是否有可能在运行时使用MDC命名日志文件.

我有一个Web应用程序,使用tomcat docbase同时使用不同的名称调用.所以我需要为每个文件都有单独的日志文件.

目前使用的命令是

    `sox input.wav -G -t mp3 -r 16k test.mp3`

但这是创建一个比特率为24.0 kbps的文件.

如何使输出文件的比特率达到16.0 kbps？

当我使用此函数写入csv文件时,所有数据都嵌入双引号中.

有没有办法写入没有双引号的csv文件？

CSVWriter writer = new CSVWriter(new FileWriter(table+".csv"), '\t');
            writer.writeAll(rset, true);
            writer.close();

该文件包含表单中的数据

"EMPNO" "ENAME" "JOB"   "MGR"   "HIREDATE"  "SAL"   "COMM"  "DEPTNO"    "TAG"   "LOOKUP"
"7369"  "SMITH" "CLERK" "7902"  "17-Dec-1980"   "800"   "2" "20"    "E" "1"
"7499"  "ALLEN" "SALESMAN"  "7698"  "20-Feb-1981"   "1600"  "2" "30"    "E" "2"
"7521"  "WARD"  "SALESMAN"  "7698"  "22-Feb-1981"   "1250"  "2" "30"    "E" "3"
"7566"  "JONES" "MANAGER"   "7839"  "02-Apr-1981"   "2975"  "2" "20"    "E" "2"

我正在尝试将资源复制到另一个位置.我正在使用maven wagon-ssh插件来执行此操作.它在本地工作正常,我在使用Hudson/Jenkins时遇到问题.

我的settings.xml文件看起来像这样:

<servers>
    <server>
        <id>iq</id>
        <configuration>
            <knownHostsProvider implementation="org.apache.maven.wagon.providers.ssh.knownhost.NullKnownHostProvider">
                <hostKeyChecking>no</hostKeyChecking>
            </knownHostsProvider>
        </configuration>
        <username>user</username>
        <password>pass</password>
    </server>
</servers>

我尝试了这个答案来跳过检查,因为我得到了:

Are you sure you want to continue connecting? (yes/no): The authenticity of host 'address' can't be established.
RSA key fingerprint is 10:.......:bb.

但现在我得到了:

Could not apply configuration for iq to wagon org.apache.maven.wagon.providers.ssh.jsch.ScpWagon:ClassNotFoundException: Class name which was explicitly given in configuration using 'implementation' attribute: 'org.apache.maven.wagon.providers.ssh.knownhost.NullKnownHostProvider' cannot be loaded
