问题描述

我正在尝试通过 eclipse luna 将 Web 应用程序部署到 tomcat7，但出现此错误:

I am trying deploy a web application to tomcat7 via eclipse luna, but I am getting this error:

我也尝试部署到 tomcat8，但我遇到了同样的错误.

I also try deploy to tomcat8, but I get this same error.

在我的 pom.xml 中，我有这个操作相关的配置:

In my pom.xml, I have this configuration related to this operation:

  <build>
    <finalName>loja</finalName>
    <plugins>
        <plugin>
           <groupId>org.apache.tomcat.maven</groupId>
           <artifactId>tomcat7-maven-plugin</artifactId>
           <version>2.2</version>
           <configuration>

            </configuration>
        </plugin>
    </plugins>
</build>

有人知道这里发生了什么吗?

Anyone knows what's happening here?

更新

我尝试使用命令 mvn:tomcat7 deploy -X 部署应用程序，输出如下:

I try deploy the application with the command mvn:tomcat7 deploy -X and the output was that:

推荐答案

默认情况下，Tomcat 的最大上传大小为 50MB.(即 WAR 文件的最大大小)

By default Tomcat has a max upload size of 50MB. (I.e max size of WAR file)

如果您需要更大的文件，请尝试在 tomcat web.xml 中增加 max-file-size 和 max-request-size.注意:这些值都以字节为单位存储.

If you require larger file, try increasing max-file-size and max-request-size within the tomcat web.xml. Note: those values are both stored in bytes.

编辑 .../webapps/manager/WEB-INF/web.xml.(确保文件大小大于您尝试上传的 war 文件).即如果您需要 80MB WAR，

Edit .../webapps/manager/WEB-INF/web.xml. (Ensure the file sizes are larger than the war file your trying to upload). I.e if you require 80MB WAR,

  <max-file-size>82914560</max-file-size>
  <max-request-size>82914560</max-request-size>

然后重启apache tomcat.

Then restart apache tomcat.
