource
    name="jdbc/tox"
    scope="Shareable"
    type="javax.sql.DataSource"
    url="jdbc:oracle:thin:@yourDBserver.yourCompany.com:1521:yourDBsid"
    driverClassName="oracle.jdbc.pool.OracleDataSource"
    username="tox"
    password="toxbaby"
    maxIdle="3"
    maxActive="10"
    removeAbandoned="true"
    removeAbandonedTimeout="60"
    testOnBorrow="true"
    validationQuery="select * from dual"
    logAbandoned="true"
    debug="99"/>

密码是明确的.怎么避免这个？

我想列出指定目录中的所有FILES和该目录中的子目录.不应列出任何目录.

我目前的代码如下.它无法正常工作,因为它只列出指定目录中的文件和目录.

我怎样才能解决这个问题？

final List<Path> files = new ArrayList<>();

Path path = Paths.get("C:\\Users\\Danny\\Documents\\workspace\\Test\\bin\\SomeFiles");
try
{
  DirectoryStream<Path> stream;
  stream = Files.newDirectoryStream(path);
  for (Path entry : stream)
  {
    files.add(entry);
  }
  stream.close();
}
catch (IOException e)
{
  e.printStackTrace();
}

for (Path entry: files)
{
  System.out.println(entry.toString());
}

问候.

如何在java spring框架中注入Map？如果可能,请提供一些示例代码.

以下是合法的吗？

<property name="testMap">
    <map>
        <entry>
            <key>
                <value>test</value>
            </key>
            <value>
                <list>
                    <value>String</value>
                    <value>String</value>
                </list>
            </value>
        </entry>
    </map> 
</property>

是否可以在不使用Bouncy Castle X509V*CertificateGenerator类的情况下巧妙地创建Java代码的X509证书？

我已经部署了一个Apache Wicket Web应用程序,它将Spring和Hibernate用于我的Tomcat 5.5实例.当我导航到Tomcat Manager界面时,我发现我部署的Web应用程序没有运行.当我按下"开始"时,我收到以下错误消息; "失败 - 在上下文路径/意大利面条中的应用程序无法启动".

我的catalina.log包含以下内容:

Apr 15, 2010 1:51:22 AM org.apache.catalina.loader.WebappClassLoader validateJarFile

摘自web.xml: …

我有一个属性文件,其中值的顺序很重要.我希望能够遍历属性文件并根据原始文件的顺序输出值.

但是,由于属性文件是后备的,如果我错了,请更正我,不保持插入顺序的Map,迭代器以错误的顺序返回值.

这是我正在使用的代码

Enumeration names = propfile.propertyNames();
while (names.hasMoreElements()) {
    String name = (String) names.nextElement();
    //do stuff
}

无论如何,除了编写我自己的自定义文件解析器之外,是否还要恢复属性？

我试图从下面的文件中提取RES公钥

这是我做的代码..

public static PublicKey loadPublicKeyFromFile(File publicKeyFile) throws Exception {

    FileReader file = new FileReader(publicKeyFile);
    PemReader reader = new PemReader(file);
    X509EncodedKeySpec caKeySpec = new X509EncodedKeySpec(reader.readPemObject().getContent());
    KeyFactory kf = KeyFactory.getInstance("RSA");
    PublicKey caKey = kf.generatePublic(caKeySpec);
    return caKey;
}

但它抛出了

java.security.InvalidKeyException:IOException:ObjectIdentifier() - 数据不是对象ID

从文件中提取RES公钥的适当方法是什么？

错误：“ModalBottomSheetRoute”是从“package:flutter/src/material/bottom_sheet.dart”和“package:modal_bottom_sheet/src/bottom_sheet_route.dart”导入的。

导入'material.dart'隐藏ModalBottomSheetRoute；

我正在使用maven-ear-plugin版本2.3.1 - 我知道有一个新版本可用:http://maven.apache.org/plugins/maven-ear-plugin/

我无法弄清楚如何升级到最新版本？
