控制台错误如下：

解决这个问题有两种办法

第一种方法：

检查自己的JDK版本，打开cmd，输入java -version，查看第三行是否包含"64"，如果不包含，说明你设置的环境变量JAVA_HOME的地址指向是32位的JDK，那么你只需要下载64为的JDK并安装，然后修改环境变量JAVA_HOME指向64位的地址。此方法能一绝后患。说白了就是你的项目jdk版本与Tomcat中配置的jdk版本不一致。

 

第二种方法：

1.下载一个32位的替换   http://www.apache.org/dist/tomcat/tomcat-connectors/native/1.1.31/binaries/

2.将下载下来的文件解压，找到x64文件夹下的tcnative-1.dll文件

3.替换tomcat中bin文件夹下的tcnative-1.dll文件

此时MyEclipse中的Tomcat服务器能成功启动，但是进入Tomcat的bin文件夹下，启动startup.bat文件发现报

java.lang.UnsatisfiedLinkError: D:\apache-tomcat-7.0.56\bin\tcnative-1.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform错误。说明之前换掉的tcnative-1.dll文件出问题了。
