jakarta-ee - tomcat：部署：“无法调用 Tomcat 管理器：连接被拒绝”

Question

我尝试使用 Maven 将我的应用程序部署到 Tomcat，并且我找到了这个示例。

那是我的 pom.xml 的片段：

    <!-- Maven Tomcat Plugin -->
    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>tomcat-maven-plugin</artifactId>
        <configuration>
            <url>http://127.0.0.1:8080/</url>
            <server>TomcatServer</server>
        </configuration>
    </plugin>
    <!-- Maven compiler plugin -->
    <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.6</source>
            <target>1.6</target>
        </configuration>
    </plugin>

当我运行时，tomcat:deploy我得到这个错误：Cannot invoke Tomcat manager: Connection refused。这是完整的堆栈跟踪：

[ERROR] Failed to execute goal org.codehaus.mojo:tomcat-maven-plugin:1.1:deploy (default-cli) on project webapp: Cannot invoke Tomcat manager: Connection refused: connect -> [Help 1]

我不想使用身份验证，所以我只是跳过了这些步骤。我认为这可能会导致我的错误，但是当我尝试添加它们时，没有任何改变。你知道我的错在哪里吗？

UPD：抱歉，我无法检查我们的解决方案，因为我不再从事这个项目了。但是我不会关闭这个问题，所以如果您认为您的解决方案可以工作，请随时将其留在这里，并且可能会对某人有所帮助。

Answer 1

使用 tomcat 7 插件时，请执行以下操作：

pom.xml

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <url>http://localhost:8080/manager/text</url>
        <server>tomcatserver</server>
        <path>/mycontext</path>
        <username>admin</username>
        <password>admin</password>
    </configuration>
</plugin>

设置.xml

<server>
    <id>tomcatserver</id>
    <username>admin</username>
    <password>admin</password>
</server>

tomcat-users.xml

<user username="admin" password="admin" roles="manager-script"/>

跑

mvn tomcat7:deploy

Answer 2

我有同样的问题。在我的情况下，我使用 runrun-war而不是deploy配置 Tomcat7 来修复它：

         <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <url>http://localhost:8080</url>
                <path>/</path>
            </configuration>
        </plugin>

Answer 3

用Tomcat 7机制理解 maven 插件部署需要一段时间，但它的工作原理如下：

与命令一起使用：

mvn tomcat7：部署

必须先初始化Tomcat服务器！您可以选择从 IDE 启动或在位于文件夹 %TOMCAT_HOME%\bin 的启动脚本中启动

运行它的输出应该如下所示：

mvn tomcat7:run-war

Tomcat 不需要初始化，因为上面的脚本会自动启动服务器。但是，将不会启用上下文/manager以在浏览器中使用。

运行它的输出应该如下所示：

您甚至可以运行命令mvn clean package来执行项目的先前清理。

一些额外的配置：

[%TOMCAT_HOME%\conf] tomcat-users.xml

<role rolename="tomcat"/>
<role rolename="admin-script"/>
<role rolename="manager-script"/>
<role rolename="manager-gui"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<role rolename="manager"/>
<role rolename="admin"/>

<user password="tomcat" roles="tomcat" username="tomcat"/>
<user password="admin" roles="manager-gui" username="admin"/>
<user password="pass@word1" roles="admin,admin-script,manager-gui,manager-script,manager-jmx,manager-status" username="mavenuser"/>

[%MAVEN_HOME%\conf] 设置.xml

<server>
    <id>your_server</id>
    <username>mavenuser</username>
    <password>pass@word1</password>
</server>

[%project%] pom.xml

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <url>http://localhost:8080/manager/text</url>
        <server>your_server</server>
        <path>/project_context</path>
        <username>mavenuser</username>
        <password>pass@word1</password>                 
    </configuration>
</plugin>

希望能帮助到你！

Answer 4

我遇到了同样的问题，它似乎是 Tomcat 版本与 Maven 插件版本。我使用了 tomcat 7 并尝试使用tomcat:deploy-only而不是tomcat7:deploy仅进行部署。如果这是您的情况，请尝试tomcat7:deploy-xxx。

Answer 5

我认为这里很重要的一点是，您应该使用 tomcat 7 :deploy。不要小看7。

我使用的是自动完成，总是以 tomcat:deploy 结束，只是盲目地忽略了小 7。

Answer 6

我查看了tomcat(dir:)的日志，log/localhost_access.xxx发现maven上传.wawr文件到tomcat时，响应的http状态码是403，表示访问被禁止。

然后我检查了managerandhost应用程序是否具有相同的 dir: META-INF。在这个目录中，我找到了文件context.xml，这个文件限制了manager和hostapp的访问。关键文本如下：

<Context antiResourceLocking="false" privileged="true" >
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

修改属性allow让你的ip访问manager和hostapp，问题就解决了。

Answer 7

因此，当我使用 mvn tomcat7:deploy 时，尽管一切都已正确配置，但我遇到了这个问题。

问题是在部署之前我必须取消部署，即 mvn tomcat7:undeploy，然后是 tomcat7:deploy。

哎呀！这是一个如此疯狂的错误。

Answer 8

如果问题是因为 Java 堆空间。如果它是作为服务安装的，那么您可以使用以下步骤更改它：

1- 从 cmd "Tomcat_DIR\tomcat6w.exe" //ES//ServiceName 运行

2-它将打开tomcat GUI。在 JAVA 菜单中，给出内存池配置。

将为 Tomcat 保留那么多内存。它应该可以解决您的内存堆问题。
