Tomcat 9.0.34 的 Gradle 插件

Question

我正在尝试使用https://github.com/bmuschko/gradle-tomcat-plugin启动我的应用程序。

我的 gradle 配置如下所示：

apply plugin: 'com.bmuschko.tomcat'

ext.tomcatVersion = '9.0.30'

dependencies {
    // some dependencies

    tomcat "org.apache.tomcat.embed:tomcat-embed-core:$tomcatVersion",
            "org.apache.tomcat.embed:tomcat-embed-logging-juli:9.0.0.M6",
            "org.apache.tomcat.embed:tomcat-embed-jasper:$tomcatVersion",
            "org.apache.tomcat:tomcat-jdbc:$tomcatVersion",
            "org.apache.tomcat:tomcat-dbcp:$tomcatVersion"
}

tomcat {
    httpProtocol = 'org.apache.coyote.http11.Http11Nio2Protocol'
    ajpProtocol  = 'org.apache.coyote.ajp.AjpNio2Protocol'
    httpPort = 8088
}

使用 Tomcat 版本高达9.0.30它运行顺利，但最新的9.0.31+引发以下异常（为简洁起见）：

Caused by: java.lang.IllegalArgumentException: The AJP Connector is configured with secretRequired="true" but the secret attribute is either null or "". This combination is not valid.

如何摆脱它？ 这可以通过配置更改来解决吗？ 是否有任何 tomcat 插件叉可以很好地处理它，或者可能是 tomcat 的另一个 gradle 插件？

Answer 1

尝试更换

ajpProtocol  = 'org.apache.coyote.ajp.AjpNio2Protocol'

和

ajpProtocol = 'org.apache.coyote.http11.Http11Nio2Protocol'

这将允许 bmuschko 绕过 AJP 连接器协议。
