我的tomcat应用程序服务器中的线程数每天都在增长.

当我采用线程转储进行分析时.

我发现在430个线程中有307个线程处于此状态.

样本堆栈跟踪

我有一个XML格式的字符串.我想阅读它并获取元素的值.

我已经尝试过Java JAXBContext unmarshell,但这需要创建类,这对我来说并不是必需的.

串:

<customer>
    <age>35</age>
    <name>aaa</name>
</customer>

我想得到年龄和名字的价值.

在RHEL 7.2 OS上,尝试运行nc commnad时出现以下错误

nc -z -v -w1 host port
nc: invalid option -- 'z'
Ncat: Try `--help' or man(1) ncat for more information, usage options and help. QUITTING.

有没有其他选择

我写了"exclude-result-prefixes",然后我在输出中看到了名称空间出现的外观.

<xsl:stylesheet
    version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt"
    xmlns:simple="Simple name space"
    xmlns:xlink="http://www.w3.org/1999/xlink"
    xmlns:tcm="http://www.tridion.com/ContentManager/5.0"
    xmlns:xh="http://www.w3.org/1999/xhtml"
    xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:transform-ext="urn:tridion:transform-ext"
    xmlns="http://www.w3.org/1999/xhtml"
    exclude-result-prefixes="#default simple xh">

实际产出

<strong xmlns="Simple name space">abcd
    <link xmlns="http://www.w3.org/1999/xhtml">
        <text>Header</text>
    </link>
</strong>

有没有任何方法可以通过编写单个语句来排除所有命名空间.

在这里我明确提到了

exclude-result-prefixes="#default simple xh"

如何避免xslt中的所有命名空间外观？

我正在研究XSLT,我需要在其中实现如下内容.My Source XML示例如下所示.

<?xml version="1.0" encoding="ISO-8859-1"?>
    <catalog>
        <cd>
            <title>A</title>  
            <title>B</title>
            <title>C</title>  
        </cd>
    </catalog>

考虑有一些关键值对列表.

    Key         Value
    A           Algebra
    B           Biology
    C           Chemistry
    D           Data Analysis
    ---         ---

    ----        ---

我需要编写一个xslt,以便每次出现键'A'时,需要用适当的值替换.

我还需要在同一个XSLT中提到Key值对的列表.样本输出:

<Data>
    <Subject>Algebra</Subject>
    <Subject>Biology</Subject>
    <Subject>Chemistry</Subject>
 </Data>

任何人都可以帮助我如何做到这一点.

谢谢.

我有一个用户定义构造函数的类.

public class Employee   
{
    @Inject
    private MyBean myBean;

    private String abcd;    

    protected Employee(Parameter1 param1, Parameter2 param2)
    { //some operations on method params
    //some operation on mybean
      this.abcd = "some value";
    }

    protected String getAbcd()
    {
        return nrOfAccesses;
    }

    protected void setAbcd(String abcd)
    {
        this.abcd = abcd;
    }

}

考试班

@RunWith(MockitoJUnitRunner.class)
public class TestEmployee
{


    @Mock
    private MyBean myBean;

    private Parameter1 param1;
    private Parameter2 param2;

    @InjectMocks
    private Employee employee;


    @Before
    public void prepare()
        throws Exception
    {
        //some intialization
        param1 = …

我正在尝试对servlet过滤器执行spring注入.过滤器是引用的jar文件的一部分.所以.我不能把它改成拦截器.在我的插件项目的web.xml中

<filter>
    <filter-name>CustomFilter</filter-name>    
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>    
    <init-param>    
        <param-name>someinitparam</param-name>    
        <param-value>value to it</param-value>    
    </init-param>
</filter>
<filter-mapping>
    <filter-name>CustomFilter</filter-name>
    <url-pattern>/mywebservices/*</url-pattern>
</filter-mapping>

在spring.xml中我将使用这样的

<bean id="CustomFilter" class="com.abc.CustomFilter"></bean>

在spring.xml中已经配置了一些过滤器

<bean id="filterChainProxy" class="org.acegisecurity.util.FilterChainProxy">
    <property name="filterInvocationDefinitionSource">
        <value>
            CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
            PATTERN_TYPE_APACHE_ANT
            /mywebservices/*=some existing filters
        </value>              
    </property>
</bean>

由于我已经在web.xml中指定了我的url模式,我需要在filterChainProxy中再次添加

/mywebservices/**=CustomFilter, some existing filters

它会起作用吗

请建议.

我试图将我的spring boot中的请求路由到另一台服务器.

我正在开发一个Web服务.我想将401: Unauthorized响应返回给用户以获取无效凭据.

如何手动返回此响应代码？

我正在使用bootstrap模式来显示消息.

 var options = {
          backdrop: false,
          keyboard: true,
          backdropClick: false,
          templateUrl: 'a.html',
          controller: 'aController',  
        };
 var modalInstance = $modal.open(options);

是否可以提供自定义宽度和高度样式属性.
