雄猫管理器脚本部署大型战争不起作用

Question

我正在尝试通过使用管理器脚本servlet上传WAR来自动部署tomcat 8.0.12中的WAR。

对此 URL 执行 PUT 操作：

http://tomcaserver:8080/manager/text/deploy?path=/myApp&update=true

我的WAR大小约为80mb，我认为这就是问题所在。

我使用小型 WAR（约 500kb）进行了测试，它可以毫无问题地上传。

我已经尝试在/webapps/manager/WEB-INF/web.xml 中指定多部分配置，插入以下内容：

<servlet>
  <servlet-name>Manager</servlet-name>
  <servlet-class>org.apache.catalina.manager.ManagerServlet</servlet-class>
  <init-param>
    <param-name>debug</param-name>
    <param-value>2</param-value>
  </init-param>
  <multipart-config>
    <!-- 200MB max -->
    <max-file-size>209715200</max-file-size>
    <max-request-size>209715200</max-request-size>
    <file-size-threshold>0</file-size-threshold>
  </multipart-config>
</servlet>

在此之后，问题仍然存在。

我正在使用Apache HTTPClient上传，这是例外：

这是我的代码：

    String url = "http://tomcatserver:8080/manager/text/deploy?path=/organize&update=true";
    HttpPut req = new HttpPut(url);
    MultipartEntityBuilder meb = MultipartEntityBuilder.create();
    // upload the big war (80mb)
    meb.addBinaryBody("attachment", war, ContentType.APPLICATION_OCTET_STREAM, "myApp.war");
    req.setEntity(meb.build());
    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("tomcat", "s3cret"));
    CloseableHttpClient client = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
    CloseableHttpResponse resp = client.execute(req); <<<---- EXCEPTION!

我该如何解决这个问题？

问题是您构建文件上传的奇怪方式。我不知道"附件"会做什么，但HTTP PUT是正确的。

试试这个：

String url = "http://tomcatserver:8080/manager/text/deploy?path=/organize&update=true";
HttpPut req = new HttpPut(url);
File war = new File("myApp.war");
req.setEntity(new FileEntity(war, ContentType.APPLICATION_OCTET_STREAM));
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("tomcat", "s3cret"));
CloseableHttpClient client = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
CloseableHttpResponse resp = client.execute(req);
