标签： java maven sockets tomcat

我有一个I/O exception (java.net.SocketException) caught when processing request: Connection reset by peer: socket write error问题当使用maven插件来部署tomcat时 这个问题困扰了我好几天。由于connection reset by peers错误，我无法使用tomcat7：deploy通过maven插件上传我的war文件。 这是我的pom.xml的一部分

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

并配置了远程tomcat-user.xml。

我不知道如何解决这个问题。如果有任何信息对我提供的故障排除有用，请告诉我。

提前致谢

2 个答案:

答案 0 :(得分：1)

试试这些，

  1. 使用重新部署代替部署

  2. tomcat中的默认战争大小为50 MB，如果你的战争大于50 MB，请尝试增加

  3. 列出的很多用户导致我在tomcat-users.xml中缺少角色。如果缺少Question Link

    4. ，请尝试添加经理脚本角色

  4. Tomcat7插件可能从maven conf settings.xml而不是.m2 \ settings.xml中选择服务器详细信息。在该文件中添加服务器信息可能会解决问题。

答案 1 :(得分：0)

除了@Sabir Khan的答案。 您需要检查插件配置中的服务器值是否与settings.xml中的服务器ID相同

因此，在pom.xml中，您拥有：

<plugin>
     ...
     <configuration>
          ...
           <server>MyTomcatServer</server>
          ...
     </configuration>
     ...
</plugin>

请确保您在settings.xml的行家中拥有

： 
<servers>
    ...
    <server>
        <id>MyTomcatServer</id>
        <username>username_here</username>
        <password>password_here</password>
    </server>
    ...
</servers>

否则，tomcat将尝试使用管理员帐户（如果未配置，则服务器将拒绝身份验证）
