任何人都可以帮我解决我的tomcat运行错误，当我运行tomcat时出现以下错误：

你的一个依赖项包括一个servlet-api到你的war文件中，这导致了这种行为。使用mvn dependency：tree，你可以找出你的依赖关系。之后，您需要按如下方式排除servlet-api：
<dependency>
<groupId>[VALUE]</groupId>
<artifactId>[VALUE]</artifactId>
<version>[VALUE]</version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
你需要为其他servlet-api（例如org.mortbay.jetty：servlet-api，..）执行此操作。

我可以通过从部署程序集中删除servlet-api.jar来解决这个问题（在eclipse中）
MY-web的项目 - ＆GT;属性 - ＆gt;部署程序集
并删除它。其他人声明，在maven项目中，servlet-api依赖的范围必须设置为“提供”

当我添加CXF的依赖项时，我遇到了类似的问题。我尝试了以上推荐的方法从该依赖项中排除javax.servlet，但它没有用 - 但是添加提供解决了它。 这可能是一个不同的情况，但值得一试。
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-bundle-jaxrs</artifactId>
<version>2.2.9</version>
<scope>provided</scope>
</dependency>
如果我回答了你的问题，请注明。 ;）

通过排除geronimo解决了类似问题。
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-http-jetty</artifactId>
<version>3.0.3</version>
<exclusions>
<exclusion>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-servlet_2.5_spec</artifactId>
</exclusion>
<exclusion>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-servlet_3.0_spec</artifactId>
</exclusion>
</exclusions>
</dependency>
确定哪些jar文件包含通过扫描WEB-INF / lib文件夹中包含的类的每个jar文件找到的错误。即。
jar tvf <jar-file>
答案 4 :(得分：0)
可能在您配置的web.xml中
// The following arrays are for use with UISegmentedControl (other three removed for brevity)
// This is an array of 'Appearance' list items created from allListItems
let appearanceArray = allListItems.filter{
$0.category.rangeOfString("Appearance") != nil
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath:
NSIndexPath) -> UITableViewCell {
let cellIdentifier = "Cell"
let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! AllListItemsTableViewCell
// This is a string value for the cell at indexPath.row
var listItemInCell = ""
// This is an array of all listItems in allListItems, and used with indexOf to check boolean status of isSelected inside of allListItems array
let arrayAll = allListItems.map{($0.listItem)}
// This is an array of all listItems in selectedListItems, and used to track remove indexes
let arraySelected = selectedListItems.map{($0.listItem)}
switch(segmentedControl.selectedSegmentIndex)
{
case 0: // Case 0 of 4, the others removed for brevity of this question
listItemInCell = appearanceArray[indexPath.row].listItem
// Index of listItemInCell inside of the array of allListItems' listItems
let indexOf = arrayAll.indexOf(listItemInCell)!
cell.listItemLabel.text = listItemInCell
// Tracks UISwitch activity
cell.callback = { (tableViewCell, switchState) in
if self.tableView.indexPathForCell(tableViewCell) != nil {
// do something with index path and switch state
if switchState == true {
allListItems[indexOf].isSelected = true
selectedListItems.append(self.appearanceArray[indexPath.row])
} else {
allListItems[indexOf].isSelected = false
let indexInSelected = arraySelected.indexOf(listItemInCell)!
selectedListItems.removeAtIndex(indexInSelected)
}
}
}
if appearanceArray[indexPath.row].isSelected {
cell.toggleIsSelected.on = true
} else {
cell.toggleIsSelected.on = false
}
break
但它是过滤器。所以将servlet更改为过滤器。
