Tomcat运行启动异常：A child container failed during start java.util.concurrent.ExecutionException

### JDK1.8+Tomcat8.0 +Eclipse+SSM+Maven ###

启动Tomcat站点，有异常（无论是“重启eclipse”还是重启“电脑”，异常没有解决）：

问题出现之后，我先是查看“端口8080”是否被进程占用，没有！！！

接着我去启动关闭Tomcat8试试，

Stop的按钮就会亮起，紧接着我点击Stop按钮；然后，我去重启eclipse的站点，还是报错，但是，我去查看端口8080占用情况，发现8080端口被“0端口”进程占用了，并且显示“TIME\_WAIT”状态，

> 百度：[TCP 连接的 TIME\_WAIT 过多 导致 Tomcat 假死][TCP _ TIME_WAIT _ _ Tomcat]

（我顺便查看了有多少进程处于TIME\_WAIT状态【在[MySQL 调优基础(五) Linux网络][MySQL _ Linux]中拷贝的命令】：![20190912174621350.png][]）

补充：端口8080正常被占用时，可以终止进程：（状态是 ESTABLISHED 已设定的、已建立的、被安排好的）

![20190912180216177.png][]

我百度了一下，我觉得（在Win7系统）答案并不是那样的：

然后我抛开“Time\_Wait”的问题，根据“控制台弹出的异常”来查找答案：

发现：

我符合文章的第二种情况：![20190912195146737.png][]

### 我的第一解决方案： ###

检查自己的“Dynamic Web Module”版本，一般是：3.0的Dynamic Web Module、1.8的jdk、8.0或8.5的Tomcat；

从图可知，我的Dynamic Web Module是2.3版本，与上图版本不一致，而jdk为1.8版本，搭配有问题【其实创建项目或者导入项目，都要检查版本的，eclipse有时莫名其妙，这次就是把我的Dynamic Web Module恢复eclipse的默认版本号2.3，选项最低为2.2版本号】，则Dynamic Web Module改成3.0，你若直接选择3.0，apply控件会变灰色，且有个框弹出并提示“Cannot change version of project facet Dynamic Web Module to 3.0”【椭圆框内，表示Dynamic Web Module3.0版本搭配1.6以上版本的jdk】

** 改：（你找不到文件，可以使用‘文件管理器’的搜索框直接搜索，选择对应项目的‘.setting’文件夹下的两个org.eclipse.jdt.core.prefs.prefs、org.eclipse.wst.common.project.facet.core文件）**

找到工作空间中的项目，打开项目找到.settings文件夹打开，编辑两个文件：
    
    1.org.eclipse.jdt.core.prefs.prefs文件中的：
    
    eclipse.preferences.version=1
    org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled
    org.eclipse.jdt.core.compiler.codegen.methodParameters=do not generate
    org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.8
    org.eclipse.jdt.core.compiler.codegen.unusedLocal=preserve
    org.eclipse.jdt.core.compiler.compliance=1.8
    org.eclipse.jdt.core.compiler.debug.lineNumber=generate
    org.eclipse.jdt.core.compiler.debug.localVariable=generate
    org.eclipse.jdt.core.compiler.debug.sourceFile=generate
    org.eclipse.jdt.core.compiler.problem.assertIdentifier=error
    org.eclipse.jdt.core.compiler.problem.enumIdentifier=error
    org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning
    org.eclipse.jdt.core.compiler.source=1.8
    
    将1.8修改成对应的jdk版本
    
     
    
    2.org.eclipse.wst.common.project.facet.core.xml文件中：
    
    <?xml version="1.0" encoding="UTF-8"?>
    <faceted-project>
    <runtime name="Apache Tomcat v8.5"/>
    <fixed facet="wst.jsdt.web"/>
    <installed facet="wst.jsdt.web" version="1.0"/>
    <installed facet="java" version="1.8"/>
    <installed facet="jst.web" version="3.0"/>
    </faceted-project>
    
    将这个<installed facet="java" version="1.8"/>改成对应的java版本号，<installed facet="jst.web" version="3.1"/>改成对应的Dynamic Web module的版本号。
    
    然后再打开project facet 查看是否修改。

改了之后，重启eclipse，运行站点，成功，但是我接下来没有用eclipse或者访问站点，隔个十几分钟，我访问相应页面，404！！！奇怪，成功运行了站点，怎么404,（非常肯定不是我的页面有问题，不是我的Controller访问方式有问题），接着我重新运行Tomcat站点，报错，重复‘一开始报的错’，然后我查看端口8080，又是Time\_Wait状态！！！

### 【可能别人改完版本号，就完完全全好了，反正我的这个，No~】 ###

![20190912175930358.png][]

### 第二解决方案： ###

上面那么解决方案，对我的问题，似乎是“治标不治本”，然后看了个论坛，很简单的回复，反正根据提问者的答案，我解决了！！！

确实“简单暴力，直接了当”！！！我右击Tomcat，选择delete，然后点击servers窗口里的带下划线的链接，new一个Tomcat——》Next或者直接Finish———》（我选择Next）在左边框里，选择对应项目——》add添加至右边的框里——》Finish——》根据你个人情况，选择调试还是直接运行，我个人喜欢选择调试，因为断点可以设置跳过【![20190912201714580.png][]】！！！

补充:

（若选择Finish，![20190912201851336.png][]选择Tomcat server右击——》选择Add and Remove 即可添加项目）
